Bmw 650i GC drive train warning sign

daniel650i · 05-08-2022, 02:41 PM

53k miles on it and woke up this morning to this warning sign that I need to get my drivetrain checked out.
Car idles fine around 650-690 rpms
no shaking or limp mode
able to switch from comfort to sport+
no power loss
I went to my nearest auto zone thinking I could pull any codes but the scanner came up with no codes read
oil changes every 5-6k miles

The car has vrsf catless downpipes and a bootmod3 stage 2 tune.
Fuel injector and one step colder spark plugs were replaced at the installation of the boot mod tune. Around 35k miles.

never ran into this issue and I know these warnings for our vehicles is like playing jeopardy lol. I have a service appointment at bmw tomorrow but this is literally giving me anxiety!

I guess I don't know for sure what scanner Auto Zone uses these days, but you need one that reads BMW codes, not just generic OBDII codes.

Yes I was able to pull up a 20a608 code through bootmod scanner

So I used boot mod scanner to pull up a 20a608 code that states "turbo coolant pump/actuator blocked"
checked my secondary coolant reservoir and the coolant is low.
Gonna fill it up and hopefully BMW will give me a free motor since I know my motor will fail their oil consumption test

Copy and paste your fault code at this site…follow the links to see info about the fault code you searched for…don’t forget to click on the VIEW links to see possible causes & solutions (click ALL of them…they can give different info): https://bmwfault.codes/

The site accepts generic OBD II “P” codes (aka DTC “diagnostic trouble codes”) as well as BMW “hex” codes.

Any update on this. I have recurring 20a608 code after putting in 2 brand new turbocharger aux pumps. Not sure what to do next. Turbochargers are new too. Smh
