Issue with interior fan and central locking from flip key

[stoyanganchev]

Hello! I have an Issue with interior fan and central locking from flip key. When I lock the car with the key it is working, but with the remote control NO. The issue with the fan is that when I press the brake the speed of the fan go up. I checked the minus point near right rear light. When I switch of the brake switch, the issue is gone. I know that is the comfort Modul. Can you help me where to search the problem.

Does the remote work if you hold the fob next to the steering wheel?

[stoyanganchev]

No it is not working.

Have you tried replacing the remote fob battery and initialising it following the procedure in the handbook ?

Has the remote ever worked?

As Paul asked, has the remote ever worked since you have had the car?
Have you tried a new battery in the fob?
Have you checked to see if the fob is transmitting a signal?
Have you tried re programming the fob? Needs to be done diagnostically & will requre the 4 digit security code.

I would hope you have checked all these things before getting involved with removing the CPH?

[stoyanganchev]

The car was bought as new from my father. It worked but suddenly stop working. The remote is tested and give a signal, but the car didn’t receive it.

I tried to relearn the key and the CPH but without success

Sounding like its likely a CPH issue then, If you get a second hand unit you would need to copy or swap the EEPROM over from your original.
Note that the CPH has nothing to do with the interior fan though so would need looking at separately.

When I lock the car with the key, the warning lights are not turning on like my fathers C5 and the Xsara of a friend. Is it normal?

[Paul-R]

When you say locking with the key do you mean you physically use the blade to turn the key barrel in the door handle or simply press the buttons on the fob?

[stoyanganchev]

I mean physically use the blade to turn the key barrel in the door handle, then the car lock the doors, without turning the hazard, but when I try to use the buttons on the key is nothing happening.

[Paul-R]

Locking the car with the key blade only locks it, the interior ultrasonic intruder detector is disabled. This might be why you're not seeing warning lights.

You say "The remote is tested and give a signal, but the car didn’t receive it." What was used to test the remote?

[stoyanganchev]

It was tested on a device in a key repair shop.
