What is the sound of ETM when the engine cuts out?

Hi,

Does anyone know if ETM should give squeaky noise when the engine is off?

I made experiment, started the engine then disconnected some sensor which made engine stopped and I heard that there was squeaky noise coming from ETM. I have recently replaced my old ETM with new one from dealer and now suffering. I cannot start the engine when its cold in the morning (I need to try for approx. 30 times until it starts, it starts for a second then cuts out), I don't know if it due to connector of ETM or the ETM itself, it behaves like there was not ETM connected, I have observed that strange noise coming from it.

Is it normal or the ETM is damaged?

Thanks,
Tomasz

Anwering my own question, nobody seems to know...

This is normal sound, the same with my OLD ETM.

Yes the ETM makes a high pitch noise when turning off , it resets itself to the start position ... Its unlikely an ETM problem would prevent starting as its only and air restrictor and in the base position which is spring loaded it will start and idle ..

Thanks for this post. Recently I noticed my S80 T6 1999 would produce this screeching sound sometimes during starting and always when turned off. I did not have much peace until I saw this post recently...thanks!!!
