Too many warning lights...

[CraigMillwardCroft]

Just changing tyres at the circuits brought my lights on did checks all good pressure, so just ignored it from then on after journey back from SPA all went out and stayed out.

how do you reset the red light?

every time i press the button with the tyre symbol on (left of sport button) the red dash indication goes out but lights back up several minutes later....

idiot guide to keeping the red light out would be great.

Turn ignition to 2 (i.e. power on) or start up the car (either way is fine)

Hold tyre pressure reset button down until the symbol on the dash turn from red to orange, let go of button - drive off and it'll reset.

any advice would be appreciated.

Might need to run a soft reset of the wheel speed sensor ...

Take the car up to over 35 miles - put into neutral and hold back both +ve and -ve paddles on the steering wheel for about 10 seconds (there won't be a feedback or light to tell you it's done) - let go of both paddles and put car back into gear - done.

It's in the handbook - should be done if you've changed tyres.

I wouldn't know Tom as I don't have the GT1... just a pikey Snap-On ETHOS.

My steering wheel is also cocked to one side... I hear it could be rear road trailing arm bushes? Anyway, I'll book her in soon and will let you know...

Hello guys,

Quite right in saying that the pressure sensors are the most likely cause of these warning lights coming on. There are 2 sensors on the master cylinder.

As quoted below the only way to tell which one is causing the problem is to use a diagnostics and disconnect a sensor to see which fault code shows as currently present.

will either list them as 'Pressure sensor 1' or 'Pressure sensor 2', Or fault codes 5E20 & 5E21.

The warning lights will come and go as the fault is present/not present. This differs from EML light for example, this will stay on unless the fault has not occured for 3 ignition cycles in which case it will then go out. Airbag light will stay on until faults are cleared by diagnostics.

As for a steering wheel not straight, could be a number of things but its usually an issue with the front axle, not the rear.

We look forward to seeing you down at Munich's to get it sorted.

I had DSC and Handbrake light come up on dash this week. GT1 showing 5E20 Pressure sensor 1 when checking quickly. Just need to unplug and find which one it is.

Pressure sensor 1 is closest to the firewall...

Unplugged both my pressure sensor connectors and noticed a very small amount of fluid around them both. Decided to clean both for good measures although only one was showing as faulty, allowed to dry, plugged back in, cleared fault codes, test drove and haven't re-appeared (yet). Hopefully problem solved.
