Hodaka Posted December 6, 2015 Share Posted December 6, 2015 Hi guys, I'm still trying to figure out what sort of conditions cause it, but I've noticed that sometimes the gas pedal becomes firmer during a drive. The firmness will be normal when I first start the car, but it can stiffen up within 10-15 mins of driving. And I don't think it's the drop in temperature outside as it's been doing this for a couple of months. I feel like I'm not providing much detail, but I'm not sure what other details I can give really... Has anyone experienced anything similar? I tried searching the forums but couldn't see anything that looked related. Any input would be much appreciated! Cheers! Quote Link to comment Share on other sites More sharing options...
OllyB Posted December 6, 2015 Share Posted December 6, 2015 Strange as the throttle is fly by wire, there isn't really anything that would cause the peddal to get stiffer, all the moving parts are in the driver's footwell.... Maybe the pedal mechanism is binding up a bit, have you tried a bit of spray oil on the pedal pivot... Quote Link to comment Share on other sites More sharing options...

Not sure if this could cause it, but I noticed the carpet (?) at the back of the footwell has lifted somewhat as well. Could that have an affect do you think?

88 Zed Posted December 6, 2015 Share Posted December 6, 2015 Could be a carbon build up on the inside of the butterfly flap? Get a bit of carb cleaner and give the throttle flap a clean if you have no joy with lubricating the pedal. I cleaned mine during a service the other day and was surprised at the amount of crap I cleaned out! Quote Link to comment Share on other sites More sharing options...
OllyB Posted December 6, 2015 Share Posted December 6, 2015 Could it be snagging on the carpet? Quote Link to comment Share on other sites More sharing options...
Hodaka Posted December 6, 2015 Author Share Posted December 6, 2015 Thanks guys. I'm a bit clueless, so wanted to clarify what you guys meant. Is it clean and lubricate the spring in the red box, then try carb cleaner on the thing in the blue box? And yeah Olly I was thinking that too. Do you know how the carpet is meant to be attached to the wall of the footwell? I can't see any clips or anything. Quote Link to comment Share on other sites More sharing options...
OllyB Posted December 6, 2015 Share Posted December 6, 2015 Yes lubricate the pivot in the red box. Do not spray carb cleaner on anything in that picture..... 1 Quote Link to comment Share on other sites More sharing options...
88 Zed Posted December 6, 2015 Share Posted December 6, 2015 Apologies! I've just realised there fly by wire throttles so carb cleaning the throttle probably wouldn't work! Too much beer last night I think : s Quote Link to comment Share on other sites More sharing options...
Hodaka Posted December 6, 2015 Author Share Posted December 6, 2015 Gotcha, thanks both for your input! I'll just clean and lube the red bits. Quote Link to comment Share on other sites More sharing options...
Ridz Posted December 7, 2015 Share Posted December 7, 2015 The OEM carpet in the drivers footwell is secured onto a plastic peg which is attached to the front of the drivers seat rail. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted December 7, 2015 Share Posted December 7, 2015 As above. Never experienced this issue before. Quote Link to comment Share on other sites More sharing options...
samsniss350z Posted December 8, 2015 Share Posted December 8, 2015 As Ridz said if you're using a mat that isn't located on the little plastic peg then this could have crept up and could be causing the interference you are experiencing.

Watshot Posted December 8, 2015 Share Posted December 8, 2015 I think he's talking about the carpet and how it attaches to the baulkhead. Not the mats. Quote Link to comment Share on other sites More sharing options...
Mark@Abbey m/s Posted December 8, 2015 Share Posted December 8, 2015 Could be a carbon build up on the inside of the butterfly flap? Get a bit of carb cleaner and give the throttle flap a clean if you have no joy with lubricating the pedal. I cleaned mine during a service the other day and was surprised at the amount of crap I cleaned out! the throttle pedal isn't connected to the butterfly with a cable , as Olly has said the car is fly by wire so no hard connection between the pedla and butterfly.

Hodaka Posted December 8, 2015 Author Share Posted December 8, 2015 (edited) Sorry guys, I'm probably not being clear as I don't know the technical phrases for everything! It's this carpet thing shown below, not the mat. It used to sit against the bulkhead (is that what it's called? The white-ish thing in the pic), but after I took it into the garage a little while ago, it seems to have come loose. In the pic I am peeling it back with my hand, just to show it's loose. Can I just used double-sided tape or something to hold it in place? Edited December 8, 2015 by Hodaka Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted December 8, 2015 Share Posted December 8, 2015 That is just sound proofing, so just make sure it is well away from the pedal fulcrum because if it is snagging then this may well be your issue. Glue or double sided tape should do the trick. 1 Quote Link to comment Share on other sites More sharing options...

Hodaka Posted December 8, 2015 Author Share Posted December 8, 2015 (edited) Hi guys, So I used double-sided tape on the carpet, which has definitely sorted the carpet pulling up. I also secured the floor mat to that plastic clip under the seat. Might be quite minor, but it pleased me a lot to know those are sorted, so thanks for your input! Also I noticed the pedal stiffening up on the drive back from work today. When I got home, I literally rubbed the spring with my fingers and got a bit of the cr*p off it. Tried the peddle again and it was much lighter again. So it seems to be that spring area (pedal fulcrum?). I'll clean it and lube it, but I was wondering if someone could recommend what lube I should use? Cheers guys, Hodaka Edited December 8, 2015 by Hodaka Quote Link to comment Share on other sites More sharing options...
88 Zed Posted December 8, 2015 Share Posted December 8, 2015 WD-40 being carefull not to get any on the actual pedals, that would be bad! 1 Quote Link to comment Share on other sites More sharing options...
Hodaka Posted December 8, 2015 Author Share Posted December 8, 2015 Wow, that was quick! Will WD-40 need topping up frequently? Just asking as the stuff that's on there currently felt a bit "thicker" in consistency, so was wondering if that stuff is longer lasting. Sorry for the barrage of questions. I'm seriously clueless about this stuff - really do want to learn so I'm not so useless! Quote Link to comment Share on other sites More sharing options...
88 Zed Posted December 8, 2015 Share Posted December 8, 2015 Well WD-40 is a very thin oil and wil need spraying on, I'd try that 1st and operating the pedal to see if it gets any better, the thicker stuff is probably some sort of grease, I would try the WD-40 1st tho as its not as messy as grease! Just be carefull not to get any on the pedals for obvious reasons í ½í± Quote Link to comment Share on other sites More sharing options...
OllyB Posted December 8, 2015 Share Posted December 8, 2015 (edited) A grease would be better, just use sparingly or 3in1 oil. WD will give a short term fix but will need regular top up and will probably drive some of the old grease out...

88 Zed Posted December 8, 2015 Share Posted December 8, 2015 Very true but if you use wd40 to confirm that's the issue and then apply some grease as a long term solution rather than using grease then having to clean if off if the pedal needs removing to fix it?

Stutopia Posted December 8, 2015 Share Posted December 8, 2015 The spray on white lithium grease I use on my clutch pedal spring seems to last a while and clings pretty well, makes a bit of a mess when you apply but nothing you can't solve with a well placed rag.

samsniss350z Posted December 8, 2015 Share Posted December 8, 2015 Have you thought of using Q20? Its a spray on lube but doesn't seem to leave a residue like WD, its great for firearms and all sorts of applications, but then again its German so I'm not sure if their claims are true LOL. 1 Quote Link to comment Share on other sites More sharing options...
