I'm telling you they would!switchs under clutch and brake are fine , also these would not stop the cruise control from powering on ,they would just keep disengaging it according to a forum on bimmerwerkz
im stumped on this one
The car needs to know the what the clutch is doing and also the brake application before allowing the cruise control to engage.
Would love to know how you tested them.
A diagnostic will tell you exactly what is wrong.

i just took them out and had a look at them john , i did run a diagnostic on inpa and nothing showed the only reason i thought they where fine was because of what i read on another forum that if they where faulty the cruise control light would still come on on the dash , if the brake one was faulty would that not stop the brake lights from functioning ? , i might just chance it and change them as you siad there only cheap as im running out of ideas
When you press the cruise button on the steering wheel, what happens? Does the cruise light come on?

tested it on inpa all buttons working on the steering wheel , this might sound a bit dumb but could it just be the bulb in odometer when you activate cruise control aside from the little symbol coming up on the odo does anything else come on say where the mileage is or something

i haven't a clue its all knew to me
i thought the only lcd bit was where the mileage is displayedIf it was something like that it would have come up on the diagnostic.
Check out the last post in this thread.

Try the same with your clutch switch.
It may not be broken but just not making proper contact with the pedal. Hence wy it didnt show up on the diagnostic.

okay little update tested the clutch switch today with thourough daignostic as you can see from the pic it works fine highlights when clutch is pressed and clutch switch is activated -deactivated , tested the odometer the cruise control symbol lights up and the cc buttons on the mfsw work , i then went into the cruise control option which i hadn't seen before and it siad no response from control unit so i presume i need a new module does anyone know if i can just grab one from any e39 or would it have to be from a 525i also will it have to programed or is it plug + play thanks

oh right no worries mate it sounds the exact same as what happened to mine.. hope ya get it sorted mate.. i think their was a cruise control unit for sale on the site her irc..
Ok done the above and the light came on then went off when I started car/touch brake pedal.
So now I'm wondering what or where the MAF is? Is it a big job? Costly?
Thanks lads,
Rob.

Why don't you get the car connected up to DIS? If you're still stumped I'll hook it up at Blarney.
