How to fix a VW engine light error code - P20E8. AdBlue (Reductant) Pressure Too Low

Описание

The trouble code P20E8 can usually be explicated as Reductant Pressure Too Low. (Adblue pressure)
If the engine control module would detect a variation in the reductant (Adblue) pressure as the system primes for injection delivered performance that is outside the parameters set by the automobile manufacturer, then it would store the P20E8 fault code. This would give rise to the flashing up of the check engine light.

Simply removing and cleaning the adblue injector should fix this issue.
