Shudders on X3's are pretty common, ours has had it for years now. We replace the transfer case fluid regularly. We have come to accept it as standard. It is usually worse in colder weather. The only thing I would say about the tires is to keep them inflated to spec as shown on the door jamb. It is really important for all four to have the same treadwear and air pressure (this applies to any AWD vehicle though). For it not to be a BMW approved tire I think is rubbish.

Mein Auto: BMW X3
We have a local mechanic here in town who only works on BMWs and Mercedes - he does our work for us after the cars are out of warranty usually. He couldn't believe that the transfer case had to be replaced in my X3 at 85,000 miles. But he did say that the fluid should have been changed by BMW at one of the service intervals and it never was. If you've never had the transfer case fluid changed I would definitely get that done!

Before my transfer case went bad the car wasn't performing poorly at all. I never would have known except every warning light in the car came on!

Evan,
if your 4 tires aren`t the correct size (as indicated in your owner`s manual), same brand and tread you will have in the future a serious deterioration and failure of your transfer case. (believe me you don`t want this to happen)
Regarding the transfer case oil, check it out and see if the color is like coke. If so change it. The shudder problem you have is generally related to a degraded transfer case oil and should be changed every 90.000km. At least this is what happened in my case. I changed the oil and the shuddering practically disappeared.

Be sure, as well to have all your tires that comply with the specifications indicated in your owner`s manual of your vehicle.
My mechanic also diagnosed my 2005 X3 (106,000 miles) with a transfer case problem because of the slight whining noise on deceleration and acceleration. I then took it to the BMW dealer, who came up with the same thing. After reading Martin's post, I asked them to change the transfer fluid (which was supposedly done at 96K) and will get it back today. I will also have the tires checked just to make sure they are in compliance. Although this is my first post, I depend on this forum all the time! Thank you.

Quick report on my issue: I felt a slide jerk in my transmission coming from the back for a few weeks. Usually only after driving about 15mi and at slow speeds in tight turns. I did see my 4x4 light come on once or twice as well, but turning off the car fixed that. I took the car in and the BMW dealer decided to change the fluid in the transfer case. Seems the problem is gone now. I commuted to work and back home and I usually would have a 100% repro after that drive. So seems my transfer case is ok after all.

after living with the dreadful clunk for a bout 5 mos now when I disengage the clutch (not all the time, it's intermittent) and some researching on line (mostly here), I finally took it to the dealer for their expert diagnosis. Also, i've recently developed a knocking noise on top of the engine (cam and vanos area) but that's another topic ( $450 just to open up the valve cover and check cams and vanos)...

anyway, they told me that the clunk is due to the transfer case actuator needing replacement, about $1500 for parts and labor plus new fluid. so , i think i will try to change the fluid first to see if that makes a difference .

I have tryed the reset as well with no change. So my question is what part is more then likely causing the shutter in the transfer cause (assuming its the TC)? I don't have any popping when slowing down or taking off or anything, so I don't think a stretch chain. I was kind of thinking a bearing because it happens only if I put a medium to heavy load on it when taking off? Does that sound about right? Or could it be the clutches in side? I'm asking because I found a company that sells some components for the TC and I'm thinking about taking it apart but I wanted to have the parts available so I have a short down time. Also the TC was replace with a new one under warranty from the last owner at about 66k miles because it had a "leak" which I discovered before buying. so this one has about 60k on it with new fluid at about 40k. I don't have any lights on. Any insight would be appreciated! Thanks.
Hi Evan
I hope you have solved your shudder problems on your X3. I recently bought a X3 2.0d 2007 model and replaced the worn tyres. Immediately I experienced a tremendous shudder when changing gears from 1st to 2nd and 2nd to 3rd at low revs. When revs and speed is increased or when cruising speed is reached no problems are experienced. There was also a humming sound.....much like a worn wheel bearing which is audible most of the time while driving but seems to increase in intensity when slowing down to a halt. I had put on non star rated tyres (non BMW approved) out of ignorance. After a trip to a local BMW garage I was told to replace the tyres for a type and make approved by BMW. Due to the cost of this I approached a neighbour of mine who had a similar BMW and had her tyres put onto my vehicle and went for a drive. To my utter amazement....no further shudder or wheel humming was present. All problems ceased. I have since put on approved tyres to the size specified for my X3 and now love my vehicle. I was seriously thinking of selling until the problem was identified. Now will not part with it until I have had full satisfaction from this vehicle.

Yes .....replaced all 4 tyres to the same manufacturer. Was told that the friction co-efficient of the tyre surface on the road is an important factor and this differs from brand to brand as varying patterns and rubber types can make a difference. I must admit here that when purchased I had Dunlops on the front and Perelli on the rear and no problems were experienced. Can only assume that the friction co-efficient and the run-off is similar (both star rated tyres) for both manufacturers. What could be problematic is that the same manufacturer does not have tyre moulds for the 2 different tyres sizes found on most X3's thus the different brands for front and rear. I have put on 235 50 18 tyres on the front and 255 45 18's on the rear (as per spec). Fortunately Continental make both these size tyres and I therefore have same tyre thread pattern and rubber type for all 4 tyres. I aerated with Nitrogen. Juyst throwing that in for completion sake. Again.....the only jerk in my vehicle now..... is the driver....LOL. Hope this helps somewhat. Tyres are important and worth the cost occurred to change to approved types.
