Stuttering car!

[traumapat]

I was planning to clean the throttle body, so i will deffenatly do that this weekend, where is the temp sender? i will have a look at that also.
Cheers

temp sender should show up with vagcom if its faulty. ask someone local if you dont have it if memory serves its on a pipe running down the rh side of the engine. you need to remove the covers ect... but you need to see if its throwing up a fault

erm i think its about £85 exchange basis? £20 surcharge i think until you hand in old one... something like that.

yep if going via a dealer... swop over in the car park..

some are getting them cheaper via ebay but many have proved faulty.

Mine just had exactly the same problem. The crankshaft sensor was faulty. It didn't show up on VAG-COM for nearly 6 months and one day just broke down. Took it to my local repair man and less than £100 later, had my old car back as good as new.

Hi, mines being doing the same thing since I bought it last year just as you’ve described it. I’ve had the plugs / filter changed and it didn’t help. I’ve had the temperature sensor replaced, that didn’t help either. The garage suggested it could the dual mass flywheel (some kind of sensor on this?) and that they aren’t cheap to replace, or may be a coil issue?

Cheers all.

I'm hopefully gonna take it over to a vagcom garage next weekend and see what they can find. I'm on 24x7 standby at the moment so pretty restricted in terms of travel for the next few days, but seeing as I've been putting up with it for so long, another week will hopefully make no difference!

I decided to push the car a bit harder on the way home, and the problem was greatly reduced. I've realised that the problem is mostly when I'm driving right near the bottom of the gear's rev range and when my foot is almost off the accelerator but still has a faint amount of pressure. Not exactly feathering the gas, but not far off it. Once past the top inch or so of the pedal's travel, the acceleration is smooth and constant. If you imagine putting the car in second gear at 30-40 and then taking your foot completely off the accelerator, as the car decelerates and is almost at stalling point, if you were to then lightly press the accelerator again so as not to stall it, that's around the position where the power falters.....

And before anyone asks - no, I'm not simply talking about "kangarooing" the car with bad gear changes......!

Sorry to hijack the thread but i think i'm having a similar problem.

Last weekend my car went into limp mode, i disconnected the MAF and it drove better but not to its full potential. I replaced the MAF this week and its no longer in limp mode.

But....

if i'm cruising along and i put my foot down in 2nd and 3rd gear the car jerks as if dropping boost then it picks up and goes like usual.

Also i can't hear the turbo whistling anymore but instead it sounds more like a whining noise when on boost.

Its beginning to annoy me as its getting hard to drive the car smoothly!!!

Any ideas?

The car is a 54 ibiza cupra 20vt (BBU engine) by the way

 

[Bananaman]

Yep, that indeed sounds similar!

I've not got mine fixed yet. Phoned psituning in Newcastle-Under-Lyme, but it'll be 2 weeks before i can book it in to get looked at. Got a week off soon, so am gonna take it in then and see what they can do. I'll post back when I have more info, but in the meantime, if anyone's got any suggestions......

 

[Bananaman]

Just a quick bounce of this thread to let you know that I took the car into psituning this afternoon.

Would you believe it, the bloody thing behaved itself all the way on the journey over, so when the mechanic checked it over, took it for a spin, etc.. - no problem to be found!!

It's also behaved itself all the way home, so after bracing myself for an expensive repair, I'm rather pleased he didn't find a problem. It was also recommended that I drive the car around for a bit, and if ever the problem is persistent enough to take it back and demonstrate the problem, then we'll also hook it up to an airflow meter and see what the problem could be.


However, just on another note.... I can't recommend psituning enough. Very friendly staff who really know their onions, and after the mechanic had given the car a good look over, throttle body clean, checked the sparks, etc.., I was only charged half an hour's labour! A very fair, friendly and professional outfit - I just wish I'd taken my car there for the previous services!

Hi all,

Im new here, I hope thread bumping isnt looked on badly here, I used the search funtion to find it and thought it best as opposed to staring a new thread.

Ive recently purchased an 03' Leon Cupra R and have the same issue as described in this thread. it only appears to happen it 1st gear and around about the 3000RPM mark. Has anyone heard any more? solutions etc? Bananaman how is yours behaving?

Ive also read alot about checking the DV... simple question but what is one of those?


Cheers,

Dan.

Hi mate!

Firstly, welcome to the forums! Don't worry about the thread bumping, as we all know how frustrating it is when you have a problem with your car and you want it fixed...

With regards to the problem I had - past-tense - I've never felt it since. I'm not sure whether it was the clean of the throttle-body that did it ( the guy at psituning told me that he'd flushed it through when I first reported the problem) or the clean of the sparks, but I've been lucky enough not to have it again since.

I've also had the guys at psituning do a major service on the car since this problem last year, so maybe this is helping to keep the car in tip-top condition?

 

[danthemantucker]

Cheers mate. I find these forums to be a great help, Ive owned BMWs for years and always been members of forums, so much useful information and support from others. Im glad ive found this place.

The garage I brought the car from "supposedly" gave it the service that included a new set of spark plugs. I might have to check this out though. I used to do quite abit of work on my E36 BMW but it was a considerably older vehicle. As Ive never worked on a car this new im a little tentative to just start unplugging stuff etc. Are there any guides dotted about on changing\removing the coli packs\spark plugs, cleaning the throttle body? also the 'DV' question I asked, could you help me out with what it is, then I can research it abit.

The car is having the temp sensor changed today as it was causing the engine management light to come on. Im not sure if that may have had any effect on it.

Again thank you.

Dan.

the DV is just a diverter valve that effectively recirculates air for the turbo. Its a crappy plastic one as standard and is fairly prone to break, theres like a gajillion and one posts on it. On a side note, if you take the engine cover off and actually look at the engine it's not really that intimidating lol.

 

[Bananaman]

Just another quick point, Dan. I had my temp sensor changed last year too in the hope that that might fix the problem, but it didn't. It stopped the erratic behaviour of the temp gauge, but had no long-term effect on the stuttering. Hope that helps!

 

[Bananaman]

Oh - and I've just re-read your post. I guess if its the engine management light coming on, then it'll be the coolant level sensor that's being changed, and not the coolant temperature sensor?

I don't think that'lll solve it either... I'm getting the cold-morning "3 beeps" fault too - a well-known fault - and yet the stuttering has gone....

Cheers Mr JB, much appreciated. I did search for DV but the search function said that was to short as as I had no idea what the abbreviation stood for I was a little stumped! Ill have a look now I know though. It wasnt so much how it "looked" but It was more that just unplugging & removing stuff may cause issues if i didnt do something else first if you see where im trying to go with that. nervous, new motor un all, costs me alot of hard earned pennies

Bananaman your probebly right, my temp gauge jumped about all over the place.

I hope I can get it solved as its one of the two thorns in my side. the other is an occasional clunk from the rear of the car. usually when im reverse off my drive, its on a slight slope, it happens just as the slope levels out, not all the time though. I got the SEAT guys to take a look but they said they couldnt see anything obvious so who know

 

[selfagg]

I'm also having the same problem with my car, although it is a TDI, so not sure if that helps narrow down the solutions...

 

[ryan106]

My car is doing the exact same I get a hesitation on light throttle usually around 2500rpm and can be lumpy through the rev range on light throttle. I pulled the MAF sensor and the car didn't hesitate at all although it didn't fully boost either. I have a new MAF ordered through the dealer and getting it tommorrow so I will report back on how this has changed my car hopefully sorts it, it definately is annoying not driving smooth.

 

[selfagg]

If the MAF is at fault, would it show on VAGCOM?

I've just had mine on there, looks like the MAP sensor is at fault, although would it cause the stuttering?

 

[ryan106]

Just to update on the hesitation I got my new MAF sensor and made absolutely no difference at all, going to go for some new plugs next as its starting to get annoying.....

 

[scazms]

howye now? i had this problem before, it was a dirty connection at the air mass meter, just pull it out and it should be ok, also engine speed (impulse sender) sensor could be the cause
