I've recently picked up a MkII Superb (170 CR TDI).
The last owner had the emissions fix performed in 2018. Right at the very end of the 2 year warranty, they had what I believe was the common EGR failure. They weren't able to get it into a dealer due to COVID and gave up a little too easily.
From what I know, they took it to a VAG specialist to get sorted. It was fixed as a 'don't ask, don't tell' kind of repair - they don't know what was actually done but the issue was resolved. I'm told it's passed one emissions test since.
I'm wanting to find what the current state of what I have is. I assume my options are..
Everything is stock and it was fixed some other means.
EGR was cleaned/repaired.
EGR was removed/blanked and NOT coded out.
EGR was removed/blanked AND coded out.
DPF could even have possibly been removed??
I read I should be concerned about DPF damage if EGR has been blanked, which is why I want to find out where I stand and make sure everything is OK - as otherwise the car is in fantastic condition.
Any ideas on what I can do to find the current state of my EGR set up and where I should take things from here? Or should I not even worry..? Thanks!
