Hi, I’ve got two issues with my Superb and could use some solid advice. 1) AC not working System has refrigerant – it was missing about 60g, so nothing major. The problem is the compressor doesn’t run at all (0 A, 0 rpm). Here are the faults: VCDS: Address 08: Auto HVAC Labels: None

The car is newly bought, no history. I don’t know if the Climatronic panel was replaced before. The Columbus unit is dead, not sure if that could affect the AC (I assume no, but mentioning just in case). What stands out: “control module not coded” “first run-in not performed” compressor completely inactive Where would you start: coding, basic settings, or checking compressor power supply straight away? 2) Mild lowering (daily use) I want to lower the car slightly, around 15–20 mm, nothing extreme. Thinking about springs from Passat B6 Sportline (around -19 mm). Questions: has anyone done this swap on Superb? how’s the comfort compared to stock? is it plug & play or are there any issues? No coilovers – it’s a daily, just want it a bit lower but still comfortable. Thanks in advance for any useful input 👍
