Mk1 Leon 110tdi SX Fuel filter

[Slicker 1]

Hi,

Leon Mk1 1.9tdi 110SX, ASV engine, Fuel filter change.

First time I have changed one of these. It seems to be a complete unit held by a side clamp and not a separate element which I am used to on other VAG stuff and will necessitate disconnecting the fuel pipes.

1. The new filter will obviously not have fuel in it afterwards. Will the system need bleeding afterwards...if so, how is this done?

2. When buying the filter would it be best to also buy some replacement pipe retaining clips?

Any other pointers or tips would be much appreciated.

Try and get the diesel out of the old filter into the new one (a bit messy) be careful with the clips and they shouldn't need replacing and you shouldn't need to bleed it, maybe prime it once or twice but should have no problems

I recommend you do no such thing. You'll pour a goodly part of the crud from the old filter straight into the new one. Fill the new filter with clean fresh diesel.

See my reply in Slicker 1's other thread (asking the same question) for the proper procedure.
