Hello, this being the auto electric forum,I thought it prudent to post here. I have also posted on the 7 Series forum but I'm new here so didn't realise there was a specific forum for electric issues!!
Sometimes, ONLY in the colder months of the year my park distance circuit picks up a current from somewhere independently of the ignition. With the fuse (#64) inserted it causes a feedback to the ignition when the car's switched off and it comes to life, dash lights, brake light, alarm tripping,etc. I have even had it where I've taken the key out and the engine's still running. As soon as I take the fuse out, it all goes dead again but the PDC circuit is still picking up some current and works until outside temp gets warmer, by even a degree or two, then it cuts out as well.
I need to know where the circuit could be picking up this live feed from, and it's strange that it only occurs when it's really cold, and only sometimes. Appreciate any advice. Alternatively, if anyone knows any competent, honest and competitive auto electricians in the manchester/northwest area please let me know.
I really need to sort this out as I'd rather not just use my PDC as normal with the fuse inserted and then wait for all the lights to come on, drain the battery or embarrasingly blare out the alarm. At the moment I've left the fuse out, but my car is not a small motor and the PDC comes in extremely handy. You know what I mean!! Thanks
