[src]

Hi,

My Nissan Micra (2003-2010) 1.0L Petrol started vibrating mainly at front driver side even while its not moving as long as engine is ON.

What I observed is..
- Vibrations are at front - Driver side mainly
- Vibrations are there even when car is not moving
- More Vibrations when starts pushing accelerator and when being removed from accelerator legs pedal
- Not always its like a wave.
- No relation with either brake or hand brake as vibration are there when its released as well
- Car is reasonably maintained - Now ~70k mileage
- All fine till recently driving this car for last 1.5 years

What could be the problem..?? Cam chain/Balancing…………..????? Any info from Motor experts or other Micra owner or mechanics..please..

Hello did you ever find out what caused this? I have exactly the same problem that you are describing and need to fix it I think it’s the lower engine mount but just wondering what you discovered.

Oi,

O meu Nissan Micra (2003-2010) 1.0L Gasolina começou a vibrar principalmente no lado do motorista dianteiro, mesmo quando não está se movendo enquanto o motor estiver LIGADO.

O que eu observei é ..
- Vibrações estão na frente - Lado do motorista principalmente
- As vibrações existem mesmo quando o carro não está se movendo
- Mais vibrações quando começa a pressionar o acelerador e ao ser removido do pedal das pernas do acelerador
- Nem sempre é como uma onda.
- Nenhuma relação com o freio ou com o freio de mão, pois a vibração existe quando é liberada também
- Carro é razoavelmente mantido - Agora ~ 70k quilometragem
- Tudo bem até recentemente, dirigindo este carro nos últimos 1,5 anos

Qual poderia ser o problema .. ?? Corrente de came / Balanceamento ………… .. ????? Qualquer informação de especialistas em motores ou outro proprietário ou mecânico da Micra ... por favor ..
[/CITAR]

Eu tenho o mesmo problema e meu motor foi retirado e reparado,
e as vibrações continuaram

Did you consider using a long screwdriver on the engine and listen for a better clue of the origin of the unwanted noises? And a rear engine mount is a good candidate. If your engine tilts noticably when pushing the gas pedal, I personally would look for a affordable replacement, even if it is not the source of your issue with your engine.

If using a screwdriver does not give much clues, you might want to use a crow bar on a running engine and see what tilt it needs to make it go away, of course you might dent and scratch your engine bay a bit and be extremely careful with the moving parts, a crow bar hurting you is something to take in consideration. If you don't feel confident, try asking someone to help you. Also, a screwdriver gives a similar safety issue. And for your car, be confident about what you can not put under pressure, you shouldn't use weight on cooling lines for example.

And if you have the occasion to have the same make and model and engine from a friend without the noise, a screwdriver is your best bet, even if you have no experience with listening to engine noises with a screwdriver.

The issues I was having were: if I was moving in first gear i could accelerate but then when I took my foot off the accelerator and let the engine do the braking it felt as if the engine moved slightly and the gear got stuck slightly so when i down clutched it would be quite hard to pull it out of first but then after that it would go back to normal. That was the first sign. Now it has progressed and I can hear the engine noise though the chassis. I can sit out of gear and rev and it will make a vibration quite loud though the chassis sounds like its coming from front right. If i am driving it rattles all the time anything above 1.5k revs. if I down clutch while doing say 40 the noise goes away. If i turn hard left the noise goes away for a couple of mins but then comes back again. it sounds like a kind of rotational vibration as if it is picking up from the drive shaft through the engine. tyres are all balanced no feedback through steering. when down clutch when moving dont hear the driveshaft noise but maybe that could be because the engine isn't driving it? Any help would be appreciated. 1.5dci K12 micra sport plus 3rd 2006

I read your desciption as a completely worn rear motor mount and then when the engine noise comes trough the chassis I think about chain issues.What noise is audible when the car is revved a bit sitting still? Please click on the three dots with the arrow down or post a youtube link with the noises with a car sitting still. Nissan stock motormounts are quite soft and if you can tell your rear motor mount gives when stomping the gas, it is worn. Based on a worn rear motor mount your gearbox shifting stick to the gearbox can give you a lot of complaints. The engine and gearbox and the driveline with the wheels and suspension is kind of a floating entirety, some small tolerance overridden can end up with big issues somewhere else while something simple and small is the culprit but start with the motor mount, that is in ninety percent of the cases the part that is responsible for a great part of your description if not all but to be a little more certain I'll need to hear the sound that comes with your media file. Please record from all sides and move around your phone gently.
