VW TDI Injector assembly cleaning and new nozzle install for ALH engine

Showing the order of parts for reassembling your VW ALH TDI injector

In this case the injectors got their first cleaning and new nozzle tips since the car was newly assembled at the factory in 2001 and it is now 2020 215,000 miles later.

Soak in diesel Kleen, then you can use brake cleaner if desired for “poor mans” pop testing via shooting through the nozzle.

Yes, I purchased the car way back then... Before YouTube even existed.

4 New nozzles were purchased off Amazon for $99 from “TDI Upgrades” and are 520 spec, dlc coated.
And yes that is cheap but they now have 3000 additional miles and have done just fine the car still has the factory installed stock 10mm injection pump since it is a manual transmission.
