Regards,
on and pulsates. It goes out when the pedal is released. It does not light up constantly.
Any clues as to what this may be? I can't find anything specific about it in the owner's
manual. thank you.
It will gradually go back down, but not all the way, usually staying in the mid 90s.
If this only affected the display I wouldn't care, but it seems to be linked to the climate control as when the reading shoots up like that the AC comes on.
If the only solution is an expensive MB service visit I'll just use the climate control on manual and replace the temp display with speed, but if there is some cheap sensor I can replace myself that would be best.

This would be a real money saver for little annoyances that aren't worth expensive dealer visits.
MBUSA offers only CD-based manuals these days, and not at all while a current model is still in warranty status. You should keep checking back with their website, as well, as the traditional "moratorium" period on the current C should end soon.

Regards,
My recollection is that this is hard to miss, but our car is several floors below me as I write this, in our condo garage, so I can't immediately verify it. I thought this was mentioned in the owner's manual somewhere, but I may have imagined that.
Anyway, the external sensor is indeed subject to damage. However, it has absolutely no effect on what is happening with the climate control in the car - that sensor resides in the overhead console, and has no connection whatever to the external temp reading.
Hoep this is helpful
Cam rocker arms worn locate noise r/r lt and rt valve covers r/r lt and rt camshafts inspect condition ok replace lt and rt set of rocker arms and lifters.
The problem still exists. Any suggestions or other owners with this situation.
Thankyou.
The service advisor did say something about them putting silencers(?) on a purging something or other by the frame, etc. We know nothing about cars but it was probably the purge valve like you said. I don't see anything on the work order that says purge valve, he told me this on the phone.
If it is the purge valve, would it get louder after driving for some time? Like you mentioned, it is really annoying especially for a Mercedes that sounds like a diesel when accelerating. Any Suggestions?
Thanks again for your time.
It's a simple fix.
JR
Thanks again.
Hope good luck
We'll let you know. Sincerely.
front/middle/back/left/right/bass/tweeters.
About 2 months ago I noticed the left front base - door - speaker was blown and was just going to go to an audio shop to get that pair replaced when this happened.
I never turn the radio up beyond normal "speech" levels and no other problems except a SRS airbag sensor warning that I am getting fixed in a week.
Any ideas? Is this a warrenty issue? Do you think they will try to weasel out of this and say I turned up the radio too high? I have the nav system with the upgrade audo by the way.
Thanks for any advice!
When you take it in, avoid talking at ALL about volumes and blown speakers - just focus on the distortion and tell them to fix it. I am predicting that it is in the "network", not an actual speaker problem. Let us know what they find...
Really weird. I'll see if it happens again and if so will have them look at it when it is in the shop next week.
My Current problems:
1. AC Vents. The Vent control system seems to have a mind of its own at start up and fluctuates between floor and defrost about 7 times and then settles wherever it feels like that day. Usually it settles towards the defrost vents and then forces my feet to freeze. Trying to manually adjust the vent position (turn off "Auto" and using the right control knob, works for all positions but the floor vents. Rarely, I can trick it to opening the floor vents and then I keep it that way. I suspect an intermittently working vent opening actuator or something? I could just imagine the smile on the service advisor's face when he tells me how much diagnostics alone could cost so I am trying to avoid that at this point.
2. I have noticed "thumping" noises coming from the front suspension. I used to think it was the sway bar links, but I had them replaced and that did not solve the problem. It sounds like maybe the control arm ball joint linkages or something is loose? I would imagine every high mileage C has this problem?
Otherwise the car has been good. I have noticed that bulbs do get used up quite quickly, but replacing a $3 bulb every year or so is no big deal. Just don't pay MB $60 to do it!
I would appreciate any help on the AC Vent issue. It is an interesting one!
This is NOT a good thing.
Electrical gremlins seem par for the course with the C, at least the 2001 models, but otherwise this is simply an amazing car to drive.
I could not remove totally the cover under the dashboard to connect the two electrical cables that control the sensors.
1 each part number 203-540-47-33 Cable, and
3 each part number 001-546-99-41 Cable Connectors.
These are applied to the ESP Control Module.
The dealer who did the work had to order the connectors, which were delivered overnight by the parts distributor.
As far as I can tell, this applies to all '01 and '02 Cs.
Note: All audio: radio, cd, nav, and phone through speakers do not work when this happens.
The dealer has been unable to diagnose the problem - would appreciate hearing from others who have had this problem.
