Thanks for the 411. I will be careful when I attempt this!
I have read many of your opinions concerning the EGR. While I do agree with you, I am only prusuing this to diagnose an oil consumption issue. Any thoughts??Bookworm said:EGR can clog on gas engines also. Did you know that? Does anybody care?
Well I can certainly agree with you on the snow screen thing. Checked mine at 110,000 miles...it was completely clean. I mean it's great that I checked it but I basically wasted 15 minutes of my time.Nothing personal intended. And I don't take most things very seriously.
What I have seen over the years here is that someone will get overly alarmed over something (like an EGR valve that is supposed to look dirty) and whip others into a frenzy as though the sky was falling. Then you get a whole group of otherwise sane people jumping over the cliff like lemmings. I've seen this with removing snow screens (first it was a good idea, now people think it's a bad idea), removing the MAF screen (definately a bad idea), using oiled air filters (killed lots of MAFs), removing mufflers, venting crankcase vapors to atmosphere with elephant hoses (only to have them freeze up), wrapping the downpipe with insulating tape, yada, yada...
Oh so now EGR valve cleaning IS a good idea Believer? Come on man, which is it!That's not the type of EGR valve we have on our PD motors. Cleaning the type you've just shown would be beneficial since the soot blocks the flow of intake air. That's not the case with a PD motor.
eb2143: I've had a VERY good look at my EGR valve and intake.
That looks identical to the EGR on my Passat Tdi 130 sport which i have just cleaned and thats a PD. I didn't manage to get it that clean but i got it pretty closeThere is nothing wrong with cleaning your EGR valve. I picked up 3-4 mpg by doing so. VAG-COM'd the EGR and 100,000km later, it almost looks like the day after I cleaned it.
