After a bit of advice please folks. Had my trailer on the back of my fl2 today for the first time since I've had the motor. All going well for the first 8 miles, then the indicator buzzers stopped working. Got to destination round the corner and only.one side of lights working. Anyhow, gets home, reversing motor into the drive and noticed the reversing sensors on a constant beep when miles away from objects. Worried now I've upset something on the car, I've only had it 2 weeks!!! Had the caravan on it last weekend with no problems at all??????

Please tell me this is something simple, like a fuse 😮😮😮😮

Sounds like you need to check your trailer plug wiring particularly the joint between wire and brass connector - they do come loose with usage - screwfix do replacement plugs for a few pounds
Failing that it could be loose connector in the car under left of the boot where toewbar socket joins with car loom
This might help

Many thanks, just been out to try it again but not.much difference. Could it be down to water in the electrics as it was throeing it down this morning when I was hooking up, using it etc.

Yeah could well be that - the plug comes apart very easily usually there is a screw at the base where the cable enters - unscrew that then gently prise the two halves of the plug casing part - there will be some sort of plastic lug holding them together - then you can see the electrical joints and brass pins - if its wet it should be obvious.
If not there then check out the socket as well AFAIK that will be held on with two small bolts and can be removed for inspection as well but I would think it is your trailer plug - do you store it outside when not in use? No Longer the owner of a 2013MY Fuji White GS

It is outside when not in use to be honest. I noticed it as soon as I unplugged the electrics and reversed the motor into the drive. I'm hoping the socket is wet due to the trailer plug and will dry out the car socket and everything will be back to normal - in an ideal world !!!!

You could try disconnecting your battery and let the can system reset it has worked on a few gremlins I have had on mine costs nothing and well worth a try. Understeer when you hit the wall with the front of the car.
Oversteer when you hit the wall with the back of the car.
Horsepower how fast you hit the wall.
Torque how far you take the wall with you.

Went out to it this morning to try it, still the same. Drove over to chester, parking up and it worked perfectly. Not sure what it.was but happy again. Thanks guys. 👍👍👍
