Smart 453EQ - DCDC Repair A4533404500 292A05698R P0852F1 

Hello. I live in Norway, and there are hundreds of 453 eq. These problems you mention are not known to the Mercedes dealer. Strange as they have a common computer system in Norway, and can look up faults on car models. An acquaintance of mine works for mercedes and he said the 453 eq was a reliable car with few faults. In Norway, the car has a 5-year warranty, and 8 years on the battery. My car is now out of warranty (5 years last week), driven 67,000 km without a single fault. Have spoken to at least 10 people who have a similar car with a mileage of 30-90,000 km. No faults on the cars. Have we in Norway got better quality since we have a 5-8 year guarantee?

Hello I live in London. I have a smart 453 eq 2022.Recently I had an accident.Everything has been fixed even crash sensor has been replaced but they car can be charged. Both batteries are flat I used jump battery. Dash come on shows don’t tow the car and goes off. Can you please advise me what should I do? Thank you

Koliko ih cesto dobijate s ovim defektom kad mozete ponuditi live training lol? Jesu Twingaci u slicnom riziku?

This makes me regret buying a smart car. It’s a 2018 and been good so far with 25000km. If this goes there are no 3rd party companies to do this work so I will have to cut my losses and send it to scrap. Not worth investing in a disposable car. Probably going back to gas car if I end up with an expensive repair like this. A good used gas car for the cost of this repair and a few thousand extra. Disappointing seeing this. If it was externally mounted form the motor this would be adaptable as I could do it myself
