Common Problems with CLK500
Good day everyone. My 2006 CLK500 warranty is about to expire in a month. The car really has no problems that I see. What are the most common issues with these cars and what should I have replaced under warranty before it expires?
Any help is greatly appreciated!

The only thing I have seen that tends to go out (some people may disagree) are the alternator, power steering pump, and make sure to check your tranny for any issues.

Something common that I noticed was an issue his the electric headrests, the switch seems to fail on quite a few CLK's. A couple of TCU's as well.

CLK 320
- RMS - Rear Main Seal - seal around the flywheel end of the crank. Leaking oil out the rms means slippage
- MAF - mass airflow sensor - common problem area, yet havent had any issues with my clk
- radiator - make sure you have the Behr radiator vs. the Valeo. fluid contamination makes the tranny go boom.
- trans - make sure yours has had the fluid drained and replaced, every 40k. TSBs from the dealer indicate that you should drain/replace (not flush) trans fluid every 40k. when these cars were new, it was "lifetime" fluid. all i can say is do it. that leaky seal is cheap to replace. do that too. done on both my c sedan and clk
- power steering: seal/o-ring in the plastic resrvior fails, causing fluid level to drop. ultimate solution as I understand is to replace reservoir and seal. make sure to check the PS fluid (it is special MBZ hydraulic oil - $30/liter) as it is one of the only things NOT on a sensor in our cars
That's all I can think of...Wes?

I also forgot to mention the CPS, that goes out too. Your car will have trouble starting up and the engine will experience hesitation while driving.

J/K, everything on the road has issues now and then, my Benz's are still the most reliable cars I've ever owned, keep them maintained, they'll be good to you.

Not to high jack your thread OP.
Just reading up on other stuff on CLK and came across w209world. Very good web site with info.
I may have issue with my tranny. Here is direct quote.
"The 7-speed automatic transmissions can have problems with internal component failure that cause rough shifting going up from first to second gear and going down from third to second or second to first gear. Mercedes released updated parts; the transmission will need to be removed and disassembled."
I wouldn't say real rough down shifting but i can feel down shifting from 2nd to 1st gear. Is that normal? Would it fix with tranny oil drain and refill?

I don't have maint record. From my understanding it needs new tranny fluid.
It shifts up and drives fine but only on braking. I can feel gear down shifting applying engine brake.
I guess quote is for 07 and up 550's but i have similar issues, thought i should ask.
I couldn't find Tranny DIY thread yet. . .

I didn't see tranny oil dip stick from engine bay when i change engine oil. Are the fill and drain hole in tranny pan?
BTW thanks for your help.
