If the turbo housing has cracked, or the internal seals have blown, oil will start to leak into your exhaust system. As this burns off, it produces a distinctive blue/grey smoke, which will probably become more apparent as the engine revs increase just following an idle situation.

If you notice that your turbocharged vehicle is accelerating more slowly than usual, or isn’t capable of reaching the speeds it once could, this may be a sign that your turbo is failing.

Often, a failing turbocharger will make a loud, distinctive noise when under boost – a bit like a dentist’s drill or police siren if compressor wheel damaged. If you start to hear this noise from your engine, it’s definitely time to have it checked out!

Some turbocharged vehicles are fitted with a boost gauge, which lets you know how much boost your turbo is producing (you can also fit one to your car if desired). If your boost gauge isn’t going up as much as it used to, then there is a good chance your turbo is in need of repair.
