I will go ahead and install the M3 cluster from the donor car. As was stated earlier, if I had kept the original 318ti cluster (which had aprox 150K miles) and added the S52 engine/ECU (which had aprox 77K miles), that would’ve activated the TMU light. What would the odometer reading be? 150K or 77K?
Also, what happens when I sell the car? Will there be a discrepancy on the paperwork?
Now I have a different question.
How do I remove the hose/valve from the booster? This is from the donor car and I will need the hose and valve.
Thanks again for all your help.
