Faults Everywhere Please Help!

[cicime]

 

I have a Citroen C4 Grand Picasso HDi 2.0L diesel SEMI AUTO  GEARS R N A M

 

Drove home from work car perfect.

Next morning handbrake would not turn off and now wont turn on?

I can only drive the car in manual not Automatic at the moment

Below are the dash errors.

 

I had a diagnostic test at local garage but all they could come up with was ABS No comunication at all??? They also said they could not clear errors??

 

ESP/ASR System Faulty

ABS Braking System Faulty

Handbrake Faulty

Gearbox Faulty

 

I believe this maybe either a faulty battery or water corosion. What I really mean is I have no idea!!!

 

Any help is so very, very, appreciated .

Welcome to the forum.

 

You will need to use a Citroen dealer for a diagnostic check but you could try to disconnect and reconnect the battery but do not do it too quickly. It could be one of the abs sensors is faulty since this may be used by the things apparently showing a fault to give the cars speed. Copied from the Technical section Common Problems pinned topic:

 

Odd electrical problems caused by wrong battery disconnection procedure.

If you need to disconnect the battery and not do a BSI reset procedure, I have found the following has not given me any problems on a 2004 and 2007 C5 and a 2003 C3:

- remove the ignition key from the car

- open the bonnet

- wait a few minutes for the BSI to shut down

- disconnect the battery negative terminal

 

When reconnecting

- ignition key out of the car

- reconnect the battery

- wait a few minutes

- insert the key in the ignition and wait a minute

- turn the key to the first position and wait a minute

- turn the key so the dash lights come on and wait a minute

- start the engine

- take the windows down and up to reset the anti pinch

- reset the clock (and radio on the C3).

check your earth leads from the battery to the engine and bodywork   Have you had any issues with the battery going flat
