Hi guys, Ahh. The wonders of Jag ownership. Came on board about six months ago. Constant minor items being sorted since. The latest, Battery drains whilst car parked. RAC. out twice. Now bought emergency starter. Anyone have idea what could be causing drain? Replies will certainly be appreciated. luv all. Tony.

Do you have the x308 (steel version) or the x350 (aluminium version)?

First place to check is the little flap in the ignition switch is closing when the key is removed.

Next and most common, is the “alarm chirp sounder”. This has a rechargeable battery that leaks overtime and shorts out causing the drain.

Welcome to the wonderful and sometimes frustrating world of Jaguar ownership and maintenance. They are somewhat renowned for battery discharge. I personally (as many others on this forum have) invested in a CTEK MS 07 battery charger and restorer. I use it very regularly , at least once per month and always for at least 24 hours. It keeps the battery well maintained and greatly reduced the number of fault codes and starting/running problems that can arise from a lower charged battery.

Best Wishes and Regards, John

Hi John and thanks for your recommendation re. CTEK MS 07. Have been searching on the net. Unable to find an "MS 07" Plenty of other Ctek models shown. Suspect updated since you got yours. Would you kindly have a look and let me know which model is equivalent. Ta. Tony.
