. #2. I'd say yes, go and remove the ASV, intake manifold and have them a good clean. Don't touch the EGR cooler though as they seem to be fragile on BRMs. Also, don't touch the gunk on the intake ports, at the place where manifold ends and head passages begin going to valves - leave that gunk alone.

Oilleaks. These are the most serious and typical problems for this unit, but that doesn't mean other issues aren't present, typical of many diesel engines, like malfunctions of the EGR valve

You can add a catch can (provent 200 is very popular) that will remove pretty much all of the oil from your crank breather. Maybeone of the clamps is broken, or a coupling hose is split, or the plastic housing on the intercooler is cracked, or there's a hole in the aluminum core, etc. You'll just have to clean it and see where the leak is. Used intercooler is $50-ish, or they're $150-ish new including a new MAP sensor (I think). Hi A warning popped-up today telling me that my oil had reached the minimum level. I pulled over and topped-up (she's done 165k, so it makes sense to carry some oil, although I've never needed it before!) Having done this, the warning light went off. Shortly afterwards, there was a strong smell of burning oil. MembershipNo: 1379. Location: Durbanville. Re: Polo tdi intake cleaning and EGR valve. by kripstoe » Wed Jun 01, 2011 7:06 pm.
