Hello.

I have audi A4 B5 1.9tdi (1996) 66kw with 1Z engine.

And now I have problem. Car wont rev over 1300rpm. I allready change brake light switch but doesn't help.

If brake pedal is released engine wont rev over 1300rpm and brake lights are off
If brake pedal is pressed engine rev normally but brake lights are on.

Can anyone help please??

Sorry for my bad english but I come from Slovenia

 

I found that the problem is around brake lights because when I take light bulb for brake light out car work normaly. So I must look for the problem around brake lights wiring
