I would definitely make formal representations, the council's evidence looks weak and it is quite odd that the photo of the sign was taken 30 minutes later than the photos of the car.
The one thing you must not do is alert the council to the weakness of their case. If you attack the photos or the signage in the representations, they'll know to prepare a water-tight evidence pack for the tribunal. The map you've put in post 12 is probably better evidence than I've ever seen a local council put in front of the tribunal (I suggest you delete it). While you cannot lie or mislead, you are not required to incriminate yourself (people tend to do this a lot for some strange reason).
There is a fair chance the council's evidence at the tribunal could fail to prove a contravention, though of course we can only go by past experience and cannot give any guarantee on the outcome.
Therefore whether you wish to pursue this is not is very much down to your attitude to risk.
Are you the registered keeper and do you have the V5C?
Thank you for all your advice cp, Im unable to delete that photo now, if any of the admins can do so that would be appreciated
