In this video, I will guide you through the process of fixing the P0171 and P0174 fault codes on a Mercedes CLK320 with the M112 engine. These fault codes indicate a fuel mixture imbalance, and we will address it by replacing the Mass Air Flow (MAF) sensor.

Hello my friends, had a very bad hesitation, performance issues and bad fuel economy with my M112 CLK320 and after diagnosis of a bad MAF sensor and replacement the issue is solved, I also checked this by checking my spark plug color reading as well and the engine had the symptoms of running lean. If you find this video helpful please consider subscribing, liking, sharing and don't forget to give me your feedback and comment your experience. Cheers.

Hello sir, my 2003 clk 200 kompressor m271 - 163hp has been having a similar problem for the past 7 years and after probably thousands spent now I still can't seem to find the problem with rough idle. and shutting off one cylinder. It works fine, but as soon as I put in neutral(it's a manual) it's turning off 1 of the cylinders and starts working with only 3. After turning the car off and on again, it's working fine again. I've replaced spark plugs,new coils, MAP sensor, MAF sensor, both o2 sensors- probably the most expensive one and still can't find what the issue is. Went to a couple mechanics and no one found the problem as they said it could be so many reasons for this. I started thinking it's the crankshaft and camshaft (have not replaced them), but the start of the car seems fine without hesitation. If you have any recommendations I would be very happy to hear. Thank you !

Check 1. the power to injectors... this needs a noid light from ebay cheap. 2. Compression test. Buy a $15 gauge and check if all the cylinders are consistent.

Mine only hesitates the first 3 starts . Then it acts like a fast car should.

[@BenzAddiction]

Yes, it is not always there...

​@BenzAddiction should I start changing sensors? 2001 s600 v12

[@BenzAddiction]

@armenvegas I recommend you to scan with a proper scanner rather than throwing money on this, as everything on the V12 is expensive, Sparkplugs, Wires, sensors, etc...

Hello sir, I have the exact same Problem Codes P2086-001, P2017-001. I deleted the codes and it came back after shutting down and starting the car again, I replaced the MAF sensor, all 5 Hoses and the 16 Sparkplugs without any results. The car doesn’t lack Performance but sometimes stutters when speeding, I had rough idling before but after change it’s better but not smooth as I used to before. Any ideas here ?

[@BenzAddiction]

Have you replaced your camshaft and crankshaft sensors?

[@OB63500]

@@BenzAddiction I replaced the camshaft sensor. But not the crankshaft sensor. Maybe I should do that next? Did you change both of those with your MAF too just not in the video? Thanks for your responses I hope you can help me further.

[@OB63500]

@@BenzAddiction Hello again sir, i now also replaced the crankshaft sensor, the shifting problem still is occurring but the car doesn’t shake anymore. Maybe i will need a Transmission Flush? My car has around 95.000 miles.

@@OB63500 reset your transmission first, I have a video on my channel on this.
