335d running in
Discussion
Sooo... what's the general consesnsus on running these cars in? Are the engines tight when they come out of the factory, and do you get better MPG once they've got some miles on? If so, how many miles did you need to do before you started to see a difference.
Got my E91 335d a couple of weeks ago now and really enjoying it. Very much a squirt and go, easy to drive, sensible car.

Right, ive always run in new engines before.
Not this time, i hammered my 335d after 100 careful miles. (car reg'd march 07) and was picked up with 5 miles on the clock. the next 95 were gentle etc.
Relatively
She used a bit of oil for the first 4-5k but has been fine since. Now got well over 30k and she has been re-mapped to.
She did loosen up after about 8k miles and again after approx 20k.
Also please bear in mind, the car will very likely have been thrashed already. Dock staff do thrash new cars (I have witnessed this) and also BMW dealers do take them for a spin also.
So even if your new car has 2 or 10 miles on collection they will be HARD miles into the redline and full throttle, thus rendering your ''running in'' process pretty pointless.
Just give it some welly.

Have to agree with Carlos on this one. However you treat it it WILL have been thrashed already. I have always given my cars the beans right from the off, once they are warm of course. Never had a engine problem once in 12 new cars all treated this way, BMWs, Fords, Vauxhalls, Renaults.
I suppose the big question is are you keeping it long term, ie longer than the warranty period? If not give it some, if you are then give it some anyway. Engines are so protected these days by engine management systems its hard to really do them any damage unless you redline it from cold with no oil.

How can a 335d be thrashed around the docks for Christs sake? Have they got a two mile runway to get the car up to speed? I don't think so.
Your car may have had a dyno run at the factory under controlled conditions but that may be it. Our car hadn't even been off the dealers premises when we picked it up with a few miles on the clock.
It is difficult to abuse a 335d during the break in period as the performance available is so great (same as with many high performance cars). You will be seriously breaking the speed limit before damaging the engine.
Giving the car the occasional bit of of beans during running in isn't going to hurt it as long as it is up to temperature and you allow the turbos plenty of time to cool dowm.

Dock workers move them from compound to compound and load them on and off ships. I have seen them driving like complete c$nts, admittedly it is only for a short distance.
Something you need to accept when you take posession of your band new car with 50 or so 'delivery' miles. Its not been wrapped in polethene and baby'd as you would like to imagine.
It must be seen a perk of having one of the s
ttiest jobs in the world.

Yes fox man, the 335d was ''officially'' my fathers then, but with my full use and with a good hint that it would be mine not long after, i still hammered it from now. I do give a stuff about my car. I never thrash it from cold and always let her cool down. But i still hammered here for the ''run in''!

The bmw book says 1250 miles, don't go over 3500 rpm.
Which is what I did, well nearly, it had the odd foray up to 4500 but only once or twice and never for more than a second or two.
Lets face it, running a 335d in accoring to the book is hardly a hardship, I know they are run on a dyno and it was driven at the dealers but I have the thing for three more years and so want it to be as good as I can get it.
Of course now it is run it it is getting full beans most of the time..
Great car.

Yeah, give em full welly from the outset because obviously they have been screwed hell out of in the
first few miles before you got it,(REDLINED!!)Or maybe not!,but no matter because we know modern cars
do not need running in properly anymore because oil and engine tolerances are so much better than they
used to be! Wonder how many people buying second hand would choose hammered from the beginning over
nicely run in,Just a thought!
