Ive just rung BBA Reman. They do cluster repairs for PATS problems. I need to send them the instrument panel, the PCM and one key and they will test it all for 35 pounds. A unit repair (assuming required) is 115 pounds. They seem professional and know what they need to do! its a 3 to 5 day turnaround though. Anyway, I'm gong to recommend this to my friend as the way to go! I'll update this post with the results.
