Hi All

New to the forum and hoping someone can give me some advise please..

Problem: ESP Light always on

Car: 2006 Vectra C 3L V6 Cdti Sri

Symptoms: None Really as car seems to be driving as normal and even Traction control seems correct although Cruise control no longer works

Background: Recently had new bushes fitted to both rear wheels and ESP light came on next day. Cruise control was switching itself off at times although not always

I have limited knowledge on cars (apart from driving them) and was wondering if there is anything obvious, apart from checking the fuses, that I should look for? I have seen some Tech2 plug in devices on Ebay to read codes and does anybody recommend one? Many Thanks in advance.
