300 ES - SRS warning light don't go out. As this is in the MOT from Jan 12 I thought about getting it fixed. Paid an 'indipendant' 45 quid to interrogate the comp, he said no info comming from airbag ECU so that must be faulty. Replaced it with a second hand unit but no difference. Any ideas as to sorting this out without maxing out the visa on 45 quid plug-ins?
