UK Auto Repair Questions?
Can you describe if possible what it sounds like? ie: - squeeling? rattling? metal to metal noise??
When does it do it mostly at start up when cold or all the time?
What engine do you have?
Well i cant see it being the steering because being a 2010 model you'll have the Corsa D which uses a electronic motor assisted steering column...If its squeeling nosie as you describe? ideally you want to be having the noise occuring and have a listen under the bonnet..if its from the belt side then try spraying the belt with some water.if the nosie instantly stops or reduces then you prettymuch narrowed it down. then switch the engine off..then inspect the auxillary belt..if the ribs are cracked..then replace the belt..if you can remove the belt and check each of the pulley that belt run on to ensure nothing feels seized or binding up causing the belt to slip....its also known for these engine to suffer timing chain problem..but unless it an actual rattle that you can hear behind the timing cover..of course check your oil level..then it say the best logical area to check first is the belt/pulleys on that side first..hope this helps
