2003 - TDCi Turbo Failure - Flycog
Hi a mate at work his Mondeo tdci lost power with EML on. Took it to Ford garage. New turbo sir £1000. He took car home and sourced a new turbo for £500, fitted and all's well. On investigation it seems its the vane control stepper motor thats at fault, a little box bolted on to the turbo that talks to the main ECU and operates the intenal boost vanes via a stepper motor and a linkage. You can't buy this seperate as Garret say that it has to be set up to the turbo !!!! Just seems a waste of a good turbo and money. Another reason not to by a diesel though i love driving them. You lads in the trade is this a common fault ?. Regards

Not in the trade, not heard of this on a Mondeo, interesting to note that not all Mondeos have the ECU controlled VV, IIRC Euro III cars have vacuum variable vane and Euro IV the ECU controlled VV.

Also reassure him - £500 is only a cambelt change on many cars and he does not have to worry about that cost.

It's an unbelievably stupid idea to mount a stepper motor on a turbocharger. The vacuum control device is dead simple and you can test it by mouth suction. VAG have been using them for years. It sounds as though the Garrett rep bought the guys from Ford a few good lunches - see Garrett website for details of their crazy electronic system.

659.

Nowhere near as daft as running unit injector pumps off a belt driven camshaft.
