V70 limp mode

Erdfeld · Feb 14th, 2020, 22:16

Hello!

I am having a problem with my engine going in to limp mode. It happens only when i accelerate really fast. After whitching ignition off and then on again it works again perfectly until i accelerate again too fast. I have a 2002 V70 D5.

With a regular OBD2 i managed to get these codes "P0244" and "P0094"
When checked with vida i got these results.

I have checked vacuum leaks but there are none that i found. I checked them from the boost solenoid to the TCV. Also the engine makes a popping noise as most of you might already know about.
Also i have tried this https://www.youtube.com/watch?v=_AwrCDcekHk with no success. Still get the popping sound and limp mode when accelerating.

You need to read through the "sticky" at the top of the forum related to ECM6805 (P0244) as it could be any number of things. Put simply, ECM6805 points to an imbalance between air & fuel. It could be turbo related, air / vacuum leak, fuel supply, exhaust related or similar. With the P0094 code as well, I'd ask, when was the last time the fuel filter was changed and at MY2002, what is the in-tank pump performance like? Two quite common issues.
The VIDA screen shot doesn't show either of the generic P (powertrain) faults so would imply it's a probable transient issue.
