Customer Question

I own a 2007 XJ Sovereign - with 64,000 on the clock.
I had an intermittent judder last September and my garage had difficulty identifying what was wrong. They
- replaced rear brake discs and pads
- replaced front trailing lower control arms o/s and n/s
- carried out a front & rear wheel alignment
Issue seemed to go away, but not really - it is now back bigtime.
Basically, the car judders when moving and also when stationary.
I have it booked back into the garage next week, but am a little wary.
Any help would be really appreciated

Hi .
Any warning lights on when the engine is running.
When stationary is the buffer present when only in gear or also when in neutral .

Hi Greg,
Thanks for getting back to me.
Answers to your questions:
1. There are no warning lights showing
2. As the car is automatic, most driving is in gear, as I do not generally put it in neutral at lights, etc.
Take it that the judder is present in neutral and when in gear.
I had this problem before and I paid the garage £1,200 + to do the work I stated on my original email. As I have the car booked in for coming Tuesday, any help before then would be good

I was thinking a possible transmission Torque converter issue, why I asked if you had the judder in D or neutral or park, if you have the judder in just D and smooth in P then I would be saying transmission issue .
With it doing this in parked then has to be engine or transmission and nothing to do with wheels brakes or drive line .
Check for transmission malfunction codes.
