Slow acceleration - Diverter valve???
Got a quick query...
I just had my diverter valve replaced at Audi. On the drive home the car seemed fine (all motorway). But when I drove it the following day the acceleration seemed quite 'flat'. It seems ok up to 3k RPM anything over that it just seems flat, as if I'm not getting as much boost, I wouldn't say it's 'slow' but it certainly isn't as punchy as before.
The car is completely standard, and they replaced the valve for a standard one (not Forge etc).
Could the lack of acceleration be down to a faulty valve?
Unfortunately I don't have VAG COM, and I can't get to the garage for a while, but would like to diagnose the issue sooner rather than later.
Any help or advice would be appreciated.
