Video tutorial

In this video, see how a YouTuber successfully resolved an error detected on the EOBD (European On Board Diagnostic) socket, the error P20E8, which corresponds to a blockage of the injector and the AdBlue tank. Using an OBD11 reader and assisted by a decoding app, he discovered the issue: the injector and tank were caked with urea.

He removed the injector and tank and simply washed them with hot water; indeed, AdBlue is water-soluble and hot water dissolves it completely. He dried everything thoroughly and refitted it in place.

He refilled (remember that air causes urea to crystallise) and added an additive (you can find the code B0BMQTM7Q3 on Amazon for £4.69, with free delivery for Prime customers).
