Got the car back
No specific leak was identified. I was suggested to either use an accumate or the master switch
It is freezing cold over here, so letting the car with no use to see how long the battery will last might not be representative, so I will try this later
Several times on the way back, I was under the impression of sticky brakes. I mean, like if the brakes were pressed at a traffic light, but the car, whilst in D would not move on iddle. A light press on the brake pedal, results in a 'clonk' and a leap forward, as if something went suddenly free, like sticking caliper
Is it a known problem?
Do you find the car seems to brake/slow up more than normal when you lift off the throttle as well? If so it might be a glitch with the brake light switch which confuses the computer and the ABS and ends up activating the brakes.
