Motor change under warranty

[MikeD]

Well, after many months Audi have agreed to change my motor for a 0Km new unit at no cost!
The original complaint was lack of power and not running smoothly.
The official line for the change is due to "Oil consumption in cly8".
The man from Audi Germany arrived and took the car for a test run, got out and said in his report, change the motor.
At which time my country’s Audi goes, "wait, wait we need to check as well and see if we are going to pay 100% or if we only pay a %" so they then sent their man over, he looked inside the motor and then made his report of cl8 consuming oil, when asked if the valve stem’s were clean his answer was, "Yes", but as he only took out the spark plugs to use his scope to inspect the condition of the motor and not the intake manifolds I was very impressed by the fact that he was able to see the valve stem from there, when challenged he went a little red .........why do the assume that we have no idea and treat us as if we are brain dead, the fact that we were able to buy these cars should indicate that we are not totally stupid !! sorry, rant over.
So, it can be done but you need the help of an Audi dealer who can see both sides and is willing to go that extra step, I am very lucky to have just such a dealer here.
I know I am not the first and I hope not the last, but from what I have found Audi will, in the end, do the right thing and sort the motor even if it takes a complete replacement to achieve it.

Glad you got it sorted, and 100% agree with you Audi will do the right thing. It would be good to see what a new engine (after careful running in) produces at the dyno.

[MikeD]

Wish we had a dyno close by, but no such luck. Also want to see if the oil temp is lower.

[Sims]

.. Also want to see if the oil temp is lower.

Or higher?

[MikeD]

Oh I hope not, 125 C is too high already.

[Sims]

Oh I hope not, 125 C is too high already.

In Spain, of course

A guy in Oz also had engine issues, though not the same. They too have high temperatures.

MikeD,

I remember back in 08 thinking your oil temps were super high although running the car in Spain I can understand that...

Not sure what the problem with your car was in the end but would Audi say if it was related to the high temps it was running?

Just curious.

[MikeD]

The company line was " We are going to change the motor NOT because of loss in performance or the high oil temps, but due to oil consumption in Cl8" basically carbon built up on valve stems, then dropped into Cl8 and scratched the lining, they also said that the new unit may be better or may be worse on the temps and/or power.
So, into dealer today, out next week, run it in, then we can find out whats what.

[ArthurPE]

so they inspected the motor and found no deposits
when asked if the valve stem’s were clean his answer was, "Yes"
but you conclude he's lying?

Audi said carbon scratched the cylinders or you did?
The company line was " We are going to change the motor NOT because of loss in performance or the high oil temps, but due to oil consumption in Cl8"
and
The official line for the change is due to "Oil consumption in cly8"
I assume you added the stuff after the quotes about carbon and such...

you're in Spain correct?
I'll be forwarding this to Audi for their side of the story

[MikeD]

Hi ya ArthurPE.
The info from Audi was " We are not changing the unit due to lack of power or high oil temps but due to Oil consumption in cylinder 8â€

[2manytoys]

oh my god Arthur, why are you so interested in this, and challenge everyone, it's pathetic.

To the OP, that's an interesting story. I'm going through the same thing. "Wrong Oil" is Audi's claim (but it's always had the correct oil).

Here are my bore (my thought, and another mechanic, is the scratches were caused by carbon).

[MikeD]

ArthurPE : If you would like more info about this possible problem please try this search on the internet "4.2 fsi valve deposits"

2manytoys : sorry to ask but what is OP

[P_G]

Thanks for the info. Mike. Regarding blow back / blow by, I think I understand your theory and would therfeore be interested on your take on the information available from those who have installed catch cans into their system who thereafter report that the amount collected in the can is tantamount to a couple of ml after thousands of miles which would tend to suggest that blowby is not as prevalent as perhaps suggested?

[MikeD]

I am no expert in the fine details but the blow back will be dependent on a wide number of factors as well as the amount of any deposits. Here in Spain we have some of the worst fuel I have seen, it will surely provoke more deposits.

OP = Original Poster, that's you Mike

I read this "a catch can collects next to no oil" all the time. PG, can you point me to the list that shows the people who have tried it. I'm curious, as my Subaru race car (new engine, built with careful clearences and run in on the Dyno) catches about 250ml every couple of race meets. I know it's a different story, as the race car is run hard, but even if I were to say a race meet is 10 times harder on the engine, that's probably about 250ml every 2000-3000km. Anyway, just a comparision.
