EGR Blanking

[Baz1912]

I have read on several forums about EGR Blanking. What are the benefits of doing this and under what circumstances should it be done ?

Cheers.

All the evidence is inconsistent some say it works others say it causes problems with the ECU so I've come to the conclusion that a good clean now and then and leave it alone is all it takes. Its the driving technique which counts - otherwise get it remapped for what sort of performance you want.

EGR blanking is really usually done cos if the valve sticks open you'll get poor response and it will smoke like hell. It doesnt really increase performance noticeably. Blanking could give issues with failing emissions on the MOT test.
