Default replace fuel filter

Where is the fuel filter on a 2008 b8 A4. Is it in the fuel tank and can you replace them yourself. Also what interval should they be changed, as well as spark plugs

Just because it was manufactured in '08 doesn't make it an '08. Yours is at least an '09 if it's an A4 B8. Attention to detail would save us all a lot of time in attempting to help you.

Got nothing for you regarding location of fuel filter, sorry.

Default A4 B8 Fuel Filter position

Hi, I have a 2008 A4 B8 2.0 TDI 170 BHP sline. Its definitely a B8 registered December 2008.
They were out in Europe from July 2008

Anyway, I also sure would appriciate finding out exactly where the fuel filter sits in mine. Its not in the engine comp. and not on the underside beside the tank. I've removed a couple of panels.

Hope someone can say exactly where it is. Many thanks

The B8 was sold as a 2008 MY car in the UK and Ireland. Tommy's car is a diesel, which is not sold in the USA. For most of the world gas cars have the fuel filter in the tank, and just because of the safety problems with unsealing and resealing a fuel tank, you should let the workshop change the filter. (The service sheet does not mention when to change it for gas cars.)

Diesel cars have two fuel pumps. One is a small pump to transport fuel from the tank to the engine mounted high pressure pump. The high pressure pump is what shoves the fuel into the cylinder. The filter for the diesel is just in front of the small pump. They are in front of the fuel tank. The picture shows it on the left side of the car.

From the manual for Ireland:

If poor-quality diesel fuel is used, it may be necessary to drain
the water separator on the fuel filter more frequently than is specified
in the Service Schedule. We recommend having this done by a
specialist workshop. If water is allowed to collect in the filter, this
can cause engine performance problems.

The manual is silent as to change interval, but in America Audi diesels filter instructions say to remove water at 15/55/95K miles, and replace at 35/75/115K miles.
