Wife had the half full CEL come on when she started up the car, saying reduced power. I cleared the code when I got home, took it for a drive and nothing. Then next day, she got another CEL on the highway. Took it to the dealer who diagnose a faulty thermostat sensor

The experience did give her the chance to appreciate the all4 S a bit more, since we got a non S, for a loaner with no nav, no hid, no HK and automatic. She said she really missed her car when driving the loaner

 

was this after the service bulletin replacement or the original sensor?

 

I did not have a recall on my ALL4s but the original thermostat went out this past week - replaced under warranty

 

Original sensor. I hadn't been into the dealership since we bought the car in June.
