Re: i3 Accident Collision :(

Thu May 18, 2017 9:23 pm

One other thing to consider...and I'm not positive on the i3 but true on others, that tensioning action stretches the seatbelt webbing, and they should also be replaced after being triggered or they won't provide the same protection should they be needed in another accident. Some systems just snug them up with a motor, some use a pyrotechnic charge. Not really sure which the i3 uses. If it's pyrotechnic, for maximum safety, the seat belts may need to be replaced. If the crash is significant, just your weight and inertia can stretch them, and they should be replaced. They may look fine, but won't perform properly.

Seatbelt is in a locked stretched position , very far stretched not sure how big the previous owner was lol, I'm telling you I'm a big guy I weigh 115Kg six foot four tall and this seatbelt was like about 20cm loose around my chest when plugged in HAHAH. Open" ed the seatbelt to attempt some sort of repair to unlock the locking mechanism that locks the belt in a collision , had to basically pull the whole belt apart and it works on pyrotechnics too as the 12v battery lead does. It forces about 15 ball bearings into a carriage that lock the seatbelt. Pulled apart the belt removed all the bearings but the belt does not function like before (engages only sometimes) I think if you did it with time and concentration and a lot of tools you would be able to "maybe" manage a pull apart and , put back together, but you would need to shear off bolts that close up the whole seatbelt system then maybe replace them with nut and threads , also the plastic clips would need to be either drilled or broken apart and somehow screwed or glued back together , the reason I attempted to do a repair here in Australia a seatbelt is about $700($500USD) so it was worth seeing the difficulty involved and if it was possible. Personally I wont gamble my life with a seatbelt, so I'm going to be getting one from the states , paid for it $85US about $110 Australian dollars.

I have opened the battery lead it works on a charge system too (pyrotechnics) it is a simple system, that can be re-engaged by bending the lead back to make contact with where it separated from , used some pliers (very easy fix) , now will maybe have to place a resistor there to bypass the system from saying "SRS faulty". I think I'm going to have to take out the HV battery because the dash still comes up with a error saying HV system not activated , so maybe there is another safety mechanism at the battery not sure hopefully the previous poster who has the diagnostic diagrams is able to shed light, or anyone else for that matter.

How do you upload photos ?

Here is a photo of the positive lead disconnecting by the safety pyrotechnics system after collision, this disconnects the High Voltage battery https://goo.gl/photos/oRqckJQgh7Q1FRBx6


This is it pushed back in to re-engage the High Voltage battery, notice how the ball head is pushed into place (engaging the HV battery)
First disconnect the orange clip near the bottle for the HV battery

Here is the cover removed from the Positive Terminal to access the repair, notice I used a drill to remove the pins

Does the HV battery have its own independent safety disconnection in case of collision ?

Hi guys cleared all collision errors from the computer , but still have a F15 terminal temperature error that Is stopping the car from starting.

Does anyone know what sensor is responsible for this? or if this is something else? I'm totally lost with it

Normally, if someone has a significant accident they have the repairs via the insurance company. Don't you have insurance?

The car has been sitting around for half a year. Even if the BMW spares are delayed, the repairs would be done a lot sooner, and correctly repaired rather than altering the connections etc...

Hope you get it sorted and back on the road soon.

I don't have a picture of the error code I had someone come out and scan it charged me $100 cleared the airbag errors but , wasn't able to remove the issue of the battery terminal temperature error, he's explanation was to replace the positive battery terminal which was replaced with another BMW terminal (although not for the i3) still has the sensor for the pyrofuse which plugs straight into the the i3 as well. Unsure if it is that causing it, I called BMW today they said that the information for the the battery however is on the negative terminal which was not at all damaged in the rear collision which I only replaced the quarter panel and bumper cover :( I will post some photos , I'm thinking I'm just going to buy the Rheingold software and do it myself ! grrrr

There is two plugs going into the B+ positive terminal, one sets of the Pyrusfuse to disconnect in case of collision, the other Im unsure of and the technician pointed to that being the issue, however I am not sure if he is completely right, the scanner he had said "Terminal temperature not attainable" he reckons that is the plug responsible for it, however upon talking to BMW Technicians they said the negative terminal reads information about the battery. So I need to know what this little plug is if anyone knows as it is $1200 new from BMW , nobody has one wrecking as most cars are involved in collisions they wreck and usually have a damaged terminal "like mine". The negative terminal is available on Ebay for about $200 but their is no use buying either one without knowing which one is at fault , if at fault. And BMW wants me to tow the car to them, but with a damaged terminal arent willing to work on it , as It is "hazardous" to their workshop... :evil: :evil: :evil: :evil: :evil:

FWIW, when that fuseable link is blown, it does not disconnect all of the battery output...some things are still enabled like the BMW emergency cellular connection, and probably a few other things (like the hazard lights?). I do not know what circuits remain on, but there are some.
