To cut a long story short:
Bought car (W124 e300 td) about 6 months ago. About 2 months later it broke down with air in fuel lines. Replaced o-rings and filters and ran absolutely fine.
3,000 miles and three months later same thing happened again. Car went to garage as it broke down on the M6 and they replaced filters and o-rings. Car drove fine.
About 1,000 miles later and Thursday took car for its MOT. To pass it needed the long brake pipe replacing, the mechanic (Merc indie in Stoke) said that the fuel line next to it should be replaced as well as he would struggle to remove fuel line without brake line. He replaced them both (they are definitely new.)
Anyway, having only driven back from MOT, went to go out today. No power, smoke. Looked under the bonnet and air in fuel lines again. Will phone garage tomorrow. I assume that this is linked to the new fuel lines, but I can't see how it hasn't been done properly and the new line does not leak.
My question: could there be something else causing the air to keep coming into the fuel lines? Is keep replacing the filters and o-rings just fixing the symptoms and not the cause. Since the m6 break down the car has only been run on proper diesel.
I'm rapidly losing confidence in this car!
