prime

Hi all, changed to a 2019 Leon mk3 2.0 diesel FR. I don’t own an OBD eleven, considering getting it. Has anyone used it to prime the fuel after a fuel filter change? cheers.

Which would you choose? It's nearly time for the car's first detail of the year and I need a good, slightly abrasive polish to cut back a couple of light marks and swirls. I have heard equally good things about both products but the fact that I can obtain the latter in Halfords, puts me...
