jddaigle Forum member RichardSEL was kind enough to send me a Word file he has containing a comprehensive list of the readouts available in the Climatronic unit's Diagnostic Mode. It's a great resource that I thought would be most helpful as a post in the forums, so my slightly edited version follows: About the 2C Climatronic System in the B6 The Climatronic system consists of a self-contained controller integrated into the dashboard module. It communicates over CANBUS with the ECU and a range of sensors to maintain the requested temperature in either one or two zones. More information on the B6 Passat's HVAC system can be found in the B6 Self Study Program on pages 66 thorough 69: http://www.volkspage.net/technik/ssp/ssp/SSP_339.pdf and in the Touareg Self Study Program on pages 50 through 61: http://www.volkspage.net/technik/ssp/ssp/SSP_301.PDF Common Issues Some 2006 VWs and Audis received A/C compressors with faulty clutches that would seize up. It's likely that all of these have been replaced by now, but if you have a compressor failure in a 2006 contact your local VW dealer to see if the recall might cover you. The G65 refrigerant pressure switch can develop a leak, venting all of the system refrigerant to the atmosphere and causing the A/C to stop working. You can check refrigerant pressure using the Diagnostic Mode as described below. The correct type of refrigerant is R134a and the full charge level is 600g by weight. Climatronic Self-Test and Diagnostic Modes System Self-Test The system self-test will query all the components of the Climatronic system to make sure they are all operating within spec. System Self-Test mode can be activated by pushing the ignition key to the "run" position (the engine does not need to be running) and turning on the Climatronic unit, and then holding down the "ECON" button (this may be marked A/C, depending on the year of your car) and the Foot Vent or "Down-Arrow" button at the same time until both of the temperature displays show "iO", a common abbreviation in German for "in Ordnung" which means "OK" or "Operating Normally" (if you have a later Climatronic unit without temperature LCDs, this info will be displayed on the LCD of your stereo head unit). If an error is encountered error codes will be displayed as a hexadecimal number in the left hand temperature display. You need to convert the hex code to decimal (you can use an online converter like this one). Then you can take the decimal equivalent of the code and check it in the Ross-Tech Wiki URL. For example: hex code 0E5 = 229 in decimal = http://wiki.ross-tech.com/wiki/index.php/00229 in the Wiki, which is the VCDS page for the coolant fault pressure. A list of hexadecimal error codes and their descriptions follows: 0E5 Coolant pressure 1BD Loss of Refrigerant 119 Driving Speed Sensor 214 Supply Voltage (B+) 21A Reference Voltage 510 Temperature Sensor for Body-Directed Airflow (1296) 511 Temperature Sensor for Leg-Directed Airflow (1297) 30B Temperature Sensor for External Temperature at Fender 311 Dashboard Temperature Sensor 313 Fresh Air Intake Duct Temperature Sensor 332 Evaporator Temperature Sensor 333 Coolant Pressure Sensor 318 A/C Pressure Switch F129 31C BEMO(?) for Temperature Sensor 31D Solar Radiation Photo Sensor 382 Compressor Outlet 4F7 Air Flow Flap Positioning Motor (V71) 4F8 Central Flap Positioning Motor 4F9 Fresh Air Blower 4FA Faulty Recirculation Flap Positioning Motor 25B Positioning Motor for Foot/Defrost Flap 4B6 Service Life Signal 538 CAN-Bus 513 Gateway 53D Estate 4AE Gateway Database Version 414 Control Unit Not Programmed 43F Basic Setting Not Executed 62E Coolant Temperature Sensor Signal 94B Positioning Motor for Left Side Vent (V299) 9CC Temperature sensor for Refrigerant (G454) 000 No more codes to read 444 No errors Flapper Self-Test Mode In Flapper Self-Test Mode, the control unit cycles all of the servomotors for the air distribution flaps inside the main plenum. Flapper Self-Test mode can be activated by pushing the ignition key to the "run" position (the engine does not need to be running) and turning on the Climatronic unit, and then holding down the "ECON" button (this may be marked A/C, depending on the year of your car) and the Face Vent or "-->" button at the same time. Diagnostic Mode Diagnostic Mode allows you to query the components of the Climatronic system manually and see their readouts in real time. To enter Diagnostic Mode, push the ignition key to the "run" position (the engine does not need to be running) and turn on the Climatronic unit. Then hold down the "ECON" button (this may be marked A/C, depending on the year of your car) and the Recirculation button at the same time until both of the temperature displays change to "00" (if you have a later Climatronic unit without temperature LCDs, this info will be displayed on the LCD of your stereo head unit). You can now cycle through sets of system data. The set number is shown in the left-hand temperature display and is selected using the left-hand temperature knob. The item numbers within each set are shown in the right-hand temperature display and are selected using the right-hand temperature knob. The Diagnostic Mode data shown below indicate RichardSEL's own test results taken with a system with no errrors shown in the self-test mode after an 18 mile 30 min run, with aircon on, temp set to 65 degrees F, no dual zone set. These readings were then taken with the ignition key in the "run" position and the engine off. The car is a UK market model, so the control unit reports temperatures in degrees Celsius.

It's a great resource that I thought would be most helpful as a post in the forums, so my slightly edited version follows: About the 2C Climatronic System in the B6 The Climatronic system consists of a self-contained controller integrated into the dashboard module. It communicates over CANBUS with the ECU and a range of sensors to maintain the requested temperature in either one or two zones. More information on the B6 Passat's HVAC system can be found in the B6 Self Study Program on pages 66 thorough 69: http://www.volkspage.net/technik/ssp/ssp/SSP_339.pdf and in the Touareg Self Study Program on pages 50 through 61: http://www.volkspage.net/technik/ssp/ssp/SSP_301.PDF Common Issues Some 2006 VWs and Audis received A/C compressors with faulty clutches that would seize up. It's likely that all of these have been replaced by now, but if you have a compressor failure in a 2006 contact your local VW dealer to see if the recall might cover you. The G65 refrigerant pressure switch can develop a leak, venting all of the system refrigerant to the atmosphere and causing the A/C to stop working. You can check refrigerant pressure using the Diagnostic Mode as described below. The correct type of refrigerant is R134a and the full charge level is 600g by weight. Climatronic Self-Test and Diagnostic Modes System Self-Test The system self-test will query all the components of the Climatronic system to make sure they are all operating within spec. System Self-Test mode can be activated by pushing the ignition key to the "run" position (the engine does not need to be running) and turning on the Climatronic unit, and then holding down the "ECON" button (this may be marked A/C, depending on the year of your car) and the Foot Vent or "Down-Arrow" button at the same time until both of the temperature displays show "iO", a common abbreviation in German for "in Ordnung" which means "OK" or "Operating Normally" (if you have a later Climatronic unit without temperature LCDs, this info will be displayed on the LCD of your stereo head unit). If an error is encountered error codes will be displayed as a hexadecimal number in the left hand temperature display. You need to convert the hex code to decimal (you can use an online converter like this one). Then you can take the decimal equivalent of the code and check it in the Ross-Tech Wiki URL. For example: hex code 0E5 = 229 in decimal = http://wiki.ross-tech.com/wiki/index.php/00229 in the Wiki, which is the VCDS page for the coolant fault pressure.

Seems like it's the time of year when people realize their A/C isn't working like it used to! #5 · May 21, 2015 So can I do this on a 2010 VW CV I ordered a new compressor since everything I had tried did not work #6 · May 21, 2015 If you have Climatronic (dual-zone automatic climate control) you can access the Self-Test mode, yes. You can also read all of the same things with a VAG-COM/VCDS cable and software. Did you try replacing the G65? If you did you'll need to recharge the system since the G65 replacement procedure depressurizes the system. If you haven't had your refrigerant charge level checked, make sure you do before doing anything else. 0 Reply #7 · May 21, 2015 If you can check my other post I posted a video of what exactly is going on with my car when I got it back from the shop it wasn't blowing cold air so I assume that it was out of freon so then we went back to the shop recharge the freon and it still wasn't blowing cold so then I assumed it was the valve in the a/c compressor unit itself that went out so I change that depressurize the freon and then recharge it again after I switched and that did not work either #8 · May 23, 2015 I've been adding bits to that help file so perhaps there's something in there that'll help you more? You say it was working when it went into the shop? What works did you have done? PM me an email address for latest copy by return attach in .doc format. If you have the two window (Climatronic) display then you won't need VCDS to reset to default or see if there's any error codes Do you feel any cooling when car is in forward motion? Do both your fans come on when you switch on A/C? 0 Reply #9 · May 23, 2015 The fans kick on but no cold air. I don't have any screens that show anything concerning the air conditioner. I'll pm you my email address #10 · May 23, 2015 Also the work I had done to it was that I rebuilt the top of my engine so really nothing to do with ac #11 · May 24, 2015 Sounds like a Climatic system then -- unless one of the later Climatronic which you can see settings on a headunit. Without diagnostics codes you're really flying blind -- try getting one from one of the VCDS users listed local to you? http://www.maptive.com/ver3/VCDS_Locator What make of compressor? Best I can do for now #12 · May 24, 2015 Did the vcds and the readings show nothing literally #13 · May 25, 2015 If you're getting no fault code found in the (8) HVAC section of an Autoscan then it's probably your compressor -- either the RCV valve on it, the clutch drive flywheel, or the compressor itself. As mentioned Delphi are the worst culprits having had a bad batch in the past. More details in .doc. But I see you've already changed out the RCV (for a new one? If so which compressor do you have?) So that only leaves the other two as culprits #14 · Jul 19, 2015 Bump--been seeing a lot of posts about A/C lately, this might help. #15 · Jul 21, 2015 Tried system self test on wife's 07 and my 06 and neither worked. #16 · Jul 21, 2015 Yes it appears as though I'm going to have to bring it to Volkswagen to see what's going on because I've been dealing with this for months and although I do appreciate the help from the forum it hasn't brought me anything concrete or conclusive Sent from my VS986 using Tapatalk Insert Quotes Post Reply
