Well I just recently purchased a 2011 335d with 10k. In two months I put on 5k. After the first month or so I thought I may have a turbo problem when the car drove lethargically after warming up. It felt more like a 328i instead of a 335d. So just today I took it to the SA at my local dealership. They took the car in for an hour and came back and told me they tested it and felt the lethargic acceleration but they claim it wasn't the turbo but instead the transmission wasn't shifting correctly and so they recalibrated the transmission and updated all the software. Apparently there was an update for the transmission software. Anyway I haven't really had a chance to test the car to see if there's a difference but I was wondering if anyone else has had a similar issue that turned out to be transmission related?

BTW this is my first post on here.

sounds like the egr issue, go to the dealer ASAP!!!

Welcome aboard Merv. I am fairly new myself. As for the tranny issue, I haven't had much experience with this, but will ask if anything has been done to the trans when I take it in for it's next service.

How would know if my car hasn't had the EGR recall done? Is the EGR something that gets replaced with the recent recall?

I've just had the car less than 2 months and haven't received any notice from BMW and the dealership I bought it from wasn't sure of any recall for the emissions system.

Thanks for the welcome! Yes, please keep me posted. I'm wondering if the update for the transmission is just a universal thing they do when your car comes in for service. Mine wasn't due for any service yet and I just brought it in cos it felt like there was a loss of acceleration. I'll be out on the open highway later today and I'll see if I notice any difference in how it performs with the transmission update. If the transmission wasn't the reason for the loss of power and the problem persists, I'll take it back and let them try and find out exactly whats causing the loss of power.

Welcome aboard.

Btw not all 335ds needs the EGR replaced. I talked to BMW NA and most of the 335d made after 6/2011 already have updated version. I got wrong notice in the mail and went to the dealer for the recall. Somehow the notice I got was for 335d 2009 that I never purchased.

[Merv]

Thanks!

Huh, that's odd you got the wrong letter. Well mines a 4/2011 production so I'm guessing it may need the recall done if it got the affected parts installed. Is there a way for BMW to check if my car needs it done via the VIN and just calling in?

I'm wondering if the EGR or other related emission equipment would have an affect on boost performance?

any dealer should be able to check. They can enter your VIN and will tell them if there is open recall. If there is not, they will not replace anything without the car having problems.

Thanks! I'll call tomorrow and see if I need the recall.

I just now tested the car out on the interstate and the boost still seems to be quite lethargic. I'm coming from a 328i and it feels like I'm still driving a 328i instead of a 335d. When the engine has just started up after sitting for a while and I drive it for less than 10 min it feels like the boost is there. It's just usually when the engine is warm that I feel the loss of power.

Heat soak perhaps? My car always feels a little lethargic in city driving this time of year (high heat and humidity).

[Puerto Rican 335d]

@Merv my car was a 06/2011 and had the EGR replaced, I believe the later 07 and up build dates had the new version performed, but yes!! mines had the EGR replaced!!

I called and checked with my SA and there isn't any recall out for mine. So I guess my EGR is an updated part. Did you notice any improvements after yours was replaced?

@Socom What is heat soak? I've never heard the term before. Is it something that can be helped?

[Puerto Rican 335d]

Heat soak is when the IC temps are higher than expected and the IC sensor tells the ECU to go in Safe Mode, that usually happens either when you back to back racing or in Traffic jams or heavy city driving . The only solution is either deal with it or buy a better IC. Anyone correct me on this ok

Ok, that makes sense about the IC and heat soak phenomenon. I'm sure my problem isn't related to heat soak though, as the car drives fine, it's just when you want torque it's not there. The car feels like the boost is there from time to time yet on most occasions it just feels like the low end boost isn't giving any output. I haven't noticed any difference in performance with the transmission update the dealership did the other day. I asked the SA if he's ever had a 335d come in for poor turbo performance and he said he's never heard of a problem like that. There's no error codes or check engine lights. The only way to notice it is to drive it. I may have to take it back to have them spend more time with it to get to find out what exactly is going on, because a small transmission calibration didn't seem to do anything noticeable.

[Puerto Rican 335d]

you have two choices for ICs either go thru Cx Racing(which has one developed for DIESELS) or wait for the WAGNER IC(BTW is in the makings)which will look as OEM as possible, turboeddie from the Boost told me he's getting anywhere from 45-47 mpg HWY!!! yes you read that right!!! from the Cx Racing IC he made

[Merv]

I looked under the hood and on the side of the engine near the exhaust there is a lot of this sooty residue that somewhat wipes off and feels gritty and slightly oily. I've researched forums and it seems this is somewhat normal. I've never noticed this before and everything was clean when I got the car. It's almost like the sooty residue has been sprayed on. I found a post on a mini forum where a guy had to have his turbo replaced including seals by the cat converter. Here's the link: http://www.mini2.com/forum/mini-cooper-diesel/190431-resolved-black-soot-turbocharger-photos.html

I'm wondering if my loss in power may be connected to this sooty residue. This guy here posted pics of his sooty residue. http://www.e90post.com/forums/showthread.php?t=678401

You should get a SES light if you have a boost leak. The soot is normal for the diesel.

How are you driving? Do you have a tune? Are you using cheapo diesel?

Everything is stock and no check engine lights. I've only filled up at Exxon and mostly off the interstate. One time though, I filled up at an Exxon in town and the diesel fuel pump never clicked off when the tank was full and the car overfilled and by the time I noticed my tank had been filled to 16.3 gallons and there was a lot of diesel that spilled out on the ground. Do you think over filling it that one time may have something to do with the recent soot I've noticed?

I still think it's high ambient temps. See what happens when you get some cool mornings. .

[Merv]

It still still feels some what sluggish with early morning temps in the low 70's. The boost coming and going is intermittent.

I've never noticed a regen cycle and I've been driving the car for 5k miles. Is this something that should be noticed, at least from time to time? I drive 75% of the time on the interstate between 70-80mph and the rest is in city and on county roads.

Merv you have serious problem our "D"s are not supposed to be acting like the one you have, take it to the dealer ASAP!! something has to be wrong here
