    Post EGR DELETE ISSUE

    Hi Guys,

    I currenty have an 55 A4 Avant 2.0 TDI Sline 140 (BLB) Re-mapped to 190bh

    - Recently the EGR pipe from the exhaust manifold decided it wanted to leave the bracket that it was welded too. (looks like a dodgy factory weld to me) and as a result the car sounded like it was a 4 stroke bike.... due to the hole!!

    Anyway, I was advised that as the car was remapped it would be better to delete the EGR.

    So, I jumped on a well known auction site and bought 2x delete fitting covers and a gaskett.

    Fitted the one to the side of the manifold (above turbo) where the EGR pipe had "fallen" out and left it at that.
    The chap who advised me said that it wouldnt harm anything and leave the system as it is. otherwise i would have to modifiy the water pipes.

    After doing so.......All is fine, I have better boost, more tourqe and NO smoke.

    The only issue is that the engine management light is on - does not go into limp or have any affect on acceleration, drive etc etc

    Also, between gears sounds like a mini dump-valve fitted (intermittant)

    PLEASE can anyone advise me if i neeeded to delete the inlet side of the EGR?? or is it ok as it is??

    Going to see a friend who has VAGCOM later in the week when he's back from working away to see what the error is.

    ANY HELP APPRECIATED ;o)

    Chris

    I dont know personally but the guy that owns MAS performance does a lot of egr removal so he might have the answer your looking for.

    As an educated guess, I'd say yes you have to blank both sides. They sold the blanks in pairs and you don't normally leave one side of the system open.

    Thanks for the replies.....

    I'm assuming that you block off the intake as well as the outlet??

    Run Vagcom yesterday and it came back with MAF issue as well as EGR.

    Now, I'm wondering if the MAF sensor reading is HIGH due to the extra air being sucked in as the EGR is now deleted???!!!??

    Do you know if you can increase the range through VAGCOM??? or does it have to be done on the map itself??

    If you don't block off both sides, I'm guessing you'll be pulling unfiltered air into your engine and lots of it, as you no longer have a closed system. Without knowing your engine, I'm guessing it's like just removing your air filter and having a direct intake, not good. That would give you the MAF fault.

    hi mate did you resolve the issue? am currently looking for a egr delete pipe but they isnt one for my engine? its a BPW engine code what is yours? am thinking of removing the cooler and blanking the inlet and exhuast ends and get the egr mapped out. but the egr will still be attached to the inlet manifold so will the car still run? cos am guessing if you map out the egr it will be closed and if its still on the car its goner restrict the flow.... does that make sense? ive been searching all day to try n remove the egr from my engine code because its gettin remapped sat aswell as egr removal. bit long winded
