E63 CEL on, P0191, P2187, P0451??? Please help
Hi, everyone!
I have e63 2007, from this forum find out that M156 engine has common problem with intake manifold gasket leak and purge valve. Does anyone know what is wrong with my car or had the same problem? Check engine light is on, P0191, P2187, P0451. Car drives good, powerful, no misfires, only little rough when idling Please help! Thank you

I had a similar problem with my car , though I have a E55 not E63. So took it to the dealership and they looked at and gone. They told me that there was an ECU update for that code and the update increases the permissible limit and the thresholds. My tune and everything got deleted but the engine light went away as well.
But I have an E55 so it could be totally different

Update
Finally, I found and resolved the problem with "Check Engine Light". In my case it was bad PCV Valve / Breather hose (part of emission system), part# A156 010 03 70 ($90.00). In regular maintenance routine, it needs to be changed every 70,000 miles.
Maybe this information will be helpful who have similar problem with M156 6.2 engine
Symptoms:
If the faults codes P0191 P2187 P0451 present, CEL is ON, can be white smoke from exhaust after cold start, no misfiring, engine oil around the PCV Valve, engine oil dipstick popping out, part# A156 010 03 70 must be replaced.
In some cases, it can be the Purge Valve, fault code P0444. Check if it pulsing by holding it, you will fill the vibration if it working good.
Thank you everyone for help!!!
