#5197 of 7297 Possible Solution for Forgetful Key
Jan 02, 2002 (5:41 pm)
My 2001 C320 is 10 months old now. I thought I fell victim to the "forgetful key" syndrome that has plagued other owners.
Both keys started to intermittently give trouble (not opening or locking doors, ignition not working). The red diode would blink when I tested for adequate battery power. I tried re-programing the keys by inserting into the ignition lock 12 consecutive times. I tested the lithium CR 2025 batteries, and they both read "good" on my battery test meter, well into the green zone. For the past week, I have been carrying three keys with me (both Smart Keys, plus the mechanical key), in case of emergency. I did not feel like being towed, given the cold weather we now have in New York.
The Home Depot had a sale on batteries on New Year's Day (1/2 price for all Duracell!). I purchased four new CR 2025 batteries. I tested them prior to installation, and well, the new batteries were even further into the green "good" zone on the meter!
I have not had a problem yet with the new batteries! Perhaps batteries falling just short of 3V, by even a few tenths of a volt, are causing some of the key problems.
I remember my previous cars used 12-volt batteries in the remote controller, so maybe Mercedes figured out a way to cause much grief for their customers by using two 3V batteries in series.
#5198 of 7297 Side mirror drift
Jan 02, 2002 (10:45 pm)
Previously on the board I believe some people wrote about side mirror drift, i.e., after some time (e.g. a week) the side mirrors would have (slowly) drifted out of their setting and would have to be set back by pressing the memory button. I'm experiencing that, and I wonder if someone ever found a solution/had it corrected by the service center?

If I am not mistaken, battery is not needed to start car. So if your ignition was not working it was a bigger problem. After two key replacements in the first 4 months I have been key problem free for 6 months. In fact, after getting the steering wheel straightened, the keys, and a new front passenger seat belt retractor, I've been trouble free and really enjoying the car. Not your Japanese car quality but then again not your Japanese car driving experience either.
Having owned both I prefer the MB and know the long term (100K miles +) mechanical integrity is superior.
#5200 of 7297 Horrible service --- again
Jan 03, 2002 (2:50 pm)
Last Friday, I made appt at Auto Stiegler in Encino to replace tail light per indicator. They had the car all day, and at 4 pm, I got a message that they didn't get to it and would need to keep the car over the weekend and I could keep the free rental. But I didn't have a rental! I picked up the car that evening. There was no apology and no explanation. I am never bringing my car there again, nor would I ever buy a car there. This is the third time in a row that they've displayed horrible service. Coincidentally, my wife's Honda also had a tail light out. I called my Honda service guy (J&C in North Hollywood), who told me to bring it in. They replaced it in 4 minutes. What a contrast.
#5201 of 7297 Actual Solution for Forgetful Key
Jan 03, 2002 (5:59 pm)
I should have clarified... the only time I had trouble with the key in the ignition was when I was inserting 12 times to reprogram the key. Occasionally, the ignition may not recognize the key (this is mentioned in the owner's manual). Otherwise, my forgetful keys' only symptom was not locking or unlocking the doors (intermittently).
This problem was resolved with fresh lithium batteries. It wouldn't be apparent, however, as the original batteries still tested good on the battery meter (almost "like new" on voltmeter) and red diode still blinked on the SmartKey.
Wish me luck over the next 9-10 months or so... at which point I will proactively change the 3V batteries again!
#5202 of 7297 Extended Warranty
Jan 03, 2002 (6:44 pm)
I purchased a C240 several months ago, but decided at that time not to purchase the extended warranty. I have decided to purchase the warranty and have been trying to find the post that provides info on purchasing the extended warranty. Can someone provide me with either the post number that contains the info or provide any info on purchasing an extended warranty at a "good price."

You will find the extended warranty information you are looking for, on this board (i.e. the Mercedes Benz C Class) in post # 4781 by paul_p. He saved $800 compared to his local dealer. You must purchase by the end of the first year from purcahse date. Name is: Lisa Lehrbaum, Courtesy Motors, Chico, CA at 1-800-655-3535 Lisa's FAX number is 530-893-1131
#5204 of 7297 Excellent Service
Jan 04, 2002 (5:54 pm)
In contrast to Auto Stiegler's failure to fix my tail light even though they kept my car an entire day and wanted to keep it over the weekend, I took it to Downtown LA MB, where it was fixed in 10 minutes. It was fixed by the service advisor himself,with no paperwork and no waiting.
#5205 of 7297 RE: Side Mirror Drift
Jan 05, 2002 (12:22 pm)
I have been having trouble with side mirror drift as well and the dealership has looked at the problem on at least six different service visits since September (the mirror is not the only problem .... power seats, electric windows, keys, trunk, ..... and so on). The dealer has yet to figure out the mirror drift and instead has damaged the interior door panel - 2" diameter bubbles - pushed through from the back side of the soft interior door panel. They also decided to remove and lose the rubber trim that runs along the top of the interior door panel along the base of the window. If you wondered - it sounds like you are driving with a window cracked with that trim missing. It took several weeks for them to even aknowledge they had removed and lost the part. Anyway, they've replaced the trim piece and the entire door panel and the mirror still drifts. I give up. I'm getting rid of this heap as soon as I can!!
#5206 of 7297 Breaking on ICE
Jan 07, 2002 (6:53 am)
Hi, yesterday when I was driving on snow, I realize that when I apply breaks it gives me funny sound and some resistance while driving on a road with a snow accumulated; I am just wondering if this is a normal behavior of the CAR, I am driving in "W" mode - any replies would be appricaited
