Hi I recently bought a 2009 mk5 golf 1.9tdi bluemotion estate. I had the timing belt and waterpump done a couple of days ago and yesterday my check engine light came on with a flashing glowplug light. I plugged in a Delphi program that I had from work and it came up with 2 permanent dtc's. P0113 Intake air temperature circuit high input and B0238 Boost pressure sensor too high input. Is this just the MAF or is it something to do with the belt change or something else. Thanks
