Sounds like MAF sensor fault. Disconnect the MAF and take it for a run, if it's running smoother then you need a new MAF. My S4 was doing the same 6 months ago and your symptoms sound the same.
Turns out my usual mechanic won't do it as apparently you need some sort of special spanner/tool for doing the belt that he doesn't have and it costs £150 so not worth his while buying it?? I'll try one of the Audi specialist in Glasgow and see what price they come up with. Thanks for the offer...
I've thought about second hand, I've been told I could get a great bike for a bargain but I really don't know what I'm looking for. More research required I think. With regards to weight of the bike I'm thinking of buying its MUCH lighter than the shed I've got just now!
Andrew, the Marin looks...
Only just getting into biking and have been using this old shed...
Nothing like the good bikes others have posted but I've had great fun on it so far and lost a bit of timber too! Going to buy a new bike in the new year, something a bit lighter and well more modern! Was thinking about...
Hi, I'm going to get a quote tomorrow for timing belt replacement but what other parts should be replaced at the same time? Water pump, thermostat etc?
Also what price should I expect? Itll be an independent not main dealer. I'm thinking roughly £600-£800 or am I in for a bigger shock than that...
It's a brand new genuine Bosch MAF but as I said I've left it plugged IN and drove it again and it's running perfectly now. It was just initially it was still rough but, all fine now.
Thanks for all the help :) I've driven the car a few times now since yesterday and it's running perfectly now, wonder if it just took the ecu a wee while to recalibrate itself?? Who knows, running fine no though :)
Hi guys, my 2000 S4 was down on power, running rough ect so took it to my mechanic (I suspected a faulty MAF) but he couldn't find anything wrong with it! So I unplugged the MAF and the car ran perfectly, that would suggest goosed MAF. I've just installed the new MAF and now the cars power is...
Sorted! Well, almost. I unplugged the MAF and took it for a drive and its running perfect, even the whine from the clutch is almost completely gone :) Also the car seems super rapid now so perhaps the MAF was playing up before it broke completely and I never even realised. Anyway new MAF should...
Evening chaps, so got a bit of an issue with my S4. It passed its MOT with no advisories :) about 3 weeks ago so got a mini service done at same time too, fast forward a week and I'm joining the motorway, put the foot down and something didn't feel right. It wouldn't boost as hard as it normally...
As per title, looking for a recommendation for a place in or around Glasgow that I can speak to regarding remapping my B5 S4. I've seen a few advertised but would prefer a recommendation from someone on here. I've got a few questions and don't want some cowboy just saying yes to everything just...
Just renewed my policy with Privilege today on my S4 for £212. I'm 34, 9 years no claims and my wife's on the policy as well. I'm delighted with the price.
