Potential Turbo Issue

great new, the simple and cheap fixes are always the best ones. owe I agree that ignorance of the weak screw paid off on this occasion

That filter looks to have been in there for many many thousands of miles.
running some liqui moli purge through the fuel system would be a good idea to clean out any remaining gunk

Cheers,

Well done Louis, feels really good when you get a simple diy fix.

I’d like to ask the experts a question.

What is the black stuff in the fuel? The fuel in the tub looks a bit like engine oil, see picture above.

Lesson learned and glad it worked :)................As you read in my thread about my lads car....we were convinced it was the turbo or something sinister but I suppose we all at some point think the worst case scenario just like we did. Chuck some redex or similar in the tank on your next fill up, wont do no harm and if you shop around you can get it for two quid a bottle.

Thanks mate, is this the stuff?

I'm going there tomorrow so could grab a pot.
 
Ah I didn't see there was a page 2 with more comments! It did feel really good when the simple fix paid off, my neighbour said I looked like a kid at Christmas lol!

I will get onto getting some "liqui moli purge" asap, can anyone confirm if the stuff in the link above is there right stuff?
 
Water in the bottom of diesel tanks is a common problem, that is why the bottom of tanks rust through and also why the bacteria in there grows to form that sludgy,slimy muck sometimes.
 
and the filter being the lowest point is where the water will collect, hence the need for the drain screw that frequently breaks
It should be opened every 6K miles and allow a little fuel to flow out to purge any water which is present

A bit of background here....
Before retirement I used to work for Lucas CAV (became Delphi) on diesel fuel injection systems. The ideal fuel supply system incorporated a water separator in the fuel feed line. The separator had a glass bowl, so it was easy to see when it needed draining (via a drain screw). This was common on tractors etc., but I think too expensive for car systems.
Apart from rough running, the reason to keep water out of the fuel injection system is to stop the system internals rusting up. Before the advent of common rail or VW PD systems the pump controlled the fuel quantity, timing, speed governing etc.
If water reached the pump, and the engine was not used for a time, the water would separate and sink to the bottom of the pump. Rusting could cause the timing system to jam - or in the worst case, seize the pump completely. I used to see this in returns from the service network.

It's simply good house keeping to drain a little fuel from the filter housing every 6K miles or so to keep water out of the fuel system
Personally I only want diesel in the fuel lines not a mix of diesel and water, this is the primary reason for the fuel filter screw existing
 
I’m at about 6k since the last change and I still have easy access to the filter.
Going to drain a bit and see what comes out.
