Noise / rattle when engine cold

Post by CrashQai » Sat Nov 10, 2018 8:24 am

Hello all. Nice to join the forum, looks like it will be a very useful resource.

I have an n-connecta dig-t 1.2 petrol, registered early 2017, that I bought this summer. I've noticed that when I start the car from cold, for the first five or 10 mins until it warms up I hear a vibrating / rattling noise at around 1800-2000 revs when accelerating. The noise seems to be coming from somewhere in there behind the steering wheel. Whilst this is happening I also feel like I'm getting a little less power. The engine kind of sounds like it's struggling, and this possible contributes to the perception that I get less acceleration. Am I imagining it? Is it a fault or just some body or trim rattling?

This is really starting to drive me crazy! Anyone else experienced similar? I have seen a number of posts about various noises and rattles but I'm not sure any of them exactly match what I'm experiencing.

I have booked the car in to be looked at. Obviously it's under warranty, but I can't help worrying that they're going claim they can't find any fault and then charge me for the diagnostic. Someone reassure me?!

Funny you should post this. My QQ is booked in for next Friday for the exact same noise. My rattle occurs between 1.4 - 2k revs. You can hear it best in second hear (road noise is less). When looking under the bonnet there were no obvious signs (apart from the air intake not held on to the slam panel at the front). Is your rattle also present when your foot comes off the accelerator?

Thanks for your reply! It's reassuring to know at least I'm not alone in this. Yes, I should have mentioned, it is indeed strongest in second gear. Do you also feel any difference in power or do you think it's just a noise? I'm booked in on Wednesday so I will let you know how it goes

I'm not sure if there is a direct correlation between rattle and lack of power, but there is very little power below 2k from the 1.2 anyway I feel. The engine itself is prone to issue though. There's a huge pinned thread about the engine issues and even a newspaper article about it. Have you had a chance to listen to it pulling away from a pedestrian point of view? It sounds really ill.

If you could get back to me on what the garage says, it would be much appreciated. I'm getting charged £114 just for the diagnostic alone (just like yourself), and don't want them to come back to me and say 'yep, sounds all good'. Arnold Clark for you really.

I've not listened to it from a pedestrian's point of view. I'll definitely get back to you on how it goes. Do nissan charge for the diagnostic regardless of whether a repair is covered? This'll be my first experience of nissan servicing. My assumption is that "diagnostic" just means they'll plug the computer in and go and have a coffee. If it is a case of some engine part or other rattling against something else simple due to poor build quality that's unlikely to get picked up by the computer I suppose... I'll try to have a chat with the an actual mechanic when I drop it off. Wish me luck

This is my gripe exactly. If there was an electronic fault assisting with the noise, it would pop up on our dash surely. You're right too, they're just going to plug it in and read any codes that crop up, not any real effort going into it. If there was a fault, the eml usually comes on and that prompts a diagnostic.
I'm quite sceptical so I think they're just trying to get as much money as possible for the 5 minutes they're going to take up using the diagnostic machine.
