A few weeks ago my instrument panel on my 2004 e61 stopped working properly, the only thing that worked were the two small screens in the middle so I opened it to check what was wrong and then there was a path in the circuit board that had blown on the way in/out from the processor, so I ordered a new one. It arrived in the post today so I installed The new one and everything worked fine the first drive, but on the second drive it was broken and only the two small screens in the middle worked. Has anyone experienced this before or know what could be the cause?
When the car is moving either speed, rpm, fuel efficiency etc does not work and the two small screens are much brighter than they should be
