Hi all!

I've got a Mitsubishi Outlander 2.2 DI-D GX4 SST AUTO, with an error code of P250B (read myself via torque pro and also local garage). From what I gather, it might have something to do with the oil level or sensor, but I'm not sure.

No warning light appears on the dash, however it is lumpy on cold start (in the middle of summer) and fuel economy is poor. It's giving me ~30mpg for easy, 60mph open road cruising, which seems too low. I couldn't say if it was down on power or not as it's been the same since I bought it a month ago.

The car does have a gearbox oil leak which is being monitored and topped up. It also seems to have one fuel injector leaking a bit.

Any input would be greatly appreciated.
