TFSI oil consumption fault - affected models?

I've got an Ecoboost Ford and so does my mother, neither engine has used a drop in 50k combined.

I forgot to add earlier that our 2015 focus st requires a topup of approx 1ltr every 6000 miles.

Surely you just change the oil on most cars or have the germans reinvented the total loss systems that veteran cars and motorcycles used ????, emperor's new VAG anyone

The problem these days is that people increasingly treat cars like white goods - they expect to be able to take the car to a dealer once a year and do absolutely nothing else to it, even the idea of checking tyre pressures or topping up washer fluid is alien to most drivers.

In the hands of someone who's likely to just carry on driving if the oil pressure light comes on, needing to top up the oil every three months becomes significantly more of a concern.

I agree, when you add the fact they also have no mechanical sympathy and drive a car hard from cold, you can understand why oil consumption occurs. The rise of leasing makes it worse as those early months dictate how the engine beds in, and lease drivers don't care about long term reliability.

I own and run a 2.0 litre vw tfsi, with negligible oil consumption between services over 4 years.

Ironically in the past I remember expecting a small amount of oil consumption because it was thought that meant the lubricating oil was getting everywhere.

Bringing up an old thread, I know - but better than starting a new one.

My A5 2.0 tfsi has been diagnosed as having this issue. However, Audi refuse to do the work without £1000 contributed by me as I can't find my service history for the past 20k miles (FASH before that). I figured that given it should have been done by them at some point previously, they should be doing it now.

What should I do? Any ways I can twist their arm a bit? This car would be a keeper, I've had it for over a year, but I'm very quickly losing interest and it's now due an engine and gearbox service, topped off with a big rebuild bill.

Can't you contact the garage that's been servicing it and ask for reprints of the evidence? Probably not much you can do if you can't prove it's been serviced.

I have a 2010 Audi A3 1.8 TFSI with this oil problem. It’s undergone (and failed) an oil consumption test. Now Audi have said they’ll contribute 90% of the cost of fixing this problem leaving me with a bill of approx £600. Seems a well known problem if they’re paying almost £6k themselves.

I owned a 09 model A3 1.8 tfsi on a 58 plate.

Car was on about 80k when I bought it, I gave it a full service, plugs etc... I then thrashed the tits off it from cold for around 6k miles. It did not use one drop of oil during my ownership.

So they don't all have problems. It's mainly the 2 litre, early versions.

Did you have to meet any conditions? I.e. Full Audi Service history present?

I’ve just purchased a 2009 A4 1.8t saloon it had 43500 miles on it I’ve done 2500 miles in the last 3 months and have used 3 litres of oil !! It has full Audi history except for the last service that was done by the garage before I purchased it. I’m not impressed

I think the only unaffected model is the 3.0TFSI unit in the S4/S5/A6/A7/Q5/Q7. There is oil burn under exceptional circumstances due to the PCV, but that is about it. Replacement of the affected parts on the engine isn't an engine teardown requirement, believe it is a straightforward fix. The 2.0T was affected badly by it.

Edit: oil burn, not fuel burn

Book it in with Audi for an oil consumption test. When it inevitably does fail, see what they say. Quite a lot of people have had their engines rebuilt free of charge and some have had to pay a contribution towards the sum.

I'd be blown away if they were willing to contribute to repairs on a 9 year old car that's strayed out of their network.

Nope, my S5 which had that engine suffered from oil consumption too. It was still under warranty so Audi did the oil consumption test, agreed it was above tolerance limits and changed some bits which fixed it. Wasn't an engine rebuild job so it may be a different issue to the one in the 2.0T but it's definitely there in that engine too.

As I said above, I personally think it becomes unacceptable when the oil has to be topped up between services - that either means the service schedule is too sparse of the oil consumption is too high. Max to min on a 2.0 TFSI is about 1 litre, so with VW's stated tolerances, their service interval should be no more than 2000km.

I have a 58 year-old Jaguar Mk2, 3.4L. It had new pistons, 30 years ago and uses about a pint every 600-700 miles. That’s less than these stated tolerances and the XK engine had a reputation for high oil consumption.

Wouldn’t say my 2008 BMW E93 325i is recent, but it has the N53 DI engine and didn’t use any measurable amount in the 4 months and 4000 miles use in my hands.

Does anyone know if the 2.0 TSI engine in the mk6 gti was affected by this? Engine code CCZB
