It is fine driving around local country roads up and down hills, but hit a dual carrigeway/motorway and do 70-ish miles per hour for 10 miles or so and it goes into limp mode. NO lights on the dash, no overheating according to temp gauge. Turn off the engine and re-start and it resets itself, back to normal.
MAF sensor and MAP sensors both replaced with genuine parts. EGR valve replaced in the last 18 months. intercooler pipe replaced as split.
Shows fault codes
P0234 Turbo/supercharger overboost condition
P1103 Mass Air Flow Sensor in range but higher than expected
Any ideas more than welcome.
Cheers
Steve

That was to be the next avenue to explore, that, or the turbo actuator. Cheapest option first It'll be getting changed on Wednesday.
Cheers

Thanks again Steve
