I just don't understand how an ECU could make much noise. All it is, is an integrated circuit with small amounts of electrons flowing through printed microscopic circuits and transistors. Electricity at this tiny level doesn't make much noise but lightning does. for example. If your desktop computer were switched ON but your had removed every single cooling fan and electric motor, the computer would be virtually silent. It wouldn't run for long before overheating though and I wouldn't recommend it.

I have seen many engines in my life. The relationship between humans and reciprocating engines is illogical sometimes. People start to expect too much out of them. They are complicated pieces of machinery and stuff is bound to go wrong. Considering how complicated they are, they are a whole labyrinth of moving parts and systems that are all operating independently of one another. Great is their complexity. At any moment certain parts of the engine are activated seamlessly without the driver ever knowing about it. A little noise is normal. You've got all kinds of fluids operating under pressure and at different temperatures.

Considering the great complexity of these engines. It's only natural that there would be some unexplained noises. And in some ways engines are no different than computers. Where the unit is programed to operate a certain way under certain conditions etc. Although I enjoy working with engines more then computers since it just seems more rewarding. I can't stand offices and cubicles and all the stale air inside to contend with.

A bad engine is almost like bad computer programing.

I plan on keeping up with this technical problem. I'd like to find out what it is.

No car company is perfect. Even BMW makes engineering mistakes at times. They once made a BMW motorcycle that had the fuel tank located close the the engine in such a way the the fuel inside the tank would start to boil from the high heat!
