Happening in a FSI engine near you...now!

But have you seen the crap they have to put in their cars for petrol? It is truly awful, no wonder their engines are as bad.

Remember that in the US they quote the average of the MON & RON values for "gasoline" but in Europe we quote the RON value for petrol.

The difference between MON and RON is about 10, so US 93 octane gasoline is equivalent to UK 98 octane petrol...

Hi All,

I'm a new member and bought my B7 RS4 (a 56 plate with 34k on the clock) just six months ago.

The car's been everything I'd hoped for the 1st 3 months - then came my first Engine Managment Light (EML). I took it straight to my local Audi dealer (Hitchin) who diagnosed a fuel mapping irregularity but couldn't find any fault. 3 months, and 3 more trips to Audi for diagnostics, later and they tell me they still don't know what's wrong but the next step in the "guided fault finding" is to check the injectors for leaks and, if none found, to send the injectors away for testing - fair enough.

Next day they call me in to show me their findings & my inlet is seriously coked up (MUCH worse than any of the pictures I've seen on this thread)!! They claim they've no idea why this has happened but the only Audi approved way forward is a full, engine out, strip & de-coke with new valves, injectors & gaskets (and I'll be looking at about £10k for them to do it)!!!!

So I did a bit of digging and found that that this isn't exactly an uncommon problem so escalated this to Audi UK who couldn't really have been any less helpful if they'd tried. My suggestion that this is a common problem and possibly a design flaw - "we don't know of any other RS4s with this problem" and "the problem with your car is most likely the result of the use of poor quality fuel and a failure to drive the vehicle as it was intended". Furthermore, I "have to expect a certain amount of financial commitment when buying a car such as this" and as I "didn't purchase the vehicle from within the Audi network" and I "haven't demonstrated any brand loyalty" the best they can do is to make a "good will" contribution of 10% if I decide to proceed with the decoke. This is a "full & final offer" and I've got 7 days to accept it or the offer will lapse.

Fair play to the local dealer who have said that I won't need new injectors and that they'll match Audi UK's 10% - but I'll still be looking at >£4k for the work to be done!! Frankly, I thought that Audi UK's response sucked - If that's how they treat their customers I can't see them engendering any brand loyalty.

So, question time - Is engine out REALLY the only way forward? Surely the inlet valves & chambers can be cleaned (manually/ultrasonically/chemically) in situ?

Any thoughts would be very much appreciated.

Take it to MRC after Hitchin put it back together again and get a proper diagnostic and quote.

audi dont want to know, cars are 5/6years old now

[Reynard-Dargent]

Take it to MRC afer Hitchin put it together and get a proper diagnostic and quote

That'd be MRC in Banbury then? It's a little waya away from me but not so far as to be totally impractical. Many thanks for the tip though, always good to get tried and tested recommendations from users with experience - That's one of the reasons I joined the forum

For a carbon clean up Mrc have mastered it, only other person I know who does it is Martin at unit 20 in the Wirral

+ Revolution but they are a little way away from Hitchin in Newcastle

[adsgreen]

May be a little way but for 4k + probably worth it.
