hiiiiiiiiiii, I found the filter, its actually in the bolt what you take off, I didnt expect that, well give it a good clean and put back in, put the cleaner in the fuel, started and got upto temp but em light still came on and was still abiot cloggy and smoky, then took filter off and swapped diesel for the diesel magic (injector cleaner) and have left it so fingers crossed, if not cured by tomorrow I will change the needle lift injector its self and hope that works, if not im out of ideas??????????????

The camshaft sensor feeds the engine managements system with signals informing the system the position of the crankshaft, thus enabling it to calculate the injector timing.

The needle lift sensor sends back a signal when the injector is actually actuated, so that the timing can be find tuned.

If the crank shaft sensor is faulty, then engine will generally not run at all.

If the needle lift sensor is faulty, the engine will run in 'limp mode' - severely governed.

The needle lift sensor is inside no 1 injector, and is a small needle that is pushed through a small coil giving a signal when the needle lifts.

We have managed to remove the coil from the injector, and in some cases, managed to solder back the wire that comes loose from the coil, but sometimes the break happens in the coil itself. Of the 4 repairs that we have done, one 1 has been successful in the long run, so far.

Replacing the No 1 injector, which includes the needle lift sensor, as it is only sold in one piece, which in this case is understandable as it is quite difficult to remove and replace, is probably the best solution, though it is prohibitevely expensive.

I do believe that this is only with system fitted with a Bosch Pump/injector system.

Check the impedence of the coil by putting a multimeter on the two wires that run from the injector. If it's not about 100 Ohms, then there is almost certainly a problem with the sensor.
