Cheers, I can't say I've noticed the movement when turning on the engine.
I've emailed the seller now to see what can be done
I just wanted to make sure that Xenons hadn't gone down drastically in terms of quality since I had them last!
I'll hopefully get it sorted asap.
It's a 14 plate car, why are you bothering with the seller? Drop it into your nearest vauxhall main dealer, ask them to fix it and take a courtesy car away
