the warning light flashes while the engine is running,is there a simple remedy for this or shall I just take it along to the Citroen dealer for repair?
There's no quick fix as the cause for the light comming on could be one of many things and just replacing them in the hope of a cure will work out very expensive!! much cheaper to get the fault codes stored in the engine computer read then replace the faulty item/s.
Any independant garage or even tyre & exhaust places will have the required equipment to read the fault codes and will be a lot cheaper than the main stealership!! expect to pay around £20 from an independant or £70 + from the stealership
