Auris 1.4D Owners - Dpf Issues?

[Steve_75]

Hi, just popped over from the Yaris forum to ask if anyone here had any issues with what appears to be regular DPF regenerations?

My Yaris (and another) have had issues where every 350 miles or so, the instantaneous economy suddenly drops (like from 75 to less than 40) and at standstill, you can smell burning (smells like paint being burnt off a new exhaust), lasting for 15-20 mins.

The other Yaris has had increased regularity of this (every 100miles) and an increase in oil level.

I thought seeing as we shared the same engine, I'd post here to see if anyone had the same experiences and whether your dealer has told you it's normal or managed to stop it happening.

Hello Steve,

I've had an Auris with the 1.4D4D engine for over two years and 75k miles now.

Your right about the regeneration happening about 300 miles, and as you say, you can tell it's doing it because of the smell and the drop in instantaneous MPG,also the idle speed increases to about 950rpm, it seems to take about 10 miles to complete, if you turn the engine off during it, it seems to have to wait a while then start again.

I've also found that it can seem to want to regenerate more often if your a steady driver, or if you do lots of long 60/65MPH runs, as I do, then what I do is wait until it's doing a regeneration, then drive it with plenty of revs in a lower gear then normal for a few miles, but make sure it's safe to do so, this seems to blow the DPF out and it go's back to regenerating every 300 miles or so.

By the way, when I first noticed the increased idle speed I talked to my local Toyota Garage about it and they did not know what I was talking about, so I presume it's something that not many owners have asked about.
