DS(sport mode) strain on engine?

hi guys,
i got a e90 325i lci auto, wanted to ask your'll in (DS)sport mode do i have to use the paddle to change the gear or will the car change it just fine? i accelerated to 6.5k prm on 2nd gear & had to press the brake cause of some prick who just crossed the road the car decelerated very aggressively from 6.5k rpm is that ok? no strain to the engine? in sport mode the car really is loud, i can hear even the exhaust, feels so ncie compare to normal drive mode. Its ok to decelerated like that no harm to the engine? sorry i m a newbie to automatics.

Thanks..

Absolutely fine.

Just make sure that your oil is warm (note - oil, not water).

more than fine!...the auto gearbox is very "conservative"...I tried to kick down a few times even tho i know it will rev up to 6/ 7k rpm...the gearbox wouldn't let me...

Like anything else that is mechanical, if worked hard it will place more load, stress and strain on the components.

We could debate whether it is good or bad, but hard use typically results in a shorter life. Would be much the same for the drivetrain with a manual box as for an automatic.

Makes sense to override the auto function, if it is just revving when you want lower revs.

The car will still change gear for you in DS mode, it just hold the revs in each gear for longer.

I doubt that you have done any damage to the engine just by breaking hard - if everything feels okay then you should be fine.

Thanks for the help guys, this is my first auto & tried "DS" mdoe & was blown away, it makes the 325i much more fun to drive then in normal "D" mode. yes i noticed the "DS" mode barely takes the car to its max redline 7k rpm. It mostly changes the gear on 6.5k rpm. I had to apply the brakes when the autobox was just about to upshift. The sound that came from the engine when i hit the brakes was a nice sound, Been driving the octavia earlier for years so not useto this engine note. Thats why thought if its okie.

Thanks..

325i does make sweet noises when the revs get up ,up to that point its very tame but with a lot of revs it does come alive.

yeah absolutely, the 325i responds well to hard revs. BMW set the electronic limit of these engines, well well short of the mechanical limits. As long as you don't go around driving it constantly on the red line, it should have no negative effects on the car.

My mums old car a 328i, had 150k on the clock when i got rid of it, i would thrash the hell out of it once or twice a week, and it was the strongest engine around even though the car around it was falling to bits.

The 325i is interesting though, it seems to have two personalities, below 2000rpm its silky, smooth and quiet. It lets you short shift, has enough torque to get around and feels civilised. Then above 4000rpm it starts growling, opens up and it's a riot.

Enjoy it!
