Restricted Performance both Red and Yellow

[Frankiej]

After several trouble free months the red Restricted popped up and later the yellow Restricted alternating, obviously went into limp mode. got home turned ignition off and restarted 15 mins later warnings off and car started but normally revs at 750 but stuttered down to 500 and back up to 750. Increased revs to 3000 smooth but minor stutter. Any ideas please 😊

My mechanic was stumped as each time he did the diagnostics came up with different fault. He found a pipe that the clamp had come off when he removed the floor pan which he has now put two clamps. Following it that he found that the plastic valve on the EGR was faulty, Jaguar gave a six week delivery time and approx cost of 900 pounds he managed to get relatively new used one for 180 pounds so we are back on the road again just in time for our trip to Prague.
