    Help with my Tach problem.

    I did a swap in my 91 318i last year, m50tu and before the swap my tach worked fine, after i did the swap it didn't work at all. Was at the bottom of my priority list for awhile but last week i hit a bump and it started working, except its off a couple 1000 rpms. the needle sits at Zero when its off but when its idling it says its at around 3k when its clearly idling normal. Any idea?

    you need to change the code plug in your tacho. you had a 4 cylinder engine and swapped it to a 6. you need a plug out of a 6 cylinder e30.
    white plug on the right bottom corner under the water temp gauge behind the plastic cover.

      That. And if its intermittent, the batteries may need a change
