2005 S-Type 3.0 V6

My car has the oft-mentioned power steering shudder in garage/ parking scenarios. It is very slight...but now that I've become aware of it, it is a bit of an itch. The Jaguar TSB for power steering noise often comes up.

The original intent of the TSB was to fix a noise problem. I've read a LOT of prior postings which mention trying the C2S48887 power steering additive for the shudder complaint as well. Problem is, I've yet to find a case where the shudder has been cured with the additive.

If the success rate has truly be zero then I'm not anxious to go thru the additive ritual just for fun, so to speak.

Thoughts? Has anyone fixed the shudder? If so, how?

Or, realistically, should I just shrug it off?

Many thanks
Doug Dwyer

PS- I should mention that the p/s fluid is fresh.

 

Don't know but that additive fixed my old 2005 STR 100%?
Many other have been fixed too?

OK, thanks.

Anyone fix the shudder?
