First and foremost I am sorry for your saga, it should not be like this. I was, like many a happy Skoda owner for some years, if you have a good one you are good to go but sadly if anything goes wrong Skoda and their dealerships are about as much use as a chocolate teapot.
This was the first reply I had from Skoda UK Customer Service;
I have done some checking regarding this vehicle and the issue is not one known to us on the software currently installed in the vehicle.
I have contacted the retailer, and they are going to contact us via Our systems so we can escalate it to the factory for investigation.
I am not able to give you a date on a solution, so I am not able to pacify the customer, but it will be processed as soon as we receive the details from XXXX Skoda and try to keep you updated on any progress.
Herein are three lies, I am personally aware of 2 IV's that had been reported to Skoda before mine, they already had the details from the dealership and Skoda Technical had been informed, lets be honest here if you are putting the same software, same parts on other vehicles in your range expecting a different outcome they are delusional.
My IV had 15 miles on the clock on delivery which in itself is no problem but given the warnings come on at start up and then every mile or so someone, somewhere should have noticed.
Skoda's fibbing and the dealership playing fast and loose with the law has convinced me to buy a Toyota
Good luck resolving your issues.
