Crankshaft Bolts: Problem Also for 1.6TD Engines?

Hello everyone!
Does the problem of the pulley keyway wearing out due to insufficient bolt preload also occur in the 1.6 TDI engines, or is this a problem specific to the larger 1.9 TDI engines? I have a 1.6 TDI engine in my Golf 1, and could problems with that bolt arise due to the significant increase in power to approximately 110 hp?

Hi,

"This also occurs with the AAz (1.9 TD) engine. I personally haven't encountered any cases with the 1.6 engine (what do the experts say?). In your situation, I would recommend proactively replacing the screw if you drive aggressively."
