I should like to hear from anyone who has suffered from this problem.
Firstly, note this sequence of events.
1. The SRS warning light appears.
2. The specialist servicing company I normally use cannot diagnose the
3. MB dealer cannot diagnose the fault.
4. The specialist servicing company tries numerous manual checks over a
4-day period, including air bag test, seat belt checks and changing over the
control unit. They are reluctantly forced to admit defeat.
By now, I have discovered that my SRS problem is not uncommon. Similar
reports about ABS warning lights have also emerged, but are supposedly
easier to remedy.
I telephoned MB Customer Services Complaints (Europe) to ask how they can
allow such a 'known problem' to exist and what can be done about it. Their
reply was astounding. Basically, they refused to accept any liability for
the fact that the
software in the car will not 'speak' to the diagnostic program. I explained
to them that this must be a software design flaw. They flatly denied my
Regarding the SRS fault, they advised me to take it back to the MB dealer.
I explained that the MB dealer cannot provide me with an estimate of the
cost involved and that I am not prepared to write the dealer a blank cheque
for a 9-year old car. MB then offered to consider a 'goodwill application'
from the dealer.
I, therefore, went back to the MB dealer, whose Service Manager I know quite
well. (I should explain that I used to have my car serviced by them until
their labour rate hit UKP 77.00 per hour + 17.5% Value Added Tax). He
warned me that MB hasn't the slightest intention of accepting a goodwill
application (i.e. a partial or complete refund of the costs involved) on a
9-year old car. Regrettably, he still cannot price the work involved,
because he has no idea how long it will take to find the fault (neither have
MB Technical Services, Europe).
If this matter remains unresolved, I shall be left with a permanently lit
SRS light. Although this won't affect the drivability of the car, the air
bag will remain deactivated and this fact will automatically reduce the
residual value of the vehicle.
