We had our 10 month old ZS serviced at our local main dealer - Tomey Basildon - end of November. 1st Year service and Comfort 2 update (Paid for). No indication if the car took the BMS update. Maybe part of the first service?
Since the service the feeling has been the range is much lower than before.
Initially I was putting this down to the cold weather. Having read the posts on the FB page, I do believe there is more to it than just the weather. So started to collect some data in the last day or so.
Charged the car overnight using our Home 7kW Rolec charger before using the car for a 66 mile round trip yesterday. Noted when we went to disconnect the car, the MG symbol was still illuminated (Not pulsing) so if I understand correctly this means the battery was balancing (Correct term?). Started out drive with 133 on the GOM. Driving cycle was about three quarters Motorway, rest B roads up to 50 mph. We did drive about 70mph so, yes, heavy footed on the Motorway. Drive cycle gave 2.8 miles / kilowatt. Returned with 34 miles on the GOM. Two further short trips during the day, one 3 miles and one 13 miles. Wife commented on the 3 mile drive, GOM dropped 10 miles in one go. After the 13 mile round trip, returned with --- and putting the car on charge, 4% left on the battery.
So mileage for the day was 82 miles. Battery not fully balanced.
I did not do the last two drives. Budgeting 2.8 miles per kilowatt overall for the day, and assuming the battery was fully charged, I would have expected about 124 miles instead of 82.
Coming back to the overnight charge, monitored overnight last night. To charge and complete balance - MG light off, was 10 hours. Seems a long time?
I would welcome thoughts if members believe I have a issue here and if so what other data should I collect before contacting the Dealer?
