Boost pressure sensor

[Mark602]

Hi does anyone know where the boost pressure sensor lives on a Leon FR TDI 150??

Its on the plastic intake pipe at the front near the oil filter, its more commonly reffered to as the MAP sensor, never seen one fail, why do you need to know?

Cheers, The car is going into limp mode no boost eml on when I plug it into vag I get 18000 altitude/boost pressure sensor implausible corolation i was thinking maybe it has failed!! Going to try and clean it and see if that helps.

Try running the car with it disconnected, if the sensor is at fault, you should see some boost.

Cheers Will try that tomorrow, If I clear the code it comes straight back on as soon as ignition is turned on before engine is started thats what made me think it's the sensor, if I turn engine off and back on boost returns but eml stays on.
