Hello
I recently acquired a 2020 Transit with the 2.0 diesel engine.
I know the guy I bought it from and he tells me that it has recently had the DPF deleted (but not the EGR valve). And has also had a new turbo.
I know from speaking with other in that area that the EGR is usually removed/blanked along with the DPF if that's being done. Is it bad to leave the EGR functioning if DPF is removed.. my understanding was that the EGR intake was before the DPF (manifold side), so can't see how it would make any odds.
One thing i've not noticed before is the turbo actuator keeps twitching even though the engine is off and bonnet open.
My understanding is that the turbo is new and has VGT.. is there a chance that the turbo is damaged and the twitching is the actuator trying to reset the vanes to zero position.
Or also.. more likely, is it possible that this behaviour is because the actuator / turbo wasn't trained/learned when fitted with diagnostics?
I forgot to mention that there is an engine light on for an underboost condition.
To me it seems linked.. should I try resetting the turbo actuator with FORScan?
