Hello, my 1Z is a bit of a concern for me: First, it jumps very badly at the current temperatures (about 10° in the garage), but battery is fine and second, I noticed today that it is at least at the start and shortly afterwards extremely rusting. Had a proper soot stain left under the exhaust after. I guess something is not well set up? If this is a possible cause: Can you find out with VAG-COM? I recently have a (l) eider English) license for VAG-COM 311.2 dusted and would only need a cheap cable… If the whole is detectable by VAG-COM (and vul?), I would be grateful for a detailed instruction with which I find the also in the English version. mfg kaindl
