Anyone experienced this, around 3k and 4k I just lose all power (it's like you've let off throttle)

I'm this video I had foot flat to the floor. I also have hurendous mpg.

Car only has one error code which is dpf pressure sensor open circuit, I've robed dpf to check and it is not blocked (infsct very clean but intact)

I took exhaust system off completely and ran just a down pipe and the issue persists...

I'd suggest an overboost fault possibly - but it would normally flag an error - has the car had any modifications, remaps etc?

Thank you, sorry for the late reply I forgot my login details!!

I too thought overboost but I got it on MES and it seems to show boost is within spec.

The car is 100% stock

Perhaps it's regenerating all the time. The only fault you have is the dpf pressure sensor. If the ECU thinks the dpf is blocked it'll try to run a regen. Perhaps that's why your fuel economy is so poor?

That's a new one on me! Another convincing argument for their removal!
