As the title says really. I fitted the RNSE and bought a climate control unit off ebay but the vents dont open when switched on. I have had somebody look at it with Vag-com but cant recode it or put basic settings in and it was suggested I have the wrong climate unit. I have a 2004 3.2 with DSG...............What part number climate control do I need? I have seen plenty on ebay but all have different ending part numbers...ie, 45H, 45C, 45D ect...... Thanks in advance.
