[330ed]

2016 330e with 116K miles.

Very harsh judder through the car under the following conditions:

- Car is in ICE mode
- Acceleration under load between 1500 - 2000 rpm
- Most prevalent in 6th gear
- Happens in both manual and automatic mode
- Most noticeable in sport mode but does happen in comfort and eco pro also

When does it not happen?
- Under gentle acceleration even in 6th gear
- When car is in EV mode - no gearbox engagement
- Above 2000 rpm the judder seems to go away


Any ideas what this could be?

Has the gearbox oil ever been changed ?

BMW don't usually do it (though they will if pushed) but I believe ZF recommend a gearbox oil/filter change every 75k or so.

I just checked the service history, it was looked after by Cooper Colchester all it's life, I only purchased the car myself 2 months ago from a local dealer. I can't find any evidence in the documentation I received but I will ring Colchester to confirm.

The oil is definitely a good place to start. The only thing thing that's making me believe it's something else is the very specific circumstances the problem occurs in, but not discounting you could be right.

Had the gearbox adaptations checked today on ISTA+ software and clutch C, E and KO seem to outside the normal range. For reference I was told anything under 100 was normal.

Current adaptation values of the automatic transmission:

Clutch fill pressures:

Clutch A: - 24.0mbar
Clutch B: -18.0mbar
Clutch C: -256.0 mbar
Clutch D: -34.0 mbar
Clutch E: -241.0mbar
Clutch K0: 132.0 mbar
Clutch IAE: 0.0

Had the adaptations reset but the problem did not go away.

This issue clearly needs more investigation but from here logically thinking:

1. Change the gearbox oil, checking:
i. Pan check for metal. If all good
ii. Mechatronic and solenoid. Replace if needed, if that fails
2. Drop gearbox and send for full re-conditioning.


Can anyone else offer other suggestions?

I'm and now experiencing the exact same issue with juddering under load, especially when the car if fully warm, ie after 30min.

Has anyone found a resolution to this, or changed parts/ started any repairs. such as changing the auto box fluids and filters. dealers have been zero help.



same as this thread, that i've also requested support in:

I have seen posts somewhere which describe some F30s suffering from engine vibration hitting the resonant frequency for some of the pipework in the engine compartment, specifically the corrugated air intake pipe from the front to the air filter and/or the air conditioning pipes from the pump to the bulkhead. There is actually a BMW part that is essentially a weight that is fixed to the aircon pipes to stop them shaking. It was described as a buzzing vibration that appeared in the rev range you mention when the engine was under load. May not the same but you never know.

I think my car is actually suffering with this exact issue, which is different to OP, where the car itself is juddering.

Would you be able to link me to any threads which talk about the resonance?

Scanned my car with Bimmerlink for errors and the following came up:

801386

Which seems to relate to this tsb although for an X5
https://static.nhtsa.gov/odi/tsbs/20...63030-9999.pdf

E71459
Signal (torque limitation for crankshaft of air conditioning compressor, 0x1B9) invalid, transmitter DME/DDE

These relate to the heating/air conditioning. I didn't think much of this at first but after reading both threads about resonant frequencies I wondering if it could be related. The level of vibration seems to be a lot more extreme in our case though.

My car has had the Gearbox rebuilt, flywheel changes, mounts and dampers checked etc and still has the problem.

I'm grabbing at straws trying to find a solution at this stage

Hi!

Anybody figured out yet the juddering problem? Im having the same issue with my 330e. Got error codes from trans switching from 7th to 8th gear, after that plenty of other codes from electric motor etc. But the first one was from trans, it did the juddering now and then before this.

[jim salter]

Another bump on this thread.

have experienced similar issues

Received the error:
Driving stabilisation - continue journey at a moderate speed. Have the problem checked by your Service provider.

Had my indy mechanic check the codes & the er was 27 - only 1 permanent to do with the butterfly valve on the exhaust.

[jim salter]

Cleared codes, ran a bit, still got the butterfly valve code.

Have been reading other threads about this and indications are the gearbox and/or mechatronics.

Anyone got any other ideas?

[umbalakada]

Literally same issue! 16 330e with 102K Miles.

when fully heated up the the car shudders in low rpms.
I did buy it from someone i know with the problem being addressed before hand. He apparently diagnosed it by a independent Bmw specialist and he stated that the rear oxygen sensor needs to be replaced?

can anyone confirm? no warning codes. I didn't want to waste £300 if it wasn't the issue for sure.
