S40 (New) Engine 2.0D : - Trying to diagnose a low power issue

Sidonas · Aug 2nd, 2020, 13:10

Good day,

I have a Euro3 2004 Volvo S40 with a 2.0D engine. It's supposed to be a 100 kW unit but it quite clearly is weaker thant that. Every single diesel that I've driven that's 80+ kW has much more torque than mine. Other than it being low on power, the engine runs fine, starts up easily, doesn't stall or lose power completely, has normal fuel economy, there are no weird sounds coming out of it, the RPM sits where it should sit, etc. There are also no errors on VIDA/DICE. It doesn't have a DPF and I've blanked and plugged out the EGR.

Since everything is supposedly running fine, I was wondering whether the real time graphing of different sensors that's provided by VIDA/DICE could help me find the culprit of the low performance problem? If so, what things should I graph to be looked at? If not, any ideas what it could be?

Thank you for your time.
