I drive a 2016 Range Rover Evoque SE. It’s at 158,000km and the engine is a 2.0-liter turbo I-4.

Took it in for maintenance and they said my turbo charger is cracked. Google says that this can cause my engine to lose some power. I don’t think I’ve lost power and the check engine light hasn’t come on, so I’m not too terribly concerned. I barely drive so a little less power wouldn’t be the end of the world.

However, the dealership notes say that due to the crack, exhaust fumes are leaking into the interior of the car. I know nothing about engines—is this possible?

My question is, is this a need-to-fix-ASAP type of repair, like I will need to replace my entire engine or get carbon monoxide poisoning if I don’t address it now? Or can I ride it out for another 1,000 km or so?

Thank you!
