Battery Died, Jump Started the Car, Now Radio Wont Work
Also, is there a way to boost the w211 from somewhere other than the actual battery in the trunk? Was quite the struggle getting the trunk open to boost the car so it would be helpful to know in the future in case something like this happens again.
Thank you!




Maybe someone has a solution here, but you might be due visit to professional shop.
Wagons do have jumping prongs under the hood, but not sedans.
Beat me why as all W210 sedans do have jumping prongs.
Beware that electronic cars don't like voltage spikes what have to happen when you jump with cheap cables and/or don't make proper clamping.
