A Reckless V10 Purchase

[MrNoisy]

Great purchase op, watching with interest.

I too am on a hunt for something to tow my car trailer. Bizarrely I already have the trailer but the car to go on it and tow it are still slightly distant works in progress.

I was mega interested in these but then an article pushed me to the 4.2 TDI Q7. Then the man maths really started to kick in as I was comparing the fuel costs of a 24 mpg Derv to a S/C FFRR - I gave up at that point and refocussed on reality for a bit.

Good luck, keep the info coming.

Reading with interest.
Please keep the updates coming.

Just realised its you with the 2.7 S4 engined boxer off audisrs. Didn't realise you were a complete nut case! Good to see you making your way through the niggles. It's the fixing of the small stuff that really makes the difference I think on these types of projects.

Yeah, sorting out the little things makes a difference.

Water-cooled alternator?

I don't think so, Cayenne's have water cooled alternators and they don't have this seperate radiator. I'm thinking it might have something to do with the auxiliary heater

Don't let reality get in the way of a daft purchase, I didn't.

They’ll be utterly negligible.

I’d take the FFRR every time. I ran a S/C 4.2 for a few months and it never averaged less than 17mpg and didn’t need any maintenance.

I ran a 730d for 14 months and it averaged 24mpg, and had horrendous maintenance costs


My brother worked for a hotel chain and had a 56 plate Q7 as a company car a few years back and it was appalling, drivers door handle gave up on the inside and had to be opened from the outside, EML’s, electrical issues, it was a dog in comparison.

You say you bought this to tow?
And what have you bought to tow this?

You little toe-rag!

lololol

If you run one for more than a few months you'd definitely need to be spending out on maintenance

[carinaman]

Have a nice holiday. Good work sorting out the track rod end misalignment. I am enjoying this thread and the Boxster one.

[OldGermanHeaps]

well done you glorious lunatic. hope it works out well.
its one of these or a cayenne turbo for me when my peugeot goes pop but at the moment its unburstable.

It was in the family for 2.5 years, nothing horrendous in that time.

Had a BMW 4.4 Vogue as well for 5 years / 100k miles and that never had anything big either. Worst was an alternator failure.

A lot of people seem to think they’re horribly unreliable but that’s definitely not been my experience.

I’ve had Classics and a P38 as well and they were brilliant too.

Soon i'm starting a business where I'll need to tow 3.5 ton regularly so I wanted to get a tow car.

Does this then need a tachograph as you will be over 3.5T total weight?

This is something I wasn't aware of. I should be ok under the distance exemption.

I sold my previous daily driver and have started using the Touareg. It quickly became apparent that it loves limp mode. When I bought it the owner told me it did go into limp mode but it didn't do it on the test drive and it only happened once on the drive home. It would happen 3 or 4 times on my 10 mile drive to work (would need to stop and turn the engine off to clear the fault).

The fault is -

18360 - Turbocharger Control Module 1
P1952 - 000 - Defective - Intermittent


I believe the issue is due to carbon build up on variable geometry vanes in the turbo exhaust housing. I've not looked yet but my understanding is you can't get the turbo off or even the downpipe off with the engine in the car. I won't be pulling the engine on this car to replace or clean up the turbo, it's not worth my time or the effort. I've bought a couple of bottles of Wynns turbo vane cleaner, it's probably snake oil but it's worth a try. Just add it to the fuel tank and i've been giving it an Italian tune up every time I drive it. It does seem to be improving, the last time I drove it the power delivery felt different, more lively at low throttle so maybe it's done the trick but I won't hold my breath.

I love driving it, it's very smooth but the torque is crazy. With the air suspension on soft the front end lifts up and the back sinks down when you gun it. The torque makes it feel faster than it is but it does pick up speed quickly. The only criticism is the sound track, you can't tell it's a V10 from the engine sound, it just sounds like a big diesel engine (more like a lorry than a car). Maybe some K&N panel filters would improve that.

I replaced the radiator and kinked water hose, I also noticed the oil had been massively over filled, I sucked over 4 litres out of the sump.

[bolidemichael]

You seem quite sanguine about these issues, which is a fairly healthy approach to not getting dragged into big bills!

Are you certain that it was overfilled by four litres? It seems an awful lot. I've always doubted my reading of a dipstick, most likely because. I'm a dipstick sometimes when it comes to engineering. Perhaps it's for the best that my present car has an electronic reading.

[Escy]

The dipstick is a bit odd on these, when you pull out the dipstick it shows nothing on it at all, if you wait a few seconds, put it back in and pull it out again, it then shows the level. I think as the oil gets pumped around the engine, the level drops and the vacuum inside the dipstick tube stops it the level showing correctly when the oil level settles, bit odd but it must have something to do with the way they've routed the dipstick tube inside the engine. Someone has pulled out the dipstick, seen no oil and put a load in so it then registered oil the first time you pull out the dipstick.

[V8RX7]

I can't say whether it will work on a turbo, but I've used a DIY water injection to effectively steam clean cylinder heads and it works very well.

[Jakg]

I've also seen oven cleaner (Mr Muscle) used to clean the vanes on a turbo if you can remove a sensor and squirt it in near enough.

[bungz]

Does terracleaning work with turbos?

Failing that I fully expect you to break out the spanners and have the V10 swinging from a rope in the near future.

Common fix on VAG PD. I've used a fuel-tank turbo cleaning product on a PD100 engine and it took a couple of bottles but it fixed the limp issue. It's not snake oil in my limited experience.

I have heard of adding:

two stroke oil, veg oil and kerosene

to cure a range of ills

I've never heard any of them being used to fix anything.

However, several PD engine users believe that two stroke oil makes the engine run smoother. Veg oil has been used on a wide variety of suitable diesel engines to reduce cost, as has kerosene. But not heard them used to fix anything.

I've seen them all advocated for cleaning - particularly the last two regarding lines, pumps and injectors
