I'm for linear controllable power instead of turbocharger kind of surge..

I too also have this noise. And coincidentally, the MyVi I have also exhibit this noise. All my older Toyota don't have this sound.

Belakong or Taman Midah

My friend Vios S also leaking. He told me quite usual and replaced twice (I can't recall front or rear) and also he drove rough.

Meanwhile, mine Vios G dugong no leak at the moment (hope not in the future as well). I also drove roughly.

Both car are 1st batch of Vios dugong @ 2007.

I'm not sure about the 'DUB' sound of his car but, mine (Vios & MyVi) definitely have the 'DUB' sound when going over sharp/pointed hums or going over them fast. I wonder whether this 'DUB' affects locally assembled 'Toyotas'.

Where did you service your car? Just taking note to avoid it in the future.

Anyway your car is really in serious trouble.


My dugong already 60k km. No problem except:
- going over bump *fast* and got the sound 'buk'.
- when parking on slanting surface (head top, rear facing bottom), I jump in the car and I got 'nyek nyok' on rear suspension.
- very dirty rear wind screen - no idea why it gets dirty so easy compare to all the other cars I 'owned' before.

How unstable it is?

Hmm, I never got that. Did you modify anything? Like adding amp, changing ICE? Where did you service the car?

Humps, bumps, up/down hill, traffic jam?

I used to have avg 70km per bar.

After I shift to different place with hills, more than dozen humps before join into main trunk road and relatively more cars, my per bar mileage become 50km.

Your HID (the white light mode) using the lo-beam connector, is already acting like hi-beam (using both lo & hi beam focus point together) glaring other driver. Meanwhile your yellow-light-mode is just making use of the hi-beam connector (but positioned not in either focus points) so you can hopefully skip JPJ road block. Simply said, these are 'cheap' HID kit.

And no, the yellow-light-mode is not like your previous stock yellow light - it is never brighter than stock.

Tire question:
The dugong Vios speedo actually show faster than it really is (eg. 90km/h on the speedo is 83~85km/h on GPS).

Is it ok to have 195/65/R15? (stock is 185/60/R15).

Not all 'dashboard' sound are the same. The one I had, is some wire not being properly tied/attached to some 'wall', so it knocks on the dashboard generating continuous small knock sound when unlucky, it happens intermittently.

So I complain to the SC (Toyota Midah branch, cheras), and now the sound is gone.

Another problem is the belting problem only on cold start (no such noise on warm start), irritating squeaking noise. Complain to the same SC, and fixed already.

Last problem, is the absorber sound, where randomly, sometimes has low 'grok' sound when going over humps. I've tried going humps with low or high speed (and many different ways), and the result is intermittent (this is just to prove I'm not going to humps too fast or it is a faulty absorber). Complaint to the SC on my last service, they did something to it (tighten bolts & nuts) but still occurring. I stay at a place with lots of humps and up & down hill. So someday it is just silent & normal, other times it just keep happening.

For the belt I don't know what they did (Toyota don't let me in the service bay and see) - just complain during service, then ok already.

Absorber, even not raining also got the sound. And not always got the sound also.

Ok thanks. I don't mind appearance anyway.

I was quoted RM260 for XM1 195/60/R15, and PS3 195/55/R15 for RM280. Anybody know a cheaper place? I was told PS3 doesn't have /60/ and it is just RM20 extra compare to XM1.

How much differences are there XM1 vs PS3? Quietness is my top priority & performance is secondary.

For engine noise, add more padding on the firewall & hood.

Don't worry. Even cars bigger than Vios and more expensive than Vios also uses rear drums.

The 1st gen vios is every 40k - that's for ATF-IV.
Dugong Vios the last time service agent told me is every 80k - that's for WS ATF.

But some foreign country (if I remember correctly, is Taiwan) said it is lifetime - requires no replacement.

My Dugong Vios G I insist change on 40k once. Felt no difference at all - and my feeling is, it is slightly worse than not changing it compare to my bro dugong Vios J.

So... just follow the service schedule will be alright.

1. Drum do need two 'pad' replacement - they often call it 'skin'. It looks like leather belt. About 4 to 5 inches long.

2. The one you see (outside) is just cover.

3. Maybe is too much brake dust collected, hence the spring or the mechanism stucked.

Wait until you goes beyond 140km/h and the tire noise will drown every other noises.
