I have a problem with my 2.0l GTI, when i start the engine the starter motor makes a whirring/grinding noise which lasts about 2 seconds. I've done some research and it's quite a common apparently, And it means you either need to completely replace the SM or just take it off and give it a good clean and lube before putting it back in. Problem is i know nothing about cars/mechanics. So was wondering what i would be looking at to have this done by someone? I'm in Bristol if anyone can be recommended.
