Hi All, I have a E61 525d touring 2005, can you please help with my problem, it started off by my remote key fob intermittently not unlocking and locking the doors, then progressed to not working at all. I tried the spare which also did not work, I was told it was probably the keys at fault so I ordered a new key, £100 later I tried programming it (shutting doors, turn ignition to position 1 then back again, remove key and hold down unlock while pressing lock button three times) no joy.
Someone told me it would probably be water damage to the FM/AM amplifier which is located under the rear boot spoiler, I stripped it down and found the rear window washer pipe was disconnected on a joint, I was convinced that it was this which was causing my problems. £160 for a new Amplifier later and I fitted it, tried programming all three keys again, I still can not get my key fobs working.
Because I have replaced the amplifier with a new one, is there something else I need to do, (code the amplifier or something)?
Can you please help?
