I see that you have a big knowledge of gauges and coding plugs...
I have a question for you...
I have a "brand new from dealer" without code BMW Z3///M S54 cluster. I want to hook up it in my 318is. I've tried a bit of things on it:
- Z3///M cluster fitted with Z3///M coding plug (not coded). It shows "CODE-" when I turn the key and gauges not work...
- Z3///M cluster fitted with 318is coding plug. It shows "Code 2". Gauges aren't working.
- Now I have the front part (faces, chrome rings, needles, glass) of Z3///M cluster fitted to rear 318is electronics. Readings are wrong (scales are differents), but I know how much are off.
I've tested to enter to the secret menu and it is structurated as E46 (
link), there is the structure, but there aren't infos like VIN and other...
What can do without take it to the dealer?
If I find an used coding plug from a Z3///M with lower miles, it should work except of rpms, right?
thank you and great infos
bye
