DANIELP1991 Posted August 14, 2010 Report Share Posted August 14, 2010 as title,was wondering if anyone has blanked their egr off?does it make any difference att all to performance, economy etc?? Quote Link to comment Share on other sites More sharing options...
ash24 Posted August 14, 2010 Report Share Posted August 14, 2010 combustion is slower with EGR because the combustion temperatures are lower, but the spark timing is advanced to make up for this, so there might be a performance decrease if that isn't compensated for, slightly less efficient as well if nothing else is changedand obviously an increase in emissions but doubtful it would lead to an MOT failure Quote Link to comment Share on other sites More sharing options...
ash24 Posted August 14, 2010 Report Share Posted August 14, 2010 not to say that it shouldn't be done btw, some people say theres a better response but i'd be weary if nothing else is changed Quote Link to comment Share on other sites More sharing options...
99hjhm Posted August 14, 2010 Report Share Posted August 14, 2010 Blank it and try it, probably 80% blocked anyway. Quote Link to comment Share on other sites More sharing options...

DANIELP1991 Posted August 14, 2010 Author Report Share Posted August 14, 2010 might blank it off when i get time, see what it does. Quote Link to comment Share on other sites More sharing options...
jonnykell1980 Posted August 15, 2010 Report Share Posted August 15, 2010 you potentially end up with a very slight bhp and torque increase because you not putting inn a mixture of part burnt combustion gas your just using a nice fresh mixture. havent tried on a petrol, done it to a few turbo diesels, made a difference mainly seemed a bit more responsive and slightly freer reving.

CasperGTI Posted August 15, 2010 Report Share Posted August 15, 2010 Like jonny said, There could be a slight increase, but i very much doubt there will be any from you just blanking it.Like with the diesels, Id assume if you blanked it you would get an egr fault on the car, and if you remove it id think you would need to get the car remapped to actually tell what the potential is, on most modern diesels, you can get the EGR mapped out of the car so you can remove it. After all if you remove it, the car will just adjust fuelling to suit, which might send it out of trim values and bring up an engine fault light.Give it a go, see what it does.

jonnykell1980 Posted August 15, 2010 Report Share Posted August 15, 2010 you shouldnt get a fault code ive never seen one from the ones ive blanked off, as far as the ecu is concerned the egr is opening and shutting therefore working youve just stopped the flow. you would get a code removing it as there will be an open circuit. but will be very slight improvement possibly not noticeable, more noticeable on forced induction due to the greater amount of air going into the bore.

Defcon5 Posted August 15, 2010 Report Share Posted August 15, 2010 I occasionally get a EGR fault, Im sure it said something about insufficient flow, so I would imagine blocking it will throw a fault up.Let us know how you get on Quote Link to comment Share on other sites More sharing options...
DANIELP1991 Posted August 15, 2010 Author Report Share Posted August 15, 2010 yeah ill have a look and let you know.cheers Quote Link to comment Share on other sites More sharing options...
MdBrOoN Posted August 15, 2010 Report Share Posted August 15, 2010 Mines has been blanked since i got it, and vag com pics up a fault everytime i run a scan. Dunno what difference it was from standard though Quote Link to comment Share on other sites More sharing options...
jonnykell1980 Posted August 16, 2010 Report Share Posted August 16, 2010 never experienced that code but havent done it to a vag car maybe why. Quote Link to comment Share on other sites More sharing options...
DANIELP1991 Posted August 18, 2010 Author Report Share Posted August 18, 2010 whats the best way to blank it off guys?just put a plate in between#? Quote Link to comment Share on other sites More sharing options...
jonnykell1980 Posted August 19, 2010 Report Share Posted August 19, 2010 yeah just a thin plate cut the same shape as the gasket works well. Quote Link to comment Share on other sites More sharing options...

LUKEY BOI Posted September 5, 2010 Report Share Posted September 5, 2010 My mate blanked off his tdi egr valve. First time he started the car the fault light came on said it gave him better throttle response but that was about it. Quote Link to comment Share on other sites More sharing options...
nfbr Posted September 5, 2010 Report Share Posted September 5, 2010 TDI EGR Valves work in a completely different way.Blocking/Removing an EGR valve is not a performance modification at all. It's simply a way of getting rid of a fault prone part of the engine!IIRC Early sports didn't have an EGR valve. If you go on ETKA you will see that some were fitted with a Blanking plate which can be ordered from your local dealer! Quote Link to comment Share on other sites More sharing options...
nfbr Posted September 5, 2010 Report Share Posted September 5, 2010 Don't quote me on this, but:036 131 281 should be the correct EGR Blanking Plate for use on 1.4 16v Engines.you will also require 1x 036 131 550H which is the gasket.You may also need to cut down the original bolts or get some shorter bolts to fit the blanking plate! The standard bolts are M8 x 30mm and have an Allen Key head. Quote Link to comment Share on other sites More sharing options...

nfbr Posted September 5, 2010 Report Share Posted September 5, 2010 (edited) But the chances are you'd have permanently had a fault code stating Incorrect flow.Plus, Now that I think about it, You'd need something to block the flange on the side of the Throttle body also!

DANIELP1991 Posted September 6, 2010 Author Report Share Posted September 6, 2010 that diagram will come in handy, thanks. i still havent done it yet, havent had time. Quote Link to comment Share on other sites More sharing options...
nfbr Posted September 6, 2010 Report Share Posted September 6, 2010 Number 34 bolts onto the side of the Cylinder head just in case anyone is unaware of this. Quote Link to comment Share on other sites More sharing options...
arosabinns Posted September 11, 2010 Report Share Posted September 11, 2010 may aswell give it a go, ive got so many engine code faults i might try it aswell, my engine cant get anyworse Quote Link to comment Share on other sites More sharing options...
