Hello, I have just got a new exhaust put on my car, it came back from the shop and I'm getting a error message on my dash saying "power steering" also, my speedo is not working. Well back when I replaced the clutch a few months ago I had the same problem, I wiggled the ecu a little and everything functioned perfectly again, well this time I am not having the same luck, I disconnect the battery and then connect it again and the "power steering" light goes off but still no speedo, any help would be very much appreciated. Thank you!
