The common place for problems on these is the timing chain.If this is allowing valve timing to drift it would cause low vacuum and hence MAP sensor codes.

No.1 piston tdc, other end of the engine is a cover over the end of each camshaft held on by a 10mm bolt. Remove covers and there is a slot in the end of each camshaft. These are for the timing tools and should be in line. It is obvious if the chain is worn. Search archives, now you know what to search for, as I'm sure someone magic-ed an illustration of this,

Hi Stuart,

Laser list it as 4083. This is for 1.2 AZQ and BME engines. Listed as a chain though. I got this from a GSF/Laser catalogue that arrived yesterday.
