Update:
After cleaning the EGR, now the lean condition is permanent at around +9 LTFT. Doesn’t go down under throttle. 🙁 goes down to around +4 at load when driving. EGR valve gasket was replaced after cleaning and also added some high temp RTV sealent just to be sure. Please anyone, any ideas? No error codes, scanned at a garage with a proper scanner as well. Thanks…
