Mine judders when setting off in first. If i rev the bollacks off it,like a Sunday driver,it dosen't. Doesn't do it in any other gear. Car has covered 30k Auc warranty runs out soon,should i get it in or just put up with it.Only bothers me when i read this post and realise somethink can be done about it.

Get it in before your warranty runs out as my dealer told me it'd be thousands I'd have paid out should the flywheeland clutch need replacing out of warranty. Ask for an internal inspection of the parts as there is no diagnostic computer sensor which they can refer to in this area, its all mechanical. If they tell you they can update your cars ECU do not accept this, its a quick fix that allows you to rev your way past the problem, not actually deal with it. The ECU upgrade should go had in hand with replacement parts as mine did to prevent any problems with the new parts fitted.

Like I said previously, push them like buggery and don't let up.

A common trait on the 320d.

my previous car being an Alpina D3, hence 320d based sufferee from clutch judder intermittently. previous owner had clutch and flywheel replaced under warranty as did i. only for problem to return, dealer kept saying no fault found, so ended up selling the car as it irritated me so much.

that and the turbo lag (mono turbo) ruined what would have been an otherwise superb car. notable that the revised d3 bi-turbo had an auto option and two turbos to eliminate the lag.

now in a 335d auto, so no such problems.

I'm 1500 miles in through my new clutch and flywheel and I don't know if i'm being over sensitive but I'm sure I can feel the clutch juddering slightly when moving off from cold again......

Not good, will keep an eye on it for sure.

[dcb69]

I have the same problem in my 318d, and there's no solution for the moment.

[MEGA]

Since getting my new clutch/flywheel I now also have this.. typical..

Get your CDV removed. In my case I'm fairly sure this is the cause. I never used to have a CDV before they replaced the clutch.

[SteveF1]

Give it another 1500 miles and you'll know exactly what clutch judders really like.

[JudgeJ]

Hi,

I've got a March 2010 320d (M sport) with 7,500 miles on it....Surprise surprise it has got a clutch that judders too! It's great to know I'm not alone in this.

Living on a hill means when I start off in a morning (going up) the clutch judders no matter how much or little you rev it. The same thing often happens if you try taking off quickly on the flat.

I'm not sure if it's relevant but if you turn off the DTC and start quickly, the problem does not seem to appear.
** Note to self, must try this technique on the hill in the morning....

Have booked car into dealers so let's see what happens.....

[MOB]

Haven't read the full thread, but its also a big issue on the 1 Series - my 118d does it, so does my wifes 120d

[Rob55]

Just to add my tuppence, my 2006 320d is fine but I was riding as a passenger in a 2009 320d touring last week and I noticed very bad clutch judder a few times over the journey, I was sitting in the back seat for a couple of hours and it was extremely noticeable, the whole car vibrated as the guy was taking off in first. It wasn't his driving style, it was definitely something funny about the car itself. I just remember thinking, I wonder why my car doesn't do this (thankfully!)

[Lechiffre]

After 3 months of hassling my dealer (and having the latest software update) my 320 M Sport Coupe is in pieces at the moment awaiting BMW approval to fit new clutch and flywheel.

Don't accept the ECU upgrade it is only a mask for the problem... not a cure

[Teutonicdriver]

My 320d is now one year old with 11000 miles and Ive had this problem intermittently since new.
I think I will give Wingtip/Doughboys "burning in" suggestion a go.

I found an interesting article called Bonanza effect. Maybe you have seen it. It is in german and i have translated it with Google translator. German members could tranlate it better. Maybe this is the part of the problem with our clutch judder.

I also found out that new eco model E90 320d EfficientDynamics with N47 engine (lower power than regular N47) has differnet flywheel and clutch than ordinary E90 320d N47 engine. BMW 320d and 318d with N47 engine have the same flywheel and clutch.

http://de.wikipedia.org/wiki/Bonanza-Effekt

In the Bonanza-effect refers to a rocking of the engine block for diesel vehicles from Mercedes-Benz with manual transmission.

The Bonanza effect is not a technical defect, but an intrinsic phenomenon. The longitudinally mounted engine / transmission unit twists here in the soft engine mount and into the soft flexible disk of the propeller shaft, making periodic acceleration of exchange are created. This soft suspension was and is necessary in order to compared to gasoline engine high vibration of the diesel engines away from the passenger compartment. That mainly Mercedes-Benz is known for this effect is, is because of that Mercedes-Benz until the 1980s, with few exceptions, the only provider of volume vehicles with rear-wheel drive and diesel engines. The rocking occurs mainly after gear changes and load changes, especially in full load operation. It is felt by the occupants as unpleasant, but can be practiced by driving, especially in dealing with the gas and the clutch pedal to avoid.

With automatic transmissions, the problem is not because it is at this through the torque converter no rigid mechanical connection between engine and propeller shaft.

From 1987, when the 5 - and 6-cylinder naturally aspirated diesel from Mercedes-Benz started to tackle the problem through an electronic Antiruckelaufschaltung (short ARA). Here, a control unit monitored by a sensor on starter ring gear of the flywheel, the uniformity of rotation of the crankshaft. Once oscillations occur, the injection quantity of the mechanical injection pump by means of an electromagnet is reduced temporarily. Today, the phenomenon thanks to the electronic engine control systems / schemes disappeared.

Especially among people who are waiting their vehicle itself, there are heated discussions especially on the Internet to help. It is an improvement by the replacement of worn parts (see below) is possible, but a complete disappearance of the judder effect is, as experience has shown virtually impossible. It is also reported from some vehicles of the affected models, which are delivered from the factory at all from Bonanza effect affected.

A possible mitigating Bonanza effect is possible through:

Replacement engine bearings or dampers
Exchange Couplings of the propeller shaft (Hardy-disc)
Replacement or overhaul of injectors
Setting start of delivery
Replacing the Gaszugdämpfers

My car is a month old only 1100 miles and shudders when pulling away especially after a bit of stop start traffic. Totally unacceptable and it isn't my driving as I drive lots of other cars and never have any problems. It's a lease car on a 3 year deal. I am loathed to take it back to the stealer as I don't want the software update people have talked about. Are there any people in essex who can supply and fit the modified CDV ? And does this cure the problem for sure? My car is a 318d LCI 2010 6MT
Any comments would be gratefully received

[vortex1973]

Hi all,
First post so please bear with me. I have a 2010 E90 320d and have had it since last December (coming up to 1yr old). It had its first service a couple of months ago (I'm quite a high miler) and reported the judder as I had it on my old '07 plate 320d (inherited from a previous driver who was not mechanically sympathetic so put it down to abuse).

Was told by the dealer a software fix to adjust the revs is coming out, long story short it went back in for the fix only to be told the fix raises the revs to approx 1400 rpm at idle, this gets round the "driver error" of not giving it enough revs when pulling away, once the fix is on it cannot be removed!

I told the advisor I didn't want it doing as that was a ridiculous fix so I'm back to square 1, I have tried pulling away on tick-over and with up to 2000 rpm on the dial and all more revs do is cause it to shake its arse even harder. Not impressed, BMW UK have been emailed and I'm awaiting a response.

[SteveF1]

As I've stated previously you need to go straight to the top at the dealership. Clearly this issue is inherent in the car as its been doing it ever since the E90 was released and I'm shocked that new examples are still being churned out with the same issue. BMW put it down to a side effect of the dual mass flywheel but this problem should have been erradicated by now, its simply not on.

I guess their thinking is that because your car is so new its hardly likely that the DMF and clutch are mechanically broken so they've gone straight for the electronic mod instead which is easier and much cheaper. The replacement of parts and mod should go hand in hand with each other as the likelihood is that after judder wear between the DMF and clutch the face of the DMF becomes warped making the judder more pronounced and as the DMF fails it leaks oil onto the clutch which renders it useless as its contaminated.

The least BMW should be doing in your case is stripping the DMF and clutch to see if its ok, if it is then run the rev update and see how it goes. At least this way you can be sure the DMF and clutch are ok because if they are not all you will do is run them quickly into the ground making it look more like wear and tear or missue by the driver. If they eventually fail out of warranty BMW will put it down to wear and tear as they will almost certainly do.

Ultimately its a crap fix for a poor mechanical design problem but its the only one they have and aren't likely to do anything about it now with the new 3 series coming out next year. I'm just surprised they don't offer the rev mod out of the box.

Coincidentally I had my DMF and clutch replaced at the beginning of the year along with the software update and generally its been ok since. On hills its still a pain in the ass as it can judder and also at junctions when holding the car against the clutch for prelonged periods of time its near to stalling when you actually find the chance to pull out. Sometimes dangerous but something I've got used to now sadly.

[Wingtip]

Just been back to this thread to check on the latest status following advice to rev the clutch till it smells. Car has now done 65k and has been looked at by BMW on every visit, ie "have a look at the clutch judder". It's been remapped and now idles at 1200 (unless you push the clutch right down to the floor, when it then reverts to around 800) and still suffers from clutch judder when pulling away in 1st on an incline. I like the explanation from the german site. On my frequent thoughts on what can cause this I have wondered about the rough idle of the 4 cylinder diesel engine and the feeling of flexibility in the transmission engagement. There does seem to be a strange effect when the handbrake is applied for a hill start, the car can rock on a couple of inches of play between full forward engagement and rocking back on the brake...I had a Fiat 124 a long time ago which suffered from Clutch Judder (or axle tramp) and the solution to that was a new universal joint in the prop shaft. Anyway, just wanted to advise that the only solution I can recommend is to hold the handbrake on and rev the car so that the clutch slips for about 10 seconds. Take one of those every couple of months to ensure better than average pull-offs in 1st (I appreciate that it helps if its a company car.!) I do hope BMW reads these posts and can fix this problem - I'd like to get a 330 next year but I'd buy something from another German manufacturer if this problem was even slightly detectable in a test drive..

[the_rangdo]

Can any of you more mechanically minded folks try and give me an understanding of how the judder can be erratic depending on the temperature as there seems to be a correlation?

Last week was milder, and the clutch was perfect - could not make it judder at all even if I wanted to. As the weekend turned colder, yesterday the judder was back

I can understand some condensation can form if the car's been stood for a while (I didn't go anywhere over the weekend) but that should burn off once things have warmed up. I have a 40 mile each-way commute, you'd expect condensation to be gone after that but the judder was present all day and with the same 'intensity'.

Today the temps are a bit milder and with overnight rain - practically no judder, only on steep hill starts and even then much less than yesterday.

Booked in for next week anyway to get the thing inspected but just trying to figure out how it can vary so much.

[Archer-s]

Hi Guys

I have got the new 320d EfficientDynamics with the different clutch and still get the judder

but have been told there is a revise part coming out soon, and I am on the waiting list, now dont know if the same clutch/flywheel with be the same for the other cars, but will let you know once I get a call from the dealers,

PS - has anyone else been told about this part?

[DaN_BMWE90]

I guess forums are for more info the better so I may as well add:

I have a 2007 320d pretty new to me, bought from a BM specialist with a warranty.
Anyway, iv been pretty scared that the clutch is just going to give out and its been bothering me, it only does it when its cold? and only in 1st, but sometimes shifting from 2nd to 3rd there's a bit of jump. But its not ALL the time in fact its not everyday? I do treat it gently and as smooth as I can. I guess I can feel slightly better as iv read this thread and am not that alone.

It still plays on my mind, but mark me down as a judder sufferer as well.

[Mr Wolf]

I've just found this forum after looking on google to see if other drivers are having the same problems as me as I'm getting frustrated.

Previously ran a 2007 320D SE Tourer for 3 years and 60k with no problem.

In July 2010 got a new 320D Msport Tourer Business Edition. All ok to start with but clutch judder developed after about 5000 miles and got progressively worse. BMW dealer tried the "software update" as apparently BMW insist they do this. It made no difference.

A few weeks later they took the car back in and, I believe, replaced the clutch and flywheel.

All was great for 3 months (about 3k miles) until last week when the problem returned. The car is now booked in with a different dealer (only because they are closer to the office) so it will be interesting to see what they say.

[the_rangdo]

New bulletin just been issued about the clutch judder, apparently a software update is due which will apparently fix what's been diagnosed as excess vibration through the crankshaft with engine speeds in the range 900-1300rpm.

Update for the N47 (which would be mine ) should be released later this month but it's via Jetstream (i.e. requires dealer server to be updated) rather than a CD, so advice to me is to ring towards the end of April to arrange booking in.

I think other engines are due around the same time too, but don't quote me on that.
