Anyone else have results post software emissions update?
I had my 2015 6speed done this week. I filled it after the work so when I get through the tank I will have a good baseline for MPG changes as I use Road trip for every tank. I have just over 20k miles on the car.
As was said in this thread the difference in low end torque is pretty impressive. Before the fix the engine was basically gutless below about 1500-1600rpm and then came on strong at about 1600. I always thought it was just that the engine couldn't spool up the turbo below that speed but clearly that was incorrect. Now if you give it some gas at say 1000 or 1200rpm you will get a little bit of turbo lag and then the engine pulls well. Where you would need to downshift for second around fairly slow corners you can keep it in third and pull out of it easily. You don't get the rush at 1600 as before because it was already pulling harder lower down.
Just getting the car moving feels different too. The RPM doesn't drop as much as the clutch is engaging and the difference in low end power just seems to get the car moving easier.
Regen seems a little different too. In the past I have only seen it start a regen when the car is fully warmed up. It seems to be more aggressive about regen now. I had it start one when the engine was still far from fully warmed up and it happened to be a short trip. On restart it immediately jumped back into the regen.
Idle is also slightly different. After it gets a little warmed up it always just dropped down to idle speed (around 850 RPM or so)very quickly. Now it sometimes seems to hover slightly faster (around 925rpm) for a few seconds before dropping down to the normal idle speed. This is with AC off and not when doing a regen.
Last thing I am waiting to see... previously the power of the TDI always felt variable. Sometime it pulled like a freight train, sometimes it didn't. After getting on it a few times it would then start pulling hard again, felt like it had a variety of different maps it was running on and occasionally it was on a fairly weaker map. So far I haven't noticed this after the fix but I have only driven a few hundred miles so far.
So far I am very pleased with the changes.
