Fabia Fault Codes (Just purchased car)

Hi guys,

Just looking for a few opinions here.

Bought my wife a 2012 Mk2 Fabia (1.2 Greenline TDI CR CFWA) a couple of weeks ago from a reputable small garage.

MIL appeared after about 8-9 days. Comes on for hours then off again. Rinse and repeat. It is throwing 3 codes:

P2016 - Intake Manifold Position Sensor (Circuit low)

P2015 - Intake Manifold Position Sensor (Range performance)

P0672 - Cylinder 2 Glow Plug Circuit

I saw that you can use a bracket to limit the actuator movement on the 2/3 litre engines, although I don't think a similar fix exists for the 1.2.

1. How big an issue are these codes likely to be? Do we require an immediate fix?

2. What would you expect from the dealer that sold us the car in this situation? Is it reasonable to expect a fix?

Cheers,

Joe.

ETA - The dealer is 4 hours away, so having them get their own garage to take a look isn't really an option.

Light is now on constantly.
