Hi all,

If anyone can help, I would really appreciate it. I bought my Golf MK5 6 months ago and have been suffering with performance problems ever since. More noticeably on the motorway especially going up hills. Occasionally the glow plug light flashes which brings on the engine light. I have had the fault codes read and reset but return upon the glow plug lightiing up. The codes are: P0299- Turbo/supercharger boost pressure.
P0401- EGR (exhaust gas recirculation.

I have been researching on this and possible causes from a vacuum leak, blockage, possible faulty EGR valve and relation to the turbo the turbo housing resonator leaks as it is glued together and also the solenoid actuator fails.

Has anyone had the same problem on this model and any help/ ideas would be much appreciated.
