Strangely, following posting on here, I went to my B6 and although the bonnet popped, the safety lever had seized solid. I don't mean a little but it felt as if welded in place and obviously, it wouldnt open, and I needed screen wash.
I had to remove the front grill first using a 3mm insulated screwdriver blade, covered the tip in insulating tape to avoid damaging the paintwork, Then with the assistance of trim removal tools, started at the top left of the grill, and prised it forward until I could get a trim removal tool in there, between the edge of the bonnet and behind the grill...
Then moving along in one inch sections, I forced the grill out enough for another removal tool to be Inserted... when at the top right of the grill, with the tools in place, I managed to lever the whole top of the grill out, then simply lifted the plastic out of the aperture.
Then to the hinges...
There are two hinged sections which had seized solid. With a 750ml tin of a very well known penetrant, Plus and the american name for petrol, Not the WD one plus 39, and constant spraying on the hinges at the same time as trying to move the lever out from the grill, little by little it moved... It took ages for the first movement but it eventually shifted a tiny amount, but that slightly increased little by little and it started to free.
20 minutes later, it had released completely, and felt like new... I had used more than half of the tin and now have to put some thin oil on the hinges, then will get come waterproof grease and work it right into the hinges, the thin oil will assist.
New cable next week as the way my week has gone that will now break....
Oh forgot to say, the grill went straight back in, bottom first then push the top and job done!!
