Hi all, hoping someone can give me some advice please.

I have a 2005 Jaguar X-type 2.0d Classic with 82k miles, I recently had a cutting out problem when accelerating and also a cold start problem. Local jag specialist replaced the 4 injectors, coded the new injectors and also replaced the intercooler hose, fuel pump, fuel filter and fuel regulator valve. 2 weeks later I had the DMF Clutch and starter motor replaced and I also had a full service done and the car drove great and didn't cut again.

But the past 5 days there as been a tapping noise coming from the engine when accelerating and then the past 2 days when I have accelerated to over take the glow plug light starts to flash and then the engine cuts out. pull over turn, the key and it starts straight up and drives fine until I try to accelerate hard again and then glow plug lights starts to flash again and the engine cuts. I have checked for fault codes but there is none showing

What could be wrong ?

it could be the crankcase sensor

not sure what turbo you have?  as the diesel has a actuator ! one is mechanical and the other is a square box which has electric circuit board and cogs inside.  you can search in xtype forum,  which is where there is loads of help on this issue.  plus there is also a picture of how each one looks when you search in the forums,
