I've spoken to Sarah today. I purchased a non-runner with suspected SKREEM issue. They said they could do it and I'm in the UK but at the moment my keyfob don't work and after the removal of the SKREEM they have advised the keyfobs possibly wouldnt be able to be synced. And asked me to check for other problems first. So at the moment I have my ECM/SKREEM/Halo antenna/BCM/RCM and fusbox relay module out of the car. I've cleaned everything down and am going to put back into the car, I've done the negative mod to the bell house and one to the body pickup point. I've change my camshaft sensor, crank sensor is currently snapped off and I'm waiting for a slide hammer for that. So in no rush and willing to participate in shipping this potentially dead unit which looks like it's been opened before to someone with the knowledge to do some can sniffing or soldering etc.. as long as they backup the chips hex files first.

The digital chaos forum is a good read if you search the eeprom and or the Bosch ECU number. They share dumps and have guys who can virgin most immo's and ECU's.
