For all of you naysayers to this car, this may affirm your beliefs. My first unscheduled repair for the E500 is tomorrow regarding the heater, or lack there of. I was drenched enough from the rain to feel cold, hopped in the wagon, turned the heat on for the first time ever, and felt nothing but cold air. I doubt its operator error, since its doing it on both automatic and manual settings. My guess is either CCU or heater valve issues.
I had been thinking the last few weeks whether I should keep the car or not. Riding the depreciation was the scariest thought I had, and I really miss having a W124. There are a few 400E/E420s that are really tempting in my area. At least this is the first problem in 8000 miles and 5 months of driving.
My appointment at the stealership is tomorrow.
If its anything too involved, I will find someone with a more reasonable labor rate to perform the repair. If they say its a faulty CCU, I'll just have Bob track down a used one to pop in.
May the typical OD pompous lecturing begin, or you can wish me luck if you'd like.
