It can run anywhere from $500-$700. My dealer did mine for free due to all of the other problems my car has had with the fuel system. It took them 5 hours...

Well, my problem is back. 5,000 miles since the repair. Same symptoms, no codes. I will let you all know how it goes. Doing the FI cleaner now. If that doesn't work, I will inspect the intakes. Then back to ths charge air seals. Wish me luck.

Engine Shuddering in 335xi

I'm having the EXACT same issue as originally described in this thread. Hesitation / shuddering at @2,500 rpm in 4th through 6th gears under heavy acceleration. 2008 335xi 6MT, 45,000 miles. The dealer has seen it four times for this issue: performed recall, changed spark plugs / injectors, you name it, it hasn't fixed the issue. After a ride along w/ a service tech a few months ago they observed the problem and changed the injectors / plugs and it helped for a few months but the problem is back.
I'll give the Techron a try and see if that helps. If not, maybe I'll talk to the dealer about the walnut blasting. I purchased the car CPO 18 months ago so maybe the CPO warranty would cover the issue.
Love the forum - this has been helpful as it confirms I'm not crazy and that others have also struggled w/ their dealerships.

Help

I see alot of discussion about the same issue BUT WHAT IS THE ROOT CAUSE AND FIX? You guys posted these issues a while ago so the issue must be fixed now? What was the correct fix?

I have a 2007 BMW 335 and it is doing exactly what you all describe.. sudden jerking in 3rd gear right around 3000 rpm when hard acceleration is taking place. If you depress the accelerator very lightly no issues..


and i have run thru 2 bottle of TECHRON (2 gas fill ups in a row) and still have the issue..

techron will NOT clean the intake valves on a DI engine. the gasoline (and techron) are injected directly into the cylinder, bypassing the valves. the only way to really clean the valves is by mechanically or chemically cleaning the valves from the intake side. this is the walnut blasting that the other posts talk about. you can run techron through a DI engine all day and it will not touch the carbon on the intake valves.

Walnut blasting was the only way to fix mine.

The car would accelerate through that range well enough but it was very annoying. It is particularly noticable in 4th through 6th gear. In 1st through 3rd gear the car accelerated too rapily through the rpm range to notice the roughness unless you are looking for it. My car has had the HPFP and all injectors replaced under recall and I paid for new spark plugs about a year ago and it currently has 67K miles on it. Otherwise the car is great.

I had the car scanned and there is a single code stored, (2AAF, Fuel Pump Plausibility). I took it to the dealer and they confirmed my symptoms (I did not tell them that I knew about the 2AAF and the TSB) and said I need a new low pressure fuel pump, the one in tank. I asked my service advisor if they were sure. "Why is it only in that rpm range?" He said the low pressure fuel pump is variable delivery and at that rpm delivery, that is the issue. I said OK but "fuel delivery at 2500-3000 rpm is different at each gear and varies with load on the engine." He said "we are sure that is the problem. I said "OK, do the repair." By the way, the BMW service bulletin says "do not replace low pressure components for 2AAF without testing a lot of other components first."

I picked up the car after paying my $700 and started driving it home. After warm up, I started accelerating and the car was still doing the exact same thing. I immediately brought the car back. The dealer has had the car seven days now and just told me today that they have opened a PUMA case with BMWNA.

I am reserving my opinion of this dealer until I have the problem resolved. Everyone can make a mistake. I will update the post as soon as I have resolution.

Has anyone experienced the same thing?

Thank you for your post your I'm currently experiencing the same issue on my 2010 135.

1) Fill up with Shell 93 octane or Chevron 93 octane

2) Buy 4 bottles of BMW fuel system cleaner plus (just wait and let me finish)

3) At the first fill up do this: a) put a bottle of fuel system cleaner plus in before filling up the car b) warm up the engine at low RPM and speeds for 20 minutes c) take car onto the interstate and do 70 mph in 3rd gear making sure you are turning at least 4k RPM. d) Do the drive for 30 minutes and then shift to 6th and let the car cool down.

4) Two times a week for the next two-four weeks repeat number three making sure that you are running Shell or Chevron and using a bottle of fuel system cleaner in each tankful until all 4 bottles are gone.

I can almost guarantee your hesitation problems will be gone before or by the time all of the fuel system cleaner plus is used up. Once you have corrected the problem maintain the engine by doing my suggestion once a month. This is how I kept my N54's running good.....

I will give this a shot. I recently had the 5th coil replaced on my 2010 135, the car drove ok for about 3 weeks then it began to hesitate again and threw another code. Thinking that it could have been the same issue as before and being so close together I decided to replace the spark plugs. It drives good now except that it rides a little rough between 2500-4000 rpm on heavy loading.

What happened with your repair?

I was having the 3K rpm hesitation on my 08 335i 6 MT (177K miles)as well. I replaced the charge pipe o ring ($6 from dealership) and all is well now. It must have been losing boost through the o ring.

I had a similar issue to the original post in this thread. While on my way home from work, I saw a newer Mustang take off and gun it from a stop sign on a country road. I thought, 'Well, might as well go chasing!' I left it in regular D for some reason, and accelerated pretty heavily. It was around 3rd or 4th that the engine started hesitating majorly, and the SES light came on (also, my blood pressure spiked). I was not getting much in the way of acceleration, so I pulled off, shut it down, gave it a minute to think about its actions, and started the car back up. No SES light, engine revved fine. I began driving, this time a little more gingerly. I noticed that there was still hesitation between 3-4k rpms. This is not my everyday driver, so I decided to drive it a bit more and see if I could reproduce the symptoms. Then, the other day while getting on the interstate under normal interstate acceleration, I noticed the hesitation. (I should add that the hesitation was minimal to non-existent in sport mode or "manual.")

I came across this thread and decided to use Alpine's suggestions. I have not yet added any fuel system cleaner, as I had just filled my tank. But yesterday I drove to Chicago, so kept the revs around 3500-4000 for 30 miles of the trip up, and then 30 miles of the trip back. I now have zero hesitation under any load.

I presume that since I bought the car 3 months ago from a dealership just outside of the city and it had 41k miles on it, that the car never was able to get up to a temp that would burn out any of the carbon.

In case this fix is only temporary, I've already been shopping for walnut blasters! :o)

Bringing up an old thread because there is a lot of good info in here, and I'd like to thank each of you for contributing!

Other than the electrical fan failure, I'm wondering if the rest of the issues could be related to carbon buildup in the cylinders, or valves, or both. I've got clear misfires happening at times, that go away after warming up, and I notice a severe lack of power between 2500 and 3500 rpm, in what appears to be every gear. I'm going to try some fuel cleaner and see what changes first, but next I'm guessing lpfp.

2007 e90 335i

Here is the list of codes:


Fault: Electric fan failure

Code: 2EFE

Fault: Oil condition sensor communication via BSD interface

Code: 2E9F

Fault: :Map-controlled thermostat / Engine misfire: injection shutdown

Code: 2EF7

Fault: Misfire detection cylinder 3 in 2 Firing order

Code: 29CF

Fault: Misfire cyl. 6

Code: 29D2

Fault: Misfire detection error summation

Code: 29CC

335i Engine Hesitation between 2500 and 3000 rpm

You seem to have a few issues going on. Based upon the mileage, the misfires and the lack of power between 2500-3000 rpm probably is caused by carbon buildup on the valve stems. A walnut blast should help a lot if carbon is the problem.

Can any shop do the walnut blasting? Sounds like it's $700-1k from the dealer, thinking a shop other than the dealer would be less expensive. I was going to start with the fuel system cleaner and hope for the best as that's a much cheaper solution, but it sounds like a blasting would without a doubt increase performance.

No doubt above 3500 rpm the car makes plenty of power, and feels strong(torque) from 1k-2.5k rpm as well, but 2500-3500 there is very little torque.

What are the odds this is a lpfp issue? Would a faulty or failing lpfp still provide good power at higher RPM?

Where in Washington are you? I had my walnut cleaning done by Carl Warren in Portland. Great price and great guy. He is cwarren on e90post.

Mobil 0w-40 causes hesitation and rpm instability

My 2011 335i just hit 52k miles. Since the included maintenance is over I opted for the European blend 0w-40 as many others have. Very soon after the oil change the engine would rev between 500-2000rpm on startup and stalled twice. On the highway with cruise control on, the engine would hesitate- also continually stall and restart. I realized Mobil NO LONGER IS BMW LL-01 APPROVED. I changed to Castrol 0w-30 euro blend and no more above problems. Please be aware of the above! No more Mobil for me.

Seeing fuel doesn't actually pass through the intake system your answer will only solve injector clogging. You still need to have a reputable shop walnut blast your intake ports to clean the carbon build up. 335i are notorious for building up carbon on the valves. Average cost is around $450usd
