I am very challenged - although I do try google to resolve my ignorance -
when it comes to cars and how they work.
I have received my A6 back from the dealer as it was asking for oil, from
full, after 500 miles cruising on the motorway at a steady 80/85 mph.
Still under warranty, 3.2 FSI V6, nearly 3 yrs old, 40K on the clock and
fully serviced they have replaced and removed all plugs, fitted a new valve
stem and seal on number 5 - whatever that means.
Do you seasoned Audi guys think this will resolve the issue.
BYW there was no visible oil leakage.
Thanks in advance
If there really was no oil leakage, then I can't think of any other place
for so much oiul to go but out the tailpipe meaning that it was getting into
the combustion chambers and being burned. Getting past a valve seal is one
way for that to happen. However, I would think that with your oil
consumption - I assume 500 m/qt - that you would have been noticing some
tell tale bluish smoke out of the exhaust. Was that the case?
If valve stem has been replaced, that means a valve has been replaced as the
stem is forged to the head of the valve. If they suspect that valve stem/
guide clearance is the problem, as it would appear from the components they
have replaced in an attempt to cure the problem, the actual problem, they
suspect, may be wear in the valve guide. It used to be possible to press out
an old guide and press in a new one into the cylinder head. If they really
have changed a valve then they must have removed the cylinder head, in which
case why didn't they change the guide at the same time to totally kill
excessive clearance between the two as a problem. On the other hand a valve
seal fits on the camshaft end of the valve and can be changed without
removal of the cylinder head. Quick fix? Has the valve "stem" been changed?
If you have been consuming excessive amounts of oil that are going down the
exhaust pipe, I would also be mentioning to your stealer the effect of this
upon the catalytic converter, they don't like swallowing too many of the
additives contained in oil, the catalyst becomes "plated" and unable to
perform it's designed function.
There are only a few ways an engine can lose oil.
Past the piston rings.
Into the coolant circuit.
Down the valve guides.
External oil leaks.
It shouldn't be beyond the wit of your stealer to determine which of these
is the case - and then to cure it.
The trick is to get them to concentrate long enough on your problem to
properly address it, they would far sooner be selling new cars.
Kick ass, they're just spinning time until the end of the warranty!
Well the oil issue seems to be resolved, however, on a round trip to
Manchester on the first day of picking it up (had been 10 days with the
garage) it broke down - a worn coil.......
So that's it, is now is fixed and sold.
I am going to the dark side - BMW

I'm here because I lemon-lawed my 2005 Honda Accord Hybrid. It averaged
maybe 6 hours a month in dealership labor plus it had the occasional
replacement of a major engine system. Can you imagine paying for that
when the warranty runs out? I couldn't have even sold it because any
decent test drive would have brought up OBD codes that would fail a smog
check. It scared the crap out of me. Sometimes you have to get rid of
Am hearing you, sometimes you just loose faith with your wheels and have no
confidence in making the local shops let alone a long haul.

In all fairness and stating the obvious there are millions of happy Audi
drivers that can rightly sing Audi praise from the roof top - I have just
been unlucky and currently have a bad taste.
From faulty boot locks, intermittent starting problems, oil and EPM issues
it seems my second home home has been the dealership and I or the car have
been a Jonah over the last nine months :)
Never owned a beamer, like the X5 and think the change will flip my luck.

I use a school book to keep a record of events such as putting in
oil: the date, how many miles done and about how much etc.
The replies you have had seem to cover most of what may be said.
You could take the car to an independant mechanic who may be able to
see if the cylinder head has been removed. They may not make any
charge for this as it could take but a few minutes. Ask, some are
