Well, another update. I found a piece of damaged tubing that connects the charge air piping to the air doser. It's just a small piece that has white writing on it and sits above the oil dipstick between the hard plastic pipe above the turbo and the doser/throttle body. The garage replaced this but still no joy.

This is actually getting hilarious now as I can gun the rpms up to 4000 and the car accelerates like a heavy brick. Nevertheless, despite the humour, it's going in tomorrow for another round of inspection. I changed the air filter and still no joy, but the engine sounds really loud. I can smell a faint post-cat exhaust smell around the turbo so I'm wondering if I haven't got a small exhaust leak and one of the O2 sensors is causing a lean condition. Lots of fuel, but no power perhaps?

I think I'll also have them inspect the charge air piping down under the engine in the area of the intercooler. Damn, this is frustrating; it's been almost 1 year that I've been chasing this with no solution.

Will post an update if I have new information.

How would the crank speed sensor lead to power loss?

Sigh. Came back from the garage.

They reseated the air filter (even though I already did it), scanned for codes, inspected the emissions control unit, looked at the charge air piping and intercooler. Nothing.

I don't know. The car sounds loud like it's got a modified exhaust and it hasn't got much acceleration power, but nothing is showing as being wrong.

Guess I'm at a dead end.

hmm :-( I know how you feel, am just glad it's not my car because after oh 3 months of ownership it would be down the road, never known a car to have such a silly fault that you or the stealers can't fix :-/ shocking....... epic fail :-(

Threw in some diesel injector cleaner and bought some MAF cleaner as well. So far the car runs smoother with the injector cleaner in there but it's still lacking power. Will clean the MAF this weekend and see how it goes.
