I have 2.2. 136 and it starts beautifully, I know that doesn't help you but I also have a 2.0. 110 Hdi that doesn't, its been getting progressively more difficult, it will eventually start from cold but when warm is almost impossible, I think this is due to a worn HP diesel pump, but if yours starts OK when warm its unlikely to be the pump.

How fast does it turn over? Hdi's need a good battery and starter. Does it have a fuel primer, if so pump it until hard before you try to start, if it starts then you have an air leak in the fuel system.

It depends whether it has a Bosch or Delphi fuel system, if it has an in tank pump it probably won't have a primer. The Bosch has one should be able to hear it run for a second or two when you turn the ignition on, if you don't, either it hasn't got one or its faulty.

The only way you will be able to see diesel leaking out if if you park it on a steep downward slope with the tank above the engine. As it has a primer there will probably be no in tank pump so the fuel is drawn up by the HP pump, that makes the fuel line under vacuum so air will be drawn in rather the fuel leaking out.

Check the injector leak off pipes, its possible air could be getting in there, also make sure the fuel filter is seated and tight.

Hi, have managed to change fuel filter today, after intially looking ok and taking out for a test drive, I then parked the car up (on a slight uphill slope, engine slighly higher than the tank) and went back to look at it 4 hours later, there was a small amount of air in the pipe between the filter and the engine pump and when I started her again quite a lot of air reappeared and more when I revved it. Any ideas on where the air is likely to be getting in. When I use the primer pump it obviously goes quite hard after a few pumps however when checking a few minutes later it has gone soft, is this normal or would this indicate a leak bwtween the tank and the primer bulb? also any ideas on where there would be any non-return valves?

Thanks

Hi holmesdaren

I have exactly the same car and exactly the same problem, I've been trying to sort the problem out for months now and I just can't fix it, I checked:

• ECU (No Errors)
• Injectors (Leak off test - Everything OK, Corrections/Doses - OK)
• Looked for leaks (Can't find any)
• Replaced the Leak Off connectors (No change)
• Replaced the fuel filter (No change - Maybe starting a little bit better but maybe it's just my imagination)
• There's no vacuum/pressure noise when you open the fuel cap

Can you please tell me what you did to fix your car, normally I always fix my car on my own but this time I'm desperated and also no car mechanic can help me :(

Pretty much everything's been checked but the car is still not starting properly, the glow plugs are fne and the temperature outside doesn't make any difference. The only thing that makes a difference in my opinion is the amount of fuel in the tank, I have the worst problem starting her when the tank is half full. I'm running out of ideas already :(
