2.0 HDI power delivery problem

I agree with Steve on this. Both petrol and diesels have lots of electronic engine management stuff and I would be hard pressed to say which was likely to cause less problems.
Going back to the original topic, I to would go with the MAF, but similar issues could point to the TPS, throttle position sensor, as well. Had both go on my latest HDI 110, and the symptoms are very similar or even indistinguishable. But I did manage to clean the tps, which has cured that so far. As far as I'm aware, all you can do with a faulty maf is to bin it and fit a new one. My new maf came from a guy on ebay with a 99% approval and it's been fine so far, which is about 2 years.
