2002 Mercedes-Benz C320 Problems

Heating & Air Conditioning -- Verified

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

Electrical & Lights -- Verified

A dead battery can be caused by a faulty seat control module that does not properly shut down.  Spilling liquids on the front seats can cause these modules to fail.

Engine -- Verified

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Miscellaneous -- Verified

Inside grab handles, the upholstery on the center console cover, and door trim panels can delaminate. Most commonly replacement of the affected part is necessary.

Drive Train -- Verified

The electrical connector at the automatic transmission may leak fluid. Over time leaking fluid could migrate through the wiring harness and damage the transmission control module. If that happens a new harness and control module may be necessary to correct the problem.

2002 Mercedes-Benz C320 Reviews

awesome car use to have a mercedes c240, compared to the c240 the c320 has a good balance of power where as the c240 felt under powered. so far this car has been good to me no major problems so far at 98k. the only thing i wish was better on this car was the head unit which looks very dated and the exhaust which is too quite. of course now my goal is to get the c32 amg which has a great increase in hp about 130 to 150 hp more

My experience with MB has been a roller coaster. I bought the car with high mileage. I keep it serviced. Here are the problems I have had with the car. My passenger door handle broke from the inside. The passenger seat motor has a shortage. It works when it wants to work. My air conditioner on the passenger side does not blow out through the vents, it blow out on the floor. My engine light came on..I needed a new EGR or ERG value and pipe...It was clogged..never been replaced before and the person b4 me didnt maintain the car well.

My costs have been far less than they were when I drove my Astro van and the ride is much better! While some may complain about the cost of repairs, I have had my oil topped off a few times by dealerships when the oil light came on while driving long distances. MB people are very courteous! I have probably spent about 3-400 yr total average for the 5+ years I have had this car (that includes oil changes and new tires). I would rather drive an old MB than any Chevy or Ford! I have even bought older ones for my kids to drive because of their reliability (including their fender benders!!)

I bought my C320 in 2007 with 42K on it.
Good records on service history.
I do my own work which I believe everyone should with the prices these dealers charge. It really is not hard, and you will save tons of $$$. There are many great sources for help and instruction on-line
that are very useful.

My problems have been:
Shade for back window stopped working. I live in NM and it stopped working in the up position so I have not worried about it.
The clicking caused by the broken actuator arm, a very common problem, clicks 5 times when the car is started. I can live with that.
I also had the seat module go out , which drained the battery, another common problem. That one cost me $800 at the dealer.
That's when I got serious about doing this stuff for myself.
I love this car on long road trips. very comfortable and believe it or not, if the cruise control is set at 65, I have gotten upwards of 32mpg
on numerous trips between Central California, North Central Washington and Souther New Mexico.

Love this Wagon!! Lot's of power and a great ride
