Hi everyone!
First of all sorry for my bad English
I'm not a car expert, so please forgive me if I write something wrong.
I have a 2018 Peugeot 5008, 1.6 hdi, 120hp, 6-speed manual.
My problem is that while driving, for example at 100km/h on cruise control (so at a constant speed), the car suddenly starts to jerk and stutter. Then it continues this between idle and 2000 rpm when accelerating. If I get above 2000 rpm, it stops, then when I shift up, the revs drop and it starts again in every gear until 2000 rpm
If I rev it in every gear and drive for about 5 kilometers, it goes away and doesn't reappear for days or even weeks, but sometimes it comes back after just 2 days.
I've driven it in cold, hot, rainy, and humid weather; it does it with both a cold and warm engine – literally whenever it feels like it.
The check engine light does not light up, there are no fault codes in the diagnostic memory either.
We tried looking at live data from the car while driving hoping we could find out more, but of course, every time we tried, it never showed the jerking, everything was fine, every parameter etc
The crankshaft sensor was replaced – that's what my mechanic and I suspected first. I was happy for about 2000 kilometers, then it started doing it again – so it didn't solve the problem unfortunately. (Although I don't understand why there was no problem for 2000 kilometers).
As a layman, I suspect the camshaft sensor, or maybe the fuel pressure regulator – I'm including the part number here in case I didn't name the part correctly: 0 928 400 779
or could it be the MAF that is at fault? I really have no idea
Does anyone have any ideas?
Please help, because I'm starting to lose my mind over this whole thing!
AI: Have there been any recent maintenance or repairs done on the car, aside from the crankshaft sensor replacement?
No, because we don't have 100% information about what's the problem
AI: What type of fuel are you using, and have you tried using fuel from a different source to see if it affects the issue?
I'm using OMV MaxxMotion Performance Diesel, and yes, I have tried using other fuel, but there was no change
