What is it about the 1.6tdi that causes an issue whenever the fuel filter needs changing?

 

I have changed the filter on multiple 1.9tdi and 2.0tdi engines with no issues at all, yet every time I change it on my 1.6tdi it will not start afterwards!

 

This time the filter bowl was only opened a small amount when I realised ECP had supplied the wrong filter, and immediately I closed it up again ... yet no matter what I try; cycle the ignition and activating the fuel transfer pump with VCDS for minutes at a time it will NOT start. 

 

 

 

Are you filling the new filter with diesel before re-connecting the feed pipes.??

Yes, allowing the new filter to fill with diesel then topping right up. 

 

A friend recommended a quick blast of easy start, however the car didn't pick up and run.

 

I've borrowed a hand pump kit, I'll be giving it a go tomorrow.

If running the pumps via VCDS does not prime it ether is not going to help.

Crazy. The car was running well until I lifted the filter cover slightly, all I did was tighten it back down. 

 

I'm going to attach the hand pump to the filters return feed, and hopefully bleed all the way through the system. 

So, before attempting to fix the issue this morning I revisited my page from last year when I had the same problem. 

 

This morning, I vented the filler cap, then locked and unlocked the car and this time the lift pump activated for much longer - and the car started on 2nd attempt !
