Control arm snapped- can't steer
New to this and first time posting. Please note when it comes to cars my knowledge is non-existent and don't have a automotive/ mechanical background.
Our car was involved in an accident where a moped driver drove into driver side wheel and the force of the moped hitting it somehow managed to snap a steering arm(?). The steering is completely disengaged and it had to be towed to a garage and we of course had to go through insurance. The garage gotten back to insurance and says it will cost over £6k to fix it and possibly more if there is more damage once they strip the car. So insurance and garage decided it's total loss but still being reviewed. Of course the garage does not want to give us any information regards to repairs.
Looking at the picture it doesn't look like much (my partner was driving it), bumper/ headlamp scratched. Looking at the parts list provided by the garage it mentions: lower control arm, tension rod, shock absorber, steering knuckle, wheel hub and list goes on but I listed ones I believe needed for it to be get to a state where its drivable.
The car is 2011 E350 estate in pretty mint condition when we brought it about a month ago. I'm kind of sus about the quote from the garage because I guess once its written off they can buy it for cheap and fix and sell... obviously I'm just speculating

Anyone had any similar repairs done, have any idea what the issue would be?
We would like to buy the car back...do you think something like this is worth getting repaired ourselves after the car is written off?
I know it's hard for anyone to tell without actually inspecting.
I've looked at some YouTube videos and it seems repairing control arm and steering seem like a simple job for a mechanic?
Any advise is welcome

Thank you,
I cold see a ball joint or steering linkage end maybe.. but A-arm & Knuckle?
HOw fast was the moped going and how far did its driver fly thru air?




If possible I would try getting a 2nd opinion. From the picture, this side of the car looks great.. It would be a real shame to totaled.
NOTE: In Canada and USA it is possible to buy back your totaled car from the insurance company. You have to do the math if the cost of buying it back plus repairs it is worth your time and effort to deal with the repairs on your own. That way you keep your car with perhaps a minor loss (call it investment to keep your car instead of getting a newer one). Done it once, and I kept my car (Toyota) with a minor disbursement. Numbers: Totaled value ($4500) - Deductible ($500) - BuyBack ($500) - Repairs ($4300) = -$800. Basically, I paid $800 to get my car repaired. I never (still) understood why the insurance totaled.
. I drove it another 6 years after that for a total of 18 years ownership and I only towed it once because of this accident (black ice)

the problem you're facing is, if you want a 2nd opinion, you're going to have to get the car towed to another shop, AND a non-roller is a real pain for a shop. just to get it on and off their lift for inspection.

I sold the car w/o any issues or markings in the title. At least that was my experience, and I will consider it again based on the available information and future plans for the car.
I think there is a subtle difference between a "totaled car" (probably also means salvage) and a "total loss car", and anyone pursuing this path should definitely find out beforehand how will the title reflect the "action taken". I perhaps missed the "totaled" and "total loss" differences, but I definitely meant a vehicle w/o issues that can be put back on the road w/o baggage of any kind.

Thank you,
for me it sounds like the repair shop wants to get your car totaled and then buy it back cheap for cheap fixes and have a nice clean car to drive.
You can buy a whole set of front suspension parts excluding the air struts if you have Airmatic for about $1000 and this includes both sides.
If the moped hit so hard that it snapped the steering link rod then it is probably the only damage in the suspension as it had to hit the front wheel in outer rim on the steering rod side.
My recommendation is to have the steering rod replaced and do front alignment and then see if there are any issues with suspension when driving the car.
Personslly I don’t think a moped driver would be walking away from a hit that would break any other suspension members. Speed would have to be so fast for a vehicle probably weighing only 250 lbs. or less.
Tow the car to another shop and ask them to replace the broken steering rod and do alignment. Drive it and see how it handles. Then ask what the cosmetic repairs cost.
Looking at the picture it is a Wagon. I would not want to let it go.
Then you can also ask the insurance what do they pay without totaling it and then fix it yourself.
A moped hit does not sound right for me to total this car.
Update-
Insurance ended up writing off the car (total loss), we brought it back and repaired it by a trusted mechanic.
It turned out the control arm was snapped on the driver side and headlight frame(?) (sorry I forgot the exact name for it) got bent on impact and had to fix other small bits. All fixed, cost us less than £1.5k with MB parts and inc labour, compared to what the insurance approved garage quoted, £6.5k+. The car drives fine and I say fine because both myself and my partner noticed a slight difference when we drove it at a high speed (over 100mph+ on a motorway, of course there’s no reason to be doing that speed). The car felt slightly unstable, kind of scary at that speed since having it back. May be because it’s been some time since we both driven it but we both remember it feeling more grounded at high speed compared to what it is now, not sure why. Normal driving around feels absolutely fine.
Glad to have her back, forgot how fun she was to drive and what a beast she really is. It’s a pity that it will forever have Cat N attached to it but not many on the market with the condition we brought it in.




When you said "slightly unstable", you mean no vibration but "too nimble for its own good", i.e. minor motion of the steering wheel got you an unexpected response of the car, correct?
I assume a 4-wheel alignment was done, and it is within the specs. Not certain, if during the alignment any frame misalignment can be noted. Others more knowledgeable members can probably help diagnose the "instability" you have noticed. In any case, avoid those speeds until something is figured out.

Forgot to ask. If you have the "approved garage estimate" you can review the parts list and description of the work to see if something subtle is mentioned that could lead to the behavior you are experiencing. Sometimes we dismiss something saying " nooo, that is not needed", but it might be.

I’m terrible at describing but will do my best. So before the accident when we drove it and going at high speed it was like an arrow that was shooting straight (literally the best way to describe it) and now it feels like it pulls to the left slightly and we didn’t notice that before at all. When the wheel alignment was done they noted that it was slightly out of line but nothing major that they felt the need to redo it.
We will definitely have it looked at again and definitely will be avoiding high speeds 😅




WIS/EPC has a set of documents with measurement value to confirm ( after an accident ) if the chassis is out of spec.

Take photo of the alignment result, share with us. If they rely simply from alignment machine database, it is not good enough.
MB has so many models variation, only WIS information is reliable if we want the ultimate accuracy.
Example below are MB specified values and allowable out of spec limits for my chassis.
Due to my rear 255/40 Michelin, 1 side is bad due to excessive Road Force variation and I bought a new tire while claiming for it..... I had the opportunity to see what a few millimeters
of taller tire ( 1 new tire ) can effect alignment value at the rear. That is the reason I did my 10th alignment and later 11th alignment when the claimed tire got replaced by Michelin Indonesia.
See the 9th alignment REAR CAMBER RIGHT SIDE and compare it to 10th alignment.
At 9th alignment, all 4 tires are under 1,000KM old.
At 10th alignment , rear right tire is 1,700KM old while the left one is near 7,000KM old or XX millimeters less tall.
Now see 11th alignment, where the age difference between both rear tire is only 2,400KM at best.
See how the RIGHT REAR CAMBER at 9th alignment and 11th alignment is nearly restored back from 41 minute to 42 minute,
where when at 10th alignment it was 47 minutes. Minute tire thickness difference between right and left rear tire create those differences at 10th alignment of approx 6 minutes.
Bottom line : This is how sensitive a suspension system is to changes.
