Hello everyone,  this is my first Skoda and my first post.  Thank you for this forum, I've found so much great advice on it already and it allowed me to narrow things down.

 

We just got an 2017 facelift Octavia Mk3 1.6 diesal estate.   And love it.

 

The start stop system was working until I attached the dashcam from our previous car.

 

I've tried hard wiring to different fuses and using the 12v plug.

 

When the dashcam is plugged in we get the power consumption too high warning.  This disappears if I pull the 12v plug.  I have to pull the piggyback fuse as well, not just disconnected from the camera.

 

The dashcam is the type that attaches to the rear view mirror, which I like because it is discrete.  Previous car was broken into to steal a visible £90 tom-tom, probably worth about £10.  So I'm a bit worried about leaving a clearly visible dascam.

 

So how can I fix this?

Some better hardwire connector or new dashcam?

 

Might be a problem with the Dashcam itself. Which fuse position did you hardware the cam into? I personally used the fuse position for 12 volt socket and didn't have any problems with the stop start except when I drive off for the first few minutes when demand is a bit higher. 

Thanks for your suggestion.

If I just wire in the hard wire cable and don't plug it into the dashcam it still causes the problem, so if there is a  problem with the dashcam that won't show until I sort the cable issue.

 

I can't use the fuse for the 12v socket as that is permanently live and would drain the battery.  I tried 3 fuse positions and currently have it piggybacked on a headlight.

Regarding my set up, forgot to mention that I also have a parking mode in the Dashcam and it is connected to the rear windscreen wiper fuse position as a switched power output as well. The hardwire kit has a voltage cut out as well to prevent draining the battery too low. 

 

Back to your problem. It does sound like the Dashcam itself isn't agreeing with the vehicle electrics. Have you tried a different hardware kit or if not, a different Dashcam might be the solution. What model of camera are you using? Does it have any firmware updates available for it? Might be worth searching the Internet to see if anyone else has run into similar problems with the same model. 

This is the dashcam.

 

I have not tried a different one, note the problem persists if only the hardwired cable is attached, I pulled the USB end out of the dashcam and the still has the problem.

If you have the problem with only the hard wire kit in, the problem must lie there, as your dash cam isn't connected.

 

Do you have a clean/stable 12v coming out of it, plug end?

Can you see any damage on the cable?

 

Can you show a photo of your installation to the fuse box?

The hardwired cable includes a 12V to 5V converter for the USB cable to the dashcam, this converter will still be consuming power even when the dashcam is unplugged.

Hello Niccolo, welcome to the forum. Be aware that any unexpected current draw while vehicle is locked can cause other onboard systems to not fully shut down (go to sleep mode) This can cause a significantly larger current draw than the dashcam alone and will cause issues with the battery charge state.

As said above - welcome!

 

just a thought, presumably the dashcam came with a plug to fit the car’s 12v socket, have you tried using this and not the hardwire kit?  (Apologies if I’ve misunderstood your posts and have done this)

Thank you for all the responses.

 

I've tried it with the 12v socket plug and pulling out the piggyback from the fuse box, the problem remains.  I have not tried the 12v plug with the other end pulled out of the dashcam.

I'll send photos of the setup.

Will search online for people with same problem with this dashcam, will also be looking for dashcam setups that are know good for this vehicle or just any stop start system.

A possible problem with this dashcam is it is 5V 2.5A so is drawing 12.5 watts of power?  Could this be too high a draw no matter how it is wired up or would a new hardwired kit first, such as the Power Magic Pro help?

I'd rather not be buying dashcams speculatively.  These are a bit pricy. 

I don't know if the power draw in your dashcam is a problem.
If it helps for recommendations, I've got a Viofo A129 Plus Duo with their own hardwire kit and haven't had problems with stop start.
I know that it isn't the discrete mirror option like that one you are using, but it if is of any consolation, it is a fairly small.

I thought I had a similar issue - I've got Thinkware front & rear cameras fitted and soon after their install I noticed that the car wasn't doing stop/start anywhere near as often as it did.

My cameras were installed by the seller, hardware/parking kit, etc.

Anyway - service came up on my car about 6 months later, ran the battery through the tester and there was a cell out. I'd seen no symptoms of that at all - car was starting on the first turn etc.

Had a new battery fitted and now the car stop/start as much as it did before the cameras were fitted.

The battery was the problem.  There's nothing wrong with it as far as I know but it seems to need to be fully charged or the dashcam caused the problem to come up.
