Hi guys.

I'm a little out on a limb here in the e63 forum, i usually float about in the slightly more inexpensive e39 forums LOL!

Anyway, i hope you guys don't mind but i have a question, and its about a 645i as opposed to the M6, but i think the "answer" will be the same anyways.

I would like to have the DME flashed with the latest software on a 2004 645i due to some niggles i want to rule out as DME software issues. I have had one dealer tell me the DME must be replaced as the early models can't be reflashed.

True or BS??????

On my E39 M5, if I remember correctly, the DME can be reflashed a maximum of 4 times.
After that - DME will no longer accept any updates.

Sorry but I am not familar with a 2004 6 series.
My beast is a 2006 M6 and my DME has been reflashed twice already.

I would call around other BMW dealerships around you if I were you to confirm for sure what the 1st dealership told you.
