DIY Diesel filter change with Bosch filter

[fletchdirect]

Hi, I'm planning on doing this to save £90 from the dealer as have the tools and a Bosch fuel filter is just £9!

The Bosch filter comes with 2 o-ring type seals. A large one and a small one. I know that the large one goes around the lid and must be done, but unsure where the small one goes. Its the size of maybe a 10p. See the image I uploaded.

Does anyone know where the small ring should go? I read somewhere where its a part for multiple cars and is not needed on some. The online videos have not used it either, just the large o-ring. The car is a 2013 Audi A3 8V 1.6tdi.

Any help would be great!!

Thanks a lot

Hi the small ring is for cars equipped with the housing that can be drained for water in between filter changes which I assume your version does not have.

Hi sorry the filter you are showing is an OIL FILTER NOT A FUEL filter.

OMG - yes, looks like amazon sent the wrong one but probably my fault!! Thanks for spotting. I'll get the right one ordered! Thanks a lot for your help.

You will need to prime the fuel system correctly , using a tool like VCDS or risk damage to the fuel system, some people claim they do this without doing this but any air in the fuel can cause issues to the fuel pump....make sure the container is completely full of diesel - the pumps are very expensive to replace.
