Hi all,
I'm just looking for some advice on an issue i've started having with the Car since Lock-down (so a fair few weeks now).
I have a 2014 vRS with the small screen / MIB1 set-up. I've not long bought the car off a family member who had it from new (typically, no issues when he had it), to replace my 2012 Mk 2.5 vRS (hindsight is a wonderful thing).
Anyway, the problem is the screen locked up and stopped responding when driving home. I could originally get the screen to come on for about 10 seconds, then everything locks up and the system is un-responsive - no radio, Nav, Phone, vRS options, Car settings - nothing is work-able.
Pressing and holding the power button for 10 seconds reboots the system and lets me back in for another 10 seconds before it locks up. Eventually, i cant get in at all - i can see the screen comes on (I can see the back-light), but no splashscreen with the vRS logo or anything. I'm informed this is a fail-safe of the head-unit. if i pop the fuse out for the head-unit (and replace obviously), i then get the system on again, with the same 10-second problem.
I had the car in at Skoda this week for a major service and have paid the extra £100 for the diagnostics on the unit. Not bad value considering their head technician spent 4 hours looking at it while i waited!! Anyway, they couldn't fix it and want me to re-book the car in for further work. They did provide me with the following information:
The hardware is okay - it is a CAN-BUS issue. Apparently i am getting a high voltage showing on the circuit and they need to diagnose further where this high voltage is coming from? Either a module on the network, or a wiring fault? I'm no auto electrician, so not sure on what is involved in this.
I find it hard to believe it could be a wiring fault that just comes on so suddenly on a relatively new car? (I have a 16 year old Alfa Romeo in the garage at home, and ALL its electrics work fine!). I also have suspicions about the fault, as it come on the same time i jumped into the car with 2x Mobile phones in my pocket - 1 of which is my works mobile which was connected to the car for calls. The other is my new personal phone (Samsung S8) which did have its bluetooth turned on - never connected to the car before, but was connected to my old Skoda.
I had another little trial-and-error process in the driveway today - isolating the touchscreen by removing the fuse for it. I feel the touchscreen must be fine, as with the fuse out and the main headunit booted up - as soon as i make the touch screen live, the screen comes on and the system is already locked up at the menu screen.
So, any advice on this one? Skoda want me to book the car in at £70 an hour for a full day to fault find it, which is where i am up to at the moment.
I've only had the car a few months and its had a full timing belt kit, a major service, it's due brakes and tyres, and now the Infotainment doesn't work..... I find myself back on autotrader far too often
Many thanks.
