Hey guys, I can't thank you enough. I'm going to work on both this weekend. Great info !!


andrewwynn; If you click on his link about the antenna module. Scroll to the bottom left and it shows the one for the E53. Shows the module location at the top of the decklid under a plastic panel and the antenna in the glass. Its very easy to get to.

What I'm going to go and you should try is. Take the module out, take the covers off and spray all the boards with a known electrical cleaner/lube. I use ACF-50. I've fixed many problems this way on motorcycles circuit boards form the 80's to the external transmission neutral safety switch on my E-53. I've also fixed dash issues on 90's bikes with electronic dash's like that where the reset buttons stopped working. Literally just sparing and cleaning the circuit boards and plug in connector prongs.

While a board could be lose or have a bad solder its most likely corroded, its doesn't take much.

On my 911 the Germans are known for having cold shunts on there soldering of circuit boards. If you have a cheap solder gun and you see a bad solder, you will see cracking all around the solider, all you do is touch the pin and it will re-solder. Fix boards on my 911 this way and was easy, harder to get the board out of the car.
