I live in Inland Spain where it is incredibly hot. On long journeys I get an intermittent problem with my Turbo. It works fine for a start and then on long hills it cuts in at 3000 rpm and then imediately cuts out again. It repeadedly does this BUT sometimes returns to normal and pulls fine. When the cars is restarted from cold it works fine. A test at my local repair shop (non Peugeot)shows no fault on his computer.
