Flat Spot at around 2400 RPM

[Riv39 Advanced Member Find all posts View Profile Close Riv39]

Just been for a few test drives in a 2nd hand march 2011 150, I don't think there was any hesitation - what's the easiest test?
The only thing I noticed that it loves to drop to 1500rpm @ 80km/h.....not sure which gear that is must be 5th?

Anyway, it seems a very low rpm & you get the feeling that its labouring just a bit....

Can Toyota check if a particular car has had a TSB applied?

Cheers

Richard, sounds like the update has not been applied. The dead giveaway that it has been updated is the fact that it will not select 5th before 60km/hr. It no longer labours at all it downshifts readily.

Toyota should be able to tell you if its been done but as per above it is easy to tell for yourself.

"We so far so good" On delivery I had asked the dealer about the hesitation issue no one had heared about it, the answer was if there is any problems tell the mechanics on the 1000km check and they will look up this issue, Anyway completley different drive experience than my 120 series, taking a bit to get use to the revs dropping right back and 5th being used alot, this is where I expect the good full ecconomy comes from, yes there is a little labouring here and there but all something to get used to, it very quiet for a diesel wife has no problems going from petrol top diesel, finally now its in the garage I'm getting used to the shape.

Doug sounds like it's lugging and probably doesn't have the update.

Thanks again for TSB number.... service tech got shitty when quoted, maybe thats why they never washed it.
Got ECU reprogrammed and auto changes are better, pity they couldn't fix the 1500rpm rattle, found that out as soon as I drove out.

Dougy, PM sent. My testing of the software update has reviled that if you select 'S' mode the car will not change to 5th before 60km. I think it's the same for D but I need to experiement a bit more as I normally use S mode.

Because it's the diesel engine that has the hesitation at 2400rpm not the petrol.

Well folks, I've had mine updated today and it's a totally different car. It is far more responsive and there is no hesitation at all. To be certain, I've retraced my key journeys where I've noticed it the most and there's no problems any more.

If it affects the fuel economy, so be it. I'll be happier to use more fuel for better performance than I had, and besides, if I pay more attention to my shopping dockets I can save 8c at the Woolies servos!! I'm sure that'll offset the difference.

Whilst I had the TNS number, there was no need to quote it. They gave me a copy of their internal document re the change details too.

(Got the mud flaps done too and they're a massive improvement).

I had mine reprogrammed about three weeks ago and the hesitation/flat spot has gone. Before the fuel usage was telling we around 9l/100K but now it is around 11l/100K. Anyone else experiencing this?

Yes there is a difference. IMO 'S' mode is a little better than 'D' as it seems to hold lower gears a little less. So far I reckon a approx 0.5 - 1l/100km around the city. Country driving is no different.
