xyber 1 Posted May 10, 2010 Report Share Posted May 10, 2010 coolant temp sensor maybe or check the hose between the MAF and throttle body for splits or holesUnplug the MAF and see if it improves aswell Link to post Share on other sites
squid1 0 Posted May 10, 2010 Author Report Share Posted May 10, 2010 was thinking about the coolant temp senosr, the hose didnt ave splits yday but only had a quick look ave propper look when i finish work! but the coolant temp senor did pop up once the cleared it n didnt come back! but wouldnt explain why the MAF code keeps coming up n comes up twice tho Link to post Share on other sites
xyber 1 Posted May 10, 2010 Report Share Posted May 10, 2010 Splits in the hose would cause MAF codes because the MAF would read the amount of air passing through it, but then even more would get in after the MAF and a code will be thrown up.Coolant temp sensor is only a few quid from VW so may aswell be swapped just to rule it out.

MJ Vr6 79 Posted May 10, 2010 Report Share Posted May 10, 2010 Yer I've had the air leak but it does really the same feels morelumpy but it could be tho As from what you are saying, sounds like the Temp Sensor dude..If the Air leak was still there, It'd run lumpy from initial start!
