I had a similar problem with my x type. Changed egr but no different. Idependent Jag garage tracked it down to faulty Turbo actuator. Replaced and no more problems. Hope this helps. Cheers Rod

Hi Gary, The turbo could be the problem. When I was giving the engine some chances to give the EGRs some cleaning I had to get over 2000revs, Peter.

Hi Peter Only saying gratias tibi amicus meum All the best ---Frank

My wife has a 2011 XK. We have only put 25000 miles on it when the restricted performance triangle came on. It has happened every 300 miles or so since then. It always happens when accelerating from a stop or slow moving 5 mph position. Only once did the car go 2000 miles before failing. I shut off the engine and wait 2 minutes. Car restarts and performs as normal until the next episode. probably 8 episodes in the last 4500 miles. I took it to local Jag dealer who replaced ECM (big bill) to no avail and then replaced throttle actuator {more bucks). When it continued to fail they said all the codes checked out and basically walked away from it. I took it to a local independent garage who checked wiring and air systems. So I rook it to a jag dealer 120 miles away. I am impressed with their professionalism and diligence but it has been 2 months and still not fixed. Has anyone had similar experience with failure at low speeds?

A late peply, I had the same problem on my x type. garage changed egr valve but no better so took it to independent jag specialist who diagnosed faulty turbo actuator. That fixed it and cured the problem. This was still ok 40k later when I sold it. Cheers Rod
