Intermittent "No Crank" issue. EWS Delete?

Hello. I have been trying to diagnose and repair a problem with my son's 1999 328i for... well forever. I did all kinds of diagnostics and have concluded that the problem is in the EWS, or at least the communication of the EWS to the DME.

Given that... my question is does anyone know the best way to do a EWS delete on these cars. The DME is a MS42. I could replace the EWS, but I'm not sure what I would need to do a recode (if that's the right term). I understand that if I went to a dealer, the EWS replacement is fairly inexpensive but that they can have trouble with the new EWS4 and the older DME and then want to replace the DME.

Any suggestions or information would be greatly appreciated.

Going to the dealer will cost you a lot but this is the correct way. Second option to saves money is to buy the DME, EWS and key chip, it might cost at least $200.00 May I ask if you don't mine, why you concluded that you need a new EWS? What's wrong with the car? Check this, try to by-pass the EWS.

I've done the bypass. Car will then crank but will not start. I could list everything I've done but trust me... It's definitely an EWS issue. Dealer is not "my" option. There are several places to get a EWS delete done. I'm trying to see if it's something I can learn to do. I like learning about these cars... since I own a couple of them. But, with a lack of any help... I'll send it off and have it done. Thanks for the response.
