Hi there folks, just purchased an xantia td 97 I have just been testing the suspension out, because the back looks very high and the front stayed up,, when i lowered it to normal hight. when i lowered to the bottom both front and back went down fully. Then back to the normal position and front went then back(still unuasally high) and on came a orange light on the dash which looks like a car on its side with a gear stick motive under it...and the air bag light flashing on the left.. has anybody got any idea what this is >>?????
