Members, Good day.

Only the diesel filter left to change (attended to auto box, oil & filter + pollen filter).

 

How much truth is there in having to fudge around with fancy gizmos after a diesel filter change or can I get away with ensuring that the container is full before reconnecting hoses?

 

Best, Shaun.

I just filled mine up with clean diesel, no issues. I'm sure there's a correct procedure with this, but my experience was okay.

Looking forward to a response such as this. Thanks Soakd.

I just changed my filter never bothered filling up the filter bowl though it was still half full with diesel and the car started fine. These cars have a low pressure fuel pump so it's not usual to have problems after a fuel filter change. Something like my sons Ford Focus was a total PITA after changing the fuel filter as it doesn't have a low pressure fuel pump to get the fuel up to the engine.

Thanks. All good news. Read a few scary posts so thought I'd ask. On my trusty 39 year old Merc there's a hand pump to prime

 Yes that would have been an old mechanical high pressure fuel pump / governor. I've never had an issue with changing fuel filters on modern common rail VW, Seat or Skoda engines. I know Mondeo and Focus DCi's are a PITA to bleed!

Just be careful when prising the lid off the fuel filter housing after removing the bolts. It is very easy to bend the lid causing it to leak when reassembled.

Noted. Thank you.

Give the screws a good spray the night before. The threads are exposed on the underside, so they can get gunked up, especially if it's not been off for a while. If you've got a small impact driver (the kind of scale you'd use for putting screws in wood, not wheels on wagons), it's worth using that to crack the screws off. 

 

Personally, I drain the filter housing off into a jar, so I can have a look at the state of the fuel in there, then refill the housing with a suitable injector cleaner. Start the engine up and go for a blast. I appreciate that's not to everyone's taste, but works for me.

When I’ve changed mine in the past, I’ve just knocked the ignition on and off a few times to prime.

always started with no issues
