Audi S4 B5 Avant
Hi,
My 2.7 S4 has been fine since I bought it, however, recently it's been revving 3 or 4 times, quite high and very quickly, just blips when you start the car up. Haven't had any throttle depressed when starting.
Also, sometimes the idle is a little lumpy, but it's not that bad, not bad enough to be a problem, it's the strange revs when starting that annoy me.
Any ideas on what it could be? I'm assuming it's the MAF metre, I found a price on the RS4 MAF metre, but not the S4 one - what's the price on this? I don't want to change the airbox and everything right now, what with xmas coming up etc!
Also, recently it only seems to average around 18mpg, I used to get around 24mpg ish with similar driving - just running to a from work. It seems to drive ok, but it can hesitate if you put your foot down at low revs, say around 2k.
Thanks,
Dan
