Audi A4 B8 - 2.0TDI EGR Cleaning

High mileage diesels will require some preventive maintenance… first on the list… the Exhaust Gas Recirculation valve.
Hi, I am Bogdan and I invite you to take a look at how you can clean the EGR of the Audi A4 B8 2.0TDI.
What is a “EGR”?
The EGR is an emission reduction system, that will recirculate part of the exhaust gasses, back to the engine cylinders, with the aim of reducing NOx.
Why do we clean the EGR on the A4 B8?
this part of the engine will have a big carbon buildup
by cleaning it you prolong its usable life
reduce running costs for your car
sort out emission related DTCs
protect your DPF as the EGR is needed in the regeneration of the DPF
What chemicals did we use?
Petrol - very good solvent properties
Diesel - also good for cleaning
Brake cleaner
WD40 for lubrication
and a lot of mechanical tools/scrapers as contactless cleaning is not efficient

I don't think he knew what he was doing, the bolts have to be torqued, but brave I have to say.

Che risultati da la pulizia della valvola EGR.

[@4fth911]

Teoricamente ti si accende la spia del motore avendo la valvola egr intasata ciò comporta anche a perdita di potenza percio

[@peterevans5351]

Did you replace the gaskets or is it OK not to change?

[@Romas05]

Its always best to change but if the old gasket did not leak then there is no problem leaving it there
