ecu miscommunicating issue
I have been experiencing sluggishness with my car for a while now. Here's what my indie mech told me: the c36, c43, and e55 have recurring issues with the ecu miscommunicating with various sensors. In my case it was one of the o2 sensors. No cel, but he did pull a code for a loose o2 sensor connector. He checked it, and nothing wrong. Then he hard rebooted the ecu (not resetting with the gas pedal). He said this miscommuncation happens due to the hard acceleration and braking in these cars. He also said there's no perm fix. Just if I notice sluggishness, pull the codes and he will just reboot the **** for me for free. This semi makes sense to me bc I trust my mechanic, and also he did replace the plugs, wires, etc earlier this year, and also rebooted the ecu. After I got the car back it was an absolute beast, but then got sluggish again. Now after the second reboot, the car kicks *** once again.
Anyone else heard of this?

It seems the only real ECU reboot can only be done using the Star sytem. All the rest are placebos

Yes, that's what my mechanic told me. He reboots mine with Star. I just am a bit dismayed that this is a recurring issue with my C43, with no permanent fix. Oh well. She has served me well for all these years, so ill cut her some slack in her old age!
