How curious! said Alice "exploding ECUs; whatever will they invent next?"

So if the design of an ECU is so crap that it can blow itself up, how can the same company that designed it have the nerve to charge £600 to replace it with one of a similarly crap design?
So, 10 years, £600 (+vat) = £60 pa (ditto) = £1.20 p.w. (inc vat) for ECUs - forever.
It's not an awful lot if you budget for it - but a car manufacturer should tell you "- oh, BTW, apart from the things you know will wear out and need maintaining, we've put some special gremlin boxes in, just to keep you guessing. So, for all the bits of stupid design that we just couldn't be bothered to fix, get a tin and put, say 20 quid a week in. To be on the safe side, because we'll put prices up without improving quality, call it 30 quid a week. Don't worry about it - think of it as a kind of "stupid tax"

So, over and above all those understandable expenses like tyres and brakes and servicing and so on - all with VAT on the top, if you are the proud owner of our vehicle for 10 years, you should be paying about £10K for our incompetence. Don't worry, it's industry standard, we all do it - it's part of our business model. The government positively encourage it."

"Well, I wouldn't like that at all" said Alice. Disagreeable girl.

Moral of the story: when you buy a complex thing like a car - it doesn't end there - it's just the start. You've just given your back door keys to the manufacturer; if they run a bit short, they can always nip in and help themselves to a few bob.


There's nothing you can do, so bend over.

Sleep well.

Follows on from my thread about TD5 conked. The ECu has a couple of components blackened,, soot inside the case, PCB damaged. No sign of an external (to the ECU) cause. No oil in it, no water ingress. I'm told (by Alive tuning) that they are seeing more and more aged TD5 ECUs failing. And the price of a replacement leapt up last year, rather inexplicably.
Logical conclusion: the ECU has a limited life span (10 years/117K miles) and is unreasonably expensive to replace.
Somehow seems contrary to the Landrover philosophy, putting on fancy (and expensive) electronics that can let you down. You should be able to fix it by the roadside, get you home (or to civilisation) at least.
 
If I've done this right, I've attached a photo of the exploding culprit, along with a picture of what I think it is (or similar). Interestingly, a device similar (though more recent) is advertised: "IRC's Surface Mount Resistor Meets GR1089 Lightning Strike Specifications" (this is the company's HSF series of resistors.)

Either way, if that's a resistor that has blown up, it had a terrific amount of power through it. A colleague opined that, to include such a hefty resistor there, the designers must have anticipated a fair bit of power there on occasions.:eek:

So, I wonder what that circuit did?

I also wonder (and will investigate in due course) what might be the extent of the damage to tracks and components round it - it could even be that the board could be repaired - though I'm still wondering what else failed to actually put that much power through it.

Well I did warn you.... How about the WXYZ switches on DII autos that seem to fail fairly regularly.... The first one I replaced was less than £100 several years ago.Recently they have been ramped up to approx £430 + Vat.And yes,they are not an improved design - just the same ****e.
LR have adopted the policy of ramping up parts prices that fail - without improving them.
