Hi. 

Just wondering if anyone here has any idea what this fault means or what part of the climate control could be the problem? I've always taught from the start that my climate control isn't agressive (for want of a better word) enough when adjusting to a set temperature. And so I end up setting temperature at 16° for most of the summer. The wording of this fault would appear to back this up I think. Anyone any ideas?

 

 

08 Air Conditioning

    System description: Climatronic 
    Trouble codes:
        P171900 - Function restriction by engine control module
            Intermittent
                Date: 2020-09-12 07:03:00
                Mileage: 42240 km
                Priority: 6
                Malfunction frequency counter: 15
                Unlearning counter: 119
                Dynamic environmental data: 02868D27C1F3

 

That fault is shown as intermittent, and has occurred 15 times with a low priority.

 

Does the engine ECU at address 01 show any fault codes?

No, only other fault is in unit 5f. Something about grounding of left speaker.
