Skoda timing belt changes

Could you help me with advice about when timing belts should be changed? I have two cars... A 2003 Skoda Octavia VRS (AUQ engine code) with 105,000 miles on the clock. The recommendation for changing the timing belt ranges from 40,000 miles (local garage) and 60,000 miles (Haynes manual) to 120,000 miles (handbook).

A 2009 Skoda Superb SE 2.0-litre TDI PD (BMP engine code), with recommendations from 40,000 miles (dealer) to 90,000 miles (handbook).

I have been unable to find the current manufacturer’s recommendations online. Ian Evans

When checking different sources, I was surprised at the variation in recommended replacement times. I assume that some of the times have been shortened as a precaution.

For the Octavia VRS fitted with a 1.8 (AUQ) engine, the Skoda recommendation is to check at 60,000 miles and then at every 20,000 miles, replacing the belt at 120,000 miles or four years, whichever is the sooner. This explains the variation in recommended change times, because, as far as I know, no one will check a cambelt and guarantee it for the next 20,000 miles. For peace of mind, I would replace it at 60,000 miles.

For the Superb with an engine code of BMP, the official recommendation is to replace every 100,000 miles or 48 months. It is also recommended to replace the tensioner pulley at 200,000 miles, although personally I would replace the tensioner at every belt change.
