I would expect a MAF reading around 5g/s at idle with a hot engine. The egr not working properly or a dodgy maf will give different readings

I put in an EGR blanking plate to see if that was contributing to the problem, but it made no difference to the MAF readings (as I suppose you would expect). I'm going to see if I can visually inspect the hoses for leaks, but I'm not sure how...

Hijacking welcome! I have since replaced my EGR with a known working unit, and replaced my last two injectors in the same condition. My car still smokes black under load, and I am convinced my MAF readings are too high.... no one can tell me...

Good evening, all. I don't mean to hijack this thread, but I have a very similar issue here with my 2008 Freelander 2 TD4. I don't have any black smoke issues, and the car is well-serviced and otherwise seems to be running quite well for its...

The ECM doesn't learn values after a replacement is fitted, because it doesn't know a replacement is fitted, hence the need for an air path calibration. JLR, PSA and Ford all list an air path calibration as in integral part of work required when...
