F20 120d LCI 190ps - Boost pressure
Hi,
Does anyone know what the maximum psi should be for the above car? The mrs car does not seem to be performing as well as it used to do just wanted to start ruling out possibilities. Chris |

Maf sensor out of spec more likely. This will affect the boost pressure so if boost seems low, it doesn't mean the map sensor is faulty.
Sorry don't know what the pressure should be - at a guess, around 1.5bar + |

OK great, I'll see what it boosts to and go from there, there's no engine lights or fault codes so could be fun!

If the car is some years old and there is no record of it having been changed, I'd just bite the bullet and change it. buycarparts.co.uk have a good choice depending on how much you want to spend. |

MAP is the boost pressure sensor. Sometimes the MAP sensor benefits from being cleaned. |
