Mattz341 Posted February 20, 2015 Author Report Share Posted February 20, 2015 Haha! Maybe... Ill take photos as i re-install the dash.To be honest tho its such a big job and i'm not even sure if it'll be able to control the AC Yet!Currently sitting in the car, working on wiring, reminds me of camping as the rain is so loud in here!!

mk2 Posted February 20, 2015 Report Share Posted February 20, 2015 You can test everything without gassing up yet, but you'll need to trick the sensors...Not sure if the Loop AC high pressure pipe has a pressure sensor on it (as I'm not familiar with AC on a Lupo). If it does, you'll need to tell the AC controller that there is sufficient gas in the system to activate the compressor solenoid (when you turn on the AC). The high pressure sensor may be the sort that indicates, low, ok or high. You must never send a low pressure signal to the controller or it'll lock out (to stop the compressor being damaged). The high signal tells the controller that the compressor has compressed enough gas for the moment so it can be switched off until it drops to 'ok' again. I'm assuming here that the sensor is a 3 level one....Assuming you can get the compressor solenoid to energise (which tells you that the controller is happy with all the signals), then you'll need to tell it that the system is beginning to chill. A lump of ice held against a sensor might help.The rad fans should work when the compressor is on and the condensor unit (in front of the rad) is hot (you need some hot water on the sensor).Most of this is guess work as every Vdub I've worked on has a different AC protocol... Some things take priority over others.Personally I'd draw a sensor diagram and try and figure out what takes priority. Can't help much more than that, but it usually is pretty logical.Sensors:Ambient air tempCabin air temp (may not affect AC- during demist mode)High pressure line temp and/or condensor temp (if fitted).Coolent temp (may or may not affect AC operation)Evaporator temp and/or Expansion valve temp (if fitted)Dryer switch (if there is one)high pressure switch (if there is one)air recirculator flap switch (if there is one)Ac on signal/switch or whatever activates everythingcondensate too high float switch (if it has one)outputs:rad fanscompressor solenoidrecirculation control thingycabin fan(s)Yeah like Skezza says, the most difficult bit about retrofitting AC to any car/truck/tractor/boat is the compressor + belt system. I always start there, as the rest is relatively straight forward. Quote Link to comment Share on other sites More sharing options...
Mattz341 Posted February 28, 2015 Author Report Share Posted February 28, 2015 (edited) Done. (Gonna swap how it's mounted, foolishly I mounted it in the same way the old one was mounted and it doesn't look right!!)

redgti16 Posted May 20, 2023 Report Share Posted May 20, 2023 Buenas amigos, tengo un GTI y le hice el cambio a clima pero hay varios errores como la temperatura no es la misma que la del tablero de instrumentos, podrÃas hacer un diagrama de los pines? Yo realmente lo apreciarÃa Quote Link to comment Share on other sites More sharing options...
mk2 Posted May 20, 2023 Report Share Posted May 20, 2023 Hola! Y bienvenido Check that the sensors are clean. Fluff around the sensors can give you a false measurement. Quote Link to comment Share on other sites More sharing options...
redgti16 Posted May 23, 2023 Report Share Posted May 23, 2023 good thanks for your answer. The sensors are fine, but the temperatures between the frame and the weather do not match, in fact the frame does not show the real temperature, but the weather does On 20/5/2023 at 16:13, mk2 said: ¡Hola!

redgti16 Posted May 31, 2023 Report Share Posted May 31, 2023 Good, does anyone have the pin diagram here to swap to climatronic in the lupo?@ Quote Link to comment Share on other sites More sharing options...
mk2 Posted June 1, 2023 Report Share Posted June 1, 2023 If the sensors are ok, it is possible that the system needs calibrating? I don't know enough about how it works. Can you check the live data from the sensors using VCDS? You can check if the measurements are correct... pic of your spanish Lupo!? Quote Link to comment Share on other sites More sharing options...
redgti16 Posted June 1, 2023 Report Share Posted June 1, 2023 Hi, honestly I don't know how to upload photos, I'll investigate this afternoon and I'll show you. Actually, if someone had a diagram or something to wire it, it would be of great help since I haven't had a dashboard for 2 days. Quote Link to comment Share on other sites More sharing options...

mk2 Posted June 20, 2023 Report Share Posted June 20, 2023 I don't think that the wiring diagram is available on the internet. You may have to buy the workshop manual. I don't know anyone that has it. Quote Link to comment Share on other sites More sharing options...

tchouki85 Posted June 25, 2023 Report Share Posted June 25, 2023 hello having made this modification on my golf4 you can find the harness on Kufatec and for the assembly I made a tutorial on the forum golf4.fr Quote Link to comment Share on other sites More sharing options...
