Forgive me if this has been covered, i did search to no avail...
Is there a way to know if the PCM has been updated to the latest version (or which version)?
Background: '07 mk7 2.4 rwd lwb
I changed the injector seals and cam cover gasket to try to solve an oil leak and knocking noise, reset prv counter, ran pump learn and injector pilot learn. Van ran better and quieter for first 5 miles, felt loss of power/misfire at 2500rpm/55mph, powertrain light came on. Went home, read the codes.
P0089
P116E
The prv had been activated and was now showing the standard symptoms of being blown. Ran a pump learn again hut to no avail.
Is it just a case of PRV and update the PCM? Sensible to do SCV as well? Im loathed to send it to a garage as i haven't used one in 20 years but understand i probably cant do the pcm update with forscan. Im just surprised at 14 years old if the van hasnt been updated already.
Any help appreciated.
