Major warranty work at first service - pressure temperature sensors
Anyone know what the reason is for some major work involving removing the dashboard and air conditioning pipes during the first service? 2021 eTron just gone in for its first service and they needed to keep it in overnight because its such a big job. There were no problems withbthe car and this is all done under warranty so I assume its some recall or TSB but I'm intrigued to know what the issue is! Service receptionist was very vague on details but said something about pressure and temperature sensors?
Follow up note: it was "Enhancement campaign 87H9 replacing pressure and temperature sensors"

My guess would be the pressure valve failure that prevents the A/C from working. Blower/heater works, just not the A/C. This failure is fairly common in 2021 e-trons. Is your A/C working?

AC pressure switches turn off the compressor on low pressure to protect it. AC temperature switches turn on condenser cooling fans on high temperatures to keep things within normal range. They can be separate or combined switches.

It was Enhancement Campaign 87H9
Got my paperwork back and it is "Enhancement campaign 87H9 replacing pressure and temperature sensors" - on the air conditioning system apparently. Pretty major job by all accounts. Involved removing part of the dash and a/c pipework. All done under warranty - still don't know what the issue was but guess the sensors were failing prematurely
