IAT and MAP sensor issues with my audi q5 2012 3.2 prestige

[OasisFan88]

soooo, I got a secondhand 2012 q5 3.2 prestige from capital one and I have been enjoying it however I have been getting problems with cel like it's very random, it comes at very random parts of the day. I am not sure why? I just read the obd scans and the codes P0107, P0109, P0110, P0112, P0114 have been appearing, and i think they are all related to the intake air temp & manifold air pressure sensors. what do I need to do? I am planning on changing/cleaning the sensors but I can't find them? can anyone point the location to me? the sensors seem ok with performance in the charts so I am nottt sure why this keeps happening. the cel resolves on its own btw.

I dont have much experience here but it sounds like you're dealing with an intermittent sensor issue related to the MAP (Manifold Absolute Pressure) sensor and the IAT (Intake Air Temperature) sensor. The sensors often work together, and which is why multiple codes can show up at once.

ooh thanks for giving that idea about intermittent sensor issue. I see. yeah, it's the iat and map for sure. I can't find it tho... where is the location of it if you know?

It definitely sounds like the MAP and IAT sensors are causing the issues primarily since they often work simultaneously leading to multiple codes. Inspecting the wiring and connectors for any damage or loose connections could help pinpoint the problem since intermittent CELs frequently stem from these. The MAP sensor is usually on the intake manifold, while the IAT sensor is part of the air intake system. Cleaning or replacing them might be worth a shot but addressing any wiring issues 1st is the practical way to go.
