intermittent hesitaion / power loss???

[air121005]

when i press the accelerator nothing happens!
no power at all!
the revs creep round to 2250 / 2500 and then normal power is resumed
its only started doing this a few days ago, which at the time i also noticed a "static clicking" coming through the speakers on the stereo which has never happened before! this leads me to think a sensor or electrical component is playing up, but what?

its not a constant fault, it only seems to happen after i've been driving for about 15 / 20 minutes on my commute to work.
once the engine has been turned off, it seems to be alright again.

i've searched for a solution and the only similar complaint resulted in suggesting a MAF problem. like it confirming if it is before i start replacing bits.

thanks in advance for any advice / info you have

Occasionally, rarely, I see something similar on a 52 Polo I drive (1.2 55 E). It happens at around 30 in 3rd, or 40 in 4th: it'll be accelerating, and then the power will drop suddenly (like I've lifted my foot off the throttle) and then it'll surge back again. I reckon it's a dead/dirty bit in the throttle potentiometer (having spent many operational hours near that position). Oddly, this also happened after about 15-20 minutes' driving. Normally it goes away if I stop the engine, press the pedal a few times, and then I won't see it again for months. Unfortunately, the problem didn't show up on the fault logs, and the VW techs couldn't reproduce it.

Not sure about the static on the stereo, though. That would possibly indicate something faulting and tainting the 12V line, if it happens when playing CDs or tapes. If it's on the radio, then it could also be caused by something arcing. Or it could be completely unrelated! Best of luck in finding out what's going on...

the power / revs don't drop, the power just isn't there!
the revs do climb, but really slowly, then when it gets above 2250 / 2500 it comes back alive and the power returns

any body got any ideas???

i'd say maybe somethin to do with your turbo, does it accelorate the same (sluggish) from say 1000 rpm to about 1500, before the turbo kicks in? does it happen in all gears?

 

[air121005]

when the fault occurs its in all gears and there is no power (although the revs do rise really slowly) untill about 2250 / 2500 then normal power resumes.
i've driven it 4 times today and its been fine.

Id say maybe an intermittent sensor or cable! I fear a trip to the stealers is on the cards matey!!!!

NNNNOOOOOOOOOOOOOOOOOOOOOOOOOO!!!!!!!!!!!!!

Or do you know anyone with VAGCOM?

afraid not!

 

[air121005]

has anybody else experienced anything similar

Mine started doing that a couple of days ago..........its all down hill from here im afraid! Mine got worse, started making a really loud whine/whistle and now its gone in limp mode so it feels like its got 50bhp!!

Have a look in the tdi section, a few people think its the MAF sensor

how much is a MAF?

 

[Tall-Paul]

Ive been quoted on one before but i cant remember how much it was, it wasnt cheap though

YES! I've had this before!

It was loosing power for about 3 seconds at a time in all gears, and also when moving off it would seem to lag about 1 or 2 seconds leading to some very scary junction situations!

It went into "get you home" mode and I eventually gave in and took it to the stealers and it turned out to be a faulty bit of wiring in the TAIL LIGHT CLUSTER!!
Or so they claimed anyway, they replaced the bit of wire and it has been fine ever since. So hopefully it could just be an electrical problem causing the ECU some problems?

All the best,

Alex

 

[air121005]

it happened again this morning!

I did notice that when i tried to accelerate the was loads of black smoke!

Think i'll call the dealer and order a new MAF, as the symptoms all point to this failing!

 

[Tall-Paul]

Guess what........mines 100% fine now! Lastnight i replugged the MAF sensor in after leaving it out for a few short journeys and it went back to its normal torquey self! Well chuffed, I'm not sure how long it will last though. A MAF is about £100 btw

 

[air121005]

just had a quote from the stealer

MAP sensor (part no. 038 906 051 C) - £34.72

MAF sensor (part no. 074 906 461 BX) - £82

I seem to remember that the mercedes 2.2 dti maf sensor is exactly the same but a lot cheeper

I read about it on here
