Hi, new member today after buying a c8 last week. It's a 2007 2.0i petrol auto It was an eBay buy so you guessed it, have found issues already! Just had thermostat, water pipe, CV boots, exhaust fixed but a couple more issues I'd love some guidance on 1. Temp - car gets to 90 degrees but takes a while. If I then park up for an hour and on return it's pretty much back to 60 or 70 degrees. Is this normal? 2. I have a loud buzzing noise from front right of engine bay as I look at car. If I turn steering the buzzing noise alters so I'm guessing this car has an electric hydraulic steering? And electric motor is buzzing? Anyone know much about the steering, how hard to replace, if this is a sure sign of impending failure? Google has little on these cars! And lastly, how the heck do you do anything is that engine bay?? Cheers for any support
