I am thinking about putting M3 clocks into my 328i so that I lose the MPG guage and gain the Oil temp one.
I have read up about fitting the oil temp sensor and wiring etc but I am confused when it comes to swapping clocks.
My 328 is on 97k and the clocks are considerably higher than this.
How do I get my mileage and service light to work on the M3 clocks?
I have read somewhere that there is a chip that you can unplug and swap to make it change but can anyone confirm this?
