AGR CBBB

Translated on 27-10-2026, 10:30.

Hello everyone,
"Since I'm now using a CBBB engine instead of an ARL, I wanted to ask if there are any ways to disable the EGR system on the CBBB as well. With my ARL engine, I had mechanically disabled the EGR, but I suspect the CBBB engine has some software control over it. Are there any possible solutions?"

Only through software, there's no other way.

Hi there.

Can the EGR valve be turned down as described in the instructions on this page for the 'newer' engines? And for which engines does this apply?

Does the "newer" engines still allow for reducing the EGR (Exhaust Gas Recirculation) as described in the instructions on this page?

No, the corresponding channel is not available.

Almost everything that meets the maximum EURO 3 standard.

hi

mhm, that's annoying... and with the new ones, do you have to look into the tube

?

No, if the AGR valve is clogged, you won't be able to see through the tube because it will be completely covered in carbon deposits

Can I disable the AGR (automatic air recirculation) using VCDS? Is it possible to do this mechanically with a small metal plate, or will the control module (MSG) then throw an error?

Regards,
Steffen.

No and no. Everything will be meticulously monitored.
