new owner - couple of questions - E92 335i

[SR20_Guy]

Hey guys,

Recently picked up an '11 model 335i coupe dct. So far I've enjoyed getting to know it, but have a couple of questions I want to verify if some things are "normal".

a) On cold startup in the morning, it seems to only breath through the right tailpiece. Once warm the left tailpiece also opens up. I'm guessing that's normal. However, the left tailpiece makes a little embarrassing rattling noise during this time. Whats up with that?

b) Engine startup also sounds kinda harsh. Nothing major but it just kinda jumps to life with the kind of rattle and shake that you'd expect from a diesel. Hard to describe. Only takes like half a second but I notice it. Almost as if the engine mountings shake. Normal?

c) Front suspension seems a fraction noisy to me at low speed bumps over driveway gate sliders etc. Sway bar end links? Motorplan covers stuff like this?

d) engine is noticably rougher with the a/c on at idle or startup. normal?

e) damn thing runs out of steam waaaay too soon. Sometimes mashing on the accelerator will cause it to gear down to say 4th and revs will jump to say 5k rpm but it just doesn't seam to be "pulling" hard. Could just be that fact that I come from a naturally aspirated platform that I expect more but still. How will I know if it has a boost leak or something?

f) On startup while I wait for the motor to warm up I can hear the ECUs of the car buzzing, stopping, buzzing, stopping etc. Sounds seem to eminate from the dashboard area where the nav screen sits. The same kinda sounds that you get when you unlock the car or close the boot etc. like it's constantly running diagnostics.

g) Can I get software while still in motorplan?


thanks

Hey
I've had my E92 335 for about 8 months now. It sure as hell never felt slow or suffered from much Turbo lag?
The car does seem to run rough on start up until revs drop to about 600rpm. Has a nice throaty sound on cold start. If you aren't finding the car quick, the plugs, injectors and high pressure fuel pump are all problem areas to check out.
I think the sounds you are hearing are probably the electric pumps running? Mine also make those kind of electric sounds.
As for software that is MP approved, not too sure if ACS do it for the 335i, but sure it will be a small fortune. JB4 is the way to go, then remove before servicing? Or direct flash tune, but you always take the risk of motorplan being cancelled if they find out. JB4 or tune R7k ish, ACS about R50k.
Hope you enjoy the car, she really really shouldn't feel slow though. Maybe put it on a dyno and check?
Good luck.

Hey bud

I have also had my 335i DCT e92 for about 3 weeks now
Also start up is similar - so assuming this is normal
It was the same on my 335i e90

I just installed the JB4 software and car is still under MP - Just switch to map 0
when going in for servicing


No issues with power on the car. goes like a beast even before Software

 

[SR20_Guy]

cool thanks for the responses so far.

its not dreadfully slow. Think I just expected more. Previous car was a HR model 350z with minor mods. At this point I feel the z would have the upper hand in a run, especially on the highway. Would still like to verify the bm is at least on par with others though.

Anyone know what std power on the N55 should be on a specific dyno around gauteng I can compare at? or better yet, decent 1/4 mile time for a unprepped track like s2s at night at tarlton?

if you have motorplan and wish to keep your motorplan please remove your tune before going to the dealership... the jb4 when removed will not leave evidence of being tuned however if you leave it in you are only asking for trouble...

SR20 guy...

your cabbie is still on plan... make a list of the problems you have and make it their problem... non of the problems you listed should happen with the these cars...

Its normal, you have an auto i assume. There is a metal flap in the left tail pipe. As the revs drop, this flap opens up, its does rattle against the inside of the tail pipe.

b) Engine startup also sounds kinda harsh. Nothing major but it just kinda jumps to life with the kind of rattle and shake that you'd expect from a diesel. Hard to describe. Only takes like half a second but I notice it. Almost as if the engine mountings shake. Normal? You should have BMW look into this. The car is direct injection though.

c) Front suspension seems a fraction noisy to me at low speed bumps over driveway gate sliders etc. Sway bar end links? Motorplan covers stuff like this? The E90 don't have the strongest suspension have BMW look into this.

d) engine is noticably rougher with the a/c on at idle or startup. normal?
Not to sure on this one. Again have BMW look at it.


e) damn thing runs out of steam waaaay too soon. Sometimes mashing on the accelerator will cause it to gear down to say 4th and revs will jump to say 5k rpm but it just doesn't seam to be "pulling" hard. Could just be that fact that I come from a naturally aspirated platform that I expect more but still. How will I know if it has a boost leak or something?

This could be a few things, boost leak etc. Again use the MP

f) On startup while I wait for the motor to warm up I can hear the ECUs of the car buzzing, stopping, buzzing, stopping etc. Sounds seem to eminate from the dashboard area where the nav screen sits. The same kinda sounds that you get when you unlock the car or close the boot etc. like it's constantly running diagnostics.

I have this noise on my car. But its gone now. Get BMW to check it.

g) Can I get software while still in motorplan?

If you can live without your MP the choice is yours


thanks

:tiptoe: Welcome to the Family Doctor G been waiting for you to pop up please post some pics of your beauty

 

[SR20_Guy]

Great thanks. And thanks for the welcome....

Will get the car to bmw to double check everything. Any specific dealer that does better with these than others? I'm in gauteng. I'm a bit nervous to complain about lack of power, cause that sounds like a good excuse for a service technician to joyride the heck out of the car to verify it.

 

[akash]

Try Bruma Auto in Bedfordview

 

[Sabretooth tiger]

Welcome Ronnie. Glad you joined us.

Take the car in to BMW, as its still on plan. I only use Club motors fountains, yes its in Pretoria, but best dealership when it comes to after sales service. I contact the DP directly.

 

[Dmonic1]

Hey Ron..... congrats bro!!! Now post some pics!!!

A). This is normal, both pipes will be active once warmed up.
B). Always had this when I have my cars both of them.
C D E F - Let Motorplan sort this out...

G) NO!! BMW can detect this and you risk loosing your MP! you can flash the ECU (Excede etc) but must flash back to original when going in for service.. If you go PnP route, you must remove it before service etc..

 

[SR20_Guy]

as requested here is a pic of my car.

Ok so with A) I figured the one pipe warm up is normal, but heck it shouldn't have that little rattle. I'm sure people must look at the car and wonder if it's broken or something on cold starts.

Love the ride bud :clapper:

Hey Bud,

You mention that should you remove the JB, that there is no evidence of it being tuned? Now I am a noob to JB and what it actually does but can BMW not check the normal parameters on your car like boost, max rpm etc and tell if the car has been operating outside these if they really wanted too? I understand that under a service interval condition they won't but if something major breaks they could very check if the car has been tuned right?

Just trying to understand. Thanks in advance,

car is looking sweet Ronnie :clapper:
