ESP light constantly on
I have owned my Q7 for just over a month and it has been perfect in all conditions. Even Mpg was better than I expected.
Hopefully this isn't an expensive fault. It has been fairly intermittent but now the ESP light just stays on constantly no matter if I press the button. I hope it can be a simple fix. I had the code read and it came up with 00814 - solenoid for brake pressure - open circuit. Cruise control still works, however if I go over 35kph the air suspension warning light comes on and it stays in automatic mode with the rest of the options greyed out.
Many thanks in advance for any help.
