I was wondering if someone could advise me on an issue with our Skoda Superb. I unlocked the car remotely, started engine etc and took off handbrake and the car resisted moving forward. If I floored the accelerator the car could lurch forward. I just couldn't get the car to go. I had several attempts and then somehow got it going. The next time I started the car the same thing happened but it seemed locking and unlocking car using door switch sorted it. The safelock warning was on display the whole time. Has anyone else experienced this? What was I doing wrong? We have had the car 6 years and this has never happened before. Thank you
