Hi, I have Octavia 1 1.9 TDI from 2004 with 404.000 km. Lately I noticed that real fuel consumption ( from refueling to next refueling and then calculation consumption ) is higher than my board estimate fuel consumption. Difference is aroung 2 liters per 100km. Now I went to fuel station, computer says 5,0l/100km from last refil and my calculation says 7l/100km based on filled fuel and kilometers driven. With OBD11 I scanned car for error codes and there are none errors on any module. Injection deviation on idle is max +0,35 to -0,40mg/H on two injectiors, other two are around -0,10mg/H to +0,10mg/H. Car is driven in city on short distances but I don't think that shoud be reason for almost 30% inaccurate board fuel consumption. What could be reason for that much difference in board and real fuel consumption? Thank you.

Can you please describe how can i remove back cover? I tried to remove back cover and can't find it under the hood and behind lights. Can it be removed without extraction of light?

Dear all, Car is 6 month old and now in winter time I noticed mist in lights after I drive it. It doesn't matter if I drive it 15 minutes or 2 hours, mist appears and it takes one full day of not driving a car to disappear. Is this normal or should I contact dealer? Thank you!
