Default CEL and Code P00A8 after removing JB4 - 05-15-2022, 03:26 PM

I have been running my JB4 for about a year, and absolutely love it. However, there are several recalls on my car, plus I'm having an issue with my AC, so I need to take it to my local MB dealer to have warranty work done. I removed my JB4 earlier this week and then buttoned everything back up so that i can schedule my service appointment. However, when I started the engine, I got a check engine light. According to my OBD2, the code is P00A8 $07e8. Supposedly this is an Intake Air Temperature Sensor. I don't see what this sensor has to do with the 4 connections I had to change when I removed the JB4. Does anyone know what i might have missed when I removed the JB4 that could trigger this CEL and code?

Yes, your MAF sensor was one of your connections. Make sure it is properly secured and plugged in. If it is, try driving it around for a bit and see if it goes away.
Please let us know if it doesn't go away.

Can you confirm which of the 4 sensors if the MAF? My instructions show MAP sensor 1, MAP sensor 3, Fuel Pressure sensor 1 and Fuel Pressure sensor 2. I'd like to know which one I should check.

Thank you!

Cannon is mistaken there, for the C63 there are 4x MAP sensors and 2x fuel pressure connections. As for which sensor is throwing the fault I'm not sure, just not familiar enough with the codes to know what specific MAP sensor it's for.
