View Full Version : Eliminate gas pedal slap when lifting?

I know this is a little thing, and I have accepted it since I purchased the car, but for some reason it pushed me over the top this evening. Maybe I am nuts, OCD, or whatever the term is that describes us folk. Driving home from work on this beautiful evening, I decide to run through the gears quicker than my normal pace. After a good run through 1st with the Bavarian symphony playing their wonderful music, a quick shift is rewarded with the cheap plastic slap of the gas pedal after a quick lift. Rinse and repeat for 2nd, and 3rd. :facepalm

Has anyone tried to silence the sound the gas pedal makes when it quickly returns to and hits its idle stop? I'll dig into it tomorrow, but just wanted to see if anyone has any tips.

Cheers

Hmmm.....can't say I've ever heard mine do that. Not at home now to see if I can replicate the noise.

Can't say that I have heard that ever. Maybe I am not fast enough on lifting foot off the gas pedal between shifts. Reminds me of the Top Gear episode, 500 ms between shifts was too long.
- or-

OCD a little :)

I don't lift my foot off of the gas, i just lift enough to select my target rpm. i would contend that you're using poor technique if you're picking your foot up that far and that fast, but Im no instructor.

I find it pretty crazy that you can hear that over a redlined motor.

Hm, when quickly shifting, I have always come off the gas completely to get the RPMs to start to drop as fast as possible, then lightly back on the gas as I select the next gear and engage the clutch at the correct RPM. It's not the end of the world, but it is one thing my dad and brother noticed when they were test driving my dad's '04 X3, so I figured it was across all BMWs from that time frame. Maybe it is something in the water down here that makes us coonasses a little crazy?

If I pull up on mine there is at most maybe 1/16" play that makes a slight clicking sound but I'd be surprised if I could hear that while driving. I will try to remember to listen for it when I have it out tomorrow afternoon.

I know what OP is talking about and it drives me INSANE as well. I'm sure everyone else has experienced it, but never noticed.

It's taking your foot from depressing the accelerator to some point, and lifting your foot quickly off the pedal. The pedal is coming back to its resting point. It happens every time I shift gears.

If the slap is annoying, don't come off the gas so fast.

Yea...I think it's one of those things you just gotta live with

paid particular attention on the way home, don't even come close to lifting fast enough to generate the sound you guys are talking about. to generate the sound i pretty much started driving like garbage because it was so unfamiliar.

i vote you guys try finer pedal modulation - you don't have to come off completely or so quickly to still be "off" the throttle completely.

I know what OP is talking about and it can be pretty damn annoying. Is it because these car's have the electronic throttle thingy?

I was test driving a 323it/5 and noticed that the pedal feel was much nicer, probably because I'm used to the old fashioned throttle cable.

I get this when I heel toe. Its annoying...and I have a touchy pedal and still get it.

I just live with it and keep the music on

I've never noticed this noise. Now that I know to listen for it, it will probably drive me nuts; assuming I ever get my car back.

Some must be louder than others. I tried it last night and could just barely hear a click when blipping the throttle at slow speed/rpm. No way I would hear it in normal driving.

The brake pedal also 'slaps' when lifting foot off, on these cars...
It doesn't do it much when I drive, but does very often when wifey drives...
