EGR should we all be more concerned

...and even the same 125kW engines will have different amount of blow by among them, the amount of blow by depends form to many things (piston to cylinder seal, type of oil used, type of fuel used ……) also one of them is how the engine was run in?
It also depends how well the manufacturer designed hardware that seperates engine oil from the blow by gases.

[Greg Roles]

unlikely... the 125kw engine will run more boost than the 103kw one, so will have more blowby, and require better oil separation to have the same emissions..

Yeah I'd have to agree with that A-man.

is this a good time to bring up diesel/lpg? anyone think that would have an effect?

IMO it could make it worst.
LPG replaces diesel in the combustion, I'd be worried about the DPF (if fitted).

[Greg Roles]

LPG is a secondary fuel, and it definately raises EG temps. I figure it would only make EGR worse, as with a greater explosive force thanks to LPG, you get more blowby ( the rings) and hence more oil vapor.

LPG into a highly tuned diesel would need to be done very carefully to keep EGT's low enough, and in the 125 they are already quite high stock!

This was my EGR valve after 66,000 km. Cost to replace $270 + labor 2h

Is the engine chipped or reflashed for more power than stock?

I am beginning to regret modifying my MAF now... I hope that the removal of the mesh is not going to lead to over fuelling/excess soot/clogging

Mental note - Must buy a Provent soon...

[Greg Roles]

Mate, all the mesh does is smooth the airflow over the MAF hot wire element after the 90 degree stock airbox outlet. IF anything, removal of the grid would allow a little extra air, and the car would, at worst, produce less soot! I'm not concerned and figure it won't affect EGR / sludge at all. Can't see how it would actually.

I think it was a panic moment to be honest. I love the TDI, so just don't want to be seen harming her..
