Has any one had this before.

its on a 2002 mondeo 2.0 tdci 130

the car has lost power and smokes like a trooper.

it misses bably too.

This is what the fault finder found:

P1344 Pedal Demand Sensor C Circuit Range/Performance (see 2131)

U1900 CAN Communication Bus Fault - Receive Error

P2339 Cylinder #4 Above Knock Threshold.

any ideas peeps.

are you using the right scanner for a pre 2004 diesel as the u1900 code suggests that the codes could be misleading?

It sounds like you've blown a gasket, valve stem seal or a piston ring.

I'd get the cylinder head checked as it really sounds like oil is getting in.

What colour is the smoke? Black would mean unburnt diesel whick would basically loss of compression on one or more cylinders, blue would be burning oil.

White is either steam or smoke depending on if it smells of fuel or not.

Have a read of these sites for better info.-

the smoke is unburnt diesel, had it started earlier and lots of grey smoke and a bit of black too, think its a injector down..??
