Hi everyone,

We have an used (petrol DIG-S manual 2014) E12 for about a year as our first car ever.
It was serviced once or twice per year at Nissan dealerships before we took it and now has 75.000 km on it.

As a total newbie to cars, I am a bit concerned about the sound of the car's engine after watching some videos about engine knocking/misfires.

Do you think that this idle sound is bad or just normal?

(It also had squeak sound for ~30 seconds when started at cold then disappeared, but I did not record it.)

The last oil change was 5 months ago.
I bought an OBD II reader but did not see any fault code.

Thank you in advance!

I checked it about 2 weeks ago and it was in the middle.

I will check it now but I guess I have to wait for the engine to be cold again. Thank Sineu.

The oil level is still at the middle between min and max.

It sounds a bit to me like tappet knock.
Thanks, I never heard of tappet before. The sound seems fine at the start or during driving, the bad sound is only clear in idle after some time.
When looking at the workshop manual of Micra dig-s, the symptoms are pointing to camshaft bearing or tappet!

The manual says engine teardown is required to check or adjust the valve clearance. I don't know if an indie garage could do it or must be a nissan dealership.

ANY mechanic worth his salt would be able to do the work, just use a reputable indie garage.

OK, I will check around for a good garage and let you know when it progresses.
The good (?) thing now is that Belgium is still under partial lockdown and we don't need the car now.

It is 5W-30. However, I am the third owner of this car so don't know what happened to the car before.

I visited our local garage today and two mechanics said that sound is normal...

It doesn't sound normal to me, there is a definite sound of metal "chatter" from something. With the old OHV engines it would have been the tappets for certain, but modern engines , it could be anything.

I will look for another garage when I have more time. At least I don't need to use it now...

Sounds like the noise my Mazda made when the Timing chain had stretched. Can be a problem on these engines.Needs further investigation before it gets too bad.

Sounds fine to me, and sounds like our Micra DIG-S!

The injectors on these engines seem quite noisy and will contribute to some of the noise you are hearing.

The squeak is likely to be the serpentine, however worst case scenario is one of the tensioners need replacing.

There is a thread here: DIG-S belt drive noise | Micra Sports Club - I got the belts replace first, then the tensioners gave up which started off initially as a 'rattle can' type sound at startup.

Thank you for the information.

About the squeaking noise, I have replaced both belts for one month. So far so good, and hope that it won't come back soon.

I have 2014 1.2 petrol acenta premium. I had some funny knocks and noises under acceleration, with rough idling, after checking all the sensors, finally inspected vvt oil control solenoid, highly corroded removed cleaned up casing and engine contacts, making sure nothing gets into the business end and holes ,
replaced now runs no knocks or funny noises, and runs very smoothly when idling, hope this helps.
