Hello, I have a 1998 R34 coupe and im having some weird problems. The other week i got in to drive it and when i unlocked it problems started, 1. The tacho and speedo dont work, 2. The bell chime for door didnt chime, 3. The interior light stays on, 4. The passenger door wont lock with the button on the remote or drivers side panel. It still starts and drives fine, I disconnected the battery and reset the ECU which worked, but then it happened again and again now that trick only works sometimes. Any ideas? Cheers
