When I accelerate or start driving up an incline or slight hill on the open road, the vehicle shudders and vibrates. The engine seems to be running fine. One repair shop I took it to said it is the injector and all need to be replaced but cant guarantee that it is the problem. Wanted a lot of money to "experiment" on vehicle. Another repair shop said it was in the gear box somewhere but will never cause damage or get worse. If the vehicle was supposed to run like this it would have from new. It definitely is not right. When I had a Land Rover Defender and mileage was also around same km's it did a similar thing and it was the "spline" (may be the wrong word or description, sorry but I am not a mechanic) from the drive shaft into the rear differential that needed replacing (very low cost) and it was like new. This is front wheel drive though and I have not got a clue where to start looking. I do not trust agents as at 105,000 kms I noticed water in the oil and I was told by the VW agent to replace my motor! At a higher cost than I bought the vehicle from them as a demo model. A mechanic in a small private repair shop did not even look at the vehicle and told me that the water pump was leaking water on the bearing and into the sump. It cost me $3,000.00 to fix it. Has run up to now with no water leaks. So there, do not believe your agents they love money and cannot repair anything, can only guess and charge a you a fortune. If anybody can assist I would appreciate it.

I have seen this in many vehicles myself and nine times out of ten its just a matter of a tune up. This can include the coil packs on top of each plug. Now just because you have to replace one does not mean you have to replace all of them. There is a way to look into the computer data and see if there are intermittent misfires. I would not be afraid to tell you to do the service now if it has been 75,000 to 100,000 miles since it was last done.

Thank you for the information and suggestions. The vehicle has been serviced regularly and at the last service (1,000 km ago) the only problem that showed up on the computer was to reset the turbo. After returning the vehicle to the repair shop I was told to "perhaps " replace the injectors, all of them. I do not like to be used as an experiment at my huge cost and the vehicle is still not any better. The agent merely wants to replace the gearbox which I cannot think is the problem as the problem is not continual. It is probably a simple fault that is doing this as it only shudders when I accelerate or put the engine under slight "load" when going up a slight hill. Once up to speed and the road being fairly flat, the vehicle drives like a dream and very smoothly.

Perhaps "shudder" is an incorrect explanation, the vehicle "vibrates" and shakes badly but the motor sounds fine. Could it be injectors in that the engine is being starved of fuel? Is that why you suggested to check coil packs?

If you have a turbo code then you may be able to take the intake tube off of the turbo and check the impeller for in and out and up and down play and oil/dirt inside. Any tiny amount of any of these might indicate turbo wear causing the conditions you describe.

I have had a new turbo installed approximately 10,000 km back so this is quite new. Do you think CV's could have anything to do with this situation with it being a four wheel drive vehicle?

Absolutely if it only vibrates in motion. Still if you have got a turbo code there may be a problem with the waste-gate or variable intake. Also, check for tires with knobs on them or missing wheel weights. You could go and have your tires balanced just to eliminate that if you are so inclined. Give them a good look see with a flashlight across the tread looking for bubbles. Also wobbly CV axles often have busted boots. Shine your light under there. They will have thrown grease everywhere if they are busted.

This sounds like a driveshaft problem like the center support or flex joint is out allowing the driveshaft to move around causing the vibration.

Here are diagrams to help you see what I am talking about.

Check out the diagrams (below).

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
