Customer Question

I have a 1988 BMW 325i and I am experiencing issues with my cluster. The speedometer is off a good deal and my gas gauge is off as well. My MPG gauge is also not working. Will a new SI board solve these issues or should I go another route?

My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If the speedometer and gas gauge issue started to occur at the same time but the vehicle runs and operates properly I don't suspect this is any sensor issue here causing this fault as this sounds more like a fault with the instrument cluster board itself needing removed and repaired or replaced.I have seen the instrument clusters fail or act up in the past before needing repaired or replaced for issues like this here.I would have this tested further to see if this is the cause for sure here and then corrected from there.

Thanks Pete
