I have a Yeti 2WD 110bhp that is 10 months old. It has never been possible to use 5th gear under 40mph because of juddering. To keep at 30mph 4th has to be used. I thought it might be because the engine was a bit tight and it would improve with mileage but it's now done 6000 miles and seems to be getting a bit worse. Now it tends to judder in 5th at 40mph if the engine has to work a bit.

I noticed a big difference in flexibility with the 2.0 CR engine as opposed to the 1.9 TDI in my previous Roomster but again put it down to tightness of the engine.

I'd welcome any observations from any other 110 2WD owners.

I find the engine often juddery(and still stall sometimes at higher speeds), but I am still getting used to having a Diesel as MY car, rather than something for work.

I was taught to change to 4th around 28-32mph and then 5th when cruising, usually towards 40, I try to change when the gear change 'arrow thing' tells me too, but this isn't always the right gear and may have to change again.

I'm making a longer run up to Suffolk tom, so will have my first experience on a longer journey for a while, so will try to reduce my boredom by working out best gear change speeds!!!

What's the RPM at 30mph in 4th? I normally run my BMW320d in 4th at 30mph, in 5th at 40mph, not letting the RPM drop lower than around 1,200.

To be comfortable my 170 tdi has to be in 4th at 30, and 5th at 40.

6th is "juddery" below an indicated 43 mph.

Like it from new. I put it down to backlash in the 4x4 transmission maybe? or thought VW CR diesels not too flexible.

Can you remember the RPM at which the juddering starts, bilun77?

To run smoothly it has to be above about 1200rpm

I have less than 3,000 km on the clock and she is smooth from 1100rpm - around 60kph (37mph) in 6th gear - acceleration is relatively slow until she hits 1500rpm then she flies.

My 140 is uncomfortable below 1200 rpm-I suspect you aren't meant to operate below that.

I have the same 110 cr 2.0 diesel and mine does the same I've done just under 6000 and I've just adapted my driving to accommodate it, I honestly don't even notice it any more, but it did bother me at first.

Good luck with it.

First Yeti a 140 with the older first generation CR engine was noticeable tight when new and it took several thousand miles to overcome having to hold a lower gear for longer.

With the current Monster a 110 but 4x4 and 6 speed then up to 40 mph I use 4th to 60 or just below its 5th after that 6th. She will come down into the mid 40's in sixth and pull away but I sense she's in 'a kind of negative boost' which I don't think for a diesel is a good thing, therefore I try drop back the gears.

With the 5 speed I believe the 5th is quite a long gear so more designed for motorway cruising, so I'm not overly surprised some are experiencing judder at lower speeds; probably need to hold 4th to a speed in the mid to high 40's and maybe more on an incline.

To my way of thinking a 6 speed is more suited to the 2.0TDI CR, however that adds to the weight and increases fuel consumption. So the compromise is a 5 speed with taller top gearing.

I have less than 3,000 km on the clock and she is smooth from 1100rpm - around 60kph (37mph) in 6th gear - acceleration is relatively slow until she hits 1500rpm then she flies.

That's similar to my BMW320d, which has 163hp and over 300Nm torque. In 6th it has 35mph per 1,000rpm and it feels uncomfortable to load the engine below around 1,100rpm; hence my gear/speed ratios of 4th for 30mph, 5th for 40 and 6th thereafter (if appropriate).

I have 110 2WD and it does it occasionally for me but only if it slows to about 35mph. My engine loosened up considerably after 15k miles and now I quite happily drive around in 4th for 30mph and 5th for 40mph (particularly in town with the cruise control on - too many pesky speed cameras).

Interestingly, my wife has a Greenline Fabia and it used to do the same for her. She's now done just under 10k and it will happily drive at 30mph in 4th whereas before it was very juddery.

I reckon you just need to give it chance to loosen up.

Sorry, but am I missing something here? If you're in too high a gear for the roadspeed, engine speed will drop to a point where there is juddering (and if it drops any further the engine will stall). Isn't that true of any engine, in any vehicle? CHANGE GEAR! That's what gears are for!

31k on mine and it judders in 5th at about 43mph, clearly the map is not quite right. Slightly slower or faster and there is no problem, but if the juddering starts the obnly solution is to drop to 4th and change the speed slightly before going back into 5th.

Thanks for all the replies, it seems to be normal from what has been said. My problem seems to be expecting it to behave in a similar fashion to the 1.9tdi Roomster

Bobdog. Putting it like that is obvious but see my comment above, my expectations are at fault not my common sense. YET!

The new CR's are much different to the older PD's. As above. Keeps the revs at around 1,500rpm and it should be happy. Any lower than that and you;re not doing the car much good and certainly not if you accelerate. The clucth won't like that!

Don't just think black and white as in "I'm doing 30mph now so I must be in 4th as that's what I've been told". Feel how the car responds to the gears and dependant on inclines, traffic conditions etc. I often use 4th at 30 on the flat but will leave it in 3rd if going up/down any incline or in traffic.

Sorry, having one of my 'grumpy old man' stroppy moments

Well I did intend trying to work out the best gear change speeds and RPM'S, but as mentioned above it seemed to change all the time, I felt sometimes in exactly the same gear and at same speed both a lack of power and also feeling unlimited power at different times. I am still amazed at my ability to stall, about 3 times today, at more advanced speeds, I blame driving on different roads and being totally lost,

I became one of those sat nav fiends at one point, driving down farm tracks that although technically routes, weren't actually roads, sampled a bit of off roading for the first time and the lack of 4x4 and being still relatively new and not wanting to break it, I did find myself missing my x-trail... Not with MPG though!

I am still amazed at my ability to stall, about 3 times today, at more advanced speeds,

I've found the CR170 amazingly flexible, it will pull from surprisingly low revs in a high gear. However, it's caught me out quite a few times by stalling because I've been lulled into a false sense of what it is capable of and taken it for granted; the margin between pulling and stalling is very narrow.

Yup, I'm one of those SOGs that listen to their mechanicals - just like music to my ears.

Even a lifetime of listening to this stuff, "feeling" the load on the engine, taking notice of external factors etc, still catches me out occasionally.

There must be a set of criteria that dictate shutting the engine off - speed/gear/throttle position etc. I think it best to keep the engine "humming" most of the time, excepting downhill running etc.

Extremes of high revs/light loads - low revs/heavy loads are not what engines like.

Hi Fred, I know exactly how you feel - my wife's Peugeot 807 (46k), which is a 2.2 Diesel will poddle along in 5th or 6th and not judder at all - revs down to almost 1000 rpm. However my Peugeot Partner - 2.0 diesel (76k) will "kangaroo" in 4th or 5th, so it's not our lack of driving skills. Our local garage says it may be down to the diesel you use ( a lot of discussions on here about that!). I have tried several different brands of diesel, and sometimes I think there is an improvement... I find it tends not to happen if I'm on my own, without my wife telling me how to drive :sun:

I'll have to wait till my Yeti arrives to see if I have the same problem - when it arrives...

On the flat my car is happy at 35mph in 5th, wich is about 1100 rpm. Just like Yeti i'm an SOG who listens to the engine. The engine is happiest when you can't hear it, I also tend not to change gear when the Maxidot suggests as it tends to be rather optimistic.

I had the same problem, rpm about 1400 in 4th and 5th, just take foot off gas and the reapply normally sorted it - had the same with a 2ltr deisel Berlingo, said to be a software problem with only the Siemens brain, had it remapped, solved the problem!

Same with my 2wd 110, only i fitted a racetech box, upped the power to 140 problem no longer occurs, and more economical to boot

salut a la sauvage finistere!

My 110 CR also judders at about 40mph in 5th if the road isn't level. But I expect this behaviour from any engine. RPM is then around 1000, just above idle.

My 110 is very flexible (8000 miles now) and even warns me (Maxidot to change down a gear if the engine starts to struggle too much, as well as warning me to change up if the RPM gets mush past 1500 on a level road at a steady speed, which was a nice surprise.

I remember a older guy once saying to me that I should change gear at every 7mph, so by his reckoning I ought to be 5th gear at 28mph, even if I'm climbing a 1:3. He was just taught that way when he learned to drive back in 1764

My Father still tells me ,"Minimum revs,maximum boost."

It seems that was the best way to get the best fuel economy from the Stirlings and Halifaxs he was Flight Engineer on .
