Yeah that's what I thought, they specifically said the below :
"Normally missing a service would invalidate the warranty on other brands however with MG your warranty is still valid. However, if an issue occurs and its deemed to be something related to the servicing of your vehicle it may not be covered but this will be investigated thoroughly." A bit vague as you say and if it came down to a more expensive warranty claim, I'm sure they'd probably find a way to link the issue to the missed service, but perhaps for smaller stuff like the door locks, they cover it.
I've booked the 2nd service / warranty check in, a week from Monday. Then for the next one, I'll probably take MG's servicing plan to keep the record in tack from this point, seams reasonable, if not as cheap as an independent.
A quick further question I have :- I topped the battery up to 90% today, and after the car was giving a 174 miles range, where as I'd expect to get around 211 miles at 90%. Is that because the car is predicting the range, from the way it's been previously driven, or factoring in the cold, or other variables. I wouldn't have thought there would be much battery degration yet, with 2.5 years and 20k miles. Just thought at 90% I'd be getting more around 200+miles. Hopefully nothing to be concerned about, and hopipng to make it from Leeds to Birmingham tomorrow morning on this charge.
