My friend has just bought an XF diesel fitted a Jaguar towbar and 13 pin socket by the main dealer but his caravan brake lights won't work on his Bailey Pegasus, he's also tried another Pegasus with the same result. However when he coupled up to my 2010 Challenger my brake lights worked ok. The only difference is he has ATC and Tracker fitted and I don't. Jaguar assist have had 2 goes to fix it and are baffled as are Lowdham's and to complicate things even more we tried the Discovery 4 from assist which had 12N/12S sockets using my Y connector and the bailey lights worked ok. HELP

Could be the brake lights are all LED on the Pegasus and the vehicle is not sensing the caravan is hitched up ?

 

Seems strange that both pegs never worked so I would of thought its not a wiring problem with the caravan .

The jag XF has led brake lights, does your 2010 Challenger have led brake lights?

Hi Xtrailman, no my Challenger has a normal light cluster but it does have a high level LED brake light.

There was a post about someone with a BMW that was having issues, the cure for him was to convert the lights to LED.

The current the normal filament lamps was using, brought up a dashboard fault light, the ECU was detecting a out of range current alarm.

The solution was to convert two of the four lights to LED.

 

But your problem sounds different.

 

I have read that a land rover i think it was stated in the manual not to tow a trailer with LED lights, but didn't specify why.

 

All i can think of is to try the LED brake light on its own, by removing the two brake bulbs, and vise versa if possible. See if you get one to light up.

 

Did jag assist monitor the ECU brake element?

The car's in at Jaguar today and they've ordered 12N/12S leads to try in case all else fails.

If Jag can't sort it I would book it into a specialist towbar fitting garage. They fit towbars for a living - main dealers don't :)

It does point to the problem being LED lights as it works with your Challenger with filament bulbs and does not work with the Bailey .

 

If that is the case Jaguar wont find any problem as the wiring will be correct but it might mean the caravan brake lights will need a resistor wired in to the brake lighting to work .

 

As said a few car manufacturers are experiencing problems with the modern electronic CAN BUS systems in new cars and LED lights on caravans .

Hi folks, problem has been sorted by replacing the caravan's higher brake light 21 watt bulbs with 15 watt bulbs and leaving the lower 21 watt bulbs in place. Seems Bailey also have a problem with VW's as well, mainly Passats, looks to me as it's something to do with both cars having LED rear lights.

Good feedback Jim.

 

Sounds like the current drain was above allowed parameters?

My friend is a little angry as he spoke to a Bailey technical person last week but they never mentioned they'd had a similar problem with VW's or it could have saved a lot of hassle. I wouldn't care, we were thinking of taking 2 bulbs out ourselves but didn't think it would help. Also Jaguar have said they're going to see if they can upgrade their electronics as this will surely happen to someone else.
