W163 Crash Test Driver
2008 ML350 (Me!), 2010 GLK350 (Wife), 2003 ML-350 (Deceased)
It happens. I ordered a new outside temp sensor recently and when starting the car it would read about 15 degrees low, then slowly creep up to accurate within 5-10 minutes. Returned, got a replacement (same brand), works perfect from start to finish.So im guessing i just had a bad alternator with the first one.
