anyone interested in a GB for the 540i/6 EWS chip?

[Jehu]

I'm in the '95 540i/6 club as well - build date 9/'94, but the dealership told me (just today) that mine is a weird animal - that BMW started putting in the EWS-II systems in some E34s at that time. (Consequently, a new ignition key will cost me around $200.) I'll be able to pull my DME tomorrow to make sure of the number and the chip I'll need.

EDIT: I pulled my DME today and found that it is a "404". Does this mean that I absolutely do NOT have EWSII? I have an EWSII key fob, but no other keys. Is there something else I can confirm visually - like in the ignition switch?

Still searching the archives. I still want a Mark D chip, nonetheless...

Does your key look like this? If not in such rough shape...

My leather key fob has a silver Texas star on it, but...

Yeah. Same key head. I'm feelin' that BMW stuffed the EWSII chip into my 404 DME without changing to the 484 designation. I've emailed Mark D to see what he can tell me about it, but I haven't opened up my DME yet.

Here's a pic of one of the DME stickers with BMWs hand-written "updates". Can anyone decipher it?

I think the numbers read:
G A 6423
427258
1 744 505
142953

With the updated EPROM numbers (1 744 505), does this mean that they DID change the block to Alusil? Why else was there an EPROM update?

Hi Mark - Is this GB active?

I didn't get much interest in it. Also, a few people that bought the chip had a CEL, even though the chip works well. I want to track that down before shipping any more. I haven't been aon here much since I arrived back from my trip to Vancouver as I've been busy with a contract that requires me to be at the customer's site during the day. I'm working on motion control systems for automobiles. I'll be working on prototypes that may appear in furure MY vehicles.
