Won't start after light accident

Hi all!
Bought the car ( W213, 2017, 9K on the clock) from the auction with light front damage, steering wheel, knee, left curtains deployed. Car not starting.
battery flat but when we connect the jump lead the ignition turn ON but nothing else....
can you give any tip what it can be, pyrofuse, srs reset or need propa computer work???
the guy next garage had the same problem, he call some tech with some machine who found the problem and start the engine even with deployed airbags but I won't pay £500 by now if I at list try my own best.
thanks

I'm no expert but it's easy to imagine that cars are designed not to start if the airbags have deployed.Just a guess on my part.

you are 100% right but there is the way how to fix it, I looking for that way!)

Well, I don't like the sound of this.

So, if God forbid I had an accident, airbags deployed, and I switch off the car to get out and inspect the situation (i.e. other car involved, passengers, damage, whatever) then need to start the car and move it to a safer position or on to a recovery truck - this wont be possible? The car cannot be started again?

Doesn't seem too clever to me.

I appreciate that the safety of the car would be compromised without airbags so by all means it could go in to a "limp/recovery" state, restricting engine rpm and overall speed, but it should still start and allow you to maneuver - that's my opinion anyway.

I think you're asking for a mechanics solution to a situation that is likely out of the vast majority of our knowledge. The picture you showed clearly shows the car was in an accident. There's no way for any of us to know how severe it was to the myriad systems in your car. Only a qualified Mercedes mechanic can evaluate what needs to be fixed in order to make the car run and road worthy. This is like going on a forum, and telling regular people you have a pain in the lower left side of your abdomen and asking what is wrong with you and how to make the pain go away. A doctor would need to see you and then make a diagnosis.

This. That being said, depending on the severity of the accident, there may be a battery disconnect. If you're still seeing some power to the car, it might not be the case. I'm not sure that airbag deployment shuts off the ability to start the engine, for a number of reasons. Would definitely recommend getting someone to hook it up to an SDS and see what codes it's throwing.

Here's my guess: The W213, like its predecessors, has two batteries. You're probably able to see instrument cluster and some limited information due to the auxiliary battery being connected. The car may have disconnected the primary in the accident due to perceived severity. So, you're getting some activity, but unable to start. That's my thought on it.

thanks. As I mention in above message the main battery was dead completely cos car was parked somewhere while insurance deal with the incident case ( found conformation) so systems eat all power, when we connect the battery pack the car got alive so probably nothing happen with the pyrofuse or prefuse it also called.

I wonder if all batteries go dead (primary and aux) if something needs to be done by a dealer or road-side. I haven't ever heard of that, but maybe that's part of the complication. I mean, it's a car, it should start if there's enough starting power. When you connected the starter pack, I wonder if the car might not like its power delivery profile? Maybe too much power from the pack was draining to the main and aux batteries?

Mercedes have alive systems all the time so they use battery power all the way. The car I bought was parked for long so battery dead. AUX only for stop/start and other small stuff.
there are other problems... looking for which one. Will see on Monday what the Star say and call for stealer for their advice. I heard Merc dealer must connect Online with main MB database and reload the car or clear crash data in ECU then vehicle will start again. Madness )))

Most vehicles have an inertia, or fuel cut-off, switch. They are designed to turn off the fuel pump and prevent possible fire following a collision. Most can be reset. You should really have a qualified person check this out for you.

No disrespect, but testing it might take special tools. Tied to seat belt tightening, air bag deployment, fuel cut off. Good luck.

As with computers it isn't what you can do, it is knowing what/where to do it with the necessary tools. You will most likely require Xentry, Vedaimo and a few special purpose tools to do full repairs. Purely mechanical repairs are for last century vehicles.

Possible! I found the guy who are do computer jobs to Rang Rover dealer, he must know whats going on with these new, stupid technology. Desperate to talk but Im currently outside UK so it wait till Monday. Will keep update!))

man with Xentry computer came today, when we were talking Sunday night and I explained the problem he said thats he make the engine to be run, but didn't .
last night I put the new battery, original gone completely
he connected his computer to the car, Xentry found 36 ECU form 39 existing, it does not seen engine ecu, transmission ecu and fuel pump ecu! he said that he never saw this problem before. we connect the main plug charger on car to keep the voltage.... once or two times Xentry connect to all 39 systems but when we click on each there was message the " info unavailable".
he left without result and money.
the technician owner the workshop where my car parked and waiting for rest of jobs put his computer and connect to the car, we got the same thing, 36 from 39 ecu available... so something prevent the Star communicate with those 3 systems, if you don't have it you can't know what the things are faulty.
any idea?
thanks

You really need to turn this puppy over to a Mercedes service center. People here could guess till cows fly, but that won't likely get your car out of where it currently is.

Yes, we are most assuredly interested in the outcome, but you keep asking for ideas as though you think we can diagnose a car damaged in an accident. We simply can't. Western world or not, you need to invest in having a qualified Mercedes dealer to get it running.
