Now this is annoying!

Oh dear. It's so you can't sue Suzuki because the car veered into a bus stop full of grannies because one of the tyres sorry tires was soft!

I have chased this with Suzuki and the technical feedback is that it is not configurable from any menu, it is what it is. It has been lodged with them as being a problem on vehicles such as Jimny where "lowering the pressures" is a standard off-road, snow, sand driving technique.

I have spoken to the garage supplying our Gen4. They say it is a total pain in the *rse and at this time of year with the temperature dropping they get 15 vehicles in per week with the issue (the average Suzuki Celery/Swift customer cannot top up their tyres!) and it keeps their work experience teenager busy. It should have a wider leeway. They used to have a dealer only adjustable parameter on Renaults for this very reason.

They have been looking into it and noticed on a Swift that the new update of diagnostic reader software from Suzuki has displayed a whole series of new parameters they have not seen before. They are going to plug the unit into our Gen4 this week and take a look at the deep parameters that have been enabled.

The dealer also said a simple way to get the light to clear on topping up the tyre is to have the engine running whilst inflating the tyre.

I spoke to the MOT tester as well. TPMS light on is not a fail, the failure is where it is flashing that there is a fault with the TPMS system, a low pressure tyre is not a fault. So it could be left.

Where people may have separate summer/winter wheels, fit "cloning" TMPS sensors to the spare wheel set, the car will not know the wheels have been changed.

I will update if anything comes from having my Gen4 read.
