Dear all, I have a 2020 Octavia Mk IV 1.5 TSI with almost 44,000 miles on the 'Clock'.  I have tried to find the definitive replacement information for the cam/ timing belt.  So far I have seen 4 or 5 years, 40,000 to 60,000 miles, 80,000 or 100,000 miles and even no replacement required for the life of the 1.5 TSI (Petrol) engine.

 

Is there a document somewhere out there which clarifies this issue please?

Yours in confusion, Alan

Funnily enough I was reading about the 1.5tsi earlier and came across this…

 

”The 1.5 TSI has the intake and exhaust camshaft (DOHC) driven by a zero-maintenance, low-friction timing belt.”

 

Taken from here - https://www.motorreviewer.com/engine.php?engine_id=117

'Zero-Maintenance', meaning no need to replace it for the life of the engine?  Or does it mean that it does not require manual tensioning or lubrication?

Had a conversation with Marshall's Newbury about this the other day in reference to one of our company cars (Mk3.5 SEL 1.6TDI)

The official line from Skoda UK is 140k miles. It used to be 5 years, but they have now gone to mileage rather than time.

The same guidance for both Petrol and Diesel. One of the Senior Tech's said that cambelts are now so good, very strong, kevlar reinforced, that most have little or no degredation when thay do change them out.

 

Much better than the days of my old Mk2 Cavaliers with a 30k interval......

in Conti belt (CT1185) have no kevlar fibres, just glass fibres. but technology is different.

The tensile members are twisted in opposing directions (anti-clockwise/clockwise), which ensures

that the belt can’t twist out of shape.

Regularly check the outer belt that drives the alternator and air conditioning compressor, because it is longitudinally braided and when damaged, fibrous pieces are created that often end up under the timing belt and cause it to skip and get damaged.

checking timing belt every 50000 kms means pull water pump out, put measuring device and check timing, correct it if i is out of range (1.0 or 1.5 degree)

not removing plasic cover, looking to belt and evaluate its condition by lookin at it.
