The SchnellWagon - E91 335i

Recommended Posts

Picked this up from Hamilton the other day, and it's great to be back in a BMW again.

IMG_2244.jpg?w=1280&ssl=1

Obviously its a pre-LCI 2006 E91 335i with Motorsport spec. So fast, so comfortable and so damn nice to drive. Im smitten!

She isn't exactly stock,

Externally it’s mostly stock, with just aftermarket grilles on the front, tinted reverse lights, carbon wrap on the rear bumper and painted exhaust tips. Under the hood, it’s a bit more special….

Its had fitted,
Rob Beck 2″ silicone intake pipes
3″ catless downpipes
AMS intercooler
BMS catch can
Uprated low pressure fuel pump
MHD OTS Stage 2+ tune
xHP Stage 3 transmission flash
Quaife ATB mechanical LSD

It also came with some extra parts, like a pair of K&N pod filters and fitting kit, and a charge pipe with a blow off valve on it. I’ll be playing with these later.

Heaps of common issues have been sorted, including a pair of brand new turbos, new injectors, new coils, new HPFP,  and various other bits.

Needless to say it pulls like a damn freight train, and will overcome the traction control if you aren’t careful. The LSD makes the rear just push hard, and if it does get a bit lairy its a nice progressive slip. Previous owner claims about 380hp ATW, and the car has done high 12s on the 1/4 Mile.

The other side to it though, is that it’s a nice, quiet and comfortable cruiser. It’s a pleasure to drive around in, knowing that if you have to whip past someone, all you need to do is give that pedal a push. Love the cruise control with braking too, just a shame it doesn’t have the full “active” cruise control, although it can be retrofitted.

There probably won’t be too many updates on this car, as I intend for it just to be a nice regular driver, taking it on trips and things.

LSD is such a massive benefit on these. That alone would've sold me on the car. Great buy👍

Great looking wagon.  I am very smitten with my e92 n54 and it’s completely stock. Yours must be a blast!

Its stupid fast really. I need to buy MHD so i can tweak the map options and turn on the power/boost by gear function, and limit power in first gear. Sucks MHD is both vin and account locked, so cant be transferred.

needs some better offset/wider wheels especially in the rear!

(take my 2p BBS RS-GT :))

I'd say it's pretty damn ideal to get one with those mods and new turbos + HPFP ect. A good buy for sure!

One thing that has bothered me since getting the car was that the transmission always shifted harshly and a bit weird. I put this down to either the trans needing to be serviced, or the xHP Stage 3 tune (I have no "stock" benchmark). Today i tried something that is a bit controversial online; the trans (or throttle) adaptions reset.

Get in, engine off. Turn ignition to ON (idiot lights on), and press the throttle to the floor for 30 seconds. Release throttle, Switch off ignition completely. Now start the car and it should be reset.

After doing this, the trans is behaving a hell of a lot better. D mode is now smooth (had some noticeable "issues" before, that could be easily replicated), and Sport mode isnt jerky anymore. I need to drive the car a few more times, but im almost positive its well improved.

I think in rare cases the adaptations can be out of whack if the car was taken out of normal use for an extended time, maybe if the car was stored or at a dealer for a long time without being driven properly? My DCT was strange when I first got it, it had just been shipped from japan when I bought it, a DME update sorted it but they may have done an adaptation reset. My boss had a similar experience with a 235i auto. 


Some people probably just resort to it unnecessarily which might do more harm than good. The adaptations are for adapting to wear, there isn't some mystical driver behaviour based learning as people, that's some silly rumour that some people persist on spreading on BMW boards. So resetting that when it isn't necessary could make the transmission perform badly until it re-adapts. 

I've seen that the XHP software can actually show you the adaptation values. The XHP dev refuses to add adaptation reset as a feature to the app because he thinks people will use it unnecessarily.

I need to get the xHP and MHD software and see what i can do.

Im not sure the recent use of the car, but it was a second car recently due to him having a replacement already, so maybe its possible it sat for a bit, but when it was driven he drove it hard. I know for sure some other cars/autos learn driving behaviour, and was under the impression BMW did this too, but maybe it is a myth, who knows.

I did read there is a way in INPA to properly reset the adaptions for the trans, but is only meant to be used after a trans service or when the fluid level changes, but people early on were playing with it and cocking things up, so no wonder they dont want to add it to xHP.

You can transfer XHP/MHD licenses from the previous owner if you contact their support

Sweet so its setup to run ethanol maps :D, you'll realize how "slow"the 98 maps feel

It is, and the previous owner has had a play with an E60 blend in the past, but we dont have ethanol on tap down here, so 98 is fine for me (even then, im on a 95 map currently, to be safe)

Will contact MHD and XHP, would really like the licenses for this car

Have emailed MHD and xHP. Im not holding my breath that they will transfer a license, but at least if one can, i only have to pay for the other. There are a few things i really want to change on both, like Linear throttle, and even changing the tunes from stage2+ (which i think is just too much power for the street) or TCU Stage 3 (which is too harsh for the street) to something less.

Im finding the car quite hard to drive smoothly from a stop or low speed when there is anything resembling boost, as the trans just goes into smashing gears mode, and the power comes on like a freight train and gets pretty hairy. The dead feeling throttle pedal doesnt help either. Its easy to crawl away slowly in D, but if you have it in sport mode and try to take off nicely its kinda all or nothing. I could almost live with driving mostly in Sport mode, if the trans was just a bit softer at low-mid throttle, and the rev matching wasnt so jerky when slowing down. Its very aggressive. We'll see what happens.

In the mean time, I installed the DCI that came with the car. Now i have whooshy noises and chooooos when i let off throttle.

Well thats that, both xHP and MHD have come back with the generic "this is what our manuals say, so no, you cant transfer licenses". Not sure I want to spend the money to see if it fixes what i dont like about the car, or not.

Did a drain and fill on the trans today. I suspect that its probably never been done (in 159,000km) looking at the state of the "lifetime" fluid that came out.

Already driving much better. The trans has always been a sore point for me since getting the car as its shifted really rubbish, but its getting better the more I drive it. I also have a new pan/filter, bolts and a couple of seal things on the way to see if it will help even further. Todays drain and fill was just to help clean out the old fluid, so ill drop and replace that when the parts arrive.

Looks pretty typical but you picked a good time to do it anyway

that's how we did the XF 6 speed in my e60, drain and fill, drive for a week or two, then do the dry fill/filter change/mechatronics sleeve etc.  Made plenty of difference.

Enjoying your project journey, Kelvin!

Your original post about it is what made me decide to do it in two steps, instead of just dropping the pan straight away, so, thanks!

Well, it didnt even last a month before shitting the bed. Hesitates when cold with a rough idle, and if you hit boost it deactivates a cylinder and logs a code (29DC - DME: Cylinder Injection Cutout and a shadow code for 2AAF - DME: Fuel Pump, Plausibility). Suspect HPFP.

#N54FTW

Edit: Actually, looking at logs, it could be my LPFP failing. Seeing as low as 30psi under boost, and its strangling the HPFP. Will swap it back to the stock one tomorrow and see what happens.
