Help diagnosing random intermittent juddering and dealer has no idea what's causing it

[ColyM]

Hi, has anyone found a cure for this juddering? I'm getting the judder when trti g to maintain a speed between 60 - 70mph on the motorway. Car is a 2014 1.5 dci Tekna which I've had since new. Well looked after and fully serviced. Feel we can't find the fault, but has experienced it. Turbo, battery, alternator all replaced, but no codes or warning lights displayed. Still getting the judder and fuel consumption is noticeably down
If any one has had a fix to this I'd appreciate an update .

We ended up selling our car, but it did look like it had something to do with the gearbox. Re-oiling it helped. But I'm not sure if it sounds like the same fault as yours, as ours wasn't at high speeds, but when accelerating in the 1500 rpm range. Ours was an automatic.

I am also experiencing exactly this. Seems more common on longer motorway journeys. Feels like the engine is mis firing.

Has anyone got to the bottom of this?

The dealer dealings should be that they verify the fault(s) you report. Meaning that they must repeat it in order to progress diagnostics. Error codes are not enough. Nissan diagnostics uses flow charts to guide "experts" within fault identification procedure and so verify the Customers complaint.

You appear to report here that the engine is trying to cut or is misfiring...which is it? Conditions of occurrence seem to be variable over speed/rev range?

If this is closing toward the "too difficult file", you will need to document it . When, where and how etc and to which a specialist (dealer?) must correspondingly answer.
