Hi guys

 
my older brother has recently bought a Skoda Octavia 2019 1.6tdi DSG Automatic from someone private. 
Everytime you unlock the car on the speedometer it says check starter service and it beeps. Same thing after switching car off he gets same message and beeps. 
I’ve checked using vcds and no fault codes appear. 
I’ve inspected the glove box and noticed a red wire in between a red 7.5 fuse. Not sure if that is the culprit. Any ideas?

 

That looks dodgy.  As standard there are no wires like that from the internal fuse box, so it must be a third party accessory.

Where does it go?

I get an odd idea it hasnt left the factory with a strange red cable forced into a fuse holder.

Well I inspected that red wire and it’s connected to a black wire with tape around it and as far as I can follow the black wire it goes above somewhere on top of that section at the top of the glove apartment. I didn’t want to remove that wire in case that causes any issues with the bcm unit. 

My question is what is that 7.5 fuse used for on the car?

So I’ve inspected and followed the red wire and I’ve noticed the glovebox light switch has a black wire connecting to the red and that’s what is connected to the 7.5 fuse. 

Is it the same fuse position as the one listed for the glove box light? If not, locate the correct fuse location for the glove box light and remove the fuse. If the light stays lit after removing the fuse the extra red wire must be for something else.

According to Skoda fuse box diagram it’s connected to fuse 34 

I’ve also noticed car speedometer also flashes up saying Electronic Stability Control 

If i pull that fuse out I hope that wont blow the bcm unit as i had that issue on my own Skoda Octavia with interior lights and radio/speedometer going dim. 

Try asking the previous owner about it.

I’ve managed to remove that red wire. Glovebox and all other interior lights were still working so just put the fuse back in and cleared all codes on vcds. Check starter service/beeps and ESC message no longer flash on the speedometer. 

A very odd and dodgy bit of additional wiring there.

Even my old Landy with wiring for 'aftermarket accessories' at least went to a block somewhere in the birds nest.... I mean wiring loom and not a wire forced into a fuse holder.

 

Hopefully it'll stay running fine for you.

Do you know the purpose of the red wire?

Have you removed it completely from the car,or just disconnected it from making contact with the fuse?

That wire squeezed into the fusebox is a remarkably inept bodge of a modification to inflict on a 2019 vehicle, IMO. 🤨

My older brother said he hasn’t had any further issues on the car since I removed the red wire and put the fuse back in as normal. 
Strange thing is that the red wire as showing in the picture above was also joined to the glovebox interior lights switch wire. I removed it completely from the switch so the fuse. 
that stopped the car from showing and beeping the check starter service message and ESC message.
