I've been searching for hours now and I wonder who's right all the time.

So, my service book says after 120,000 km or more. if the timing belt is damaged by one of the 30,000 inspections.

You always write here at 90,000 km

What's the point?
P.S. Mine is made new by the previous owner at about 80,000 km, during an inspection, stood as a defect to change timing belts, then finished and a sheet metal sign in the engine compartment with the km stand and date of the timing belt change.
Maybe you can help me with that...
