So I have 3 bad messages, and an unknown engine code error. Drives only about 10 mph.

1. SRS Airbag service Urgent
2. reduced Engine performance
3. Engine system service required

I have a thing I can not identify, it is under the drivers headlight, seems to be a vacuum device. I have a number that is readable from the photo, has about five wires plugged in from the back side. pic attached

I thought I had plugged everything in, but know I don't know. I did find a secondary knock sensor, that the 2.5T doesn't use.? Pic attached

Any suggestions about the error codes 2, 3?

Thanks guys

 

First plug is not used. That's just a dummy plug to prevent corrosion in the connector.

Not sure on the second one. Are you sure the exhaust cam sensor is plugged in?

 

I finally toke it in, I asked about that second one, the guy thought it was for a headlight washer system. May not be needed on my car. Since that washer was working fine, I agreed with him. tomorrow, we will see what the codes are. After spending some time feeling hypochondria about car things.
Seems the web favors or suspects ETM, MAF, I have seen a fuel filter suggestion. Since the car has been sitting since Feb, maybe there is bad gas. H2O, or something like that.
