2014 Corolla Altis - Technical, Features & Use

[CrimsonAltis]

could the knocking due to suspension? it should not be worn at 20k (not even 100k I suppose) but could be manufacturing.

one of my old cars had damaged bushings. it makes 'clack clack' sound when going over speed humps.

 

not much rubberband feel for me so far. but apart from the shudder, I do feel during nearly constant speed sometimes the transmission wants to downshift then quickly upshift again, giving a pull and release feel. but this is rather mild.

 

indeed it seems Esso 5000 is more powerful than SPC 5000.

the pick up with E is stronger than S.

But I still managed to get average of nearly 16km/l for the round trip from office-home-office since last night about 45km total. so overall the fc has not shown any reduction . but road condition is a bit better this morning (not rain).

 

Not sure if it's workshop issue, if after 1st to 3rd servicing they keep telling me they didnt spot any error or fault...and they never heard the sound (had the engineer followed me on test drive, but route was too short to have the sound). I gave up asking them to check after the 3rd servicing, next 20k servicing probably head to Leng Kee already as Woodlands is closing up.

 

Fuel, used to pump esso95 but switched caltex 98 now. From experience, it does give me more pickup. Even more so when i add the techron concentrate, accelerate lightly and the pickup is much stronger (but the effect will wear off after clocking a few pumps). There's a new more concentrated techron (red label), yet to try that though.

 

I don't check my FC, as im heavy footer. Hovering around 10.9-11 (expressways mixed with normal roads, and traffic jams too, those kill FC) and i do at least 100km daily commuting to and fro home/work/kids.

 

You pump tyre pressure high high is it ? 

 

Nope... drove out of West Coast for the first time, rumoured they pump extra into tires due to long term storage...probably 230- 250?

 

Afters, i follow the metal label specs at the door, 220, 210 (occasionally i put 230 for all four if i know i have no time to check for short period of time....as losing air dropping to 190+ to 200...affects FC considerably i noticed). 

Sound still appears while switching lanes regardless of air amount pumped.

I think you need to do a video and send to them.

I recall a video that the steering will stiffen up at higher speed.  Maybe you can "experiment" with that.

 

Pressure loss is common.  It depends on your usage pattern.  I need to pump about every 4-5 days. 

[ConnorMcLeod]

Caltex 95 for its cleaning properties.

 

 

 

You "night" rider is it ? 

Eh.. I asked because I am trying to understand if maybe your issue is due to the ATF too cold.

Honestly, my car is too new to have dirty throttle but I just ask because nasty things can happen in manufacturing and contaminate the throttle.

 

not night rider.. .7am & 7pm weekday drives on so-called expressways ;)

 

pumped tyre pressure is 220 spot on  last night. left rear tyre needed to pump more, meaning last few weks limping on 3 tyres. must monitor for leaks in the next 1-2 weeks with the left rear tyre, else uneven wear jialart.

weekly is very frequent. do you always pump at the same place and still see significant drop in pressure?

 

last time I used to pump once several months and still tyre pressure can still maintain . and I liked to feel the road so I +10psi when pump (so pump to 240)

Usually same petrol station, same petrol pump and same air pump. 

Perhaps it is my sensitivity to pressure drop of between 5-10 kPa.

The pressure drop is inevitable - usage pattern. 

 

I just hope the carbon build-up on the Altis is not as much.

U v gd. Takes gd care of ur car.

 

Ya i also want to make sure my car can see at least its 15th bday.

Ya, only obstacle - CVT. 

[ConnorMcLeod]

Ya, only obstacle - CVT.

This is one of the reasons i had when choosing between elantra n altis, also price.

 

With so many altis on the road, should be easy to get spare parts or 2nd gand cvt years later so no worries.

Back to tech stuff.

Went to showroom n drove test drive car n my car with SE. He concur there is a shudder with mine. So this is not my driving style problem. Will continue to monitor tyre pressure n response between spc n esso.

 

They use shell95 when deliver car.

 

For the rear defogger, he told it the wire pattern around top few inarounof the rear window is antenna. So i need accessory shop to shift lower my rear cam. They should know the issue i thought but haiz. Dont say i am only one install rear cam so far !

Glad that BM recognized the shudder issues. If u can feel the difference between Esso and spc 95. Wait till u try Caltex and Shell.

Exactly.

It was the SE. Will need to repeat with the service supervisor.

[ConnorMcLeod]

Just for info. My millage is 600-650km a week. So my guidelines of 2 week actually translate to 1200++km travel before the shudder disappear.

Good luck bro.

I am now experimenting with those cheap rubber that provide some soundproofing. It helps a bit but tire noise really cannot do anything.

Bro u try under record setting and then select impact sense

Where did you get the rubber for noise insulation? Saw on qoo one from korea. But there was no info where n how it is installed. Yes tyre road noise is quite obvious. Was told the michelin 17" is wer weather tyre n tend to be noisier. Having said that it has been raining almost since i collected my car so i am glad i got this tyre which is grippy.

[Altis2016]

I get it from Taobao. I think it is not so good. Initially can feel that it help but after a week, it seems to lose its effect and it is not so sticky. I bought some original 3M tape to redo. However, I do find that it keep the dust from the car especially @ the bottom of of the door. I always find exhaust black soot there for my case after a week. Now I do not have this problem.

The Korean type I bought from Qoo10 is a add on type to my present rubber. It is suppose to stick to the car body aro the doors while taobao type stick to the door itself.

Just received my order of the Korean type. Will let u know how it goes after I install it.

You v determined to sound proof your car. Please share the korean one's result. Thanks.

Only now then have the chance to read thru the thread. I pump 35psi 250kpa (front) 34psi 240kpa(back). Tire noise is lesser and no shudder till now except for the brief moment @ 8k. Mileage now 15.5k.

what is the kpa mentioned on your side panel? is yours 16" or 17" rim?

 

using your case as reference to decide should I over inflate a bit.

noticed there was engine braking while driving down hill on expressway today. it happened a few times that the engine was braking for 1-2 secs then release while all along i depressed accelerator at the same level.   now I recall SE ask if possible I was experiencing engine braking... hope this means a known tuning trick.

My side panel recommend is 33psi (Front) & 32psi (side) for 16" I think. When I did my 5K servicing, BM lower my tire pressure to the standard. I find the car has a lot of resistance and tire noise is very.....loud. I insist that BM restored the car to the condition that I first collect the car. When they go thru the test and find the nothing wrong, I discover that they lower my tire pressure. BM explain that all cars shipped with overinflated tire pressure as they do not know how long the car will be in the warehouse. The service guy happen to own the same car and he told me he himself do 35 & 34. Since the pressure suit my liking. When the weather is very hot, my tire presssure can go up to 36 front and 35 back.

 

I do not experience this engine brake u explain. My every day route has downhill on expressway. The steepest one is PIE join KPE tunnel to TPE. I normally maintain the same speed until it reaches the top and let is cruise down slop.

Hi Altis2016, thanks for elaborating. Will check over time how increased tyre pressure influence the drive..

[My5t3ry]

bar is for better stability and handling. you will feel the diff when cornering or even straight road. you can read up more online abt the bars. currently BM only offer trd frnt tower bar, some of us hve mixture of trd & UR or juz UR bars which quite popular and cheaper (if u fixed in msia). SG price is slightly higher but this is all to individuals.

i have change the stocked Rear Torsion/sway bar to TRD one which is much thicker. this was ordered via ebay frm usa. note that the steering will be stiffer when more bars are added. basic setup will be the Front Strut/Tower Bar plus rear Anti-roll bar (UR 16mm & 19mm).

for comfort go 16mm. 19mm stiffer but better handling

 

Hi Bro,

 

Thanks for the explanation.

 

I plan to  add the trd front bar during my 2nd or 3rd service from BM.

 

Do you know if I were to add other TRD or UR bar to the car will it void BM warranty?
