Hi, 

 

I have 2014 Skoda octavia diesel 1.6 which has almost 92,000 miles. Recently i started to get the following error messages: 

 

1. Gearbox Fault

2. Error stabilisation control

3. Error tyre pressure monitoring system. 
 

If I leave the car on ignition, all of these errors clear after 5-10 minutes. I’ve noticed that before these errors clear the coil light on the dash board go on for a second or two. Once cleared I can start the car with no issues. Yesterday the engine management light stayed on even when all errors cleared. 
 

I ran a diagnostic using OBD 11 and here is the details:

I took the car to Skoda and they were not able to get anything when they ran diagnostic on the car. 
 

any help on this is much appreciated. 

 

 

If you have not already done so fully and properly check the state of charge (and if possible state of health) of the battery, I wouldn't assume that the Skoda garage has, unless they proved it.

 

Have you checked that the battery terminal post clamps are secure (don't twist) and main earth connection is good?

 

Start with the basics, and in this case easy clean-hands stuff.  Put the battery on an appropriate battery charger maintainer (lower amps for longer is my preference) checking the car's Owner's Manual and consulting the manual for the charger for correct way with both (and slowest charge rate for my preference).

 

Don't just think your battery is fine without doing proper checks.  The computers run on 5v which gets a bit too thin when the battery is well below snuff (as you see I'm not technical).

 

As you had all the warnings on the car it's unlikely to be your OBDEleven at error or the car's port socket or wiring.

 

You may have more than one problem happening at the same time or one issue (like low battery) causing, or a contributing cause, to one/some/all other problems.

 

Failing that it looks like you might have intermittent connections/wires/computers/programs problem(s) with the electrics/electronics or their parts otherwise the Skoda diagnostics (depending on what it was, or was done) would have picked up on it.

 

Whenever you having (starting or) electrical problems having a fully charged battery will not hinder things but can help or even cure somethings but having a battery that is too low in charge can hinder or even stop diagnosis and/or repairs.  It's so easy to charge the battery to full and if it doesn't need much it won't take long to find that out and whilst the charger is doing its work you can be doing anything, in warmth and comfort, more rewarding and pleasurable than working on a car.  Leaving a charger maintainer on overnight and it's working while your sleeping, difficult to get easier car work than that.

 

Good luck let us know how you get on. 

 

Hi, what seemed to be the problem and respectfully the solution to it?
