adam-m2 Posted October 6, 2014 Report Share Posted October 6, 2014 Hi, not sure if I'm posting this in the correct place as I'm new to here, but any advice would be greatly appreciated I've recently bought a 2005 e46 convertible, and the wireless key range is really poor, I literally have to stand next to the car to be able to unlock it wirelessly, any further than a meter away and it doesn't work. I ordered a new key for the car and programmed it accordingly, and still had to same issue so I know the key is not the issue. I believe it's most likely one of the receiver units in the car, can anyone confirm specifically what is most likely failing? And how I would go about replacing it?

Chimp Choker Posted October 6, 2014 Report Share Posted October 6, 2014 Any interference possibilities. If you hold the key at the back of your head and press the lock/unlock does it work then www.bobsbmw.co.uk Quote Link to comment Share on other sites More sharing options...
adam-m2 Posted October 6, 2014 Author Report Share Posted October 6, 2014 Hi, thanks for the replies. Indeed holding it to my head does help, though it isn't ideal. I really want the wireless key fob to work from a reasonable distance. Quote Link to comment Share on other sites More sharing options...
adam-m2 Posted October 6, 2014 Author Report Share Posted October 6, 2014 Fairly sure there's no interference issues, tried in different locations and removing possessions from the car Quote Link to comment Share on other sites More sharing options...
bungers Posted October 6, 2014 Report Share Posted October 6, 2014 If they're anything like the coupé I would say you're looking at a replacement diversity amp, just make sure you get one at the same frequency as the one you're replacing!

adam-m2 Posted October 7, 2014 Author Report Share Posted October 7, 2014 Thanks, any idea where this is located on the convertible? Quote Link to comment Share on other sites More sharing options...
Chimp Choker Posted October 7, 2014 Report Share Posted October 7, 2014 Sits in the boot near where the CDC is. Carpet out job iirc www.bobsbmw.co.uk Quote Link to comment Share on other sites More sharing options...
the_driller Posted October 7, 2014 Report Share Posted October 7, 2014 I think but don't quote me the reciever is in the wing mirror. Sent from my GT-I9500 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...
adam-m2 Posted October 7, 2014 Author Report Share Posted October 7, 2014 Thanks, I took a unit out earlier which I thought it was, a thin black/grey box located on the left side just below the CDC, After taking it out/unplugging it, the remote unlock was no different so it must have been the wrong part? it had 4 connections.
