	Bad caps « on: August 29, 2021, 07:23:20 AM »

So recently Ive had a handful of early 4 cylinder ecus that have bad / leaking capacitors, and accompanied with "terminal 30 voltage low code" and according to a customer they had cold start issues on a completely bone stock car and cal. Replaced caps with new ons and mailed back, all issues resolved with the terminal 30 voltage low and no more cold start issues. I have no additional technical info to add as I havent looked into it further then this.

Happens all across the world of electronics. They don’t make em like they used to! A cap should last for at least 20 years. There’s even a wikipage on the plague. https://en.wikipedia.org/wiki/Capacitor_plague

It might be a good time to start a company in America. Make caps great again.

Extremely interesting; do you have a list of caps you had to change? ME7.5?

Back in the 1990/2000 they made some motherboards with caps that lasted a few years (:

Why would you use some that hold 5years, if the device is out dated in 2years? Hehe
-when they manufacture cars today it’s for a period of 6years and 200.000km or some like that, if the car will handle more then that, you just need to be happy Cheesy

hehe

This has literally nothing to do with conspiracy theories.

The formulation for caps was just bad, many motherboards and monitors back then blew up in warranty period etc.
Some ECU's were also affected.
I don't think I ever needed to change caps on anything since that was over.

I am pretty sure that no modern ECU is going to have leaky caps within 20 years of manufacturing time.
