Now after having the timing belt, pulleys and water pump and spark plugs changed by a mechanic shop, my car makes a weird noise a day after standing outside in 8°C.
Its an Audi TT 8n Quattro AJQ 1999 with 162.000KM.
Also the shop couldnt fix the problem witht he climate compressor and told me to come back once they have the time and the parts to replace it.
(ISSUE SOLVED: Faulty Air conditioning compressor)
