335i bogging down

THE335 · 12-21-2011, 05:02 AM

Hello everyone,

I was hoping someone could advise on the following;
I have a 2010 E92 335i DCT (N55)
Yesterday whilst doing about 90km/h on the freeway in sport mode & in 5th or 6th gear i put my foot to the floor.
The car shifted down to 3rd, the revs went up to about 5000rpm & then immediately bogged down. As if the DTC had kicked in, or like I was on the rev limiter & didn't upshift. I then tried it again from around the same speed & the same thing happened, it stayed at about 5000rpm & didnt upshift and was bogged down and jerking.
I then tried flooring it from a standing start & everything was fine.
Ps, The car has travelled 30,000k's & I also have the BMW Performance upgrade since around 20,000k's.

Any thoughts would be appreciated.

Is there a speed limiter on the car, i.e. won't let the car exceed 120km/h or something?

any non OEM tune in place? Sounds like a flat spot or the ECU throwing in some retardation

Did you try it with DTC off?

No speed limiter that i'm aware of. I have owned the car from new.

Only OEM tune & you're right, it feels like a flat spot.

No not yet but will give it a go.

That's not good news - hope if turns out to be something minor. Would suggest taking into the dealer for a warranty check.

Did you get the stage 1 or 2 performance upgrade? been wondering about that upgrade

pcockley · 12-21-2011, 06:26 PM

I saw the price and thought mmmmm NOPE!

Haydrick · 12-21-2011, 06:31 PM

yeah, but how safe are the after market chips? also the thought of having to remove and reinstall every year pre/post servicing sounds like a hassle

pcockley · 12-21-2011, 06:43 PM

Safe? There are 1000's in play around the world with no issues. sure you can remove a piggy (20 minutes) before a service or simply turn it off (1 second). with a flash simply plug in and unflash (20 minutes) all of these for under 1k with more power then the BMW pwr kit

Haydrick · 12-21-2011, 06:47 PM

Someone has to show me one day whats involved. I've seen youtube vids on the installation and it makes me a little nervous.

What about cooling? With the bmw stage 2 upgrade there's an additional fan and radiators I think.

pcockley · 12-21-2011, 06:52 PM

Sure but for the same $$$ you could get a JB4, DP's, meth and upgraded oil cooler.

I guess it all depends on what you want to achieve.

I appreciate the trepidation!!! I was rather nervous the first time, there are many members here who would be willing to show/walk you through the install. Once you have done it you will realise how easy it really is. But the first time you take the socket set to the engine bay can be a little daunting, but not feared :-)

Is quite easy! If I was in Sydney I would show you but I am sure pcock would be more then glad to help you out.

Just get a COBB AP if you are worried about going into the engine bay.

Stuart@BMRAutowerkes · 12-21-2011, 08:42 PM

Btw guys Haydrick is N55 so installing a tune is a little trickier than N54 tunes, (JB N55 is easier than Procede N55 due to the crank sensor or lack thereof) but the tunes are still definitely plug and play and give me good gains (although slightly down on the N54 brethren)

Haydrick, I, as I am sure there are others would be happy to assist just don't ask RaihaX to assist with meth cause he doesn't want anyone else to get meth

Stuart@BMRAutowerkes · 12-21-2011, 10:11 PM

Typo: and give good gains.... Not "give me good gains" as I am not n55, n54 ftw

Which gains are you referring to??

Have you re-dynoed your car or done any tuning to it yet, it should be def putting down more than 227.

I have some LUX arriving soon... let me know if you want one

Long story but I got the stage two supplied & fitted by the stealer at their cost.
Actually, quite happy with the performance gains and maintenance of warranty, drivability, etc......

woosh · 01-06-2012, 07:31 AM

Do you mind telling us what the cost price is that the dealer gave you? i'm tempted by this option! thanks

I don't know what the cost is for PPK. The dealer installed it at their expense as a good will gesture free of charge to me.
I would recommend this upgrade particularly if you don't want to compromise your factory warranty.

Haydrick · 01-08-2012, 05:54 PM

Thats one sweet foc item!!

Stage 2 is $3,500 I think from recollection of a flier I received.
