brand new leon FR TDi with only 3000 miles done
Driving down the M4 on Wednesday, put my foot down and nothing - no power - then a second later revs went to 6K and stayed there!!!!!!!
Had to switch ignition off and drift to hard shoulder - not nice.
Nice man in yellow van came out - started her up and same thing - revs to max and stayed there - towed to dealer - hope to here fri whats caused it - front runner is oil level - they say they drained 8.5 litres out and it should have 3.5!!!! I have not touched the oil so that is from factory.
Will let u know outcome.

8.5L? surely the level check would be in the PDI - have you checked the oil level?

also, 3.5L is a bit low....

more likely a throttle pot is throwing a wobbler i'd have thought.

We've had an Audi 170 at work do EXACTLY the same.

It seems that the engine builders have put the cylinder head on wrongly (originally thought to be a seal in the turbo that was faulty), this caused diesel to seep into the oil, and the oil to be burnt in the engine (hence the high revving - it getting its own supply of fuel not regulated by the throttle.

Just got delivered back today, along with a total cost of just over £10k for a new engine. (all under warranty) - this Audi had 1,500 miles on it.

Assuming it is the same, your be looking at 2 - 3 week fix.


/edit to add - if you need contact details of dealership that fixed this one, let me know via PM. (I'm certain judging by the 8.5 litres of oil, that this will be the same problem (diesel leaked into the oil) )

10K for a new engine? Seriously? wow..

You know Audi :shrug:

Get it in, strip some components, strip some more, identify fault, decide what to do, strip all of engine from car, order replacement, ship replacement in.

Install new engine, including replacing every pipe / component that may have been affected by the diesel/oil in the wrong areas.

add on mechanics time to do this (i.e. lots!).

+ vat

Present to customer to sign to confirm work is done, before shipping invoice to Audi UK for payment. :)

blimey tam, thats shocking! putting the cylinder head on wrong????? MAJOR manufacturing fault!

Always assumed it was done by robots, but something/someone f**ked up somewhere :lol::lol:

Wouldn't surprise me if a whole batch are wrong somewhere.

saw a piaggio engined daihatsu hijet do it once even pegged the thing against a wall to try and stall it but wouldn't stop

lasted nearly 20 mins before it eventually popped much to the fire brigade's amusement as they turned up to see what all the smoke was pouring out of the now foggy workshop

1st and only time i'll ever see a cheer for a noddy van :):)

This happened to a customer with a brand new A3. After some complaints he got his money back :(. I think the car was bought very late last year. Think it may be worth checking the oil a little more often, that is if it builds up slowly.

Scarily We've also had a new Audi do this at work. It was an A6 1.9TDi. Revving out of control due to it burning the oil. Trouble is the bloke was on an A road and it nearly took him staight over the middle of a roundabout!

Blimey that is extraudenry (SP) doesnt bare thinking of with a diesel to check the oil as mine never used to use hardly any. Although at least you know the new 16v dervs will rev to 6k ;) would it not have been an idea to select nutral and drift to the hard shoulder? rather than turn the car off? as you'd surely lose the brakes and steering?

you are bang on the money TAM - dealer reports the 8.5 litres is due to diesel in the oil -this is what caused the over revving - luckily I was able to switch off the engine.
Bad news is they are saying it needs a new "thruster pump" and is on back order until 13th july!!! Decision on monday whether part is avail on emergency order - if no then I am considering trying for a full refund!

Thought i would be.... i'm also expecting to see more posts from other owners who this has happened to. (might be worth postings in the audi and skoda forums so they are up to date.


IMHO - I would reject the car completely until they fit a BRAND NEW engine.

You have absolutely no idea what damage may have been done to the engine while it ran on all sorts of oil/diesel. Might also be worth them replacing the DPF too.


/edit to add, have the actually prooved it was the thruster pump, or is that their "guess" at whats wrong?

to befair if it happened on my car, id let her rev the shite out of her and demand a new one, I wouldn't be happy with a repair on an engine that did that!

Also - put in a very serious ticking from a solicitor about it nearly causing an accident, see what the result is then compensation wise..

on dpf'd systems the oil level does rise seen some go up by 2 litres and caused by diesel dilution, mazda 5's with dpf's are terrible for this

belive me , when this engine revs to 6K and stays there you'll want to turn it off!

I think thats their guess, although how can I argue? i'm no expert.

just because this has happened (and other manufacturers have had similar issues) doesnt mean it is ok.

where exactly does the fuel get into the system? does this mean that all the fuel is not being burnt and is wiped away adding to the oil? if the oil level does rise on dpf cars is it only a matter of time before all dpf cars essentially internally combust?

if i had one of these cars i'd be concerned to say the least.
