Lets see, where do I begin? One night in late June I got in my E39 and had to move it around my driveway when I noticed: No interior gong No Radio/clock No A/C No heated seats No reverse lights Steering wheel took a while to lower into position No blinkers on dash No fog light symbol on dash Key fob functions weren't working Then all of a sudden the gong came back and everything started working again. Then the very next morning I start the car but the problems came back. My mechanic informed me that the ignition switch was fine so that I would need another instrument cluster. I get one from him the following week. Everything was fine except for a things: 1) Automatic transmission failure light was illuminated (I have a 5-speed M/T) 2) DSC light illuminates before shifting into 2nd gear and stays on afterwards 3) No back-up lights as I assumed the cluster came from a E39 automatic I figured I would get another used cluster that came from a 5-speed E39 as I needed the car to take to FL within the following week. However, we decided to bring the E46 instead so I leave the E39 in the garage. After getting back from Disney, I drive my E39 for a few days and I noticed at times the blinkers on the used cluster wouldn't show up on the dash but then it would come back on. Low and behold, the used cluster failed, only this time some more features weren't working: No tach No Speedometer Fuel and temp gauges giving out false readings No license plate lights and the headlights/taillights stay on until the car is turned off No interior amber lights EML light is on Airbag light is on Fortunately I had a 30-day warranty so I had my mechanic return the used cluster and order a cluster from Bavarian Auto Recycling out in Cali with a 6-month warranty and with the options that my car had (xenon, 5-speed, no nav, etc...). However, after installing the new (used) cluster from Cali, it didn't cure a thing . My shop told me to have the cluster coded to the car so I called various dealerships to see if it can be done. Unfortunately a used cluster cannot be re-coded so I was given a quote of $860 for a new cluster to be coded to my car with labor. However, I think I have more than the cluster problem because if the first used cluster worked for a bit and then failed with yet more problems, the 2nd cluster from Cali should have worked fine. Before I spend over $900 with tax at the stealer my mechanic will look over the car soon to see what he can find. Moosehead told me that the ignition switch goes bad on the E39 but I was told that the switch was fine. What else besides the cluster could be the problem .
