Hi all, I have recently fitted the allard kit to my 2004 A3 2.0 TDi and am looking for a little help. First of all do you have to block the little vac pipe from the egr valve and secondly need help finding someone to help turn off the check light with vagcom. Recently had engine replaced as it dropped a valve and wrecked itself and since i got it back been losing power as if turbo cuts off. When you turn it off and on again the problem is cleared again. Advised to change the boost pressure sensor and have done to no avail. Any ideas???
