My 2017 VW Tiguan with automatic transmission 157k miles just came back from the repair shop with replaced water pump, transmission service, tune up at a hefty price. They used an aftermarket all-aluminum water pump I ordered from ECS tuning, but they didn't use the manufacturer recommended g13 coolant when they refilled everything, just the normal coolant they keep in the shop. Should I be worried?
I'm considering adding an aftermarket rear seal to "bulletproof" the engine. This model came with an aisin transmission and i've serviced it religiously. Do you think there are any other major problems besides the water pump and rear seal i should look out for with the tsi 2.0?

That depends on:
- what their "normal coolant" is
- what was in the vehicle before
- if they flushed the system

if it's not broken, don't fix it.

Like all direct injection engines, valve buildup is an issue.
It's good that you're staying on top of maintenance, but you just can't account for poor VW build quality. You might consider selling before it becomes a big money pit.
thank you!!
