Hi i am new here and would really like some help please I own a 56Reg Golf Fsi 1.6 BLF engine. I recently had a flat battery and since then car will not start.I plugged in a vs450 code reader and got a error code of P0404 which is the EGR valve.
I have removed EGR from car i have tested electrics and they are working fine all cogs are fine and the valve opens and closes smoothly. I did clean all dirt from valve with carb cleaner,however with the valve closed if i blow into pipe from other side i can feel air escaping from valve, is this normal or should the valve be airtight with no air possible to pass through with valve closed. Thankyou for any clarification on this
