Vacuum System and Control System Fault

[Robert Gardner]

I got the following warnings: Vacuum System Fault, Power Limited Limiting Speed and Vehicle Control System Fault.

The car would move but when you put your foot on the brake the pedal was rock-solid and breaking very poor all the dealers I am trying to book in with are talking about a 3 week wait not good enough for such a serious fault

Would it not be quicker to call MG assist they can tow the car to the dealer as you can't continue to drive like that?

Have you already tried the simple stuff like a 12V reset?

I take it you're using your free MG assist\AA

 

[Robert Gardner]

AA MG Assist were great they came out and on their notes about the MGZSEV, they have a reported issue of a 5 am fuse that feeds the ABS Braking system blows so you don't ave assisted braking. They replaced the fuse and it is back to normal but they then refer you to the dealer, booked into the earliest appointment 27/3 not the nearest Dealer but other Dealers closer were not available until mid April.

 

[N2STY]

That's ok then I was thinking you were stranded

I have to say this web site is amazing thank you all for your suggestions also I only do a out. 6000 miles a year and the variations in service costs are vast, the Dealer I have been going to now charges £350 for the Low mileage service and £550 for the normal service the new dealer I am seeing on the 27/3/23 only charges £110 plus vat for the low mileage service
