Hello i was driving the other day and notcied my ses light on. So i went ahead and hooked it up to a dtc trouble code reader and it popped up a powertrain code which is P2096 post catalyst trim lean bank 1. Not sure if this is caused my fuel cap not on right or i noticed that i have a slight crack in a tube that connects to the air filter/maf sensor to the intake part of the motor. So im not sure where to start... Thanks for you help

2001 BMW X5 3.0l miles: 83000

I would replace the boot and reset adaptations
then drive and complete monitors
part number for the boot is
13-54-1-440-102

went in to bmw parts dept. and go that intake boot and installed it myself took about an 1 hr to complete drove it for 30 min and came on again think i should look into the intake and exhaust cam sensors?

what is the fault for this time?

Hi,
the code it read was the same p2096 post cat bank 1 to lean

this may need a reflash of the DME
there is a bulletin for this fault
there may be other issues involved
I will get back to you at end of business tomorrow
so I can check the bulletins

the reflash may be required for this problem.
without seeing the car myself it is difficult to be sure.

Oh ok... Well thanks for all your input...Will try to reflash

Hi there well i replaced the exhaust cam sensor and the code is still tripping...In my x5 i do not have navigation is it possible to still do a reflash:?

what is the mileage on the car?
