Doubt you can buy either at the VW dealer with the VW card.
Indeed you're right. Too bad since nothing that the dealer offers parts wise can compare.
Why am I pushing these solutions?
You probably already know...
Because after 120k miles VW washes their collective hands of any high pressure fuel pump failures. That puts the ball solely on the car's owner. You might be able to get vwoa to cover some of the costs. But very few have reported any success with this happening to them.
So what if you replace the current hpfp with a new one from the dealer?
For starters the new part is covered by a 12month
or 12k mile warranty. This may or may not be covered if the owner installed the pump. Best advice is to have the dealer install it if you go this route.
Which again points to the best solution being from 2micron.
If the pump dies with the 2micron filter kit in place only the pump would need to be replaced.
With the CP3 pump you'll have one of the most reliable pumps on the market.
You could always worry less and drive more
