Hi guys, would like to refresh my engine soon so I wanted to ask if this is necessary at all or if it makes sense and if yes, what would you renew if the engine is open? 195 tkm had no problems up to now, oil consumption about 1 liter on 2000-3000km No oil loss or anything else that car runs like on the first day .. .. Ohso the TÜ engine is so with 449 ps. And would you like to make a software optimization at such a mileage or rather the fingers Leave it?
