Thats what you find with a lot of US series, they start off looking impressive then are so long winded and wordy (like this post) that in the end you forget what it,s all about.
In answer to Fat Shadow, my airbag light has been on for about four years,(covered it with ins.tape). Due to change on MOT regs its now a failure as we all know now.I,m no mechanic so the guy who does it all for me says leave it till nearer MOT time (Aug) and go from there.Also may not be ecu anyway but i thought i would ask anyway. Hope this all makes sense.
