Soon to be an E55 owner
The tube probably came off the bladder on the seats. Two screws under the back of the seat and rear panel pops off. Reattach hoses and use zip ties to secure them so they won't come off again.
Thanks for the tips on the air bladders. I'll look into that. I hope its that simple.
So far, I'm just loving this car. Much more fun than my previous C350. As I reported, I was impressed by the initial mileage on the trip home with the car (~25mpg). However, around town (mixed highway and back streets), my 'Since Start' MPG rarely shows more than 18-19mpg. Somehow, over that 1800 miles, the 'Since Reset' still shows over 21mpg. Hmm. How is that possible? My first trip home was less than 300 miles of highway. Since then, most of my trips are mixed use, 40 miles or less.
Well, yesterday I filled up, and did a manual calculation of mileage. I expected less than 20. To my amazement, it was about 21.5mpg!
Apparently, there is a pretty large discrepancy between the 'since reset' and the 'since start'. The since reset seems to be pretty accurate while the other shows it to be much more thirsty than actual. Anyway, I feel much better about driving my 'gas guzzler' now.
Still haven't had a chance to do a full detail on the car (hence no new photos), but I'm hoping with the long weekend ahead, I'll have a chance to break out the clay bar and the PC7424 buffer. The car looks great already. It should be drop dead amazing after a buffing and waxing.
I've found that I get about 16mpg around town and a hair over 24mpg on freeway trips.
