No turbo until 2500rpm and random limp mode with no warning light

Bought a 2008 bravo 1.9 multijet sport three weeks ago with 45000 miles on the clock. I've been back and forth with the garage ever since!

The main problem which they can't seem to sort is how after a week the turbo stopped boosting at 1750 and now boosts at 2500 or higher if at all. It's gone really sluggish and drives like a non turbo diesel. It has been into 'limp mode' a few times where it wont rev to more than 2500rpm but no engine management light.

Diagnostics flagged up a faulty MAF sensor which was replaced but the problem remains.

Anyone had similar problems?

Ouch, I thought the turbo kicked in at around 2500? Or is that different on the Tjet models?

Re: No turbo until 2500rpm and random limp mode with no warning light

thought I'd do an update... Problem still persists! Been back again where they found another error code. This time it was a faulty brake sensor and "airflow" according to the garage. They said the electrical fault can cause the ecu to do unusual things with the power output.

Admittedly it does drive better now but still doesn't pickup when it should and blips at 2500rpm. 6th gear just won't go at all..

Tempted to take it to a rolling road and get the garage to pay the bill as they seem clueless.
