So the Smart has thrown a wobbler. Waiting in a queue to fill it and rolled it down the hill in neutral instead of using the engine. Now giving time the ‘three line’ transmission error of doom and won’t start. Now waiting for the RAC to arrive as no amount of starting stopping or cycling up and down through the gear selector will bring it to life.
Also had to fill the 911 with Esso E10 95 Ron. Sorry car
Turns out it was the battery that was flat. Stupidly it will not let you turn the key to 0 in neutral so despite flicking the key as far as it would go it still has the accessory circuit on.
Normally the radio being on would give this away but also stupidly the radio stays on until you pull the key out in smart so I didn’t think anything of it. To be honest it shouldn’t have flattened the battery after 20 minutes but it looked to be an original so was probably on its way out after 5 years.
I paid the nice Mercedes assistance man 120 pound notes for a replacement as I didn’t fancy the earache of my wife flattening it again on the school run next week. I’m sure it was a few quid more than if I’d bought a Halfords replacement but not enough for me to faff around doing that and to sit there running the car for half an hour to ensure that it didn’t refuse to start the next time I switched it off.
Interestingly a young guy in a mint 1981 R107 SL (green with green carpets and tan leather - absolutely gorgeous) had done exactly the same thing. Fortunately my recovery guy got him going too.
