If your car has a turbocharger, there are a few signs that it might be going bad. Here are four common symptoms of a failing turbo:
1. Loss of power when accelerating. If you notice that your car doesn't have the same get-up-and-go as it used to, it could be because the turbocharger is losing its ability to boost the engine. This can happen gradually or suddenly, depending on how severe the problem is.
2. Excessive smoke from the exhaust. If you see more smoke than usual coming out of your car's tailpipe, it could mean that oil is leaking into the turbocharger and burning up when it gets hot. This usually happens when the seals around the turbocharger are worn out or damaged.
3. strange noises coming from the engine compartment . A faulty turbo can make all sorts of strange noises, from whistling and humming to whining and grinding sounds. If you hear anything unusual coming from under the hood, it's worth getting your car checked out by a mechanic.
4 . Check Engine Light comes on . The Check Engine Light (CEL) can come on for lots of reasons, but if other symptoms on this list are present, then it's likely that the CEL is being triggered by a problem with the turbocharger
