Drivetrain malfunction/EGR recall
Hi everyone,
So around a month ago I had my X1 (2016) in for the recall egr valve replacement. When they did the work they also had to replace the inlet manifold as part of this had melted away apparently. A couple of weeks ago I was driving along at a slow pace when a Drivetrain malfunction popped up on the iDrive, however it cleared itself within 10-15 seconds. After this the engine management light has came on a few times intermittently, it’ll be on one day then the next day it’s gone again. I have a basic OEM reader and the codes showing are:- P00BD - Mass or volume air flow A circuit range/performance - air flow too high P0471 - Exhaust pressure sensor A circuit Range/performance Does anyone have any ideas about if any of this could be related and it’s worth me going back to the dealer about the work? Or just coincidental and I’ll take it to an independent to get diagnosed. Any advice appreciated, thanks everyone Edit: Just to add, forgot to mention the car sometimes has been feeling a little rougher than normal. Seems hesitant at times when putting my foot down or even when just setting off from a stop. Last edited by DJM90; 04-10-2024 at 01:46 PM.. Reason: Forgot to add some info. |

So, have since purchased Bimmerlink and done a check of the fault codes, and I’m getting the following:-
28EC00 Exhaust pressure sensor upstream of the turbine, plausibility: exhaust gas pressure upstream of the turbine is implausible to ambient pressure in the wake 2AB600 Exhaust pressure sensor upstream of the turbine, plausibility: Pressure upstream of the turbine too high (not plausible to boost pressure and ambient pressure) 36F500 Intake air system, plausibility (preliminary stage 3): Check › for large leaks (pinpointing phase with power reduction) 290900 Air system, air to EGR mass flow plausibility: measured air › mass too high compared to calculated air mass 284000 Lambda probe, signal Nernst voltage: interruption Anyone have any ideas on any of this? Seems too coincidental for it all not to be linked? Thanks again. |
Appreciate
