Peugeot 308 - Video tutorial

Model: Peugeot 308 MK 3, P5 - Years 2021-2024
Part: Checks and maintenance
Operation: Troubleshooting AdBlue P20E8 and P20A2 issues on a Peugeot.

In this video, we can see that the previous owner of this Peugeot had solved their problems with the AdBlue control unit by removing the contacts. Unfortunately, this is a solution that many desperate Peugeot owners adopt, but it is not the correct one. Let's see instead how to do it: with the error code P20E08, the only option is to replace the tank, but first we remove the control unit, which we verify through the electronics and restore to the original Peugeot factory data. Then we put it back in its place and change the AdBlue tank. Afterwards, we reset the error code using the EOBD scanner (of course, here we do it with professional equipment). AdBlue starts working after the catalyst reaches a temperature of 200°C, so if we want to see the problem, we need to heat up the catalyst properly, otherwise it won't show any issues. We completely agree that a used car being sold must be original, there should not be any strange modifications made by the users.
