I purchased a Peugot 308 1.6 HDi in October 2015 from a dealer. I purchased it with 24,000 miles on the clock and 12 months warranty. I have covered just over 10,000 miles since purchase and it has developed a gearbox problem. Whilst driving on the M4 doing around 70mph it decided to jump out of fifth gear. When I put it back and applied power it would keep disengaging and going in to neutral.

The warranty covers this and its going in soon to be stripped down by the dealership. The pre-assessment check told me it will need a new gearbox. The warranty company want photos and a report and I'm now afraid they are going to worm their way out of it. Have you come across this before and how should I go about this awful situation?
