Hi, My 2002 tddi is suffering from a random drop in power. If I turn engine off then restart it's ok for a while. There is no smoke, no flashing glow plug light, no strange noises. It runs and drives reasonable, just as if there is no turbo.

I've had this before on another focus and was just an air leak on the maf sensor pipe.
I've checked all my pipes on the intercooler circuit, can't find anything.

I have a 'donor' car for spares in the garden so I've swapped the maf sensor & the EGR solenoid & intercooler sensor. Still the same.


Any suggestions?

Regards, Dawson
