I've bought for the Yeti mostly to put a new AGM Battery on, but it's seems to have some useful functions.

For anyone whose used one, Do you know:-

 

1) What should the dpf soot reading be (2017 Yeti) and is it worth triggering regeneration manually ?

2) There are 2 battery options - one is can bus and I guess the other is the monitor ?

 

Thanks

That depends on how many kms it has driven since the last regen, dont get hung up on the number as its an estimated value in any case, there are VCDS parameters for calculated and measured the former is away with the fairies and the latter is not measured but calculated from the DPF differential pressure, that is the only parameter worth being concerned with.

 

Soot level should be close to zero after a regen but the increased back pressure on a higher mileage engine will raise that to say 6 - 10 grammes, regen is triggered around the 22.5-25 gramme figure, it varies.

No point unless the DPF warning light comes on in which case driving the car through a regen is preferable, if succeed in getting the chocolate teapot VCDS to do a static regen then you are a better man than me!

Ok. Massive irony or coincidence - the light came on for the first time in 6 months today (and went off).

Have you done lots of short journeys recently and had interrupted regens?

 

I had the light twice, once when I was rebuilding the car after the write off, never driven more than backwards and forwards in and out of the garage, frequent start ups (as you do with a new toy!) and allowing the engine to reach operating temperature.

 

The second time was the beginning of the confinement when travel restrictions were the most rigid and very short local journeys.

 

Both times probably coincided with the car wanting to do a regen and failing multiple times.

Might have to go out for a 'race' against my other half in the Impreza Turbo. That should clear out the crap!

Fitted new AGM Varta battery today - it was the original on the car (yellow paint on bolts) but was getting a bit chuggy when cold starting after 8 years.

 

The Carista was really easy to do the Battery registration with (monitor and CAN bus). 

 

Impressed so far.
