Yes, I tried pretty much everything but the heat pump isn’t even turning on (I tried setting it to the highest and lowest setting etc.. but nothing happens - you can hear that there is no noise coming from the front of the car). There were some people with older cars that had issues where the AC...

No, actually not. For ACC I have the one where they switched from +5 kmh steps to +1kmh. It definitely now does not slow down anymore before turns as it used to before. Is this the most recent one? I hate how in-transparent this hole update thing is.

The weird thing is that I have most of these updates but my infotainment is still on R46. E.g. I have the updated LKA and also the updated ACC but I don't know what version the HVAC has - I know that there is an update as well that does something to the controlling of the heatpump (I think it's...

No, because they refuse to do it. I told them that there are known issues with old software but instead they are telling me MG told them to check all the cables and pipes and the car can't diagnose it self (which is wrong because there error codes for over/under voltage and short to GND). If...

UPDATE: Just had a call with the dealer regarding my my issue and what they did to fix it: According to them they followed the MG procedure and then did a "visual inspection" and read the DTC errors. That's it. They want to give me a new appointment in mid/end of January where they "control the...

I now have a 12V heat blower from China to at least get some warmth into the car and prevent the windows from fogging up. However, I’ve almost completely lost trust in the service centre. Because of that, I bought the VNCI tool for the MG and, if they are unable to fix the issue, I’m going to...

Sorry to hear that. I mostly had issue with the service of the dealer e.g mechanics that can’t tell the difference between left and right or they told me I lost warranty on my TMPS due to me changing the tyres.

The dealers themselves often have no idea- I don’t have a XPower but with others parts I have similar experience (MG just isn’t very picky with who they choose as a service provider). 🤷🏻‍♂️

Not sure whether this is already known but maybe it helps someone

I have somewhat of a theory on what could possibly be the issue: ┌─────────────────────────────────────────┐ │ Symptom (What You Experience) │ → Heating system not working...

Ripping the software is so easy (as it’s really just an Android phone) - I even know a case were someone was able to extract parts of the software. If a normal user can do it, other companies can do it too. But nobody would want this software anyway.. 😂 I just think MG isn’t very picky with...

The thing is most technicians are coming from gas cars where everything is more analog so you can see very clearly where most issues are coming from which doesn't apply to software. I am pretty sure that in case of a hardware error we would see something like a DTC indicating that (like drop in...

Quick Update: Had my service today and they weren't able to figure it out, so they opened a ticket with MG. I assume they just followed the normal procedure: 1. Disconnect 12V Battery, 2. Flash software, 3. Check harness and connections, and 4. If nothing does the trick, call MG. They told me...

Hope it is worth all the work.

https://github.com/SAIC-iSmart-API/saic-home-assistant-addon You add it as an add on and then can find the car as an Mqtt device

I would recommend switching to the python gateway (more stable). I had a similar issue but with the gateway (authentication failed). No clue what the issue was (I switched to the integration with the same account credentials with no issues). It just fixed it self after 3 days 🤷🏻‍♂️🤷🏻‍♂️

Are you using the python gateway with Mqtt?

Maybe this is helpful for your case (to understand what MG is actually doing in their service centers and what they do if they encounter certain errors/behavior : http://www.siteguru.co.uk/MG4/Manuals/ (Seems to be mostly official stuff from SAIC/MG regarding repair and other stuff for service...

Just checked my error log via OBD and I actually had some errors. So I cleared them, let the car sit for a couple hours and took it for a drive and also messed with some settings in the AC menu but nothing showed up. I really believe it’s an issue with the software - therefore the hardware works...

I just checked all the fuses in the front box but with no success (would have been to easy anyway). So I now ordered an OBD dongle to check if there are any error codes (should arrive tomorrow). My service appointment is on the 18th of December. Out of sarcasm I renamed my car from microwave to...

For context: I have a heat pump 2023/09 model (Luxury) and I tried everything possible that I was able to think of (reset, reset to factory settings etc..) - When calling the dealer I asked wether it's a good idea to unplug the 12V battery and they said it's not a good idea because MGs seem to...

Any updates? My AC just broke as well - only blows cold air. Sensors are reading correct values and the heat pump isn't running (you can clearly tell as you can't hear the usual sounds). MG is really giving their best that this is the first and last MG for me. I have a service appointment for in...

Anyone asked the dealer for the cost of replacing the part?

I had the light come on twice today (first time ever). Only flashed once but everything was still working. Second time was today in the parking lot after driving home - again just came on for a second and disappeared again. No clue what the issue is.
