BogMonster Posted September 2, 2010 Share Posted September 2, 2010 The turbo could be at fault but it could also be the boost compensator in the injection pump, this adds fuel when the turbo comes on boost and the diaphragm inside it tends to seize up. Also the pipe between the turbo and the diaphragm can come adrift or chafe through, which means no boost to the pump which means no fuel which means no power. Also check the turbo hoses haven't collapsed internally especially the little 90 degree one just coming out of the turbo as this is a common problem.

davek0974 Posted September 3, 2010 Share Posted September 3, 2010 I've also recently got a m-reg 300tdi, it had the same fault too. It turned out the turbo was buggered It drove ok and very economical but as you said, useless at hills! I only found the fault by fitting a boost gauge which showed zero boost. A 2nd hand turbo fixed the boost and gave more power but i think there is still a lingering fuel issue too, i'm leaving that for a while as i need to use the motor.

big fish Posted September 5, 2010 Share Posted September 5, 2010 Hi I have the very same problem with engine power, driving the disco on its own it's not to bad, as like today coming down the M1 towing my caravan ( 24 foot twin axle ) as i hit a hill i have to drop down the gears ,may be down to 3RD on some, and at the same time the engine temp rises quite high, and when on the flat its OK but no real power. someone has said if may be the timing. filters oil and air new lift pump changed sedementor bypass, and checked all the above. thanks Martin Quote Link to comment Share on other sites More sharing options...
