Astra J/GTC
Hi all. Newbie. I have a Astra 1.4 turbo 2013. 25000 miles. Had it for 3 months now. It's got a harsh sounding rattle when you start it up when it's warm. You only hear it for a second until it fires up. Been back at vauxhall they said igt was a stone in exhaust? Sounds a bit lame as it's still...
