Yep. That's it. Wicked replaced the ICV and fixed the issue so that's good news for everyone.

Same here. Only difference I am using G-Power supercharger but also w/ cold start delete. First minute after start is fine then the idle starts to fluctuate as seen in Matheus vid. After another few minutes or the car starts to warm up it is working fine.

Looking forward to the results of replacing the ICV.

Just used the BMW diagnostics tool (Rheingold) to check my ICV and the system test shows that my ICV is totally fine. I have also checked my TAs and they are also fine.
Would like to ask someone of you to perform this test too. This might be an indicator for a defective ICV or not.

I have the same issue following installation of an ESS 595 kit. Bank 2 throttle actuator just went and i'll be replacing this weekend. Can update the thread with results after install.

That's exactly what mine would do then eventually it would die out.

Pls do. I'm still checking on ICV price if it'll be cheaper to source local or US.

Did you check your ICV with Rheingold? Would be interesting to see if there are similar results

It would be but I don't have Rheingold or any other scan tool.

Well, I replaced the faulty throttle actuator this past weekend. While not definitive since it was an intermittent issue, I can say that the fluctuating idle has not resurfaced since. I'll update this thread if the issue comes back.

^Did your car throw any codes?

Cleveralias · 10-17-2018, 09:25 PM

^When? Not when it was just having the idle fluctuation while cold, but eventually it started throwing a code for the bank 2 throttle actuator which came with limp mode. Initially I replaced the gears within the actuators but the code came right back so I replaced the whole assembly. No codes since.

It's hard to pin point what to replace or what actually is causing it as no codes is poping up for this idle episode..
