Thanks for the advice during the issue.. but here is the post a lot wanted to see.
So its now late afternoon and after a café (espresso) in town I have a 1.6mile drive to the hotel... about 30 seconds in. An alert on the dash fires saying "Power Restricted Mode" along with an Engine management light (this has happened to me 3 times in the last 2 years in different cars) so I know I should stop the car asap but get to a safe place to do so.
I get to the hotel car park, park-up check in and let my wife go to the room.. go back to move the car a few mins later and... nothing! So as this car does not have an assist call button like my others I google the breakdown number and find

+44 1603 370023 IF OUTSIDE THE UK
I call the number (its the AA like most in the UK), they go through all the details and then when asked where I am I explain France. This triggers a transfer to another department based in France.
I then go through the same details and the person asks for the make and model. The reaction is... a lotus - I have never had a lotus call before. Let me place you on hold while I go find out. 15 mins later the person comes back and say; lotus are not covered by this service and I would give you the number to call but that will just bring you straight back to this number (he clearly had googled the same as me). He continues "I have found out that lotus have a very unique recovery contract that is not covered by AA France - I will transfer you to the correct company"
After a few attempts to transfer and about 10 minutes he comes back "it appears no one is picking up - I will keep trying for you and get them to call you back - as you are in a safe place is this ok".
TBH I am relaxed about it knowing that I will not be using the car again that day but it is about 5pm now and agree.
2 hours later I call back - Turns out the Guy from France AA is still trying to get through. We agree for him to email them and I will check back in the morning... clearly this was not ideal but by this time I'd had a few beers and was super chilled in a nice hotel with a reservation at a great restaurant in 30 minutes.

BTW if you are ever in Saint-Gervais-Les-Bains I really recommend
Le Serac Restaurant
After dinner, the realisation of a ~650 mile drive the next day started to kick in and the car was not working... I would say this triggered a middle of the night unrest and I woke-up and started to dig. Obviously in about a 4 hours I found a handful of people (this forum is amazing btw) on what ti could potentially be, other people with the breakdown issues etc etc.
I have had the joy of working in Automotive manufacturers for ~15 years. I reached out to a few people I had not seen in a number of years that might be able to help... at 8:30am I get a call from Lotus Warranty and explain my situation.
We had to checkout at 11 so I talked to Lotus about the risk and decided if I could start the car I might be able to drive it to a lotus dealer. 10mm spanner is helpful indeed!!!
So I get the car started and no engine management light is present. The guys at Lotus was super helpful. They continued to take charge of the breakdown part (just in case I did actually breakdown again).
Lotus took the symptoms down and acknowledged that it was a likely issue as they recently released 2 potentially impact module updates. It looked like Dijon was the best dealer for me to go for...
I headed off and the car felt fine to me! Lotus called me every hour to check everything was ok and to give me updates. confidence was high in the car now... and I had left something in Evian-Les-Bains so I had the terrible pain of driving back over the mountain !!!! The weather was great and the drive was amazing.
I have to be honest that I did not push the car as hard though as wanted to get to the dealer in 1 piece. Lotus was concerned that if I turned the car off that it would not start again so I was a little nervous when I stopped for fuel. The car is running in the picture
4 hours later I arrived at Lotus Dijon... in the rain... WHAT A DEALER I wish my dealer was like this one. A proper lotus dealer not attached to anything else and is next to a race track where they tune lotus cars all day long. It was a joy to walk around.
The new software (thats not available on a recall or anything yet) was installed - took about 45 mins. During which I got to look around the service area.
They even maintain their own race team here:
Car now flashed and ready to roll to the last train of the day back to the UK.... The sun even came out!
