My last car was an R230 SL500. Driving home one day, the ABC warning came up on the dash, coinciding with an apparent loss of damping. Took it to the local MB dealer. They messed about for a day, then called to say a strut had failed. OK, told them to proceed - Kerching, £1200 for a strut. Went to collect that night, embarrassed faces all round, it had failed the rodeo test. Next day, they call to say it has to be the valve block. Kerching, another £1200. Called the next day - still failing. Er, yes, it could mean the strut was ok, but we broke it removing. MB said they needed a new transponder, but they knew they had screwed up, so that wasn't going to be charged for. Swapped that over (now off the road for a week) - called to say it was still faulting.
I reminded them of what I said when I took it in - the ABC fault coincided with a high pitched buzz on the radio that varied going over bumps - in my humble view, this was electrical. They took another day, then called to say it was fixed. In answer to the inevitable from me - the fault was a broken wire (although not obvious) from the original strut.
Real cost to fix should have been about £20.00. We "did a deal" re the accumulated £2,500 odd & the dealer owes me some points (to not name & shame!!) - at least they now listen when I offer details of a problem. (they might not pay any attention, but they listen!!).
Advances in technology do call for ever more sophisticated diagnostic systems, but more often than not the diagnostics diagnose the symptom, not necessarily the cause which is where intellegence should come into play - particularly at £100/hour.
I have to wonder how many unsuspecting, trusting but mechanically uninformed customers end up paying HUGE amounts to main dealers when the dealer has simply started at the obvious end of a system, happily replacing modules one by one (few of which ever get taken off again) until the fault goes away.
