UK-POLOS.NET - THE VW Polo Forum

Yes, I am the lucky owner of a 2013 Blue GT that has a panoramic sunroof, heated seats, sat-nav but no ac. So I thought I start this topic to carry you on with me through this journey I am willing to follow. Also any help is well respected . I would first need a VIN number of a Blue GT Polo that has at least AC from factory. Thanks in advance! Would help me for further researching parts. ETKA or PETKA doesn't quite do the trick for just anything...

Hello,

take a look at this topic, this guy did the same thing. I think there is information that is valuable for this project

viewtopic.php?t=72533

Good luck

@giannis Thanks for reply but I don't think you get it just right. The car doesn't have climatic, climatronic or anything at all. It just has the recirculation button. No compressor, no plumbing, no belt, no expansion valve, no nothing

OK my friend, sorry, you are right. I didn't understand it correctly. I can't help you with that. Good luck with this project. Is going to be big.

all is possible
add compressor
add pipes
add radiator
I think main fan must be new one - need confirm
add control panel
add wires, valves
new belt / pulley
check if ecu support A/C coding

Well, first of all. The ECU does accept coding for AC, already checked for that, Secondly,it all sounds pretty simple but just try and take a look on all the part variants on ETKA and try figuring out which is the right one for your car, it's a nightmare. That's why I try finding a VIN number for a BlueGT with AC.

did this ECU exist with A/C ?
if yes, you can easy do SW update

Yes, it did. I told you, it's compatible...

message anyone that is selling the car, and ask for a VIN

It works but i have one error on climatronic. No comunication with J519 Bcm. I think is one bit in codding Bcm but i dont now where..
