Hi i have an audi a3 tdi 170 on a 2007 plate. I have just changed the fuel filter on it but it seems to be leaking from the lid.
I have replaced the O ring and made sure to tighten the 5 torx screws one by one and opposite to each other thus maintaining even pressure. I have checked and cleaned both the surfaces on the canistor and the lid but it and made sure they are not deformed
but still leaks. What am i doing incorrect or am i missing something? The new filter only came with an oring.
Not a very good design in my oppinion.
My other question is can i replace the whole housing for an earlier type which had top sealing ring on it(looks like olympic rings).
