yetiecouple Posted January 6, 2015 Share Posted January 6, 2015 Hi was wondering if some one could help. The fob key would not work so I unlocked the car using key in the door, the alarm went off I put key in ignition to start the car but but the engine immobolised. Now car will not start. Have been told the fob is not working and fob & car needs to be reset, dealer has quoted £108 to hook up to computer to assess the problem. We do not have a second key and ever time we open car alarm goes off. Message board has also said ecc mode. Do we have to go through dealer or is there another way around it?

Randombloke Posted January 6, 2015 Share Posted January 6, 2015 For the little it will cost, have you considered replacing the battery and eliminating this from the list of possible faults? Quote Link to comment Share on other sites More sharing options...
yetiecouple Posted January 6, 2015 Author Share Posted January 6, 2015 I have replaced battery in fob but still does not work. The car battery is only about 1 1/2 old. Quote Link to comment Share on other sites More sharing options...
paul.h Posted January 9, 2015 Share Posted January 9, 2015 There have been a few cases possibly similar to this and they have been directed towards a dealer for a check using the correct diagnostic equipment - but nobody has yet reported back having been to a dealer to have it checked but neither have they reported back having solved it. One owner of a C4 even went to the extreme of replacing the immobiliser parts, the alarm, the ecu and keys from another car and still has the problem, but has not tried a dealer. When you replaced the fob battery did you re-initialise the fob following the procedure in the handbook ? Quote Link to comment Share on other sites More sharing options...
