I'd like to hear from anyone who can shed any light on this problem.
When my SRS warning light came on, I took it straight to the specialist I
use for servicing. Unfortunately, their diagnostic equipment failed to
communicate with the car, leaving them unable to determine exactly where the
fault lay. They made a second attempt using a more 'hands-on' approach, but
it continued to mystify them.
Finally, they suggested taking it to an MB dealership to see if they could
diagnose the problem. When I did so the car also refused to 'speak' to the
dealer's diagnostic software.
So, three visits to two garages and I'm back to square one, although I've no
complaints about the efforts everyone has made to resolve this issue,
especially since it hasn't cost me anything yet, other than my time.
The MB dealer suggested swapping out parts in order to eliminate the
'offender' but, at £77.00 per hour for labour, you can understand why I
wasn't all that keen! The major item in question here is the control unit.
If that has blown, then I'm looking at serious money (circa £800 for the MB
dealer to replace it).
Fortunately, the failure by the MB dealer to identify the problem has
breathed new determination into the specialist servicing garage and they
have asked for another crack at the problem. For one thing, they intend to
swap my control unit with one from an old 300D and, if that doesn't work,
they appear to have a few more ideas up their sleeve.
If anyone has faced this problem, I'd be grateful for some practical
