What car did you do the swap in?

Make sure you have the 325i coding plug in your cluster. Part number should end in 468.

Low redline can be a VSS signal issue.

I will remove cluster tonight to check it out.

Is the cluster came from a 318, it would have the 7000rpm tach, but read wrong. It was my problem when I did my swap.

And 6200 is usually where it cuts out for no VSS.

OK, how can I fix it?

Make sure the DME is getting the VSS (vehicle speed signal). Should just be a wire you connect to the c101.
