P0103 error code (RAC handheld) - MAF??

[andreweaves]

Hi all,

I am getting the engine light coming on nearly everytime I start the Caddy (2K engine). The van starts straight away, no cold issues and the light comes on straight away without the throttle being pressed.
Clearing the engine code using the RAC scanner is fine until I next start the van either the next time, or time after.
The running of the van is chugging until around 1800rpm and then the turbo is quite abrupt and powering away. The chugging tends to reduce once warm, but not always, it can still happen even when it has been driven for a long time and it's hot. Motorway running is fine, plenty of power on the upper ranges.

Is the code a failing MAF sensor or more of a generic code for something else??
