S49 Recall is really BAD!!

Not sure on actual size difference, but rolling circumference was apparently 7cm different. I'll measure exactly and post when time permits!!

Have 2015 GC and had 30,000 k service and patch done about 4 weeks ago. Have done 2 long trips, 900k and 1400k, since and notice 1.5-2 litre /100 k increase in fuel useage but no fan noise. Been slow to engage reverse a couple of times. Haven't noticed fans. Local service manager asked us to drop it back for a reflash when I've got time!! Interested in DPF info.

Further to the fan issue, I noticed the day I took mine home from the up-date the engine power does not drop immediately when you take your foot of the throttle. I have a reasonably steep drive way and when going up this now I need to be ready to brake as the car keeps driving for a further second or two at about 1500 rpm.

I can see mine do this on flat ground also, by putting the car in drive and rolling along at idle engine speed, if you press the accelerator slightly (bring revs up to 1500-2000rpm) and take your foot off the engine keeps powering for a further second or two. you can also see this on the tacho, watch it when you take your foot off...

Does this happen to any one else?

Yep mine does this too but not consistently. I notice it most when coming out of my leased space in the CBD, going up the ramps the car appears to hold the revs for a second or so when I back off. Sometimes it holds the gear entirely while driving aswell like sport mode does but in normal drive mode.

Hopefully the S91 patch will fix this (what dealers are calling S49 update)
