[BmwE703.0si]

I have a 2007 BMW X5 3.0si. My car revs it self. When I clear the codes the car idles badly for about 3 seconds then the engine light comes on. I start the car again and it doesn***8217;t idle badly but every few seconds it revs up to 2000rpm and idles ok.

Codes come up with 4 oxygen sensor activateed, Both Vanos Solenoid, Low oil and air leak.
I replaced both Vanos and only showing port one as an issue as retarted cam shaft p0021 code.

Previously I had misfire on cylinder 4-6. I changed the coil pack and plugs and no misfire now.

I***8217;m thinking the DME is bad or something else which I or 3 people with diagnostic tools can***8217;t figure out.

What tool are you using to scan the car? It matters. What codes are you getting?

The car has 4 oxygen sensors: 2 before the catalytic converters and 2 after them. Your tool says all are bad?

At first I only had 2 o2 sensors come on but I had 2 Vanos show on the scan. When I replaced the 2 Vanos I only had 1 Vanos show in port one but all 4 o2 sensors came up.

At first we used a Bosch scan tool the second was WOW scan. BMW scan only tells me the fault no codes
