According to the service manual for our 1.2tsi Fabia it's 60k
My wife has been racking the miles up on her 1.2tsi Leon. Its not a rocket ship but shes happy and it gets over 45-50mpg, so far nothings gone wrong on it so im happy.
I think the water pumps are pretty bad on these engines - My Ibiza has the CBZB engine and water pump cracked within a week of ownership
