The car above seems to be sold, but it definitely got me-a-thinking................How much would it have cost to have put right?

Your thoughts please?

Te guy who is selling that car has thread somewhere about it , think it's in the speed plod and law forum

The previous owner said 15ish hours of Labour and only certain garages could deal with them.

why would turbo failure lead to the engine seizing up?

good question, I'd like to hear the answer to this...

Could have ruptured the oil feed or something, thus pumping all the oil out of the sump pretty quickly.

[deadalfa]

Or a bearing could have failed causing compressor wheel/housing contact, the resulting debris either holding a valve open or picking up on the bore.

Or a wastegate component could have failed, leading to excessive boost pressure and rather toasty pistons.

Or something else.

Thanks for the link, that was an interesting read.

But in terms of cost/ time, I gleaned only that 15 hours were needed to diagnose and take the engine out. That amounts to £1500 + VAT at the main dealer.

How much to get the car back on the road?

Oil seals blow in the turbo, turbo then forces oil round the induction system, where it gets ignited in the engine with ease because it's a diesel, car then runs itself out of oil due to poor routine maintenance (not checking your oil level at least once a week) and therefore starves the bearings and pistons of oil.

VW engines, petrol and diesel like to do this for a pastime.

It's times like this, that those sorts of folks who know their oats and aren't afraid to get stuck in are laughing.

I suspect we'll see more and more of this as these massive expensive luxury cars slip out of warranty and things go wrong on them, whilst unemployment goes up and fuel prices continue to climb!

Got nothing to do with poor maintenance. The engine runs on engine oil directly from the turbo, no diesel pump, no rev limiter, engine eats itself. If you are quick & have your wits about you, you can stall the engine (I've done this) or starve it of air if it's an automatic (I've never done this) & avoid catastrophic engine failure.

I had that car before I sold it on to that chap. Bloody awesome barge - really loved it.

Sorry to hear something went wrong with it and hopefully things worked out (relatively) well in the end.

I had around £6k of engine trouble on a Passat. So the Phaeton will only cost more. VW are pure tat - and thats from the mechanic.

That's when the seals let go completely though. They can go slowly, and just drain the sump of oil over a time.

Turbo failure on the V10 is very well known on the VW forums iirc.

[Busa_Rush]

53,000 miles and only just 2000 miles passed its third service ? I know VW were pioneers of long service intervals but that's too long in my view for a diesel to go without a service. Is there an interim oil change then a service ? I'd change the oil at 10,000 miles maximum in a diesel.

Argh yes, I see what you are saying now. I thought total failure was what you were talking about. Carry on. I had a turbo impeller shaft totally snap once, that was fun.

Yup, Engine and Transmission OUT on a Touareg. And given that, advisable to have BOTH turbos done at the same time. Probably the same on a Phaeton.

The owner can have his/her oil changed whenever they want. They don't HAVE to wait till the service light goes "bing"

• We know that* but I suspect most owners would only do the minimum stipulated in the schedule.
