Posted April 29, 20241 yr Hi all I have a 2019 insignia 2.0l diesel, with fault code P226B. Been pressure tested and has no leaks, map sensor and egr been cleaned all good. Does anyone have any ideas what it could be? It was serviced on Thursday ran fine all day then Friday went into reduced power with engine management light on. Cleared the code and again went into limp mode when hitting 3000 revs, at a loss now as to what is causing it. Any ideas would be welcome at this point 😩

I have now got ‘ service Adblue system’ on dash but it’s not the first time and according to Vauxhall it will disappear by itself eventually! It did last time so fingers crossed it will this time.
