330D dreaded severed wire issue.

Post by Tourer_13 » 15 Jun 2018, 20:23

Apologies as I know this topic has been done to death. However, I cannot find any posts that say what wire to use to fix the 3 severed wires. Does each certain wire need to be a particular ampage? I'm struggling to find even online the same thickness and colour combinations. I've my connectors, crimping tool, spare fuses and am itching to unhook the battery and get cracking. Any help in regards to what can be used would be greatly appreciated.

If they're all lighting 7A is sufficient.

Blue and yellow is the central locking and one of them is the radio.
7A still suffice?

Just use 1.0mm in the closest colours, you will struggle to find the correct colour at a reasonable price, personally I would just pull a bit more through and join the original wires unless you need more than a couple of inches.

Also solder and heatshrink sleeve the joints as its far more reliable long term than crimp connectors and less bulky

What crimp connectors would you use if you had too? I've pink/red to hand. Will I need blue or are red suffice?

I would not recommend crimp connectors, if it rains to could corrode the contacts, i would do what Maxwell said solder them and heat shrink them as you will now it will not have any problems in the future

So I eventually got an auto electricain to fix it.
He wires a loom from down near the battery to just inside the lining from what I gathered anyway.
I have radio signal and one less code comes up on the reader so 2 things are fixed.
However I am now 120 sheets lighter and still the fob doesn't open the car.
Does having a faultless radio signal now rule out the diversity amp?
I had him try my fobs on a signal reader and niether gave a reading?
I struggle to understand how they start the car then as I'm not overly sufficient in auto electrical practices.
One fob is a new fob from Bmw Norwich purchased in 2016 to of which the invoice reads the key and the key blade seperate.
It does not however mention coding of the key?
Both keys start the car however.
Any help would be very much appreciated.
You .at just save me going bald :(
