how to resync bmw e90 dme and the ews with inpa

After putting all the original stuff back into the car, still no start. In the ecu box I went through all of the connectors, fuses and relays, replacing any water damaged relays and checking the rest for current passthrough. I wanted to start from scratch so I meticulously cleaned and inspected the original DME and checked for any damaged tracers. The dme had a high water mark about and inch from the bottom and some light damage to what looks like a small diode, a little blackening. In the trunk was the original dme, cas and key/tumbler. Whatever was causing the no crank condition was not fixed with the swap. When I bought the car it had a CAS DME Key swap done to it but I didn't run. It's been done on this forum before just can't remember the thread. You'll need a BDM rig but it's not that hard. I'm pretty sure you can virgin-ise the DME by clearing an area of RAM thus allow the DME to Resync to CASS. Two shots of cleaner and the fault has never come back My E89 has an occasional ghost code pop up on high throttle conditions and it turned out to be one dirty pin on the DME.

Pull the DME and check all of the connections, clean lean anything that looks corroded. If the DME is spitting codes, the CPU is running and it's probably not terminal. I have another donor DME to install but my understanding is that it needs the EWS disabled or it wont play nice with the CAS. The codes its spitting dont make much sense as to why it wont start and I have zero communication with the transmission. Car will not start and I think it's because of a water damaged DME. If anyone can help, I have communication with the car on a pc with Inpa and an internet connection. Now my mission is to sound ignorant anyway in hopes that someone reputable in these fourms, Hassmaschine possibly, would take pitty on me and my money to possibly perform an EWS delete remotely on my MSV70/2006 530i DME. I've been lurking through the threads for the last month trying to learn enough about my new car to avoid sounding ignorant.
