I'm a newbie so hello to everyone and thanks to everyone for all there help.
I have been reading this forum for several years because of an on going problem with my C4 gp but have only joined today in the hope that I can get some help for my problem...
I have been having problems with my electronic parks Ng brake for about 2 years now when it first happened I took it to my mechanic who I have been using for years but he couldn't find the fault so told me I had to take it to Citroen's.i did this but instead of helping me they just gave me a long list of things that were wrong with the vehicle and tried to sell me a new car.things like £1500 to change timing belt.
I then took it to another garage that my sister in law uses and he changed the egr valve and put a new turbo valve on it or something and it worked great for about 10 months then the parking brake problem started again so we decided to change all the brakes because they were wearing in the hope it would solve the problem it didn't.know the reverse lights are on all the time and I have had to remove the bulbs
The not is due on Saturday and it won't pass without reverse light so I have bought a launch from 129 to try and find the fault.
The codes which it as thrown up are
P1351 IDM Input voltage multinational/ignition voltage coil high voltage
Preheating relay circuit.relay supplied and plugs never supplied
DTC status
Permanent fault
Preheating relay circuit.control in short circuit To earth or open circuit
DTC status
Intermittent
And now for the big one
Fault automatic release of the electric parking brake:reverse gear detection incorrect. Cohereance
DTC status
Permanent fault
It is a manual gear box and mechanic said reverse switch is working fine.
Any help would be most welcome as I'm at my wit's end.
Thanks for all your help
