I haven't exactly been using my car much of late for obvious reasons. Back at work now and driving in yesterday I noticed an unusual smell in the cabin when I pulled up at a set of lights. Basically it smelled like a chip shop! Any guesses as to what it might be? I thought I'd pulled up behind a diesel that was running on veggie oil. I've had the bonnet up and can't smell anything similar, there are no obvious leaks and it's not the clutch. I've even checked for a potato up the tailpipe. Any ideas?
