Hi....as the title says........ it was driving fine yesterday .....but when I was nearly home I noticed a lack of power and she was holding onto gears for rather longer. This morning she was like that that from the off....feels like there is next to no boost at all. Before I have to go our (in the wife's A Class now!!) i had a quick look for lose hoses and vacuum pipes....nothing obvious but as you know its pretty packed under there!! The turbo vane actuator arm is working when I rev it....although I'm not sure how much it should move when revving in neutral. but at least it responds to the throttle. No obvious boost leak sounds when driving or revving and I can just here the turbo spooling up with the bonnet up and engine cover off. The only things that have happened recently is a new grille.....but I cant see anything that I might have knocked there....and also the PCV valve popped out of the batwing near the turbo exit.....now refitted and held in place with cable just to be sure....but the car ran fine after that. That's pretty much all the info I can give. P0299 (low turbo pressure) is the only fault found.....I reset it and so far its not come back....but still no boost so I'm sure it will return. Any info gratefully received....I've only had her a few weeks....not a great start after 5 years with no engine faults on a 175,000 mile ALFA!!!!
Thanks in advance.
