B47 2016 X3 Drivetrain malfunction. EGR?

jackstrath · 07-24-2021, 04:19 AM

Hello,

My pal has 2016 2.0d X3 on 28,000 miles which has started to go into limp mode.

Car gets used every day and does about 50-60 mile round trip daily.

I have cleared all error codes, he drove it for a day or two and i rechecked and this is the 2 codes i got;

244C00 - Boost pressure control, control error: boost pressure too low
28DE00 - Exhaust presure sensor upstream of the turbine plasuibility

Now i cleared the codes and took it for a drive to see if i could noice anything, and the only thing i can feel is what can be described as a light missfire at when accelirating, but it doesnt bring on the EML right away, if i left foot brake and load the engine up i can get the EML on right away and the code that pops up is 244C00, the second code must return after a bit of driving.

I looked at the airfilter incase it was clogged, cant hear any boost looks or see any black resadue indicating a leak, but just wondering if anyone has anything else to look for? carbon build up did cross my mind but at 28000 and no DPF issues i cant see it being that. Are the EGR valves known to fail on these engines?

Regards
Jack

Hi Jack there is a current recall on EGR's for X3's, mines being done today. Maybe check with BMW first before doing anything else.
