A few weeks back I posted about black smoke on acceleration, poor MPG, badly sooted rear and intermittent stumble on idle. Miles on motor are 67k. I booked the car in to Motech @ Christchurch Dorset, last week, they had it yesterday. Their findings are 8 faults 7 for intake manifold and 1 for DPF. They cleared faults and all came back except for DPF. Stripped out the manifold today and said the motor which controls the swirls flaps Isn't working and a couple of pipes leading to EGR are blocked along with a couple more issues within manifold. Also there is a boost leak. A quote of £1200 to sort everything out. I've given permission to go ahead with the work. Really hoping this will be the end of this issue at last. Having just spent £500 ish on having the plugs and plug control unit changed just before Xmas.
