curly glowing

when I went home this evening (the last 3 km it goes uphill) and then put off the fox, I noticed a red glow (red as with a cigarette) behind the radiator grill (under the hood). when I opened the hood, what glowed (the curved one?) under a sheet cover. because I don’t know myself so well with engines and especially with vw motors: is that normal? or do I/my car have an arges problem? did not find anything in the operating instructions. however, I don’t want to know anything about myself either: is that normal? or do I/my car have an arges problem? in the wekrstatt embarrass. guaranteed I would have spent another month on the fox. what should I do? please help! thank you! gruss -pocky101-
