Sorry, but I do not catch the point with the IVM, EWS or how is it called.

Do you mean, that this can cause the issues, with what I am dealing with or? :)

N62 misfire

IVM controls the voltage that controls almost everything so when that fails it makes it look like other parts fail. It can just be the IVM. EWS not related I was just making example of the weird noon matching acronyms

Is there some method to test the IVM without replacing it?

Not without really digging into it. Here in the US it's ~$95. I'd just replace it. Probably going to do mine preventatively soon.

I have found this thread by googling: IVM or why my engine runs sluggish??? N62 applies to ALL cars with it. E53/e65/e60/e63/e64/e66 | BMW LOGIC7

Seems that the common issue is bad solder contact in IVM, luckily my all day job is related to PCBA manufacturing so I will check it out myself first before replacing it :)

I’m having the same issues except I have 3 constant code of cam shaft outlet cam shaft inlet and vanos bank 2 . I swapped vanos from both sides. Pulled the valve cover and replaced the cam shaft sensor ? Any ideas

I've fixed plenty of things including both of my keys with reflow.

The point of swapping is to determine if the fault changes sides. You said swapped vanos which requires removing the valve cover and re-timing the engine. I think you means vanos solinoid.

If you swapped parts and error moved that is the culprit. If you swapped parts and the error didn't move you have work to do.

There should be FOUR CPS on N62. You said you have errors on both CPS left side. I would replace both with OEM grade don't use discount CPS.

Vanos error could be ripple effect but if you swap vanos solenoid banks you can determine that.

I would swap all four solenoids and replace the CPS in the bank with the error.

I am getting the same codes after the switch and I also check the internal chain on that side no play .i also replace the cam shaft sensor
