Carparts4less is the best place for a coil, it'll be Bosch. If you want a gen one your local dealer is your best bet. You'll lose quite a bit of coolant with a thermostat change, G48 is the type.

Nice car, never been out in a 130i, sure they are very capable cars!

Does seem to be the case, my £350 330i manual touring has had less faults I reckon and its on 178k now! Rust will win on mine though, its everywhere.

My E46 330i automatic touring has also been perfect in the year or so I've had it bar the rear parking sensors. Mine's only on 88k though and absolutely rust free.

Yes, yes, ok, rub it in!

To be fair, this is the first thing in 5000 miles that has stopped me driving it. There's a few niggles but it is a 14 year old car with 150k on it!

I swapped the coil pack to cylinder 1 and the fault moved there, although interestingly there were a couple of misfire codes on cylinder 3 before I reset it.

The other (thermostat related) code came back after every reset - what does it mean in real terms? Is it OK to drive? It must be opening and closing as the engine warms up perfectly normally...

Cylinder 1 has a Bosch coil pack but all the others are the black Bremi ones - I thought these were the crap ones on earlier cars that tend to fail? I had assumed I would have Bosch ones all round... Is the mixture a bad thing?

A mix of coil packs doesn't really matter as long as they are a decent brand. Re what the thermostat code actually means, can't really remember of the top of my head. Apart from it's broken! On these engines they normally take longer to warm up when the thermos fails.

I will admit I did feel sorry for you when everyone started putting the boot in! It's not really what you need when the car is giving you a little grief.

Good banter I suppose though and you've took it in good spirits.

Well the coil pack is on order.

Just had a quick look and the stat looks like an arse of a job including removing fan. I need the car for a family holiday in a couple of weeks and I've got a lot on so I may just book it in for it along with the oil filter housing gasket. Also noticed that a belt down the front of the engine looks a bloody state. Surprised they didn't pick it up on the inspection 2...

You have two aux belts, one for air con, one water pump/alternator.

Aha, it was the left hand one which I think is the a/c belt rather than the serpentine one. Although I'm guessing that will be just bad. Looks like something else to be done with the fans out...

A/c belt can be done from underneath with fan on. Main belt needs the fan off.

(PS- 150k miles, yes I've had a few problems but easy come easy go. Not many manual 330 touring sports around to be picky with)
You are so right on the picky aspect!

My nephew drove my 325ti Sport Compact a couple of years ago and realised he needed one in his life! I found him a facelift with sunroof, OK only an SE but a 6 speed.

Then his OH became expectant, so he needed something a bit bigger all of a sudden! spermbanghead

Found him a 54 plate 325i Sport Touring in Imola Red - but it was a 5 speed? It seems the facelift only gave the diseasels, 325 Compacts and 330s a 6 speed box. So a 6 speed 330i Touring is heading towards the rocking horse doodah!

I bought my 325ti as a vaguely practical car, but if I could find a good 330i Touring I'd jump on it as I think the Touring is the 2nd best looking E46 (after the Coupe, but that isn't practical). laugh

Gratuitous photo of his Imola Touring and my Compact!

Not really remotely comparable, in truth. OP's is a rare car, and prices tend to be strong even for high mileage examples - I don't personally think these faults are in any way dreadful for a car of its age/mileage.
No personal offence, but yours is a rusty non-Sport heap that looks like it's been used as a farm runabout.

Mechanicals are the same except the 6 speed box I thought. The sport bit wouldnt effect the problems which he has had as its just a few cosmetic bits/lower springs I believe. Was just making a comment on that hes not having luck with the mechanicals, was not intended as a dig at him.

If it wasnt before me, ive certainly gone some way to make it into one, drifts fantastically in the field. The rusty shed will still get to 155 and maintain a 130mph cruise all day long so mechanically it seems spot on. Shame the fuel tank isnt much bigger at those speeds though.

I wouldn't say any of the faults have been particularly egregious, most of the faff seems to have been with the boot lid hinge. Didn't your 330i have all new suspension fitted also? Arguably I'd be more concerned about the rust than about a coilpack failure or the likes.

For the record, both of my E46s have been reliable cars. The 328 did jettison a caliper carrier bolt yesterday, so has a wheel bolt holding that in place to get me home.

Thanks, yes the tailgate hinge would have been fine (if floppy) if I'd left it alone, and it's all fixed now.

Original suspension as far as I can tell but it really does feel as tight as a drum. Got a few bushes that need replacement but happy with the ride & handling generally.

The car is a bit tatty exterior wise, but honest. There are a couple of spots of rust that I intend to get looked at before they worse, and there are some bits of lacquer peel - by far the worst is the drives side wing, and the bumper. I have been on the look out for a wing but it's a rare colour so I will probably get the wing and bumper blown over at the same time as I get the rust sorted. I want to get the mechanicals sorted first though.

I love the car though, must have been a great all-rounder when new. I wish they had done an M-version. I think a supercharger would have been great too, just to add a little mid-range!

AC Schnitzer did do a supercharger kit for the E46, the ACS3 and few U.K. Cars were converted. I tried to buy one about 10 years ago but we couldn't agree on the price.

Bosch coil turned up and duly fitted - looks different from the two types already in there (one of them Bosch), no silver bit, all black plastic. Spark plug end looks different. Bosch printed on it and in a Bosch box though. Fitted though, and no code or engine light after 15 mins running so seems fixed and engine running smoothly.

Funnily enough, as I had the code reader plugged in I checked the live data stream while the engine ran up to temp. Engine temp rose as expected and when it hit 94 or so suddenly the rad temp started to increase from ambient so I'm going to infer from that that the thermostat is working. I guess there could be an open circuit across the contacts on it or something that doesn't affect it's mechanical function but the ECU doesn't like it and is throwing a code...

Thanks to all especially helix for the advice.

Another thing to note is that these thermostats are heated and electric. If you floor it, the car will open the thermostat. Could be an issue with that.

I can't understand why you,didn't just change all 6, if one goes they all start going. I made that mistake a couple of years ago and I've just had all of them replaced on my 325i E91
