For that last 2 months (only about 10 trips or so) I've had this issue where my 2016 Euro 5 Ducato has almost no power when I start it up. I can barely pull away. I could just about rev up the engine with the clutch down, but when getting past the 2000rpm mark, the engine starts to sound erratic up and down. The strange things is that, after struggling to drive for about 3-4 minutes barely moving with the foot to the floor, power would return almost instantaneously and the whole van would surge forward. For the rest of the journey everything would continue fine, with full power available.
Last weekend I did a 200 miles trip, and on the way back, for the last 30 miles I kept on loosing more and more power, until in the end I could barely make it home. My street is on a moderate incline, and I could barely climb it in first gear with the foot to the floor. I've checked for error codes with a cheap OBD reader and there are none stored. I don't know if an expensive / more capable one would find more. There is no check engine light on the dashboard lit up.
I looked around and accumulated a list of possible suspects:
1. EGR valve stuck open, which causes the engine to lack power when cold / on start-up. However, this wouldn't explain why I lost all power on the way back home, with a warm engine.
2. Maybe some issue with the turbo actuator - but would that fit the initial symptoms, where I had no power only for the first 3-4 minutes, and then all normal power would be restored?
3. I see people reporting issues with the accelerator pedal actuator, or the safety feature BTO (brake-throttle override). But it doesn't seem to fit my case, as the engine will rev up with the clutch down. But maybe it is worth looking into.
4. I also considered issues with fuel feed - either the tank pump (does the Euro 5 engine have a tank pump?), or the fuel filter or maybe the high pressure pump. But again, I'm not sure that fits with the initial symptoms of all power being restored after 3-4 minutes of driving.
Right now the van is pretty much undriveable. The engine sounds healthy when it starts, but if I put my foot down on the accelerator, when out of gear, there is a delay of 3-4 seconds until the revs slowly start climbing, and are reluctant to get past 2000rpm. Also one thing of note is that since all of this started, when I switch off the engine, it stops with a thump - if that makes sense - which didn't use to be the case.
I would appreciate any suggestions - otherwise I guess I will have to check and dismantle all of the above parts to try and narrow things down. Many thanks.
