Low turbo pressure on a GT
Hi, Hope someone can help me please. I have a 2006 1.9JTD GT. I've covered 121,000 miles most of them relatively trouble free. Its just developed a habit of 'cutting power' whilst driving hard (80/90mph in 5th, climbling up hills over the A66 in Cumbria)
The car is serviced and in all respects is very very good. It is looked after by a fully qualified Alfa mechanic privately. He has access to all the usual dealer equipment and under test it has said that there is low turbo pressure. When it goes into 'limp mode', if I pull in and stop, then switch back on, everything is fine again until I push it again under acceleration up hill. It cuts out again and so on.... Under normal driving (no hard acceleration) the car is fine. The warning notice reads "Motor Control System Failure". Any ideas as to the cause. Thanks.
