Hi

Just bought a 2001 Y reg K11 1.0 S

28K genuine mileage, FSH to the year dot, not a spot of rust anywhere - drives like a brand new car - so I'm very happy, and loving my new Micra.

However, since I looked into Micra's in more detail, it seems the knowledgeable owners (you guys) are preferring pre 2000 models as they are more reliable.

Is this purely down to the Bosch throttle body/coil pack engine, or are there other problems with them too?

I see mention of Renault parts creeping in to post 2000 K11's, but is this the case? Are people getting confused with the K12 when they say that?

The only significant reliability issue with the post 2000 K11's that I read about are Bosch t/b related - not about Renault components failing.
 
Thanks for the welcome.

Are there ANY Renault parts in these late K11's?

If not, what is the basis of the "post 2000" comments about reliability that I've seen posted quite frequently?
 
Hello Steve. Welcome. Renault did not become involved with Nissan until late 2003, when they pumped in 49 billion dollars French government really) to stop Nissan going bust. As a pre-curser to this deal Nissan had to agree to use Renault parts, hence the trouble with the K12s (sorted after 2010) so your k11 will NOT have any French crap in it.
The throttle body problems seem to be associated with poor maintenance, particularly lack of oil changes I have read ( I change my oil and filter every 5k) so change your oil regularly and you should be ok.
Other than that, these cars seem to be ultra reliable, and are easy to own - enjoy your micra.
 
Thanks davyboy.

My new K11 has had oil changes every 12 months, regardless of the very low miles covered - and I'll be continuing that, even though I won't be doing more than 2,000 miles per year at most.

Actually, I've seen conflicting recommendations regarding the service interval for oil changes - some say every 6 months, regardless of mileage and some say every 12 months.

Every 6 months (which for me would be after 800 - 1000 miles) seems a touch over cautious, but if it's necessary I'd do it - a lot cheaper than a new throttle body.

I've also read that the Bosch throttle body doesn't like lots of very short journeys - which is unfortunately the majority of my driving - although I do get a bigger run now and then, to blow out the cobwebs.

If these kind of short runs puts me at higher risk of developing problems, then maybe every 6 months would be wise?

6 months is just to keep fresh oil on the timing chain, I was always recommended to by the Nissan techs at work. For the sake of £20 for an oil filter and some oil its worth piece of mind :)
 
its the k12,s that had the chain problems tho eh, k11 chains are pretty bulletproof when you compare them to the later inverted chains and old timing belts
 
I'm lucky to have a Nissan specialist independent garage about 10 minutes walk from my house - get's loads of great reviews from Nissan owners, some of whom travel 50-60 miles to bring their car for servicing.

So I'll ask his advice re oil changes, but I'm erring on 6 months now.

I'm sure every 12 months would be OK in the early years, but as the car gets older it might be wise to step it up to 6 months - we all need a bit more maintenance as we get older.

Oil does not degrade, it just gets dirty, 12 months would be ample in your circumstances. You are correct though, not just micras, but all cars dislike continual short runs, the occasional blast does them the world of good.

Mineral oil degrades, fully synthetic doesn't supposedly, but if the engine has run semi or mineral oil and you change to synthetic the seals can shrink and cause leaks apparently.
 
Oil moleculesare round and completely flexible, no matter what you do to them, they will return to shape and keep there ability to lubricate. Only when dirt enters between the molecules is their ability to lubricate compromised. Some of the oils sold today are re-constituted, ie, cleaned and sold again. That's what I have been taught, and read over my lifetime, may have changed due to me being around a long time, but, I've never seen anything to contra that.
 
Back on the subject of post 2000 K11's

I was originally hoping to get a 1.3 engine, but the 1.0 S that I found was so great I couldn't turn the opportunity down to buy it.

Anyway, I noticed on Wikipedia that the engine specs show the 1.3 engine as not changing to a coil pack in 2000, like the 1.0 engine does - is that correct?

Does the 1.3 litre in these post 2000 K11's have the same bosch t/b and coil pack as the 1.0 litre?

It's not classed as a 1.3 in the coilpack, it's a 1.4 if your wanting to swap. I think the code is cga3 for a 1.4 iirc?

What about the post 2000 CG13?

I know the post 2000 CG10 and CGA3 had coilpacks - but if the CG13 didn't, then presumably it doesn't have the troublesome Bosch throttle body?

There were no post 2000 CG13, the coilpack t/b. Injectors. Ecu. Manifolds, loom. Rail, cyl head etc are all different

I'm confused now. I've seen 2001/2002 reg 1.3 litre k11's for sale - and you say there is no post 2000 CG13 engine?

My mechanical knowledge on all this is virtually nil, as you may have guessed!

Just how they've been advertised. Even though the later CGA3's are stated as being a 1.4, they are not as they are 1348cc, which is still a 1.3.

Yeah, some countries say ANYTHING over 1.3 is a 1.4, whilst some countries class it as a 1.3 because its closer to a 1.3 than a 1.4... Ford are a bit funny with their 1.25 though :)

Ah, so you are saying that the ones I have seen have actually been 1.4's (with the 1348cc CGA3 engine) - NOT true 1.3's with the CG13 engine?

It was just the owner thinking "1348cc - let's call it a 1.3"?

It essentially is a 1.3 of course, so I can understand why some people might say that.

All makes sense now, if that is the case - although the Wikipedia article engine specs do kind of imply that the CG13 engine was produced up to 2002.
 
Going back to one of your earlier questions though, now that you're aufait with the post 2000 coilpack engines. Everything is the same ie injectors, t/b, sensors etc. The flywheel is lighter on the 1.0l engine(2kg lighter) but fits. Obviously the main internals are different sizes.
