    I have a 2003 VW Passat 1.8t with a cat back exhaust system and previous owner removed the catalytic converter. It starts up and idles good no misfires but when I'm accelerating building boost the engine starts too surge and rev up and down like the boost controller is pulsing the waste gate...

    Hi everyone. First post here. Recently bought my first VW. A B6 2007 2.0 Tdi Passat. It randomly drops revs, no dash lights, can happen in any gear (tends to stall the vehicle if in 1st). Changed the fuel filter today and added redox diesel cleaner. No success, went out for a blast and it cut...

    Hey, I have a 2006 2.0T, have recently replaced DV, PCV, timing belt, HPFP, camshaft. Now, under hard acceleration but low rpms, when the boost comes on, there is a 1/2 second period where rpms drop with some loss of power. It still pulls decently strong though. Mostly occurs between 2000-3000...

    Hello. I have 99' 1.6 b5 and a few days ago I've noticed that when engine is cold my acceleration is stucking. I tried to check acceleration cable, but it seems that it's working properly. Also, when I'm accelerating very shortly, to make revs go high and down straight away, my revs are going...

    hi just got a 98 passat estate the other day and the only prob I have so far is that the revs rise and fall when ticking over. This causes it to stall while parking and manouvering at slow speed. It runs well apart from that and I have done 600 miles + in the past 3 days with any other running...

    Don't know if I'm in the right place but I have a 1999 passat (2.0) that starts fine but dies to an idle as soon as it is revved up - it sat for a few months and ran fine before that. Changed MAF but didn't work - any ideas?
  13. Volkswagen Passat B5 Discussion
    hello guys, this is an 03 1.8T, at exactly between 1000 and 2000 revs and not a single rev below or above this interval, you can see the rev pointer fluctuating within about 100 rev range, you can also feel and hear the the engine waving as this happens. It happens only when the engine is at...

    Hi, My 2000, 1.8 passat's revs jump from 500 to 1500 at idle and occasionally drop for a second or two on the motorway, the airflow regulator is currently unplugged under the bonnet the reason being that the car starts but cuts out immediately if this is plugged in. what do you suggest the...

    My car has started minor hesitation under mild acceleration. Having driven it a couple of times since I can now narrow down the times this happens so was wondering if anyone else has experienced the same (a) car drives fine until it is up to normal operating temperature - no hesitation at all...

    when i rev the engine in neutral the revs seems to take a while to come down. a couple seconds. most cars i've had, all of them NON TURBO, seems to go straight down, but the 1.8T seems to deRev slower. does that make sense?
