Title: Accelerator pedal problem?
Post by: Exonian on 12 April 2008, 14:19
A quick hello to all in the mk5 section  :smiley:, not new to VWs or mk5 Golfs for that matter as I had a modified 140 TDI before and a good few TDIs and GTIs etc before that, but have a question about my fairly recently acquired GTI. It's a 40,000 mile 54 plate early car in grey. Manual btw.

This is aimed at those who have slightly older and higher mileage cars really but it would also be useful for owners of newer GTIs to give me some feedback.
Not sure if my car has an issue with the accelerator pedal, it seems pretty slow to pick up unless the pedal is pushed in about an inch or so. Once past the first bit of deadish travel it's off and away.
I can remember test driving a few before I got my previous diseasel and don't remember the dead throttle pedal travel. My wife's Polo is fine, touch the pedal and off you go, my Diesel mk5 was fairly similar to the GTI but then again the 140 doesn't have quite the same low rev urge of the 130 and 150 1.9 units despite nominally the same torque figures in my experience.
I don't remember many of my 1.8Ts and 1.9PDs feeling so dead on throttle pedal application and there's no play in my GTIs pedal so the spring 'feels' okay. Certainly after driving a Polo GTI with it's razor sharp throttle response my 2.0 TFSI seems 'not quite right'.

If this is typical of GTIs then has anyone tried the Sprint-booster device?

TIA    :smiley:

Ah well despite everyones reluctance to talk to me I thought I would reply to myself just in case anyone else has the same concerns.

Firstly I simply got the car re-mapped. The pedal now seems to do something in the first few mm of travel so that answers my question there - the mk5 Golf has dead travel built in. Having tried a Polo GTI which had razor sharp throttle responses I wrongly hoped the Golf was the same.

And to the last bit of post #1, I managed to find a forum member from another forum who is local to me with a Sprint Booster. It's great when you want a blast but not too easy to control in stop start traffic especially if you have a re-map. Undecided if I want one or not as at over £150 its not exactly cheap. :undecided:

I'm not sure about everybody else but there isn't even a mm of dead travel in my pedal????  Can't comment on why the remap sorted it out??

i dont appear to have any travel either, although a bottom hinged pedal did take a bit of getting used to

I dont have any travel at all before my engine speed increases, and never saw your first post Exonian, apologies  :smiley:

im not sure really, iv have put it down the the turbo kicking in, which makes you think your havnt put your foot down untill it does... until that point its almost like not moving

is this a rev issue, as in you dont go very quick till you hit a certain rev range ?, i.e over 3k etc ?

Ah replies! I was beginning to think I smelled bad!!!

Thanks for the feedback. Maybe my Golf has other issues? Maybe the spring is getting a bit worn on the pedal?I'll have to invest in a fault code reader sometime I guess, save keep taking it to VW and it's out of warranty in a few months  :sad:

Thanks for the feedback anyway.  :smiley:

The car does seem a bit flat after several modified 1.8Ts and TDIs but revs cleanly. But the original post is more to do with the pedal itself (I think  :undecided:)

pedals are quite cheap from what i remember

if you push your pedal an inch does the engine rev?

Yeah it revs with no load on the engine, it just feels a bit unresponsive on light application.
For scientific reasons I've just put the car back to standard mapping and driven it about 10 miles, funnily enough it doesn't feel so flat now(?) perhaps I'm just getting used to the car.
Maybe it was that before I bought it I read rave reviews for all those years but actually driving one after a raft of remapped cars it just felt a bit flat low down. Feels fine with the re-map on but even then it doesn't have the torque kick of a mapped 1.8t which is traded off against the fact that it revs much more smoothly.
Overall I love the car and wish I'd bought a GTI a couple of years ago instead of the TDI (having said that, it was a perfectly good car in itself).

Right I'm going to shut up on the subject now, I've decided that the turbo must be far more progressive than the older GTIs and hence it just feels a bit lacking if you're gentle. Many thanks for all the replies and assistance. :smiley:

hum, gotta have to check myself when i go out next, because i have sorta thought the same... but in my mind, it may be the two things, the 2l engine, then the turbo.. making it seem like the 2l engine just seen slow.. when its not.. im just use to the turbo.. if that makes sense :s

your problem sounds like the normal GTI behavior, i.e not allot low down, but flies then gets over 3k or so

Welcome Exonian  :smiley:

Glad you convinced yourself you never had a problem after all  :grin: :grin:

I think we may of all been having our afternoon nap when you posted?  :wink: But you'll find were a friendly bunch, always willing to help  :smiley: (except during afternoon kip :wink:)

Might be worth trying a throttle body reset - you can do it with VAGCOM or open bonnet and turn on iginition until the high pitched squeel stops (this worked on the 1.8T's and I am sure works on the TSI too).

??? does the bonet have to be open to do this?? im sure i hear the electric squeel everytime i turn on

It will do it without the bonnet being open if its been left for a while - if you dont start up immediately that is.

Thanks for that little nugget, I have tried that on my 1.8t's but was unaware you could perform the re-set on the 2.0TFSI. I'll give that a go later, I'm always keen on bits of maintenance that don't cost any money  :grin:

Thank you for the (belated!) welcome, I was quite taken aback by the lack of feedback initially as it's usually quite busy on these forums, that's why I persevered!!!

I won't say I'm convinced I don't have a problem but I'm satisfied enough not to want to spend £50 on a new accelerator pedal  :grin:
Maybe I'll invest in a Sprint-booster one day, maybe not.... :undecided: That would cure it once and for all.
