I have just replaced the clutch on my C4 Grand Picasso 1.6 hdi. All went ok and is working fine but after restarting the engine i have ABS , ESP and handbrake faulty warning lights on the dash and the handbrake will only work manually. I have checked and as far as I can see everything is reconnected. All was working before the clutch was replaced. Has any one come across this problem before. Is it a case that it just needs to be reset?
