“Hello pleasant neighborhood volt tech right here! The noise is coming from the electrical brake booster meeting when the booster valves are on the idle place. This is the reason it goes away with any pedal enter. This was truly pretty widespread on Bolt EVs, however the volt makes use of the identical Bosch ibooster meeting. We used to switch the boosters for this however GM just lately launched a TSB to cease changing them and new software program shall be accessible first quarter 2021 to eradicate the noise. The kicker is that the TSB solely applies to the bolt. I am not but positive in the event that they will even have new software program for the volt or if it’s going to want substitute. The excellent news is that it is solely a noise, it will not impact brake operation in any respect.”
I interpreted this to imply the ‘tsb (software program replace) could cowl the Volt at a while’. Did I miss one thing?
I attempted to look fb for the thread Jaryd posted this in, however my FB looking out acumen is fairly off. Anybody have higher luck?
