After reading a few threads ive heard that cleaning the map sensor on a van can help with mpg?...can anyone clarify this?
Does anyone know where its located on my MWB High roof mk6 2005 reg?, how easy is it to get to and how easy are they to clean....one post said it takes like 5 mins?....
I have a oil leak which seems to be coming from the manifold, this will be resulting in bad mpg right??...need to get it sorted!
