just thought id chuck this question at you lot,
can someone pls explain the idea of semi blanking a egr valve on a cdti,the reason i ask is we all no when our valves need a clean up ,ie power drops away ,gota put foot down a little harder to get same grunt.
once valves cleaned and the full bore size of the valve is as intended power is restored,heres my question isnt restricting the airflow with the gasket the same as having a clogged valve,i fitted the restricting gasket to my car over 2 weeks ago and to be honest im less than impressed,comments welcome
