hi everyone,
my 2002 tdi 130 has an air bag ecu fault, it was involved in a minor bump and the steering wheel airbag deployed. all repairs have been done but the air bag ecu is frazzled I guess?! has anyone had theirs replaced and how much did it cost? I'm aware that its an mot failure these days so it's going to have to be done but I'd like to have some idea of costs before I start getting quotes.

ive seen, on the Internet, a gizmo that erases crash data, etc. is that a safe/viable option?
this is the one http://www.budgetdiagnostics.co.uk/t...ag-reset-tool/


any help is much appreciated, thanks
