Hello All

 

Finally got the plenum off, bit off a pig, lots of pipes to renew now, right, as the plenum is off ive got wires and connectors and tubes all over the shop, lol. Now when i come to put the thing back on, its probably gonna be a nightmare.=, so was thinking of removing as much as i can to clean up the engine bay, so did a search a found a good one on the aiv removal, couple of questions, is it the same to do on a twin turbo, as the sticky is on a non turbo, and do i have to do anything with the ecu??? Secondly would really like to remove the egr system, done a search on it but theres nothing really conclusive on how to go about it, so if anyone has some pics or a good guide on the proceedure that would be great. Where the plenum locates on the egr tunes could i not just cut of the 5 cms of pipe and put a blank flange and gasket in there????

 

Cheers

 

Dutchy.

AIV is same for NA and TT. It supposly can cause it to run slightly rich at idle, but its nothing to worry about. All of the Uprated ECU chips disable the AIV if decide to fit one later.

 

With the EGR you basically unbolt it all and blank up where it enters/exits the plenum, and again where it enters the Passenger side Exhaust elbow. You can cut of the existing flanges weld them up and refit them.

 

You can also do the Plenum water bypass.

Try this link hope it works mate

Cheers for that link bud, very helpful indeed, still nothing soild on the egr front, maybe the next time someone does it they could do a write up, anyway thanks again chaps. oh i have a jwt chip in the ecu so i guess the aiv is going at the week end, then the carbon canister, then the egr, never liked the green party much anyway.

:D

ok i guess thats should be enough on the aiv front, lol

LOL...and I found this for the EGR :

bugger..pics not working

If you do the EGR as already mentioned the nut is on the pipe going to the exhaust , once removed simply cut the pipe to release the nut , drop a 5 pence piece in the hole where the pipe went into the manifold and screw the nut back in , it,s a perfect size blanking plug :D :D :hyper:

50p!!! dunno if i can afford that, right then, so this is what i need to do, cut the pipes back where the plenum locates onto below the flange then weld the flanges over and refit to the bottom of the plenum, The pipes which i have cut i presume go to the manifold, where the old 50p trick is needed, then remove the egr valve and the bits at the back, then what do i need to do?????? sorry just wanna get this straight before i do it, The aiv system first, then the carbon canister then the egr, that should tidy things up abit oh almost forgot the plenum by pass

lol,5p piece mate so its worked out even cheaper to do :rofl: ;)

Happy days, really should get my eyes tested, 5p eh, i'll have to check my stash of useless foreign coins, got some vanuatu dollars somewhere, you can get an island over there for a tenner, one of those little rascals must be the same size as a 5p.
