Car Forum / BMW Cars / October 2007E46 pedal linkage
My E46 330 accelerator pedal linkage seems in need of lubrication making it difficult for smooth starts with the auto box. Is it able to be lubricated? The car just had an inspection service before I bought it but this was obviously overlooked. >My E46 330 accelerator pedal linkage seems in need of lubrication making it >difficult for smooth starts with the auto box.

Try popping the hood and moving it by hand. If it doesn't move smoothly and seems to have a little hitch in it, get in there with some carb cleaner and a rag. --scott  Signature"C'est un Nagra.

I assumed there was only one possible lubrication point - on the pedal linkage itself. ie no cable or throttle body >>>> My E46 330 accelerator pedal linkage seems in need of lubrication making >>>> it difficult for smooth starts with the auto box.

If it does, there probably isn't much to be done about it unless the pot attached to the pedal has gone noisy, right? --scott Signature"C'est un Nagra.

My daughter's E46 is not fly-by-wire. She has an "00 323. I do not think the fly-by-wire made it to the 3 Series cars until the E90. >> I thought the e46 throttle was drive-by-wire. e.g. the foot-pedal >> simply sensed depression and rate of depression and 'tells' the [quoted text clipped - 4 lines] > > I do not think the fly-by-wire made it to the 3 Series cars until the E90. I dunno, I'm pretty sure my 01 e46 330Ci is fly by wire..

There's even a bimmerfest topic about exactly this. Looks like 2001+ e46'es. And this topic talks about what the OP is mentioning.. http://www.bimmerfest.com/forums/showthread.php?t=10394 Signaturethepixelfreak >>>> I thought the e46 throttle was drive-by-wire. e.g. the foot-pedal >>>> simply sensed depression and rate of depression and 'tells' the [quoted text clipped - 12 lines] > > http://www.bimmerfest.com/forums/showthread.php?t=10394 It's odd that they would make a change like that in the middle of a production run. I'm sure it's a good thing in the grand scheme of things. But, it's odd to make a change like that in the middle of the stream. In any case, you found a link that helps the OP ... >>>>> I thought the e46 throttle was drive-by-wire. e.g. the foot-pedal >>>>> simply sensed depression and rate of depression and 'tells' the [quoted text clipped - 18 lines] > > In any case, you found a link that helps the OP ... Yes - I will look into this and hopefully solve the problem. Thanks. >> My E46 330 accelerator pedal linkage seems in need of lubrication making it >> difficult for smooth starts with the auto box.

The E46 330i accelerator pedal is a Hall sensor from 2001 on (not sure about 2000; on the 323i there was a throttle cable but the butterfly could be counterdriven by a stepper motor). If it's sticky you can try to lubricate it if you can figure out how to get it apart without destroying it.

I think there was a service bullitin. NO recall. the ony way to fix it is replace the pedal module, that is if the car has the "fly-by- wire" system. it's easy to check, if there is a black box under the pedal you have the electronic version. if you have a pedal with a metal bracket with a metal bar that goes up into the dash you have a cable driven throttle. hope this helps . >> My E46 330 accelerator pedal linkage seems in need of lubrication making >> it [quoted text clipped - 10 lines] > metal bracket with a metal bar that goes up into the dash you have a > cable driven throttle. hope this helps . Thanks - it is the black box type. I found that the pedal needed bending slightly and a little rubber cleaner to make it slide more easily through the rubber grommet. The pedal action 'feels' better now but the system does require a very gentle initial movement for smooth starts. My E30 is far less abrupt.
