I'm just having a rant today against MB dealers, my local MB dealer (Southport, Merseyside) changed me £515.84 the other day for the privilege of getting my W140 S300TD starting again.
They also wanted another £100 for a new battery, which had only been replaced 2 months ago. Fortunately they have fitted a new battery under the MB warranty.
The annoying thing is, the car was supposed to have been fully serviced by a major MB dealer in Belgium about 14 months ago, the service book claims it was a full service so surley these filters should have been replaced?
Even the air filter is way older than 14 months so it looks like that hasn’t been changed either.
The car wouldn’t start and I knew the glow plugs were already new as I had them replaced about 6 months ago (not by MB), so I suspected the fuel wasn’t getting through to the engine.
Sure enough after removing the main diesel filter and pre-filter they were all blocked up, it looks like they hadn’t been changed since the car was new never-mind 14 months ago, changing these however didn’t fix the problem as expected.
After a phone call to MB in Belgium they came up with 2 possible causes;
I didn’t like the look of taking all the air-intake off myself so phoned MB, they sent out a tow truck to pick the car up; had the car for 2 days then fixed it.
Sub Contracted Tow Truck £85
Parts £54.46 (all fuel lines and filters)
Labour £299.55
VAT £76.83
Total £515.84
I was told that because the filters were blocked it had put pressure on the fuel intake causing a leak at the seal and could have been avoided by paying a few pounds for the filters.
And the moral of this story is; never trust MB if they say they have serviced the car double check it yourself.

After a phone call to MB in Belgium they came up with 2 possible causes;
- The alarm immobiliser was cutting off the fuel.
- There was air in the fuel causing loss of pressure.
