Can you clear them and see what comes back in Lot of Landcruisers now sold
Audi TT 240 Sport now sold for.
RRS 2.7 HSE Now sold for.
RRS Autoibiography 2012
Defender 300tdi 90

I'd put a brake switch and 2 brake bulbs in the car

Very common issue

I cleared the codes ok last night I will get a switch and bulbs today and fit
I will also check for codes when I get home from work
Thanks for the replies
Cosmo

A lot of these alarms can be due to a battery not holding it's charge too. I would do Disco Mickey's checks that tail lights are working OK as this is the main cause of alarms in RRS1 and Disco3/4 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

That's just what you're supposed not to do.  Visiting from DISCO3.CO.UK

Fitting the switch the way I did has it damaged it

I believe it may/will have. I have to say, I've never looked into, or thought about, why though , but it is an observed effect.  Visiting from DISCO3.CO.UK

I've just had the same warning message today too

Transmission fault
Special features disabled
Suspension lowered

If I turn the car off then turn back on the message transmission fault appears but then car drives ok and if starting again no transmission message appear again.

But after driving a few miles up the road all the above warnings come back with a yellow exclamation mark flashing near the temp gauge

Cosmo15555 - Did u find out what the fault was or was it all sorted after changing brake light switch? RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED

I fitted a new switch on Monday and so far so good
If you have a Brit part near you get switch from them as dealer is £25 and Brit part £11 so big difference in price for same item
I found this out after buying 2 switches as fitted first incorrect
Second time I fitted not moving brake pedal
Hope this helps

Brill good to hear

Im hoping ill be as lucky as you with this small fix as it was quite worriying when the warning messages came up while travelling down the motorway over 200 miles away from home  RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED

Fitted a new switch today without pressing the brake pedal but warning came back, all brake bulbs are working fine too, any ideas what to do next  RRS SUPERCHARGED, 22 INCH ALLOYS, JAVA BLACK, FULLY COLOUR CODED

The Steering Angle Sensor (SAS) calibration sounds like a strong possibility.

Maybe worth changing the brake bulbs as a matter of course (make sure they're decent ones), as they can be fully functional, yet still be the culprit.  Visiting from DISCO3.CO.UK

Check for +12v on the red wire going to the switch
