Hi,
First time posting on a forum, so excuse any ignorance. I have recently put a 2008 x type 2.2 diesel estate back on the road after about a year off the road. The thing is, it has a terrible judder / shake when accelerating and also a clunk when changing gear. Im not sure if the 2 are related, but kinda hope it's the same issue. Just wondering if anyone has had anything similar or might know what it is?
cheers in advance.

 

Teddy, welcome to the Fourms. Lots of good info here. Please stop by the New Member section and tell us a little bit about yourself and your car. We pride ourselves in being a better car club and as part of this, we like to get to know one another. This will also give you a chance to meet those that make this place what it is.

As for our clunk/judder, I would first start out with making sure you have adequate fluid level. After that, it would be a good idea to get the fluid changed. Especially with the car sitting for a year, the fluid can get water in it and because of the different hydrodynamic properties of the tranny fluid and water, that can raise some interesting issues. If you do a search around the forums, there are lots of write ups on how to do the fluid change yourself.

Is it al gears or just a single gear? If it is all gears, then most likely it is either a fluid issue or the pressure controller is stuck. If you are having an issue wiht a single or 2 gears, then most likely looking at a solenoid that is being fussy.

 

Teddy9832,

I see in your profile your 2.2 diesel is a manual transmission.
Clunking when changing gear could be a symptom of a failed engine mount or the 'dogbone' stabilizer under the car. (underside rear of gearbox reaching back to the chassis connection point).
When you are changing gear the motor is moving from loaded to unloaded back to leaded again, so the engine is trying to tilt back and forth depending on torque being delivered or absorbed.

In my experience, manual cars that have sat for extended periods can exhibit some clutch plate oddities initially until they have driven out any acquired moisture from the lining material with use again, but I assume you have drive the car a bit since introducing it back into service.

The juddering and shaking while accelerating sounds like something else altogether, but possibly you might start looking at the condition of your ERG valve assembly as they appear to commonly choke up causing rough running.

Do you have any error codes that you can add into the conversation, they might help to narrow down some possibilities.

 

Hi, thanks for your advice. I don't have any fault codes when I connect my reader, but I do have a flashing glow plug light that comes and goes as well as putting it into limp mode when that light comes on. I have seen some threads about cleaning the turbo which may help that, so that is today's plan of action as well as fluid changes and filters. The judder is a he'll of a shake and really bad around 60mph, so I'm thinking maybe a drive shaft as it goes away when the clutch is in or not accelerating? 🤷🏻‍♂️

 

That sounds odd.......I suppose a drive shaft could cause that., but seems you would probably have CV clicking or other noticeable issues if something was that awry with the shaft.
Any perception as to which side of car is shuddering?
I assume you are also getting some pretty significant feedback through the steering at 60mph?
If you can bare doing a quick road test....might I suggest you get the car up to speed where the effect is present and then while still applying some accelerator to maintain speed...lightly press on your brake pedal to just introduce some disc drag into the equation.
Does the effect lessen or disappear? If so it is likely not the drive shafts.
If it does make a difference, if you then just apply a bit of handbrake drag only to see if it is front or rear drag dependent.
In my humble opinion I would suggest you might take a look at front suspension bushings to see if you have some physical drift that might be occurring between loading and unloading of torque into that particular wheel suspension setup.

 

I had something similar with my old Peugeot and it was a worn engine mount, it was the lower one under the engine and closest to the cabin floor. It was like the engine rotated back and forth when accelerating or decelerating.
This should be pretty easy to check by just going under the car and seeing the condition of the mounts. If there's chunks missing or rubber cracked and/or missing, and they look bad, then they're bad.
