No amount of brake cleaner is going to fix a failed EGR valve 👈️🔧
Once the internal electronics are gone, they're gone.
Carbon build-up on an EGR is normal, that's the job it's doing. When the electronics inside the valve have failed, no spray, additive or trick is bringing them back. It needs replacing, and it's worth fitting a HELLA quality part when you do.
If the variant's too new for your tooling, macsRemote covers it. Connect online, raise a ticket, and the EGR gets coded or taught in using the genuine factory tool, in your workshop!
