After owning my A4 170 quattro for less and 2 month iv already had the dfp light on and to my surprise after a quick wash today i noticed at least 2inches of water sloshing about around my battery! Hard to see in photo as water is see through... but after about an hour of rinsing my microfibre cloths out i finally got it out, iv stuck two cloths back in and wedged them under battery and around pipes to catch anymore water but i think its something to do with not having the full covers over the battery? i only have the left hand side part. hopeing i dont have anymore collecting here. Oh and iv also noticed a chip in my windscreen! arggghhhh!!!
