Tom, thank you so much for the video. My 2007 E350 had the exact same problem. To reset the AC fault light, my old ODB2 reader did not work. I bought a brand new ODB2 (with many recommendations for Mercedes) from a different producer, which did not work either. On the contrary, iCarSoft i980 is the one that works! I followed you instructions to reset and filled the AC with one can of a/c Pro max seal and two cans of a/c Pro r134a today (36oz total). I just hope that the sealing is going to last. After having dealer services on this car for the last twelve years, with a plenty of $300+ oil changes (Service A), I found that some modestly difficult work on my car interesting!
I had to swap out expansion valve did everything besides clear the code, so tomorrow I will be getting a acon reading to allow the compressor to come on and stop the blinking light. By far the best video I have come across. Thanks.
Hi So you can refill it without clearing the code? After refill you just have to wait for the compressor to come on? I can not clear the code myself and obviously i'm trying to avoid the trip to the garage. Thanks.
Well i didn't go that path after all, instead decided to play the garage version, so refill, clear the code, 60 quid down, thought i was over it. After a couple of weeks i was again with no a/c, lost it all, so definitely a leak. Another visit to the garage, investigated but not find the leak, obviously i had to refill so they can see any sign of leakage, but no succese so far, it seems to me that where i live they do not know or have the right means or gear to locate the leak, so this time i was 85 quid down. It's going to be an expensive summer.... Thanks for your reply.
Top man! My W203 C270 CDI is in France and the last time I was there I noticed the A/C off (yes,on that model it is an 'off' light) was lit up all the time. I had arranged for a local garage to look it up when I go there next week, but now realise they won't be able to do anything without this ODB reader to reset the fault. So, plunging in, following your footsteps. I hope it works, but either way, great video, thanks!
So I live in Florida too. My 2003 is great but may have a small leak. May be less expensive over time just to add ac gas ti my system before it stops running from low pressure. Not sure how much a can of ac refrigerant costs? And not sure if stop-leak leak-shield is good for the overall ac system over time?
Tom sometimes the hoses migrate the gas as they get older thus a real slow leak. Check all the hard connections for wet oil leaks first by eye then the flex hoses . After that the compressor seal at the pulley under the car . After that the condenser in front . If the evaporator in the dash is the problem well bye bye blackbird.
Great video, I have regased my my w211 the temp comes down to around 10c but it does seem to take longer as it gets hotter, it then does not go down to 10c anymore, according to my code reader the in cab sensor the one adjacent to the front interior light is not working ,but the one nr to the ignition is working, do you or anybody else who has made a comment think this could be the problem, any advise would be appreciated.
I have just fixed my air con that had this very same issue, thanks for posting this video, had to buy the carsoft reader but it bloody worked yesssssss.
Are you sure it wont spoil the compressor cause some guy wrote a bad comment on amazon about his compressor got blocked cost him 2000$ but he bought some other brand also in my country mastercool 53909 or 53910 is available ?
Well presented. I have questions 1. If use no obd how much is the good gas pressure for ac. 2. How is the experience for leak seal.did it work for long term or temporary solution ?
Why arent all YoTuber videos this good. Its the same problem on my sons CLS and now all I need to do is clear the fault code. I have an OBD2 tool but not mercedes specific so hopefully that works or its a wallet tickler for a new one.. Many thanks. (You dont do a video how to identify which park sensor is goosed on a CLS do you :-P )
Nice video it really help a lot of people!! Just wondering what kind ofobd tool is that?? I want to buy one . Can give me a name on what brand is that or link thanks and i appreciate it
Great video! I'm having the same issue that you had and it getting hot here in Missouri, so I'm going to try doing this today. One again thank you, regards.
Hey Tom, does this fix evap leaks or any other leaks? What’s the 2 cans product names? I live outside USA and have to order it online. Currently getting a little of cold from the right side and hot on the drivers side.
Hi, I also have a slow leak in my Mercedes cls w219 I was wondering if the product you used in this video fixed the leak for you? Is it bad for the compressor at all? Thanks
I'm not sure what might be happening on mine but for some reason I can't access the AC menu I only have five options available to choose from on like you're 40 some options I'm using the Icarsoft cr plus? Any ideas on why I don't have access to the AC menu?
I bought the cr plus so that I could do other cars but will I only be able to see that menu on yours with the 40 options? Do I need to buy the icarsoft 980 instead?? Please help
Take it to your automotive store. They can reset the code for you. Oreillys has a pretty good scanner although I'm not sure if that's available in your area.
Hi Dave, follow the link in the description above. Worth pointing out that if you are reasonably technical, you can pick up a $5 port scanner on eBay and try and use the home-grown software supplied with it to scan and reset faults. I used this iCarsoft scanner to keep things simple, but it's not cheap and it is only configured for Mercs. The general purpose OBD scanners will work with any manufacturer providing you get the software to drive it.
Seen several vids (23ish) on this subject and this is by far the best, most comprehensive and thorough vid I have seen. Thanks for such a good job.

Thanks mate! I was lost at the automatic/manual stage. I live in Florida. You just saved my ass from melting. Thank you!

Superb video, 4 years on. Thanks for posting 🙏🏼
Thanks to this video, my a/c is now fixed. I used the same type of products purchased from Halfords.
This video got me past the blinking A/C Off light on my 2003 W211. Thanks 👍

Update 22 August 2016: Still blowing cold 6 weeks later after a pretty warm summer!
I don’t have an OBDii scanner. Do I absolutely need to reset the fault code?
Thanks. Same fix worked on my SLK R171.
Great Donnely. You have taught me what I needed to know about Mercedes Quick Air Con fix. Thank you Ken.
Thank you very much, I fixed my AC Aircon on my mercedes cls. Thank you again!!
Did you have to use a scanner to reset the fault?
Did you consider a pressure test with OFN prior to locating the leak first ?
Are you sure it wont spoil the compressor cause some guy wrote a bad comment on amazon about his compressor got blocked cost him 2000$ but he bought some other brand also in my country mastercool 53909 or 53910 is available ?
Most leaks come from the SCHrader valves. Evacuate then replace them.
YES, 100% RIGHT!!
There is a tool to replace them without ecacuation
I am having this same problem now ,did the leak sheild work?
Well presented. I have questions
1. If use no obd how much is the good gas pressure for ac.
2. How is the experience for leak seal.did it work for long term or temporary solution ?
The STP regas already has a leak stop component in it
😎
i did all this but still getting ac button flashing back at me :(
Did you find out what is it please
I have same issues now
Fantastic! - I have the exact same problem in my 2008 e-class --> now i know what to do :-)

thanks, nice video. detailed and concise.
do you why the slk 230 air conditioning runs nonstop?
I’ve heard these sealants don’t work or last very long . Tom how long has it lasted ,is it still cold or due for a top up ?
Great video! I'm having the same issue that you had and it getting hot here in Missouri, so I'm going to try doing this today. One again thank you, regards.
when i was searching for this product to fill my ac, someone mentioned the need of create vacuum before refill. how you do it?
Thanks mate! Cheers up
Dankeschön meine freund
Thanks for the fix it worked!
Hey Tom, does this fix evap leaks or any other leaks? What’s the 2 cans product names? I live outside USA and have to order it online. Currently getting a little of cold from the right side and hot on the drivers side.
Ok. Just saw the link and the products. So this will fix any leaks through all the lines, whereas it’s the evap, condensator, or any other a/c part?
It depends on the size of the breach. Also see comments below from someone who has similar symptoms to you.
Very useful, thank you.
Can you tell me the model of your diagnostic tool or what I must search for? I have also w212 face-lift
Check description
Do you find the leak then?
What happen if the leak is in the compressor ?
How long did this fix last? Or is it still working?
Still working.
hi friend can you give your scanner model so i can byuy one
Check description below video. All details in the link.
Hi, I also have a slow leak in my Mercedes cls w219 I was wondering if the product you used in this video fixed the leak for you? Is it bad for the compressor at all?
Thanks
It's now 2 years since I used it to fix the leak and it's still working.
That s good news! Thanks
I'm not sure what might be happening on mine but for some reason I can't access the AC menu I only have five options available to choose from on like you're 40 some options I'm using the Icarsoft cr plus? Any ideas on why I don't have access to the AC menu?
I bought the cr plus so that I could do other cars but will I only be able to see that menu on yours with the 40 options? Do I need to buy the icarsoft 980 instead?? Please help
