I've jaguar S type 1999 car and the battery is going dead. I found the problem, the low beam and brake lamps blink every 30 minutes. Every doors, bonnet and boot close correctly. How I resolve this problem? I give my car at dealership and they couldn't find the problem.

 

Probably a power drain - read the threads about that & quiescent current and follow the advice.

 

Hi Osura
I found this link that explains what could to be your problem.Post 3 "xjrguy" discusses the symptoms and remedy. The rest of the discussion goes onto the later 2003 model and may not be relevant to your car.

This is a pdf for the Jaguar Technicl Bulletin. http://jagrepair.com/images/TSB/TSB2...nt%20Drain.pdf

Post 3 in this link is where it came from. https://www.jaguarforums.com/forum/s...y-drain-64937/

 

Thanks for your help
