RS4 B5 Boost problem

[mattykerby01]

Hi Guys,

Help please.......My boost keeps switching on and off which is really annoying when trying to overtake.....
I have the following fault code

17865 - Exhaust Gas Temp Sensor 2 (G236): Open or Short to Plus P1457 3510 - - - Intermittent

Any ideas? Which manifold does this little beauty live it?
Thanks

Matt
