Hi. I have an S class W221 and needed to transport it on a trailer to another country. The car was working perfectly. I loaded it onto the transporter, turned the engine off, got out and locked the car. 5 minutes later, we needed to move it forward a touch on the transport vehicle but the car does not start. All electrics are working and we can turn off the electric brake and put it into neutral. I found that the "Tow away protection" had been left on and I was able to switch it off but still no luck starting the car. Any ideas? Thanks.
