3-Series (E21, E30)Chat relating to the BMW 3-Series from 1975-1983 and 1984-1991 line. Specific models: BMW 315, BMW 316, BMW 318, BMW 318i, BMW 320/4, BMW 320i, BMW 320/6, BMW 323i, BMW 320i. E30 Family models include: BMW 325e, BMW 325i, BMW 325is, BMW 325ix.
Quick question, with this 86 325 I just acquired, the tach will periodically jump to 2K and sit there for a while, eventually to return to normal operation and repeat the cycle. I assume it's communicating some kind of fault code? I know fault codes are normally communicated though the check engine light, but does the tach also display some soft of diag codes too? And yes, the check engine light is on, as it was when I bought it (will reset it and read codes off it soon).
So, it's the ICV, even if this is happening while I'm driving on the freeway the engine is well above 2000rpm? Because that's what it's doing. I can go from idle and accelerate and shift through all the gears, and during that whole time, it's sat at exactly 2000rpm. Does that still sound like the ICV?
ohhhhhhhhhhhhhhhhhhhhhhhhhhh my bad ghead i thought you were saying at IDLE...haha durrr...no its very common for e30's to have gauge cluster issues..they like to give you a hard time...im not sure on the procedure for repairing it but mine did that to id just know on it and it would kick back on...you may just want to check all the connections...but im guessing its internal..
