For a about 4 weeks now my Skoda superb has been going into limp mode i have had 2 garages look at the car changing the map sensor ,the scan comes up p0116 and p0238

pointing to the map sensor .it was in on Friday all day and the garage can't find the problem so thinking the only thing left is the auto techs any ideas would be greatful 

So did they change the MAP sensor? The first code is for the engine coolant sensor so I would change that as well.

Thanks for the reply i will suggest it
