Jaguar XF X260 R-Sport 2.0l Diesel - P0299

[johnharland]

Hello All,

As with the title, i have a 2017 Jaguar XF X260 R-Sport 2.0l Diesel. The issue i have is - P0299 Error code for Turbo Charger underboost

Initially also had an error with MAP sensor so have replaced that with a part from Jaguar.

DPF / EGR has been checked and is ok, have Smoke tested and found no leaks, Pressure tested also with the same result.

Got to the point the only thing it could be was Turbo, took that off and to a local company that said it looked like the turbo had an impact so replaced the turbo - This also didn't fix the issue.

I have searched as much as i possibly can to determine what else this could be and am now at the point where i need to post the specifics to hope that someone else has seen this and steer me into the right direction.

Im also booked in with Jaguar for a diagnostic but thats a long time away and am in dire need of hopefully resolving before that comes to pass.

Any help / insight is massively appreciated

Cheers

John
