Car Forum / BMW Cars / April 2004Stiff Accelerator
I have a 2000 323Ci but the accelerator pedal is very stiff. Does anyone know what might be causing this. I heard it may be an electrical fault. Anyone know anything about this. > I have a 2000 323Ci but the accelerator pedal is very stiff. Does anyone > know what might be causing this.

They replaced the "accelerator module" on my 2002 E46 under warranty. There is no accelerator "cable". Leong > > I have a 2000 323Ci but the accelerator pedal is very stiff.

The throttle cable does nothing until about 85% throttle. Prior to that, it's controlled by the DK motor. BMW was hesitant to let the system take the car to full throttle electronically, at first, but discarded the cable quite quickly in the end. Brett Anderson KMS www.bmwgears.com Do you mean that on modern engines (3.0l M54 for instance) there's no cable going from the pedal to the engine ? Is there a potentiometer instead ? > > > There is a known problem with sticky accelerator pedals on E46s. They > > > replaced the "accelerator module" on my 2002 E46 under warranty.

That is correct. The E39 M5 was the first with this setup IIRC. All current I6 engines (2.0/2.5/3.0/3.2) and valvetronic engines are that way - not sure about the older V8's and I4's.

None of the BMW V12's have had cable throttle, none since the early 80's double M30 prototypes at least. V8 got it in 99 model year. I6 got the partial system in 99 model year, fully electronic in 2000. Not sure when the I4 got it, but probably with the introduction of the N44. Diesels? Anyone? According to ETK, they are also electronically controlled.

FWIW, most of the car mags love the electric throttles - Car & Driver says that BMWs have "brilliant throttle response". ;-> Floyd |
