MG4 Systems Unavailable

[edwardbahaw]

I am the proud owner of an MG4 in the small twin island nation of the Caribbean - Trinidad and Tobago.

I love the car but it has developed an unknown problem which has resulted in the following systems being unavailable:

• adaptive cruise control (acc) system
• lane keep assist
• forward collision system
• auto emergency braking system

Do you have any ideas about what can cause this?

I've had that in the UK when the windscreen camera (the triangle area behind the rear view mirror) became blocked due to frosting of the windscreen. Clearing that area and then driving cleared the errors. However I can't see frosting being an issue in T&T ... is that area perhaps blocked by condensation between the housing and the windscreen?

Have you inadvertently turned on towing mode? Its at the very bottom ( hidden , you have to slide up ) of the MG pilot screen.

Might also be worth trying a disconnect of the 12V battery - take the negative off for about 30 seconds then reconnect. To get rid of the warnings after this you will need to drive the car for a few miles.

Mine does this too. It also displays “Intelligent drive assist sensor failure”. On mine the problem goes away if you blast the aircon at the screen for 10 minutes or so. Have you tried that to see if it helps?

I had the front camera in the windscreen replaced but unfortunately the problem remains. I’m awaiting a call back from the dealership for further troubleshooting.

That would allude to a condensation issue as per my earlier reply.

There’s no sign of condensation in the camera as for me it only happens when the car gets hot, and then stops when the aircon cools the car down again.

Ah, so by "aircon" you're meaning you're blasting cool air not hot air? (Aircon doesn't denote a temperature, merely that the air is "conditioned", i.e. has moisture removed from it). In that case there's likely a fault in your case whereby a component/solder joint in that camera assembly is affected by higher temperatures.
