[jair_1990]

I just bought a seat leon cupra model 2011 with "CDLD" engine with 55,000 kms, I want to know if this car is chain or belt? and at what mileage should it be changed, according to what I read in a manual, it is at 90,000 kms. Thank you for your answers

4/5 years 50-60k miles so about 80/90km
It has a timing belt but also has a cam chain on the other side.
