Golf MK6 ANNOYING CODES P0113 P0238

[Flash2]

It says intake air temperature -40 which leads me to believe that theres a wiring issue, the problem is i dont know where or how to find where it may be, can someone help me with wiring diagrams or solutions im just an amateur so any help would be appreciated!

I can't help you with a wiring diagram but I can tell you what the problem is likely to be from the data in your VCDS scan. It looks like your boost pressure sensor earth/ground is open circuit (probably a broken wire). With no earth to the sensor, the signal voltage will be 5V (ie too high). The IAT sensor is usually built into the boost pressure sensor and shares the same earth. The sensor earth might also be shared with the DPF pressure sensor too which might explain the DPF code as well.

If you have a voltmeter and a sewing needle or a pin you can use to back probe the sensor connector I can tell you how to test the circuit to confirm my suspicion....or show me up as an idiot (wouldn't be the first time )
The only problem might be getting at the sensor...see below.

Is there any way you could tell me the way to test the ground on this circuit? I know to an old post but I have the same symptoms.
