Still too expensive though, I got my BMW done for less and thats a much more stressed engine. There was a post on this a month or so back, someone on here has had it done (sorry can't remember who).

And can the after-market chip tuners offer alternatives?

As for a re-map; well I have taken the plunge and I can say that this has exaggerated the problem and not cured it as you may be hoping for
who did thr remap for you
at stealth when we use the roling road these problems show up and we change the map to suit the car that is why it is better to do a custom map for your car as all cars are not the same

Darren C said:Hi shoestring7,
Interested to hear that you have had a fuel contamination diagnosis. I am not wishing to high jack this 'fsi' thread, but my TDI 75 is behaving similar to your fsi it would appear. Under full throttle the power seems to 'cut in and out', there is seldom constant fueling. Does this sound similar to your symptoms? If so, what did Audi do, flush the system? I take it from your post that this has made little or no difference, however!!
Mine goes in to the dealer this week for a variable service and I have asked for a fuel filter change at the same time, though I doubt it will resolve the issue though.
As for a re-map; well I have taken the plunge and I can say that this has exaggerated the problem and not cured it as you may be hoping for. (Though to be fair it may work for your fsi).
Cheers,
Darren
Shoestring7 said:Darren,
Mine is a 1.6 petrol so I'm not sure of the system in a Tdi is the same. As I understand it there's an activated charcoal in the fuel system to trap vapours. This had broken up into a sludge, and was blocking filters and pumps. The eventula fix was to dismantle and clean the fule system and fit a new pump - they had two goes at this before the symptoms were reduced. Currently its back again, this time they appear to be looking at the ECU map.

seriously though any remap will not solve a problem that isn't map related, ie if there is a sensor or component problem it can't resolve it, it can in the case of a FSI get round the drivability issues built into the software by VAG in the first instance to achieve the required emissions figure, they delibrately run things lean to achieve this which results in poorer drivability than could otherwise be achieved.
