I guess I forgot to tag XiuKeong as well.

Please let me know if you need details. I can PM in LyN. Thanks!

Hi guys. Recently got my M3 pre facelift . Open delivering only i notice there is no button to open the boot from outside. Only by key and from the driver side.

Is there an add on for this?

Hi bro, atf what brand and specs u use so is the strainer. Better still can share what workshop u go to to get it change and price ...

mazda atf fz

A question to all skyactiv owners, do you face a 1-2 second rattling sound (something like "tek tek tek") when lugging the engine around 1600-2000rpm range on a hot day?

Is this engine knocking or i need to get the timing chain tensioners and/or all the associated pulley system checked?

Sifu, I am going to collect my M3 GLS tomorrow. Any common defect and issue I should take note / check prior of collecting my car?

most important check for scratches

and all the neceeesary tool box and spare tire and etc

if no rush can check power window and etc

but those no worries, can go back anytime

but for scracthes once car out from showroom consider sold , can't complain about scratches d

Is this a sedan "feature"? My HB can open from driver side and button on the boot, but not from the key.

I have exactly the same problem. More likely to happen during hot day or after a spirited drive or going up a slight incline. Less likely to happen during the first drive in the morning. I think it's engine knocking, but 97 not solving the problem.

I complained to them during my service interval, they just say engine is dirty and sold me a bottle of mazda fuel cleaner. Seems to have reduced it abit, but not completely eliminated.

Which batch is your car btw? Mine was the earliest ones, March 2015. Booked before it was launched.

Is this ECU tune for Mazda 3 Skyactiv done by Torque Foundry worth it? They are charging RM1,100 per tune.

It looks like low end torque has undergone a significant increase. From the dyno curves alone (I suppose these are wheel figures) it should give a more spirited drive. Maybe experts like wkc5657 can comment more.

Same to M3C FB. Just check your "Others" inbox in FB. Sometimes the message will route to there.

What petrol are you using by the way? For me, i pumped BHP RON95.

I got mine at nov'15, should be similar batch to yours. If i see the dash temperature 34C, then i prepare myself for that irritating rattling. Really didn't expect a car that is not even 5 years old to have this kind of issue. Wonder how will it affect the longevity of the car since our batch is 3 year instead of the new 5 year warranty.

Darn, need someone locally that can do data logging to double confirm. Will dump in a bottle of injector cleaner soon. Maybe will experiment with petron RON100 and dumping in octane additive.

Any other owners facing this?

Seeing the graph, seems pretty fitting to their company name, the torque increase will be noticeable for normal driving! The stock components are known to withstand almost double the power and torque numbers. Quite worth the money if they can let you test try to have an actual butt feel.

The main concern is, will this affect fuel consumption for the better or worse....and whether is it too aggressive that will cause engine knocking considering mine stock already experiencing possible knocking.

I'm on Shell 97 or BHP 97 usually, occasionally BHP 95.

After putting in the mazda fuel cleaner I have been on nothing but Caltex 97. Now on my 3rd full refuel the sound is less frequent and less audible when it happens. It's helping somewhat, but I'd like to have the sound gone altogether.

We get alot of torque at the 1500-2000rpm zone, so I guess timing is most advanced there hence the knock. Sometimes can hear it at 6000rpm when pushing hard, though this one is a single 'tick' vs the low rpm 'tick tick tick'.

My warranty only 6 months left, I hope nothing major breaks haha. It's not throwing warning lights so i think the computer still thinks the knocking is not at a dangerous level yet.

OR it might not be knocking at all and something else, do share if you have it figured.

Hi!

I was informed by my colleagues that if we don't service our car on time (according to the schedule), it will void the warranty for the car. Is that true?

I don't have this problem even during traffic jams on hot days and I use Ron 95. I really doubt it's knocking as you still have the sound even when using Ron 97. Ron 97 should be way more than enough to prevent knocking. It can't be asking for Ron 100 can it?

When knocking occurs the ECU will automatically retard the timing to protect the engine. So again I think it is not knocking.

And another thing, if your engine knocks you are going to feel the jerk or vibration, not just hear it.

Are there any other ill effects besides the tick tick tick sound? Could it be a normal engine sound which you are overly sensitive to?

For the torque improvement the price seems worth it. But dyno is one thing, the proof is in the driving. Hopefully they can let us test the car after after tuning and reverse/refund if we are not satisfied.

Anyway, have to wait until at least my free servicing is over. Now at 55K km.

Definitely not normal engine sound, and most of the time, it happens on hot afternoons. Hence, the initial culprit maybe knocking. The best reference of this sound is similar to some older manual cars, when lug/load the engine, got a short moment of ticking/rattling sound.

If it is not knocking, i suspect could be the timing chain tensioner. A more far fetched possibility could be due to low quality engine oil/lack of lubrication on the VVT system on certain operating parameters.

Anyway, will request for the service advisor to check on this when i go for my suspension fix (again, 3rd time).

Politely ask lor..."abang, can let me test before and after? Nevermind la....i belanja you goreng pisang even if i dun wan"

Anyway, the process is pretty easy, i looked through the remapping manual (with mazda openport), very fast process to upload new mapping.

True.. It’s normal and same applies to warranties offered by most car manufacturers.

I don’t think anyone prefers to get paid after doing the work based on the customer’s “feels” that it was done right. Feels are very subjective.. Numbers are not..

Knocking is an out of sequence combustion producing a random power stroke which upsets the smooth power delivery of the engine. If you don't feel anything like the engine stutter or jerk it's probably not knocking.


The work is really not any big effort for the tuner. If they are confident about their tune they should have no problem getting payment from satisfied customers. If the difference is significant enough it's not even necessary to do a dyno; the owner will feel the difference and pay up willingly. If the owner feel that the difference is insignificant just revert back to stock and both sides lost nothing.
