great update, thanks for replying. I wanted to add that for my vehicle I did experience the hesitation the other day briefly but only for a second. It has been a while and previously the car would be having this issue for a few minutes of driving. Seems once and done now so itās definitely better.My update & guide for anyone interested:
So as i previously mentioned, I went into Listers Stratford-Upon-Avon and spoke to their Supra tech Chris. I decided to go the official route and state the real issue. Obviously he couldn't recreate the issue as its so random but suggested due to my safety concerns that he raise a ticket with Head office who would work in tandem with BMW on the issue. My car was there for the best part of a week while they went back and forth.
I was told my car was on the latest update that Toyota had available: S18T-21-03-XXX (last 3 digits unknown). After the tech spoke with head office and BMW they confirmed that BMW had encountered the issue on the Z4 and had a much newer software update available but Toyota dont have access to it. The BMW Engineer worked with my tech to update my car with the BMW module updates bringing it to software version: S18T-23-07-505.
As of writing this I have no idea if this has indeed solved this issue but have an appointment with Toyota in a couple of weeks to report any findings. Based on this info and I'm sure other cars having this fix issued to them Chris was confident it wouldn't be too long before BMW passed this set of updates along to Toyota for official release. As you can see its a huge software jump in iterations so fingers crossed this fixes it and gets issued for everyone to benefit from.
Sorry for the long post, I just wanted anyone chasing this to have all the info possible. If you go in for the update right now I think the truth is the tech will be correct in thinking your car is on the latest update but in actual fact Toyota dont have it.
I wonder if what youāve had done is the complete solutionā¦ā¦ could you possibly find out which modules were updated specifically? I will be showing my supra tech this post now I have briefly experienced it again, Iād like the issue squashed.
