Basically my vrs smokes quite badly, isnt remapped, got the cat in, so im going to change the maf sensor as mpg is down, and im going to clean egr, but, how easy is it to do? Couple of bolts? Or quite tricky? Does anybody have a step by step guide?

Regards

amazing what you can find...

If nothing is there, we could really do with getting this laid down and put in the Fab tech guide forum, along with all the other related EGR-queries.

There are a number of results on Youtube for "vw egr cleaning", e.g.

Also is there a way i can run runnig loga on vcds to find out if my mafs knackered?

Took me all day to do the ASV and EGR because a few screws were just an arse to get to

Oh awesome

I used Wynns EGR 3 cleaner to get rid of the gunk then auto sol and a scaring pad to get rid of the tarnish. polished up nice. I recommend you wear gloves as its messy

Well i have no ide where to start to even get the thing off lolol! Not used to the pd engines!

3 screws if its a not a BLT engine, and 2 big under the EGR holding the pipe to the manifold, its easy just hard to get to screws. Put a cloth under it just incase you drop a screw or allen key

Cheers for the help buddy!

Amazing that people do this in their home! animals

Usual problem is the bolt at the back, but the gasket is an O ring so you can twist the body to get better access after removing exhaust connection. All in all very easy, but very dirty wear old clothing.

i thought you were supposed to remove the egr to clean it

Any loosened crud would go into the engine. Not, I would have thought, a good idea.

Yup; take it off. I'd also suggest that the windscreen is not a safe place to put any pieces you take off - put everything in a box and, if possible, put things in the order that you took them off.

That will not clean the egr, the egr needs to come off and be cleaned and scrubbed ideally with a tooth brush and some sort of solution. The gunk and oil will not come off with with just spraying it.... all that will do is get rid of the light soot.

going to buy some marigolds today so i don't get covered in gunk

What's the difference removing from a BLT? As that's what mine is.

Mione is a BLT and the same as above I do believe.

I took off any pipes nearby that could, black one on left side of engine for a start.

3 bolts on the ASV, 2 underneath for the EGR pipe then another one for the EGR, a 10mm spanner is needed. Fiddly but not that hard.

is an Allen key not needed? how many other pipes/connections need to be removed?

no one has mentioned pulling off the 2 vac pipes

It was a bit of a time consuming job I found and leaning over the engine bay gave me back ache

I actually took off my entire manifold to clean that too, which added some further hassle and used a whole big can of manifold cleaner.

Then again probably won't do it again before either selling the car or running her into the ground....

The far bolt is the pain in the arse where it bolts to the EGR...as said once loosened off then you can kind of slide it carefully for more access but would probably be ideal with one of those small knuckle sockets because the hassle is the angle you have to get on it.

To be honest it seemed more or less obvious other than that. It about 3/5 on the haynes scale I would say.

I just cleaned mine in situ as the egr wasn't that bad...in fact really the manifold wasn't that bad either.

Probably because of my fashion of driving to that point which involved long motorway style driving at good speeds, instead of stop start urban.

Did seem to drive better following my clean out though, or was that just the placebo of having done work on it, I'm not sure.

How hard is the manifold to remove?

Best cleaner if you're cleaning your manifold and egr is actually paint thinners.

However... I done my EGR with a small pressure pot soda blaster. Took about 45 minutes and there's no way i'd have done it this clean with a liquid cleaner.
