My 320cdi is having issues starting... oddly enough it seems worse when hot but still struggles hot or cold. If I fill up with diesel after a motorway journey go in and pay, then return and start it, it can take 3 or 4 start cycles (auto turn over cycles) to fire.
Now, I've replaced the 6 low pressure line 'o' rings and the issue got a lot better but still didn't 100% cure it. It would fire after the first cycle but would still take 4 or 5 revolutions before firing.
1 issue I did have, was re-fitting the plate that holds the 2 pipes on the HP pump. The only 1 that had a plate to secure the pipes (torx bolt). Upon fitting it the small pointy part of the plate that goes over the outter most pipe, snapped!! It does however look at if it's holding the pipe fine seeing as the other pipe never had this extra part to it and it has the same amount of surface area pushing on it.
My question is, can I get a new plate? Or is it part of the HP fuel pump only?
I've changed the fuel filter and new o ring and also replaced the leak off pipe o rings too. Thinking either this plate is not clamping properly, brittle fuel pipe allowing air into system, HP pump up the swanny or duff injectors (which leads to another issue...).
I've also got a metallic rattle coming from the injector area. It happens after the engines warm and only on light throttle. As soon as boost comes in, the rattle disappears! It only does it under load too so difficult to pin point on my own. Could this be an injector giving up the ghost? I've had the air box and heat shield off to check the manifold for leaks and the turbo and catalyst. But no tell-tale soot marks!
