My Ride: UK 2005 530d E61
![Default](https://5series.net/forums/images/icons/icon1.gif)
I seem to have a weird issue with my Steptronic 530d (Mar'05 UK E61). It's like the car goes into DS mode without being in DS - the rev limits for changes are higher and it refuses to engage D6 automatically. I also notice a change in exhaust note - almost like the exhaust is 'blowing' slightly. I think DS is used from cold sometimes to have the engine/catalyst warm rapidly. However, I had this weird mode occur in the middle of a 200 mile motorway drive at 70mph+ last night. The mode seems to self-cancel after a while.
I've seen transmission 'slam' posts, etc. but I can't find anything similar to this on the forum. Does anybody else have the same experience? Is this some legitimate mode for some purpose? Any views/comments appreciated (as always!).

This is normal behaviour.
About every 1000 miles, the particulate filter goes through a "burn" phase to remove residue - this involves closing off some valves or something like that.
It happens on my car too - sounds like you've got a V8 under your right foot

Thanks very much for the info.

I'm very surprised they don't include a section in the user manual on this. The first time it happens it's *very* disconcerting.

Skip's post on the dealer advice was a little worrying!

My objection is that manual gearbox cars can not have the option of forcing the gear to have a higher engine rotation!!
Last week I asked my dealer to completely reset the memory of the car and reprogram everything. I will keep you updated.

I don't have a problem with the programmed 'clean cycle' ... it's just a bit unnerving when your not sure why the car is behaving so. I agree with browellm on this one and say that the biggest fault here is the lack of info in the manual.
The lack of D6 is not really noticable unless you're on the motorway ... and even then I found that you can still manually select D6 and the 'box will also go into D6 if you set the cruise control.
