Someone with 535i Xdrive in Toronto? (jerk/hesitation problem)

Hello folks, I'm starting a new thread on this topic - but standing on the shoulders of previous posts (see links below).

I'm seeking feedback from local fellow drivers, as I'm continuing to try and solve this issue with my dealer here in Toronto.

Symptom: at around 7 or 8 kmh (4-5 mph) the car "jolts" or gives a "kick in the pants". I don't think it's a simple gear change issue. I tried it in 1st gear only (placed the gear shift into "manual") and it exhibits the same behavior. It subsides (but does not go away) after 20-25 minutes of driving (long after the car's engine reaches optimal operating temp).
The technician who took it for a test drive claims it's an Xdrive issue - transfer of torque to front wheels and that it's normal. But I'm not yet ready to give up on it yet. The car is fantastic in most other respects and so smooth - this issue really stands out for me.

I am wondering if there are others with 535i Xdrive cars who may be experiencing it OR NOT - and would love to hear from anyone here in Toronto as well. It'll make it a bit easier to figure out how endemic the issue may be - and communicate it back to my dealer (Toronto BMW).

Thanks so much for any feedback - and apologies for starting another thread.

Hey Salter,

Nice to hear you got your ride after such a long wait.

My 550 experienced an 'on & off' type of minor hesitation at lower gears (like 2/3) on the odd times here & there and I took the car in after X'mas to have the dealer checked out. Dealer found no fault & issue on their scanner (also road tested by the shop foreman on a few km test drives) and there is no update to do on the tranny software. Therefore, SA advised me to monitor the situation for a couple of months. I think I will ask for a software update in the Spring 2011 on my summer tires changeover.

Overall, I just finished my break-in period and had been driving the beast very conservatively. Now I am looking forward to let my car show off the power from time to time (in a responsible manner, of course)

The hesitation I experienced was very similar to my old 08 535xi when I first got the car, it was eventually disappeared/fixed with numerous software updates over the course.

I find when I am on-off-on the accelerator, there is hesitation. I think it is due to combination of electric throttle, and gearbox. If I am accelerating smoothly, no hesitation. If I accelerate, back off the throttle for a second, then get back on the throttle, there is a good 1-2 seconds of pause before the car reacts. It is not turbo lag, it is just a dead spot, nothing happens, gears don't change, engine doesn't rev, just nothing! Very annoying. I have had this happen a few times when entering traffic. Pull out across traffic to make a left turn, enter the middle of the road waiting for a gap and slowly accelerating at the same time, then foot off the accelerator for a second, then go when I see a gap. The car just does nothing for 1-2 seconds, then reacts. I have found when I switch to Sport mode from Normal mode, the pause is less noticeable, I think because the gearbox holds the gear longer when I take my foot off the accelerator. I have tested it while driving straight at a constant speed, take my foot off the accelerator for a second, then floor it. It takes a long time for the car to react, but if while driving along I floor it without taking my foot off the accelerator first, the car reacts instantly. Just my feedback about my 2011 535ix in Toronto. I cannot compare this to my last BMW because it had a Manual transmission.

Thanks for the feedback bobblehead. I'm sure you'll (literally) get a KICK out of your 550's monster engine once you let it rip. My car moves nicely with the 3L power-plant, I can only imagine the thrill of having so much additional power.

I did schedule another visit with the dealership - just to have it on record. I do hope that just as you described, it'll go away in the near future. The car is quite fabulous otherwise. I'm up to about 1700km and flipping into Sport mode is fun. This car also provides a healthy dose of luxury and enough electronics to keep a geek happy. This is a delightful toy indeed. How do you like yours? How does it compare to the old 535i?

As you know, it was a sunny day here in T.O. - so I took a couple of photos (my wife calls it "Car Porn"!).

Thanks for the feedback AVIMAX. Sounds like a different issue - but annoying none the less. I can't say I'm noticing the same in my car - I have power almost instantly when I need it - even when in "Normal". Did your dealer acknowledge the problem?

Hi Salter,

Have you done anything else to your car yet ? I mean modification.

550 power & torque are almost the same as my modifed Dinan S2 535xi. The only difference I sensed is the initial hard accerlation is better on the 535xi; otherwise, cannot really tell the difference.

Salter,

Yes, I think maybe a different issue. I have not taken it too the dealer yet, too busy.
Nice photos.

I did look into it. It's tempting to have 40-50 more HP/Torque for as little as 2k. That said, I was debating with myself the point of doing so. If I wanted to get the extra HP, I would have purchased the 550i - which I decided against. I simply did not see the practicality of 400hp (and an imminent danger to my driver's license).

For now it's an academic debate though - Dinan does not seem to have N55 based tuning yet.

i am looking for a solution to the problem of the jerking when taking off . BMW must know about this and it cannot be acceptable. I wonder if they will do a recall. cannot believe they would think a customer would accept a vehicle behaving this way.

I have the same problem with the "on/off/2 second delay/on" hesitation at most speeds.

I went to the BMW dealer, told the gal there I would like to talk to a mechanic. She went to the back, came out a bit later and said the mechanic told her they had numerous people with the issue and that I should schedule an appointment. He told her to tell me they would reprogram it and the hesitation would go away.
I scheduled the appointment, brought the car in, and shortly after the service guy called and said they took the car for a drive and there was absolutely nothing wrong with it. I tried to explain but he was cutting me off and not really listening. I suggested there are many people online that seem to be having this issue and also pointed out the mechanic from their own shop acknowledged the problem. He said he had never heard of or come across this problem and insisted there was nothing wrong. He did say that I could correct the problem by manually shifting the transmission in sport mode. Hmmm!
I explained that I have driven the BMW 6 spd autos and not seen the problem there..perhaps it is an 8 sp tranny issue? drive by wire issue? turbo lag issue?
Does anyone have any thoughts or been able to resolve this problem?

My 535i has a jerk, too, usually the driver, oftentimes a passenger or two.

535xi here.
Got hesitation and jerk issue . mostly engine/ transmission are cold.
Issue practicly 80% goes away as the car warms up.
Town and country BMW in Markham reproduced the issue did some weird adaptation reset readapt procedure that they said takes over 1 hour. Had Absolutely no effect on the problems.
To me it all lioks like theotle and tranny programing issue

I was wanting to get a 535xi, but all these jerk/hesitation issues are scaring me. How prevalent is this? I see no issues with the 550xi and would love to get that just to avoid the issue, but it would bump up the payments to more than what I had in mind.

Is there any way to tell in advance if a 535xi will have the issue? In other words, if I go onto the lot and pick a specific car, can something be done to check if the car will have that issue. Or is the issue not something that will show-up right away on a test drive?


As an aside, I have a 2010 E350 right now and for the first year, it had a jerkign issue when you first drove the car, then it went away. After my 1 year service, the problem is completely gone. They must have updated some software to fix it.

But the hesitation issue (like in the BMW) still exists. Very dangerous when trying to make a quick left at a light, or pulling out into traffic. The car drives, but even though you floor the gas pedal, it acts as if you are just feathering it.

All these manufacturers need to improve their "drive by wire" systems before they are ready for primtime.

the 'jerk' goes away when my car is warmed up.
The throttle is very sensitive, lead foots will have a problem with this.

I have 2011 550xi, no hesitation issue at all.

For the 535, some bloggers claimed the tranny is learning the driver's input at the first 1000km or so (adaptive drive), since you are not supposed to floor the car during the break in period, thus the tranny may be thinking/learning your accerlation charactistics. Maybe a myth or simply software issue ... nobody knows.

Here is the latest on the software fix ....

SIB 12 09 11 You have to be specific about what the problem is so the SA will write the RO correctly. When the tech reads it he will search and find the SIB.

Problem: Delayed throttle response when driving off.
