Thank you for posting a detailed step-by-step instruction. I drive a 2007 328i Coupe. I have been getting the dreaded error codes since January of 2011. I took it to the dealership. They quoted $1096 to replace and program the SZL cluster. I was not willing to pay that kinda money. I took it to two independent bmw shops, and they both said that they could replace it but but I will need to go back to the stealership to program the new module. Then I came across this wonderful post. I pretty much followed the instructions and it worked like a charm. However, I did not have to solder or reline the PCB. It looked brand new (even under a magnifying glass). I decided not to touch it, but went ahead and cleaned the optical disk using alcohol and put everything back. It has been over a month since I did this, and I have not seen those dreaded symbols on my dashboard. I can't thank enough the original poster. I really appreciate your kindness in sharing this fix.
