i have a fabia 1.6 tdi that has gone into limp mode i have done a code read and it is giving 2 codes P0236 and P0238 both are active/static boost sensor (A) circuit range / performance and boost sensor (A) circuit high input can anyone advise me what to check or replace 

Those codes are originated by the MAP sensor, however they do NOT necessarily mean the MAP sensor is faulty, they indicate that the turbo may be over boosting, possibly due to a stuck wastegate which is a mechanical fault that the computer cannot know about. Further investigation is needed, does the car enter low torque mode?

yes the car goes into limp mode and flashing glow plug light comes on 

Hi, did you get this issue sorted?

yes it was a broken wire to the map sensor right next to the plug got a replacement plug with wire from the breakers then replaced the map sensor at the same time the car runs like a dream now
