    clean it and failing that blank it. IMO they arent worth replacing. they're a stupid idea and expensive to replace. all IMO of course lol.

    No the car doesn't need it
    The car will run slightly cooler in as much as act (air charge temp)
    And in turn will give not alot but a tiny bhp gain If I'm correct and it also frees up some space under the bonnet
    And if your ok with some spanners it's fairly easy you will need two blanking plates and a bolt for the little vacuum hose then job done that's as long as it's a manual one if it has an electrical connection on it then I'm not sure if the car relies on it or not but my a4 2.5 v6 tdi is egr deleted and is fine
    Hope this helps fella:yum:

    Nope I didnt have to mate if you look at it and see if the egr valve has wires going to it you prob will have to delete it of the software too
    And yeah you will need 2 of the blanking plates and any gaskets to
    Good luck mate:sm4:

    Try looking on tdisport forum, there will be info on there about EGR blanking etc.

    I am going to do mine when the weather is a bit better. I've already bought the blanking plates and they only cost £4.50 for 2 off ebay. I can give you the guys email address if you want it?

    On the 1.9 TDi (AWX engine code) to get the EGR Valve off to clean it you also need to remove the exhaust manifold so you can access all the bolts which secure the EGR Valve to the manifold.

    My plan is to blank it off first, then when its alot warmer do the cleaning bit. To blank it off all you need to do is remove the pipe that connects between the EGR Valve & the exhaust manifold and then put a blanking plates we the pipe used to bolt to, one on the back of the EGR valve and one on the manifold.

    Don't forget this info is for the AWX engine code, so may not be correct for your's. But I think the principle is the same.

    The EGR will leak and thats normal, my A4 is on 152K and is doing the same.

    In principle, yes. But will let you know when i do it.

    If you do your's before I manage to do mine, let me know how you get on and vice versa.

    I dont think theres any need for the blanking plates. A audi mechanic blanked my girlfriends awx and all he did was put a ball bearing in the vaccum hose and clear it on the computer. I have it done for about a month now and its perfect no problems since.
