Jaguar XF 3.0 D MAF Sensor and Throttle Body Clean ( Still No Luck ) 

Take a look at the crankbreather pipe they are flimsy plastic and because only a 4m hole and covered in the plastic hose protector you don't see leeks. Mine were broken both. Sides of the t joint and when I removed from each manifolds they just disintegrated

Inlet manifold or turbo actuator. Hope you get it sorted.

Tried swapping the MAF's over to see if the problem shifts to the other bank? Also, had something similar regarding the "circuit B" range on my 2.7 which I sorted by running some EGR cleaner directly through the intake (Wynns).... worth a try maybe?

You need to smoke test the inlet system. Sounds very much like the inlet manifold is cracked on bank 1. Those fault codes are common for that failure. Smoke test will prove. Good luck.

There was none of this with the old cars nowadays there is censors on everything nightmare well done though for trying 👍👍👍👍

Hi Jeff

cracked inlet manifold ?

Hi Jeff, Gutted mate, That's modern diesels for you all these sensors, filters more trouble than they worth and diesels don't like short runs the clog up easy, my brother has a Vauxhall Insignia CDTI all he does is a 7 mile trip to work and back home anther 7 miles it not enough for a diesel engine you need to do 20-25 mile trip to benefit having a diesel car. About 20 years ago the UK government were advising the public to by a diesel car saying they are cheap to run but what they were not telling the public they don't like short runs. years a go a neighbour bought a VW Polo TDI diesel all she was doing was 3/4 of a mile trip to the local shops and twice a week going in to Wrexham which is less than 4 miles away and with in 6-8 month all engine lights on the dash and then she was tolled that a diesel car was not suited for her, she never had this trouble before with petrol cars, she wen't back to petrol and bought a Nissan Micra 1.2 no bother at all. I hope things get sorted out with the farther in laws Jaguar, I bet you can't wait to get back on your bikes again that smell of petrol and two stroke oil,. As always a great video Take care mate
