You might want to change the tires first if you have not done so..the tyres does give most sound.

I have done roof, doors, wheel arch with pillars foaming.
This improved the door closing, some improvement from doors. But now the tyres getting old and harden, so not comfortable when driving above 60kph.

Next target is the floor and 2nd level door sound proof. Should be DIY when have budget and time.

Last time, i did the roof, doors like 2 days (split job)... then balance sound proof pads on the rear door and wheel arch.

Then 1 day for the foaming of A pillar and door sills.

Ya...it is kind a big tasks... see how la.

Foam...last time i bring in batches via my friend.
It is from europe side..but forgot what brand as no brand sticker.

Now donno still can get or not.

You may one to test one thing.. when it is completely disaster.. try get your passenger to open the window and have the phone out there.. see if works.. if yes, then i suspect the tint.

I use rainX...since long time lo.

Every time when going outstation i sure maintain it..going 100kph on heavy rain without much using wiper.

My wife's car also put rain x as she requested....work best on all other windows too.

There are other brands too..

I apply to all windows too and also the side mirrors.
Rinse with water after applying. You may need 2nd application since first time applying.
I am not sure about others...for me, i needed as it gives me clear vision.

Ya...i using silicon blade.so far no judder too.

U can find in hypermarket too...or mr diy for cheap one...
Jusco has it too..

Hi guys, happy new year!

Would like to check with you all...anyone planning to change their tyres and rims to bigger one?
I am looking for your original rims.
New model or alza rims....please PM me.

Thx

Sharing some work done...

I have done front floor sound proof. DIY, but found the driver seat side floor is wet, not sure where the water comes from.
I check front behind the paddles, nothing there, checked bottom undercarriage, is fine too. Passenger side is clean and dry. Need to check again later.

The sound proof is from front floor till the back row floors. Also did 'under coating' at 4 wheels areas. Took out tyres, banana and 'paint' the inside.

Overall improve little where the high pitch from tyre noise is improved. more subtle sound.

And today did changed the rims and tyres too and further improved liao. I changed to 195/55/15 too.. no upgrade in size. the rims is wider 7jj instead of 5.

I will check again. Thx.

Updates: the buzzer connected to the side and rubber seems fine. I have painted with undercoating..so later see if still wet floor.

I have balance sound proof materials..so use. I would need a mat to cover on top of the pads.

Many ppl tried and pay over thousand to do where outcome not as expected. so DIY as i diy the doors, sills and roof previously.
I did not take pix as my hands are very dirty that time. It took me 5 hours just the front floor so called.

Now i have done partially, i would know what materials needed too later. Dont expect it will be as quiet as lexus.
Hope my source or friend still would sell to me...

It is rubberized spray for under carriage...can get from ACE.
I took out the front banana and spray. I did not spray on the banana as i have a foam paf behind the banana already.

The rear, just jack it up...clean, dry and spray.

Ya.. I have a friend that has BLM.. it is bad when first time sit on it. the CVT is all the way.
Tyre sound is worsen as he change the tyres..forgot what brand already.

I did one Saga BLM too, my the other friend's car, diy together. Did the level 1 on doors, foaming 4 sills, rubberized coating on 4 wheels area and a foam to block sound on the fender side.
It is improved as he mentioned. The doors better now, much solid feel but there are gaps near the windows area which need further improve if needed.
I told him to change the tyres first if can, but he wanted to see if this sound proof helps.

If you gonna do it, take off the banana, you can see many gaps from front wheel to the front doors area. What you can do is to get a big good sound proof (about 3ft by 0.8ft) and block that area..
I got this from the friend of mine it is like a compacts foam with different compression and slot into that gap. Then paint the rubberize coating on the needed area. Also if you want to paint the banana leaf..can too.

Just aware not to simply spray where the 'holes' will spray to engine side. you may want to temporary use a tape to cover the big holes first then take it off after.

You need like 2 cans of the coating.. each about rm22 and lots of OLD NEWSPAPER.

What level of temperature you set?
Is your setting of air channel is front vent? Meaning no mix of leg area or upper vent?

Just to follow up.. any progress on this? what OBD2 you using? Which model as many out there, most said not for alza

Thx Bro Colin for getting my odb2 BT and torque running.

Cheers.

Range not really accurate. If your trip A or B, full until blinking, how much?

Try have the range reset and let it calculate again.

You might need to have your car service like spark plug, filter, throttle clean if needed.

As what Cleaner said...driveshaft could be the issue as the 'knuckle' may have worn out.

AT....it could be the connection / wire from ECU to gearbox having issue. check that part first or change that wire first if not expensive.

Some myvi having this issue and changing the wire sort it out.
