    Take out the Lambda sensor on top of the DPF. I strongly recommend you do not take out the EGT sensor, they have a nasty habit of Galling and ruining both the sensor and the DPF’s thread, which can be... galling . When you reinstall the Lambda sensor you should apply a thin wipe of anti seize paste (Copper based is not ideal) and we use Buy Alu paste AL 1100 online

    We tried it on our Passat loan car and so far so good, you will need to do a proper forced regeneration after, using a diagnostic system.
