Crimped connectors, even with adhesives/resins to try to give them some element of mechanical strength, will always be unreliable. Always.  I doubt anyone would dispute then, including the manufacturers.  Also, you need a crimp type very specific for the type of cable you are doing, and most bullet crimps or scotlok type are wholly unsuitable for multistrand cable, and virtually all loom cables in a car are going to be multistrand for a reason...

Crimps are fast though. Hence the bodgers love them. They rarely last, and cause no end of reliability niggles down the line...  ...the type that are a PITA to trace.


I prefer solder and heat shrink.  If I'm worried about mechanical strength, you can get heatshrink with a heat activated adhesive on, but I tend to use normal adhesive, and heatshrink when its just going off ::)


Yesterday, I was fault finding an electrical issue on a large ride-on mower. Where was the fault? Yup, a (manufacturer done) crimped connector.

I'll add at this point....

"Technicians" at Audi are not allowed to solder wire repairs. They can get a disciplinary should they solder anything.

I'll leave you lot to mull that over  :y

And that's a surprise why?

BMW Fitters weren't allowed to remove the sump plug during a service :-X ::)

It's not a surprise when you hear stories of what can happen when things are soldered  :)

Ps, before this turns in to an OOF witch hunt  ;D ;D ;D I don't care what anyone chooses to do. It's your car so you do what you like. I personally choose the shrink/crimp things cos soldering is tricky for me. That's not to say I can't do it. But these things are so much easier  :y

If taped up rather than properly sealed, you can get corrosion at the end of the solder, if in a harsh environment. Or poor quality solder used.

Otherwise, generally not an issue...  ...certainly better than scotchloks or those silly bullet/spade type crimps :y

I usually take the car to work and get a professional to do it. I struggle to solder with two hands, Christ knows how Webby would even attempt it.  ::)

From my (limited) experience of VAG cabling I would suggest that the quality of the wire used is such poor quality that they would be wasting their time anyway........

Agreed, I'm bored of repairing the fragile looms on Mrs VXL's Alhambra now.

Scalding hot solder gun held under my "small arm" 😂 Twisted wires sat carefully on top of iron. When all wires hot enough solder flows through. But it's a right ball ache if they are thick wires as takes ages to heat. These heat shrink connectors are done in a couple of minutes even by me 😂
