Hi all
I am new to the forum but not new to repairing. I recently puchased a wrecked 08 550i and had to replace driver airbag so I purchased an OPPS system and was able to use the DIs and check the trouble codes and clear some. However when i went to SSS it connected and told me I need to update a bunch of contols before I can begin, so I did and BAM, it my car will no longer turn over and and it keeps telling me i need to change my DME control. I since puchased a junk one and waiting for it to arrive what can i do? when i go into SSS it tells me i have (1) more chane to program my DME but it wont allow me to do it! Car wont start and I need some advice on clearing airbag code ande if there is any suggestions will be appreciated thanks in advance
