Well, I asked our son, but ... Houston, we have a problem.

The problem is that the shop where they fixed his car is in Ukraine (he lives there). So they told him what the problem was, in Ukrainian. It was impossible for him to translate that either to Greek (he doesn't know any technical terms in Greek) or to English (his English are not that good either).

So the best I can say is that there should be some air mass sensor after the air filter and before the intake manifold, and it was that sensor that was clogged by the exhaust gases.

Sorry if I built up your expectations for nothing, but that's the best I managed to figure out from him. I know that they changed that sensor and his X5 is just fine.
