Alfa 159 plugs underneath the car?

[Efbe]

Hi all

Got the MOT done a few days ago. Passed without a hitch which was nice, but whilst the car was up on the ramp the MOT tested remarked that there was a plug underneath the car that was unplugged, and that it should be plugged back together.
Thought nothing of it as I was distracted talking to someone else and didn't think about it.

Since then the TCL and Hill Control warning light come on randomly.

Now i can just unplug this again and see if that fixes it, but am more interested to know what this plug is?

To be honest it looks like a plug to the lambda port in the rear cat....

Sounds like a wheel sensor. The previous owner probably pulled the plug as the TC light kept randomly coming on! Double check if the ABS is working as well. I can't remember if the 159 uses the ABS sensor to detect wheelspin as well.
