Morning all,
I only use my W140 once a month for a 300 mile round trip to my work office and when I moved at the weekend to give it a wash before this months journey the battery was completely flat. I tried a power pack and also tried jumping from a spare battery but neither worked so I put the battery on charge.
The battery was new in 2023 so I dont expect it to be the battery but did notice that when recharging it never reached "full". After 3 or 4 hours I gave it a go and it started OK but with the SRS light on.
I went to move the car yesterday to go for fuel as I intended to use the car tomorrow for the work journey but the battery was flat again, luckily I have a spare identical battery so I swapped them over and it started up but again the SRS light is and and doesnt go away even after 5 minutes of running.
I suspect a parasitic drain on the battery from somewhere causing the flat battery, any thoughts on this and the SRS light please?
thank you
