Yes best to get it on a code reader again unfortunately. It may be related to the MAF again or it could be unrelated I suppose. Let us know when you have the codes.

[trebus]

Code reader  said something like volume air flow circuit range performance  which I googled to find out it relates to the mass air flow sensor which has already been changed could it be a faulty part or is it something else I cleaned out  the egr which wasn't  too blocked 

[trebus]

Fault codes p0101 and p0299 how do I check the turbo is ok / broke please help                          

   Just took off pipes to turbo no play in shaft in or out up and down I sucked on pipe to actuator and it moves freely about 15 mm can move arm by hand as well so I guess the turbo is ok 

did notice while underneath that there was a small amount of oil leaking from inter cooler hoses and when driving can hear a hissing  could they be leaking air under boost 

[James]

P0299 could be an air leak so if you can hear hissing then checking all hoses/pipework would be a good place to start

Cheers for reply I have got some intercooler o rings today will fit them hopefully tonight if it ever stops raining

Fixed,  we'll nearly was split in hose that exits turbo found it by squirting soapy water over the hoses and giving it a rev was    obvious so wrapped it in duct tape and went for a spin was ok at first but started playing up again , got back to find duct tape blown to bits so new pipe ordered £27 cheers for the help

Good news, at least it wasn't the turbo then!
