My question to you would be how often do you use your stop start??
To be honest, I wouldn't even know how to disable the Stop/Start on our TA. It now operates as it should, so when we stop at lights etc it does its job.
People go on about bigger batteries, well that's fine, but we've got what the car came out of the factory with and clearly it does what it is supposed to and I have no intention of forking out money for no reason when I have a CTEK charger that can recondition or provide a top up over a few hours if required.
If anyone therefore knows the procedure to disable the Stop/Start on our TA, please feel free to divulge the info, but as the system now works exactly as it should, I doubt I'll need to actually consider disabling it.
