I'm not sure that 0W-40 is the recommended grade, which is 5W-30 I believe. I have topped mine up with Castrol Edge 0W-30 and noise still occasionally rears its ugly head.

Anyone else got a view on this?

According to my Handbook the recommened oil is:

Mini Longlife-04...... which is Castrol Edge 5W-30

Alternatively: MINI Longlife-01 FE or ACEA A3/B4.

I've thought for a while that the viscosity of the oil might be to blame, if this is the case then it would mean using 5W-30 for Spring/Summer and 0W-30 during the Winter

Please

check this site:

It's a dedicated site abt cold start issue, the site is ---new--- and there is ---no post yet--- but it's a good opportunity for a survey / poll about the chatter!

As I read into the previous post, regarding the possibility to solve the problem while selling a new facelifted MINI, I think that a major flaw (causing seriuos damages) will be fixed during the actual production, in order to avoid the substitution of thosands of engines, with a sharp loss for MINI/BMW image and profits!

Otherwise, in case the chatter will be fixed only during the facelit, I think that it's only a noise problem without any particular consequence.

Guys I can't say i have got the cold start noise after watching the video clips but on my MCS Club (March 2008 build) and I have got a slight tappety sound since new (only done 800 miles). I say Tappety because it sounds like it comes from the top of the engine, could it be solenoids or something like that?

- Anyone else on here got this type of noise?

Incidently I find the engine quietest after just after a cold start!

Thanks for that Brizio81 but another thread was posted earlier today about it.

Some of us have signed up, but when you click on Forum you get an error message ' Template Parse Error' . Hopefully they will sort it out soon.

aaargh, sorry I noticed it too late.. However now the link it's more "visible" thanks to bigger text

I wrote a similar message also in NAM forum, in order to gather more people as possible...

The sound could be only due to direct injection, it's typical for MC-S-.

Try to find on YouTube or into previous posts through this thread, the clip with the noise we're takling about. No possibilities of error after hearing that...

Also bear in mind, the weather is becoming warmer so the chances of the noise being there is going down every day. Unless of course we get another cold spell...

Hallo!

Have your dealer been already informed abt the return of the noise even if the new engine has been installed? Was he surprised abt it?

Thanks

I was on the phone at 8.55am to give his Monday morning a great start...

I think if I could have seen him, he would have had his head in his hands....

Still no noise ( well apart from the knocking on the nearside front but that's for a different thread)
Has anyone else had the full timing system change which worked only for the noise to return later?

Hi Sarah

I had the full timing change just over a months ago and the noise returned within three weeks. Also the idle is now rather lumpy (almost like the timing is slightly out).

I emailed Elms in Cambridge a week ago.

" With great disappointment I have to report that after a month of trouble free motoring since the entire timing assembly was changed and with things were looking genuinely promising regarding the longevity of the repair/parts, unfortunately the cold start noise has returned with vengeance during the past week."

Customer service manager replied saying the info has been passed to the BMW regional manager and he will liaise with his technical dept. Still no word as yet from them on the next stage of this ongoing saga.

Not been on mini2 for a while. As some of you know, i had my engine replaced last October and have the noise back on the new unit. Listening to whats being said to you all sounds like a "Stock answer" from stealers. They are doing nothing about it, so dont kid yourselves. Not convinced that this 0-30 oil idea is gonna work although i have some and new filter sat at home for me to try (worth a go i suppose).
I asked my stealer last time my car was in for rattle if they did here it, what was the cure???? ....... He said...... THERE AINT ONE!!!
I've logged onto the R56mcs.com site tonight, so lets hope we can sort somat out now, as i do love my R56 JCW MCS.

Welcome back Specky 1.......sorry to hear the noise is back especially as you had a new engine.

The R56MCS forum is not working correctly at the moment !!

[S8RAH]

Hmmm, oh well, I'll just wait and see. For the moment, please can I still just be a little smug?

[brgc00perboy]

I think that the timing chain may be stretching over time and this coupled with the tensioner not working correctly is causing the noise. There have been many cases of Nissan engine timing chains stretching to the point where the cam haft sensor throws a wobbly.

When I got the car back from the dealers a month a ago the car idled sweetly after the total timing change. Now that the cold start noise has returned a week ago i have noticed the hesitant idle.

Does any one else's R56 MCS have an uneven idle (even when warm?). It's like when you sit at the lights you can feel the odd disturbance through the steering wheel and pedals.

Just went out to the car about 30 minutes ago and started her. Ambient temp was good so hardly any auto choke required. Idled at around 800rpm but felt as though it was missing slightly (hesitance).

A good test is to open the driver door and see the drivers window vibrate randomly!

If the chain had stretched would this not mean you would hear the noise at least every cold start?

We are only talking 6-12 month old cars and nothing with excessive mileage.

How old were those Nissans?

yeah just checked on you tube and it seems like its a 'normal' noise so I guess its the direct injections as you mentioned. It definetely is not the cold start noise. ;-)

Seem to affect lot of Nissans (micras, sentras, almeras)

Timing chain question [Archive] - Micra Sports Club

YouTube - Micra noise?

YouTube - Noise? Timing Chain Guide?

2007 Micra, timing chain/tensioner noise on starting engine - RAC Motoring Forum

"worked at Nissan for ten years and we have long experienced timing chain problems

The most common engines that sufferd from chain sretch were the almera and primera models (X99-54 plate) fitted with QG15 and QG18 engine.
The K11 model (1993-03) never sufferd from chain stretch (they just used to snap!)

The K12 micra (your model) is fitted with a nissan timing chain and we did have problems with the early K12 chains stretching, which causes loss of power (due to the ignition timing being out) and you may get the engine warning light on which usually flags up a fault with the camshaft position sensor, again this is due to the timing being out.

The noise on start up has been common on the micra since the first models from 1993. It is noticable more on cold mornings, as soon as the oil pump starts getting oil to the top of the engine the noise goes.

I would not be to concerned at the moment about you're car, I know they have fitted a modified chain on the later models so I wouldnt worry untill you notice running problems with the car and/or engine warning lights.

Make sure it is serviced every 9,000 miles or 12 months (whichever is sooner),
to keep ther warranty valid incase the chain needs attention in the future"

VCT problems also sound similar

Thanks brgc00perboy.

Someone else I see suggesting the use of a different grade of oil:

"... I would get some nice thick oil & do an oil change & leave as is. Nissans engines are known to have rattling timing chains ..."

I know there are MINI2 members who are 'oil experts' ... have any of you any views on using more viscous oil and how this may have adverse effects on the engine, and affect the warranty?

Cheers.
