Tesla Supercharger Issue MG5 LR

Booked my pre-facelift 22 MG5 in for next month - 3 year service & MOT.

I asked about the update and even said that if it couldn't be done under warranty I'd pay for it (after all, it's not the dealer's fault and life's too short to spend time arguing the toss).

After the receptionist checked with the service manager and got back to me, she said they were going to get on to MG to try and get it done under warranty, but if not would do it for the technician's time only - worst case scenario a hundred quid if it takes an hour, but probably half that.

I don't have high hopes of getting it done under warranty, but at least they seem to be trying.

I’m curious about the model number of your EVCC. It’s easily accessible next to the battery, as you can see here: MG5 Supercharger: FAQ 2 - What upgrades does my MG5 need to use a Tesla charger?. Since our cars are the same age, I thought you might be interested.

Or, if you’re an owner with this model number, I’d love to hear from you. I asked MG about it, and they were very helpful, but they couldn’t really give me a definitive answer. They suggested that some larger dealers might have experience with this issue and be able to apply the software update. It’s a simple update, so it shouldn’t take more than 5 minutes to apply. However, it seems like some cars will take the update and some won’t. My nearest other dealer is Mill Hill, but they didn’t know either. Until I get more information, I’m a bit stuck. Even MG agreed that £360 just to upgrade for a Tesla charger isn’t worth it.

Sorry, I had a good look but couldn't see any numbers without taking the whole engine bay cover off which I couldn't be @rsed to do.

Anyway it all got done yesterday successfully, and no surprise I got charged for the technician's time which came to about 70 quid, so not bad to have the peace of mind it's all done.

I have no idea where my nearest open Tesla charging site is to test it out though.

Well done Jim pity about the £70 but you have it now. So go on to google type in "Tesla Superchargers open to all" for a map, or download the Tesla spp; then you need to set up an account for payments and you're done. Simple.

Your nearest is just south of Durham at Bowburn so not far.
Unit 1 Low Main Court,
Integra 61 North
Bowburn DH6 5NP

Click the following link to see where all open to all sites are without using the app. You can move around and zoom in and out easily, making it easier for planning, then use the app, (you will need it set up with a payment card) to get there and start charges etc.

but if you are considering using them for a service you might be able to negotiate a big discount on those figures. (Once the car is in the workshop it is only a few minutes work)

Not too much hope but I'll definitely give it a go.

Wolverhampton charge £130 more than Telford for the service so I won't be taking in there, although the lady on the device desk immediately knew about the update.

Telford took all day to understand the problem once I'd booked in for a service, and I was promised a call back 3 times. Each time I had to chase up myself. Finally one of the people on the service desk spoke to a technician and advised they charge £130 For the update.

I rarely pass a Tesla charger unless I'm heading south, so unless it's done for free or reasonably cheap this isn't a logical investment.

I think that if you explain to them that you'll take it elsewhere for a service then you might get some leverage. (Of course, it helps if there is somewhere else you can take it)

They told me they would just charge for labour so cost would depend how long it took them (estimate was 'up to an hour'). In the end it took half an hour.

I might be doing them a disservice but my suspicion is that half an hour is their minimum time period.

I don't doubt it, but it's the way things are and I just wanted it done.
