€4000 euros plus tax to replace the module that contains the fuse. Insane.

The ford transit custom PHEV costs £4500 to replace the timing belt. Access issues mean dropping the hybrid battery and parts of the sub frame. Compare with the mk8 transit, i've done the wet belt myself on that and it requires no special tools (well, i bought a specific crank pulley puller for £20) and can be done in a day on the driveway. I believe in some markets the replacement schedule is down to 6 years for the new phev due to all the wet belt failures on older models.

So far my favourite brand to work on has been Mazda, the engineering is very thoughtfully done with consideration for repairs.

I hear a lot of praise for toyota but it's from people who haven't worked on a car themselves rather than mechanics and they must be talking about toyotas from a bygone era because i'm not impressed with a 2019 corolla engineering at all, specifically various parts of the electrical system. I believe that was the most popular car in the world at that time.

Tesla is remarkably well done. Simplicity is under rated. So much so i bought one with the intention to keep for a looooong time.

Is it insane? I'm working in this field, and I know how quickly you can come up with such a number if you are BMW and you are deathly afraid that someone will get electrocuted while working on your car, driving it or rescuing someone in a crash. It's a safety and liability issue, where they go to great lengths to actually re-certify a battery after crash. The whole thing is setup so, that even the dummy electricians in an average BMW shop can safely certify that this battery is still safe. It's a lot easier to kill yourself (or someone else) when working on a EV Battery than wet belt. Also a lot harder to repair said battery than wet belt. And that goes for all EVs and manufacturers that actually care about people (Tesla, demonstrably does not).

Yes, it is insane. It's a fuse. They must have some stats on how often those things need replacing and it should have been accessible. The customer has - when they buy the car - absolutely no way of knowing what kind of surprises like this there are hidden in the vehicle and besides, it kills the second hand market so you can only trade your vehicle to a BMW dealership where they can absorb those costs for a fraction of what it will cost an end user. BMW is a crap brand in spite of their reputation, we've had one leased Mini in our company and it is the very last time we do business with BMW, that thing was more in the shop than out of it with electrical issues. A friend had pretty much every BMW ever made since he got wealthy enough to afford them (car enthusiast) and his experience is much the same, but he keeps buying them.

Fuses are not items that should be replaced normally - they are self-destroying emergency protections for the electrical system.

If it is protecting that end users can plug arbitrary loads into, that is one thing - but this doesn’t sound like that?

Why did that fuse blow? Because if that is not addressed, it’s likely to just blow again.

Fuses are necessary on any electrical system, and especially in a car, which is an electrical shitshow (floating ground, high-voltage and high-frequency interference), fuses blow all the time. Granted, usually on a well-maintained and new car it happens very rarely, but saying that it's a catastrophic and concerning event is dumb.

What sort of cars do you drive?

I’ve never had a fuse blow on a car less than 20 years old, and then it was due to shorts due to damaged insulation and bad grounds due to corrosion, which are legit problems that need to be corrected.

Also, unlike breakers, fuses are generally immune to issues with HF interference and the like - they work through basic thermoelectric effects which iron out all but the most extreme issues. If you’re moving multiple amps in a situation described as ‘RF’, or ‘high frequency’ in a DC system that’s not just noise!

That’s a real problem that needs fixing!

Not fixing the underlying problem behind a blown fuse (or constantly tripping breaker) is how your car (or house or whatever) burns to the ground.

Or you have a Lucas, in which case my condolences.
