CX5 2.2l Diesel - 2015 Lack of Power

(1/1)

Goat Eyes:
Hi, any help appreciated. Mazda CX5 2.2l Diesel, 2015.

Lack of power and flat through all gears, won’t rev over 3500rpm, turbo doesn’t come in. If I rev it hard it chucks out loads of white smoke.

Have used a DPF cleaner and done a forced regen.

Replaced the MAF sensor and will be getting a MAP next week, which I’ve had out and was full of carbon. Might get the inlet manifold off before that comes too and give it a bit of a clean.

DTCs are for SCBS and MAF. They clear then come back from time to time. SCBS System Malfunction is fairly constant.

Any known faults or anyone had anything similar?
