sus

Hi Bought a 2000 E320 cdi estate for a cheap run about, car is nice, good spec, full history etc Noticed these faults on the car wondering if someone can help? 1) Brake pedal feels springy under my foot. Cruise control doesnt work either, and occasionally the ESP warning triangle flickers...

I have a 560 with hydraulic suspension, What do I need of a doner car to change the suspension for normal shocks and springs and is it a difficult job to do?
