Hi I've got a jaguar xf 2016 20d rsport.having issues with egr.i had some code come up on the obd reader and it came back with turbo underboost overboost so I had my turbo reconditioned to try solve problem, but as fault finding don't think that was the issue,so I changed the map sensor,cleaned the high pressure egr what found was sticking abit,put it all back to gether,checked that there were no pressure leaks buy air pressure test and smoke test but no leaks cleaned top filter of the egr what's under the turbo that was gunked up so cleaned that...but I'm puzzled of the issue is still there,so as this is how my car is acting used to go on limp mode co changed turbo.but when I start the car runs normal on idle,when the car is cold it drives like a car on a manual choke car,when it's warm it runs OK but if I put gas on sometimes it wants to stall and I can hear the turbo blow off
can you help and advise plz
