Engine braking using 1st gear! 
Ouch, poor car.
Sorry, no help on the technical side. But 1st gear is much lower than 2nd, so generally not a good idea to use it for engine braking IMO.
Good luck, my advice is to take it to an independent specialist. Just use main dealers for keeping the book stamped at service time.
