Will unresolved eccentric shaft sensor codes cause harm over time?

Atx328 · 12-02-2017, 01:52 PM

I have a 2011 328i that is currently throwing Eccentric shaft sensor codes obtained via the Carly app. What are the possible long term effects or harm that I could be doing to my engine?

The car starts up just a little bit rough when cold with a tiny RPM stumble around 1K idle at first. Then it goes away and there are no driveability issues.

About a month ago, I swapped out the eccentric shaft sensor because I was getting wild rpm fluctuations and the sensor appeared to be bad. I got a OEM style replacement and there is a chance that it isn't working 100% properly - but the idle start up is sooooo much better.

I also swapped Coils and VCG when I installed the new sensor. I have new plugs from about 3 months back.

Thoughts?

That's how mine started and within a few weeks it would go into limp mode after the first start of the morning.

It'll go into limp mode before anything breaks. The car starts using the electronic throttle plate as a backup.
