My wifes Mk7 Golf 90TSI with DSG is booked in for a service later this week at the closest VW dealer.
The car is a Dec 2014 build, first registered in Feb 2015. So 7.5 years old, about 76,000km on the clock.

The dealer is recommending the timing chain or belt be changed, about $1000. I'm not sure if this engine has a timing chain or a timing belt. With a lot of cars where labour is involved I'm wondering if the water pump should be changed at the same time. Not sure what type of water pump this engine will have. And if worth changing while in there, any feel for how much extra this is likely to be?

Thanks
John
