Seat Altea 2.0tdi 2007 BKD - Which fuel filter?

I've just replace mine a few weeks back. I've replaced hundreds of fuel filters in my life, but this is by far the most ridiculous. There are 3 different types of fuel filters. Mine uses part number 1K0127434A. But the easiest way to check is to look at the filter housing, get the part number of the housing and then search for filters that fit that housing.
The worst part of changing the filter on these cars is that the pump needs priming afterwards which can only be done using VCDS. I don't have that and landed up having to get someone to spray quickstart down the air pipe just to get it running! Good luck!

When i change my fuel filters i clean out the housing with some kitchen roll and have some clean diesel ready to fill it prior to replacing the filter. Good to go, no need to prime.
