Cold Weather Start - Throttle Fault
Yesterday I started my Macan after work and was greeted by a dash full of yellow warnings. PASM/AS, Drivetrain Fault, PSM Fault, Engine Controller Fault, ACC/PAS Fault. Car had sat outside for 10 hours in -8F warming to 2F during the day. Not the first time its been started near 0F, as just last weekend it started in Hayward after a -20F night.
Called and then drove straight to the dealer for them to pull codes. Turns out it was a throttle actuation fault, which since its on the same communication bus as everything else, cascaded the fault message to all the other systems. No mechanical issue with the throttle, and my opinion is its likely a calibration issue for delaying the fault code for cold start-ups rather than a mechanical one.
A Cayenne from 2014 was 5 minutes behind my car at the dealer, with the exact same faults and issue. (Same software build). Dealer cleared the codes, checked the throttle, remapped it, and sent me on my way with the ask to monitor and call if it happens again. No software or cal update available at this point.
Just a heads up to others as this cold snap extends across the country.
