Hello fellow A3 3.2 drivers,

Just a heads up on a problem I had with the car recently, should you encounter the same thing.

The engine management light has come on a few times recently, often in conjunction with a fluctuating idle or stalling. Initially a faulty mass air flow meter was diagnosed, then a ham fisted technician was diagnosed (he bent the pins on it trying to fit it) and all was well for a time.

However the problem returned and was diagnosed this time as needing new lambda probes, front and rear.

Despite fitting both new probes, the car would not run properly and the dealer had to refer the problem to Germany as they were stuck. It turns out that the software for the probes has changed and once they uploaded the new software all was well.

So if you have new probes fitted and they don't work that may very well be why.

Happy motoring. smile

Sounds like they were covering up for their own cock up, more likely the probes have changed design and they didn't noticed an ECU update was required...

read through that thread and there are alot of people who have varying problems and not all of them are cured by the same thing. mk4 golf R32s had that problem and they changed the software and it went away.

where did you get the software updated? job for audi? and what did it cost?

Main dealer. The new software seems to have done the trick as it's been running faultlessly since then. Parts and labour for two lambda probes was £420. Fortunately I wasn't charged for diagnostic time as they'd already spent enough time trying to fix it on previous occasions.

I bought the car from them and have had it serviced/repaired there ever since. I've had a few problems with it over the years (you know it's never a good thing when you're on first name terms with the service advisor hehe) and the software update was necessary to get the new probes to work, so I suppose it's either viewed as an inclusive or necessary part of the fitting, or they've shown goodwill.

Either way, whilst the car gives me trouble from time to time, the dealer (Caffyns Audi in Brighton) has been very good.
