I had the dreaded fast flashing indicator problem that was solved temporarily by disconnecting the alarm siren behind the passenger wheel well plastics.

From what I believe this problem is quite common so I looked up the EPC and found the part numbers.

Original No:- A2038203826
Replaced by:- A1718202526

The difference between the two is the new part number is held in place by a nut with the original a bolt, don't ask what the part number is for the nut as I could find it but it’s a M8 anyway!

This is where is got strange ordered the A171 part and was told it is now A2198203226, anyway it arrived and fitted it, all works ok.

However, I seem to have gained the chirp on lock / unlock, I was sure this was a coding option only so I have no idea how this has appeared.
