Many years ago i had a similar problem with a car which turned out to be, wait for this, A sweet wrapper in the fuel tank !! and intermittently would block the fuel outlet. When the car had been stopped it floated free and then the car would start again, only to occur again at some random time, sometimes once a month, sometimes twice a day... Just an off the wall Idea which it may well be, a blockage...

Hope you find the problem, i know it drove me mad..

Or try looking at the fuel filter and see if it has the rubber gasket where the fuel filter screws onto the fuel filter housing (there should be two one large and one small)-when you take the fuel filter off you have to unscrew it from the housing attached to the bulkhead once you've unscrewed it look at the top centre of fuel filter-in the middle when you look at it from the top of the filter there should be what looks like a rubber ring attached to the centre hole if this is not there then check where it screws onto the housing on the threaded part if it's not there that will cause an air leak into the fuel system

lol sweet wrapper thats very unlucky but i will have to take the tank off and have a look when she is almost empty i thinks many thanks discofan

No need if i remember right. There should be a round panel that unscrews from the boot floor & you can then lift out the fuel pick up from the tank & inspect it.

At least I'm sure that was right on the 200Tdi I used to have.

I have heard of fuel lines up near the tank rotting away & causing airleaks into the fuel. They never seem to leak due to the suction so hard to find.

Hi, If you've ruled out the fuel system being air locked then i think it could be the spider going faulty, this will throw in the immobliser randomly, all you can do is wait? If these are the symptoms then look there.

I hope it helps
