Afternoon all hope all is well disco 3 on a 2005 tdv6
The wife disco seems to be upset went to a well known tire garage and it’s had the yellow suspension light on for a few day
Now for the fun bit 3 hours later lowered it back to the flor and went to put it on the tracking machine
and problems the bum was right up and the front right down now got a RED sus light and the lovely phone call from the wife
I have plug it into my obd reader and got rid of most but I have got two live codes which are
C1aoo control module
And uo421 invalid data revived from ride level control module
Can you please help on where to start check compressor and in res seems to be ecu behind the dash or the valve behind the wheel arch
Any help much appreciated
Manny thanks
