V50 General : Not accelerating more than 120kmh & Low traction on hills

[Kleidi]

Hello. Hope that everyone is well and safe.
Somehow (long story) I got a V50 D5 2006. I own it for 3 weeks and the first 10 days i had no chance to get out of city. Later on i drove out of city and i saw that it wont go over 120kmh and even to 120kmh it struggled too much. While in hills (normal ones - 5-6%), it struggled too much and wont go over 80-90kmh.
I was at a particular volvo service to check it out and everyone there was so surprised to hear that because the car starts perfectly. On VIDA nothing shows up. No errors!
We checked injectors and to be sure we changed the third one because it seemed a little bit noisy. Also, previously was changed the swirl flap and its electromotor. Checked the DPF and it is perfectly clean. Also, only some days ago we changed oil and all filters - all Volvo originals.
We are struggling to find the reason why this happening and can't find any, so my last hope is this forum. Hope that someone would know something and would point me somewhere :-)
Thank you in advance

Clutch?? Slipping??

Thank you for your reply.
No slipping. Clutch seems good. Gears change perfectly

Revs climbing but not reflected in speed could signal clutch slip - especially when going up hill.

Gear change would be smooth

Sounds like you have no boost or egr problem or blocked fuel filter. A problem like this is poor combustion for some reason, or lack of fuel/air.

V70: Engine Slow to accelerate / lack of power

I had a very similar problem and found replacing the temperature sensor in the exhaust solved it. If you search the forum in the above thread you may find it could apply to your problem. The thread is from 2015. Good Luck.

I dont have a D5 but previously had 2 diesels which had this exact problem. Both struggled to get to 60 - 70 mph but getting there was difficult as if something was holding the car back. Both cars started up fine and ran normally appart from this issue.

It ended up being the MAF on both cars. One car to check it was this issue, I replaced it with a cheap 2nd hand MAF which fixed the problem but obviously died soon after where I then replaced with the required OEM part.

Thank you, yes I did. We had a good chase / stint but I left a mate quite a bit behind in his BMW 328i so had to slow down. both waved and the Audi guy continued gunning it.
