Hello all. After months of being a shifty sort of person on the forum, particularly the barge thread, I've finally gone out and bought myself a totally unnecessary car. Again.

I have a bit of previous with this - I've had an 07-plate Skoda Roomster for ten years which has been great and done all the (sometimes unusual) things I've asked of it. But I've been into cars for a long time - not necessarily fast ones; in fact, generally quite the opposite. My car history has included a Flintstones '56 Morris Minor, my first drive-on-the-road car was a '68 Triumph Herald, a brace of Volvo 340/360s bought for £30 total, then a gold-tastic Toyota Town Ace (Royal Lounge Limited, no less) which was sublime yet hugely slow, and a Mitsubishi Delica in full LWB glory. Alongside that little lot, I've had a few oddball bikes - a BMW C1 & Piaggio MP3 amongst others.

Anyway, I digress. I've recently bought a '96 Mercedes E300 estate (W124 multivalve 4-speed flavour). And it's been....interesting.

I hadn't test driven any cars until recently but had been looking to get something in addition to my Skoda. I was thinking of a 986 Porsche Boxster or R129 Mercedes SL, as I haven't owned a convertible, but the W124 MBs have always struck me as an elegant design and have a good reputation.

The first car I drove was an unusual green Mercedes 190, which was on eBay nearby and actually parked at the station near where I work. Interesting car, but I wasn't sure about the reason for the swift resale, the colour (described to me as 'bogey green') or a few details, including a driver's bolster that was worn through several layers.

After that, I tried a Boxster. The car I tried was pretty good value (hard top, heated seats, low miles, 3.2S, decent price) but somehow didn't grab me as much as I was expecting. In addition, the convertible side of things appealed, but I'm not a speed merchant so a fast car was perhaps not one that would get it's intended use with me.

Then this car - which I'd already seen on eBay & Gumtree - came back up for sale, just a few miles away from me. To shorten a long story, I went to view and drive, and kinda fell in love with the thing. It's cosmetically scruffy - damaged lacquer, hole in front wing, and so on - but the owner seemed genuine and rattled off a list of various items replaced during his 12-year ownership. And it ended up cheap, so I bought it.

So....

I went to collect the car last Tuesday. Handover went well, and I proudly drove off in my first ever Benz. Off for a wash, expecting that the condensation (car not used much for a year) would clear up with some heat.

...but life had other plans. Since buying the car, I've found that there are some things that need more timely attention than I anticipated.

First of all, I thought I'd been struck down by the dreaded ball joint issue: as I was getting home, I noticed some noise & grumbling on quarter-turn corners. That seems to be due to a power steering leak (or, at least, it's exacerbated by one) so that's the first thing to get attention.

Next up: welding. I took the car to a garage on Thursday for advice and they've quoted me £1k for rear subframe area welding. Second opinion will be obtained...

Next: garage quoted for £600 of brake pipe work - front to rear pipe, pipes to the wheels & labour.

Next: there's no heat in the cabin, but the car it running at the right part of the gauge. It doesn't look to be the duo valve (yet) as all the hoses in that area are cold, even after a 30 mile run. Given the top rad hose looks crumpled when cold, I imagine the feed to the heater isn't working to spec.

After that, there's a vibration to the steering wheel, which might be caused by the tyres (which,if I'm reading them right, are up to 16 years old!), and possibly something in the drivetrain.

Sooooo..... I wouldn't say that I've bought a pup. For a late W124 diesel estate, I imagine I'd get a decent chunk of the outlay back if it came to it. In the meantime, despite its faults I am enjoying the experience and can see the appeal of barge life.

Car goes off to a specialist in a few days - I hope, once I've booked it in - and we shall see.

Comments, suggestions, tea, biscuits, offers of help, reinforcements that I'm a numpty - all are welcomed!

Now, some things are - for now, at least - out of my hands & comfort zone: locating the PS leak is one of those. The need for (and urgency of) welding is another. But one of the reasons for getting the car was to be able to get more involved in fixing and improving a car, and I'm keen to get stuck in where I can.

So, I have tyres planned (Michelin Cross Climates are £65 fitted per corner - that'll do nicely), and I'd like to tackle the heater problem if/when the time comes to proceed with the car. I'm expecting that replacing the water hoses would be the best start, at least to the point where they enter the heater or duo valve. I do need to look at the rear side window sealing, as it seems that water is getting in through them. And a service is on the cards.

I have no hard feelings for the previous owner - he seemed genuine, but was selling because the car wasn't getting used and had only had basic servicing in the last couple of years. It did sound & feel like the car was fairly together - all the buttons inside worked, and so on - and the car seemed in reasonable shape for its 310k miles. So we shall see what the specialist has to say, and how far I want to spend time & money on restoration.

In the mean time, does anyone know what these buttons should say & what they do? The middle one used to have a snowflake on it, but I have no clue what each is supposed to accomplish (and, with no heat coming in, their function isn't made clear by any appreciable change). Thanks!

Thanks, all, and apologies for the slow response - PH has been on a noob-posting freeze again.

I've now joined the owners' club, got the Haynes manual, have a replacement fuel cap which will be going on shortly (because that's more important than silly power steering or not freezing to death), and the car's going in to be looked at on Tuesday.

In the meantime, I'm trying to work out which bits I need to order - I'm thinking that I want to replace the coolant hoses & PS pipes, plus the aerial grommet as the start of chasing down the condensation issue. Any tips on chasing down the right part numbers & decent parts suppliers would be much appreciated. r129sl of this establishment has already been very helpful, although I think some of the links on his titivation thread are now not working (but it could be me).

Anyway, barring a horrendous welding quote next week, I'm planning to give the old thing a bit of love. I'm enjoying it so far.

So. We have progress!

The car has been in to a specialist today. Work is needed but, aside from the heating (duh) and the power steering leak (~1.5l in 240 miles), none of the work is urgent.

I'm awaiting the price for the replacement steering line in the morning, likewise the diagnosed replacement duo valve. Although the valve may be fixable, and I have a secondhand one on its way to me.

Other noted snags are:

- Front indicator bulbs aren't orange any more;
- Cracked rear light;
- Rear washer not working (might be out of fluid - not sure they checked);
- Boot struts need replacing;
- Wheel balancing needed;
- Tyre;
- Slight play in steering idler bush (damper?);
- Corrosion (but not serious) on suspension pipes, underside and in the rear subframe area;
- Exhaust centre box & rear box corroded (I think he said holed over the phone);
- Minor water pump leak.

So, not all doom & gloom, but some things to do.

Obviously, I immediately went onto ECP and bought wiper blades, glass cleaner & wax.

Seems relevant.

Oh, and I have a set of CrossClimate+ going on on Saturday. And I'll order a replacement aerial grommet from MB as half is missing.

The PS line will get done, I'll have a play with the duo valve, keep an eye on the coolant level, and make a start on the jobs I can have a shot at.

Looking forward to having working heating, though - hopefully it'll help with the condensation problem the car has.

Not a bad day (car-wise, at least). Hooray!

Thank you, sir. Very useful.

Bulbs will hopefully be fitted after work tomorrow, and I may try to screw up the duo valve completely while I'm there. I mean: adjust it. I've even bought a multimeter (although I have no idea what to do with it, and only a vague memory of what it should read if the electrical side of things is working - 12V difference between the centre and each side pin when set on full hot, n'est-ce pas?). I do have a secondhand valve incoming, although I don't know whether it's the correct fit (I'm told it is) or complete & working (I'm not told it isn't). Might be a useful source of spare parts, if nothing else. I think I'm right in saying that removing the moving valve jobbies should make the heating come full on...? That'd be nice. I can't hear the solenoids moving, so either the electrical side is kaput or the mechanical side isn't shifting. I think.

For corrosion & exhaust, I'll probably get a local mechanic I've used to have a look. He's sensible, happy to look things up online, reasonably priced, and would show me under the car on the lift (which I know some places wouldn't do). Hopefully the exhaust can be repaired to eke out a little more life before replacement, although Eberspacher replacement sections would run to about £250 for the two, so that's not bad. But the PS has to come first.

On that subject, I'm not sure whether I'm slightly disappointed in the specialist: when I rang yesterday mid-afternoin to check progress, I asked them to price up the PS repair and duo valve, and was expecting to talk about it when I went back to swap cars (borrowed a nice P reg C class). Now, I know I got there at 17.20 and they closed at 17.30, but I felt chivvied out of the door, and no pricing given. They were going to get the prices and call me. Called again this afternoon, and they've been very busy so would call me later. Haven't heard anything. Hmm. On top of reporting the non-working rear squirter, but then not having checked there was any fluid (okay, there's a boot liner, but still), it's not feeling entirely like they want my money. Fair enough they're busy, but I want the PS fixed! I'll check in with my local man tomorrow.

Rear lamp: repair tape bought, hopefully to be installed tomorrow night. That'll hold it until I get hold of a replacement.

Tyres are going on at an unearthly hour of Saturday morning. Alignment will be done, but can't be done on Sat. I'll ask that garage (someone else again!) to price up the idler bush and steering damper jobs as part of the alignment. Although I guess the damper won't affect that? May have a go myself, if I get myself some ramps. The idler bushes look slightly more involved.

Interestingly, from looking through the wodge of receipts I was given (bought?) with the car, various things were indeed mentioned...but happened some time ago. Suspension spheres have been done, but a while back. I'll get them looked at, but I'm reassured that the back end isn't about to fall off. The 16-year-old tyre has but days left on the car...

Boot struts aren't hugely pressing, in that the boot stays up without the hand of man. I'm not sure how heavy it should feel - I think it's heavier than it should be, but there's no easy way to find out. Willing to give it a go, but currently not a priority.

I'm glad that I haven't bought a lemon and, as the car has got this far, I'm glad to be able to keep it going a bit longer. Undoubtedly it'll be a money sinker - a leggy & slightly shabby old bus isn't what most people would pay top dollar for - but I can see, now, what the bargists are on about.

Two final thoughts: (1) If I accelerate medium-hard, it can feel like a rear wheel is going over cats eyes. I have no idea what that might be.

(2) I've driven the car about 250 miles in 2 weeks. It had previously driven about 20 miles in 7 months! Bulb warning has gone off - I think this car wants to be used...

More update: car is going in on Tuesday for the PS line and good-used duo valve. With the tyres going on this weekend, the initial maintenance spend is heading towards 50% of the buy price, but then the car was very cheap for a multivalve 300 diesel. As long as I have a car with decent tyres & heating and that doesn't drain the fluid reservoir in one parking manoeuvre, I'm content with that.

Another job for the list: work out how to drop the rear seat backs (or free them off, if I'm doing it right).

And ponder the cold-cold start: ticking over at 500rpm is fine but, when it's cold, the car needs throttle just to sit at 500. I bet you can't just adjust a 90s diesel the same way my 60s Herald was done. Hmm.

New tyres! And a snapped wheel bolt.

But the underside looks - to a quick & uninformed glance - to be in reasonable nick.

Right. So.

Rear screen is cleaned, and a new Aerotwin wiper installed (previous wipers were Bosch, which I think is a good sign). Front screen has been cleaned, clayed & waxed - time will tell whether that was a good idea. Couldn't fit the front wiper, because the one supplied by ECP against the reg number isn't right for the hook end wiper arm (AP24U no good; AR24U looks like it's the right thing).

I've done a little bit of TCutting on the bonnet, which had the most lacquer damage. Not sure it's much improved, but I'll try again as and when. Plenty of work to be done on stone chips & small paintwork damage - I'll ignore the holed wing until the time comes to sort it.

Annoyingly, the front armrest snapped off at the bracket while I was cleaning the windscreen. Looks like either the entire armrest needs replacing, or (if it's removable), the swivel bracket itself. I like the armrest. Boo!

PS line - replaced.

Snapped wheel bolt - removed.

Duo valve - wrong one sent to garage, so innards removed & now putting out hot air. Ironically, I had one from a breaker arrive last night, but I decided not to bother taking it with me.

Squealing aux belt - not squealing (not sure how it's been fixed).

Wing mirror - decided to expire since Sunday. Apparently it'll need a new unit: does anyone know whether I can just replace the adjustment unit within the casing? It's an electric adjust, heated unit.

Armrest - being looked at now.

Bill - don't know yet!

Not yet! I've bunged some spray grease into the headrest slots - the garage couldn't move the headrest out or seat backs down either (but the boot trim release is now fixed) so more heavy-handedness will be needed.

Nice to have some heat in the car, and it seems to be pulling better. Might be wishful thinking, but the takeup seems more immediate.

Mirror is the next important thing. Armrest is a nice-to-have.

After I've swapped the front wiper for one that will fit - it was a bit awkward today.

Hopefully I'll get to kick the seats soon.

The shiny things have started to arrive... Can't do anything with them yet, but they're ready to go - nothing garish or non-OEMish; just some renewal-type bits on the visual front.

I've been running the car almost daily this week - 350 miles in, the car seems to be running better, although since the garage visit on Tuesday it seems to have lost the rev flare between changes, but is starting off in first. Not sure whether I think that tradeoff is worthwhile - I think (but haven't yet researched) that sounds like a disturbed vacuum line?

Anyway, hopefully tomorrow and the weekend will see some more incremental improvements made.

Good to know on the gearbox - thanks.

You mention something I've been looking back through your thread at, r129sl: sound. The bonnet pad on my car has seen better days and, although most of it is still fit for purpose, about a quarter of the pad is having performance anxiety. I think you've ended up with Dynamat Extreme on the bonnet, overlaid with a Febi pad: any good?

I managed a couple of things in my lunch break yesterday, despite the rain: new 2-piece aerial grommet collected from the dealer, door and boot seals treated with some gummi pflege (to hopefully reduce the instances of them freezing shut - I pulled off some under-bonnet seals when I opened that).

Most satisfyingly, I replaced the metal trim pieces of the door sill trims, using a kit from ebay. The trim on the trim was tatty at the least, and the driver's door trim had missing metal sections and curly pieces. The new kit came well-packed from Germany, cut to exactly the right sizes (two widths, two lengths) and after removing the old stuff & drying/cleaning the trims, ready to peel off the adhesive backing and stick. Metal even seems thicker than what was on there - a nice satisfying result for £30ish.

I'm now aiming to toddle outside, fit the aerial grommet, change wheel centre caps (I'm a tart), and give the rear seats some welly.

If you don't hear from me again, I'm stuck in the boot.

Good to know - thanks.

So, it's not been either an unmitigated success or disaster...

Wheel centre caps are on. They're shinier than the wheels (and the rest of the car!) and the blue ties in to the body colour.... but I'm not yet convinced.

Aerial grommet I decided not to do. The aerial isn't a Hirschmann one and has been put in at some stage (along with some non-standard wiring). Wasn't quite sure how to take it off, so decided not to fiddle with it just yet. I did put some silicone sealant around (under) the existing cracked grommet, as there has been water ingress from there. The window sill seems to be in decent condition on that side.

Rear seats have demonstrated that they're willing to fold. Headrests move better than they did... but I can't yet get them out. I should be pressing down on the black button, correct?

Then I took the spare wheel out. It's a Continental in good condition, but it's 15 years old, so I guess it'll need changing. There's a set of shorter wheel bolts in the spare wheel well, but they look rusty beyond usability, so will have to be replaced too.

Opening the spare wheel well demonstrated that that area seems to be in reasonable condition, but there was an old towel betwixt wheel & rear lap inner which was dripping wet. That's been chucked, and I couldn't specifically see where the water may be coming in. In my efforts to fault find, though, I removed and dropped the rear lamp. Arse. That's now both sides that need replacing.

Is there a cold start feature/circuit on these cars? Mine does not like starting up after being left overnight and needs throttle for about 3 mins before idling well enough to risk pulling away, but after that it's fine all day. Or is that likely to be a fuel line symptom?
