I have a w202 c180 1998. One day when I go to start it(it was fine the previous day) when I try to start it the key turns to position 2 which usually would light up all the lights on the dash but now they all go off really quickly and when I go to start it, it makes a click and that’s about it. I have really recently 2/3 weeks ago had a problem with the ESL (key would just not turn at all) and the mechanic just swapped it with an ESL emulator so I’m wondering if it could be that. I have attached a video of how it looks rn with it connected to another car since for some reason it just fully died after what happened initially for some reason.
