Will it hurt the car starting in S5 immediately

After cold start and drive off?

Its been a habit of mine to hit the increase button twice immediately after pushing the start button. It could be first start of the day or 10th start of the day...I just automatically put it into s5.

Is this bad for the car?? Or makes no difference?

I do that too. As long as you don't got WOT and fire off rapid downshifts before engine/tranny get warmed up, it should be fine.

Are you serious a drivelogic mode being "bad" for your car? Ugh. I hate to sounds too harsh but with questions like this it really begs the question if you should be owning/driving a DCT equipped M3 (or a MT for that matter...).

Hey, he drives 65 in the 'fast' lane regardless of the speed of others around him. Of course he should be driving an M3.

I hit the M button immediately after I start the car with Power on and edc on Sport. Helps me backout of my drive which has some grade to it and then not bottom out when I get to the street. It wont hurt anything.

The DCT mode doesn't matter initially. Just try and keep your revs low until your car warms up.

Me personally...I put in D2 until the car warms up. Then I'll hit the M button.

Wtf kinda of question...

Sorry, but questions like that make me think that you have never in your life driven anything sporty or you have money to waste and perhaps you thought the m3 would make you look cool.

^^ wtf kind of response is that?

I get the OP's question and don't see why some of you seem to think it is stupid... S5 shifts significantly faster and harsher than, say, S3. When the transmission is cold, it isn't crazy to wonder whether this is extra wear/tear on the internals. Sometimes downshifting in S5 (or upshifting on harder acceleration) can be fairly abrupt. Maybe extra wear/tear is insignificant but I can see why you might have the question the OP had. Man, gotta be careful with questions here!!

I always drive in S5 when the weather is nice... I just take it easy for the first couple of kilometres until the car warms up a bit.

Not exactly. S5 only shifts significantly harder when accelerating hard and shifting at large throttle openings at high rpms. There is also some evidence that S3 actually shifts faster than S5. Don't confuse smooth with fast they are separate variables. If S5 would do any damage BMW would have put a "lockout" on it just like the way the car has a variable redline depending on engine temperature. The cars normal 8400 rpm redline with a cold engine would obviously hurt the engine, thus the built in protection.

Secondarily, from a fellow trusted long term forum member, it has come to my attention that there are many similar posts from this OP. Who coincidentally claims to have a huge house and garage stuffed with something like 6 cars. Pictures were promised to settle a little debate on that and the pictures have never been provided. It all points to nothing but troll-ism...

Greetings Swamp. While I see your perspective, it should be noted that he did post pics of his cars in this post only to delete them a short time after. He has also evidently bought more than one car from GOLFFRR. I consider him a real forum member, just not very self or vehicle aware.

Its not going to matter as long as you keeping the revs low during the warm up period...on a cold start phase the gearbox shift maps are in any case slightly altered to account for the cold gearbox oil (and cold engine).

Hmm, that's wierd. I wonder why he deleted them.

Still would love to see some pics of that awesome spread he has with the big garage.

I disagree with these - it's the delta at high speeds which changes, not necessarily the force. And it couldn't be faster at S3: if it's slower at S5, then what's behind the change in settings?

Agree with all.

Even if true others here will almost certainly benefit from having the question discussed. The process almost always yields something positive.

Have to second this. I drive in S5 all the time as well, and it only shifts hard when you want it to. And for example, if I shift at quarter throttle and low RPM, the gear change is very smooth with the shift barely being perceptible. I typically drive like that through my neighborhood (who doesn't? No need for full throttle or even half throttle in a residential area), and sometimes even onto the main roads around my house if I am not in the mood to push the car.

As a corollary, what happens when you do a 1-2 shift in S1 at redline? Or for that matter a 2-1 shift @ 5k RPM? I don't use S1 so I can't say, but I'll bet it is far from smooth.

Correct. It'll hit fairly hard at the end - it just takes a slightly longer time to get to that point than it does at S5.

Feel like being a smart ass this morning, you guys mind? It was a rough night anyway.
So, would it hurt my car if I take 3 right turns first thing in the morning? See my commute to work mandates that I make 3 right turns before a left turn. Would that cause uneven wear to my tires, suspension and or brain?

Can't believe you didn't use Search for this issue. It's been discussed sooooo many times before.

Anyway ... you gotta make sure PSI in the right front tyre is up @ 47 before you hit the sack the night before. Although you'll find a lot of people who think that's not enough.

Op's question is better than one of those: "what color should I get?" threads-- if we help you choose the color of your next car, do we also get to decide where your girl sleeps tonight? Starting in s5 shouldn't have any adverse effect on the car.

Mine didn't. Typical disreputable dealership behavior. I'm going to BMWNA. Maybe a lawsuit. We need to start another thread. Or a poll.

Dude, you got screwed!! Mine is 2011 and it came with a miniature GTR and a nude picture of miss America.
