Hi All, My 2003 m4 [ LM53VVZ ] has a faulty gm5 module and I can't find a used replacement with numbers that match those on the label on my faulty one.
My main concern is to have software program compatibility , can anyone enlighten me on the significance of these numbers relevancy.
Regards

What are your issues, there is a guy who refurbs your original on Ebay. Really cheap. Mine has been great
Hi, Thanks for that. Will now send it off on your recommendation. Price is very reasonable and on the premise that if it looks to good to be true it can't be true I hesitated .
I'm 82 and love driving this car with the top down, i'me a long life petrol-head not being my age perhaps!
Reactions and eye sight still good so why not eh.

It rules it out, comes with a lifetime guarantee and the relays fail anyway.

It’s not the biggest risk you will take in life & easier to remove than door latches as a starting point
