How expensive is it to convert from airbag suspension to springs? Is it necessary? Td5 model V reg

spring kit about 70 quid, either fit your self = time or get someone to change = labour. Then car needs to be plugged into tell system it is not on air.

I have owned both air is best , That's the one I have owned for the last 11.5 years , only had to replace air springs once.

Hi guys,
and I have. My name is George. I have a TD5, that I took, recently, from Holland and I have trouble with the air suspension(self leveling suspension) on the rear. the car was parked for 5 days and the rear end(both sides) is down, almost touching the wheels. I tried to start and activate the lift the back function but the led remains on until I stop the engine and when I start again the led on the dash board, that signals that there is a problem with the self leveling suspension, stays on.
Can anyone take a wild guess and tell me what can the problem be ?
Thanks
