Hi All,

 

I have a pre-facelift 2010 1.2 Yeti and for several months now I have had a strange problem with the Traction Control system. If the car is stationary for a few minutes without me touching the brakes, throttle etc, there will be a 'ping' noise and the Traction Control Warning Light comes on (yellow car leaving s-shaped skidmarks, NOT the ESP OFF warning light). Turning off the ignition and turning it on again always clears this warning light but it is really annoying as I prefer to use the handbrake when waiting at traffic lights etc, but if I do so there is a chance the warning light will come up. The light never comes up if I keep my foot on the brake when stationary.

The local garage directed me to a Skoda main dealer, who found and fixed broken wires in the drivers door wiring loom (a known issue with these cars) and also installed a recommended firmware update, but the problem is still there and does not happen frequently enough for them to do any further troubleshooting on it. Both the main dealer and my local garage cannot find any persistent fault codes.

 

Based on the above I have two questions;

1) Any ideas what could be causing this?

2) Can anyone recommend a good-but-inexpensive OBD diagnostic kit so that when it happens I can plug it in and see what fault codes are active?

 

Thanks in advance for any useful advice.

Might it be that your battery is low?

I wouldn't have thought it to be a battery issue as otherwise the light would come up when I'm stationary and with my foot on the brake, which it doesn't.

Low battery levels causes all sorts of funny "problems". Take a resting voltage reading.

Checking with my trusty multimeter gives a battery voltage of 12.31v with the ignition off and one of my two dashcams plugged in. Is that good, bad or indifferent?

I have also purchased a well-reviewed plugin solar charger unit to help keep the battery topped up.

Any suggestions for a good-but-inexpensive OBD diagnostic kit?

That seems pretty good to me. I'd also check for something around 14.4v with the engine idling.

Was that measured in the morning after standing overnight?

 

The voltage measurement of 12.31v was after standing overnight. I will be using the car tomorrow so I will take more measurements then with the solar charger disconnected, and with the engine both running and before startup.

Voltage measurement with engine running and both dashcams connected = 14.15v

Which isn't what we asked for.
What we need is the resting voltage with nothing connected after atleast 3 hours.

You did not take a morning pre startup voltage with the solar charger connected did you?

Whatever way it was done its unlikely to be a true reading as the vehicle will have been woken up by unlocking/opening the door or bonnet to take the multi-meter reading.

 

But 12.3 volts under those circumstances indicates a healthy battery.

Which is a load and therefore will affect the reading,

I am having the same issue did you amange to resolve this?
