Hi all.

I have searched the forums and have had no luck.

My wife is working my next two days off, so I have two choices:

1/ DIY or cleaning

2/ pretend there is essential maintenance needed on the car.

Given my mileage 113000 now and climbing 150 per day, longevity is the key. There is a great thread about the elephant mod I will use, but given my Egr paranoia and that it is still the original, I wanted to take off and clean.

I have a pd170. Are there any links with pictures out there as to how? I am good with my hands, but I do not even know what an Egr looks like. Even if some kind person with a pd170 would mind just posting a pic of what it is and where in the engine bay it sits, as I understand it just bolts on, I would be very grateful and I can roll my sleeves up, get some carb cleaner and a toothbrush and crack on.....

Ta, 

Jamie

not done a modern(electric) one but recall some thing to do with the gears with pics on either vw MKv or seatcupranet I would search on Fred's http://forums.tdiclub.com

1) Cleaning or DIY

She will be in the best off moods when she sees you have finished the skirting in the living room and cleaned the kitchen after she comes home from a hard days work

down to a fine art now:

wipe sides with spray bleach, then get tons of febreze air freshener and spray it all around 10 mins before she gets home. thinks I've been at it all day and I am rewarded accordingly.

think this is it.....

That guide looks like its for an egr cooler, not the valve which is situated at the front of the pd170 engine, below the intake manifold

I thought it was odd that I needed to clamp off coolant pipes. can anyone confirm I can just remove it without loosing any fluid or coolant. looks like a straight bolt off/bolt on job to me with no real difficulties....

got it, looks really easy and an hour or two for a novice...

does yours have that valve thought it was electric

well I tried and failed!

there is a metal pipe on the right of the egr with two bolts. undid them pipe came loose. undid the front bolt on the egr, but there is also one at the back. the one at the back is obscured by the metal pipe and I cannot get a hex key in there. the pipe is rigid, so I cannot flex it out of the way. I cannot trace the pipe back to the other end to remove without taking what looks like half the engine out.

just one bolt In the way!

then it haled, then rained and I got pi%%&d off and put the bolts back.:(

That's exactly how far I got. Plus if you remove the electrical plug you have to reset the valve by VCDS. I sold the car instead :-)

I`m just about to embark on this myself and from what i can see the metal pipe to the right of the EGR eventually attaches to a rubber hose so should move enough to get a hex bit in the bolt behind... also been told that as long as the ignition is off then you can unplug the electric connector, just dont turn the ignition on at any point otherwise you will have to reset it.. disconnect the battery maybe?

Have you managed to do this yet? any advice before i try would be helpful

get pics if you can. that pipe is rigid and will move about 3mm on mine. I googled that pipe and it looks like halfway along there is a bracket that holds it to the engine. I reckon if I find the bracket I can loosen it off a few turns to makethe pipe a bit looser.

There is a bracket bolted to the block. Remove the airbox and air intake pipes and you can get to it. You need to remove the pipe anyway, as you need to blank off the EGR take off point at the manifold ideally, or at the EGR cooler.

I still havent got round to this yet but hoping the weather will hold on saturday long enough for me to do it, and of course I will get pics as it seems a decent guide is lacking on here...

ta! if I figure it out first I will also.

in mean time, I have some wynns egr cleaner. just figuring where to put it (so to speak).

general consensus is in air intake after maf, but it can be varied to clean different parts apparently. I was thinking about the big rubber hose that goes in the bottom of the egr, clipping off and spraying there whilst idling. anyone know if that's going to be ok. I figured it may do the manifold some good there too and was a bit worried spraying direct into the turbo....

sent via Playbook and Tapatalk

Easy-PD, what part are you trying to clean with the Wynns stuff into the Air intake? From what I can gather doing that sort of thing whilst the engine is running is a bad idea, especially from the intake side..

Im sure there is someone on here with a more mechanical mind than me, but im not convinced that is the way to go..

Be careful and double check what you are doing as you may ruin the turbo and thats big money :-)

this stuff.

when you get bored, go to 8:55 in the video

tried to find the bracket for the pipe to no avail today. dropped my socket in there somewhere too :(

just done it, not the clouds of smoke like the vid, but for 5- 10 mins idling, there was a constant light cloud of smoke from exhaust. I'm sure it has not cleaned it like a removal, but car is smoother and the turbo spools up earlier in the revs. don't get the sudden kick of power now, it is more a constant increase if that makes sense.

still would like to take off and do, but would need pics or a guide if anyone can help- I keep losing sockets and cutting my arms searching to loosen the damn silver pipe to get the last egr bolt....

Just done mine. Bit of a pig to do. (like most things it seems on this car. Rear discs and oil filter change for example) To undo the EGR metal pipe,look in through the side of it (oil filter side) and a few inches in you'll see a small bolt (11mm) this is what bolts the pipe bracket to the engine. I just did this a few turns to loosen it off (undo it completely and I wouldn't like to imagine how hard it would be to locate it again to do it up. This gives more movement on the pipe to get it more out the way to get at the bolt on the EGR valve itself. I actually undid it with a thin nose pair of plumbers pliers but I imagine a normal set would do it to or a pair of mole grips. loosen it a bit and then you can undo it by hand and hold the EGR pipe out the way at the same time. Don't think that's it though a there is a third bolt right round the back. It is a long bolt that goes through the lower and upper parts of the EGR Valve and then bolts into the inlet manifold like the shorter ones do. Again fiddly to get at I used a T30 torx allen key to start loosening it and then used a t30 bit on a socket and undid it by hand. Then the EGR valve will come away from the manifold. Surprised how clean mine was TBH after 114,000 miles. Still took a bit of cleaning. Scraping with the finger nails,old toothbrush,cloth and a can of carb cleaner. Unplugged it and removed from engine bay to clean it and had no problems with dash lights when I fired it back up after refitting.
