In my Holden Cruze manual it says that if the regen light comes on to keep the engine over 2,000 rpm and keep driving till the light goes out. I know you don't have the light, but you don't need big revs to clean it.Well it let you go past 5k in manual mode? I've often wondered if there is a limiter on there. I know I like to "push" the car when I'm in a regen. I feel like it cleans out the system better.
I guess I should have composed that sentence a little better (it's confusing). I don't actually take the car up to redline during regens (close though). My philosophy is that during regens, the exhaust gases are extra hot. A few near redline pulls during this time should really help get the gunk out and clean those sensors off. Since I started doing this, I have not had one sensor related CEL (10k miles). To each his own though. I was curious about the 5k limit because in manual mode the shifting isn't instant and when you shift, it still seems to let the RPMs build another 3-500 before the actual shift takes place. Because of this I always shift around 4k RPM (during regen pulls) because I don't want to redline the engine. Also, sometimes you just forget you're in manual mode and the next thing you know your darn near 5k.In my Holden Cruze manual it says that if the regen light comes on to keep the engine over 2,000 rpm and keep driving till the light goes out.

It does not shift, based on my experience.I can relate to forgetting it's in manual mode and getting close to the redline. It doesn't take long in first gear. When I took it up to redline, as I recall, it hit the governor. I wasn't there for more than a second or two, as I don't really like taking it up that high. I can't tell you if it was exactly 5k or not. I've had some GM's in the past with the 4T60E (Grand Prix's and Century's) that would still shift out of first once you hit redline (even though the shifter was in 1). I don't know if the CTD will do that or not.
