Engine optimization Volvo V50 2.0D
-
hello,
I have a friend who bought a volvo v50 (100kw engine) which has DPF off (and probably EGR OFF), so there were changes made to the software.
But he has a problem, when the car is running at a constant speed, it seems to shake, if he presses the accelerator a little, the car runs smoothly, without problems. On the mechanical side, everything has been changed, but the problem persists. He suspects that the problem is in the software, but he doesn't know where these software modification operations were done before, to look there. He saw when I did the diagnostics via VDASH, that he can do an optimization, (and it appears in green, if I remember correctly) to the version: ORI + EGR+DPF OFF (100 kW Power, 340 Nm Torque). By the way, does ORI come from the original software?because I'm new here, how is it possible to help him install this software? What do I need?
Some advice would be very helpful!
Thank you for the answers!
VIN is: YV1MW755172319311 -
@sizan Ori means just EGR and DPF removed from the software, but no tuning. If you flash this software, you will need to install a blanking plate on the EGR https://d5t5.com/eshop/detail/41/egr-zaslepka-2-0d
In the optimization menu should also be an option to check if the car is running with original or tampered software.
The shaking you describe can also be a sign of a worn suspension, imbalanced/worn out drive shafts, worn engine mounts, worn transmission mounts, worn subframe bushings and so on...
What parts have been replaced, and what quality was used? Aftermarket /original? When was the shaking first recognized, or did it appear after something was done on the car? -
@T5-T6-Schnappi how do the tires look? Are they really round, or are there sign of sawtoothes or nonsymetric wear? When was the last allignment done on both axles?
