Greetings all. I have a couple of interesting issues that seem to be related as it has happend twice now. My steering has gone to a heavier effort, and dynamic mode is not available. I've owned the car for a year now and about a month after purchasing it the dynamic mode went unavailable and I noticed the heavier steering. Oddly, I like the heavier effort as it seems to have far more feedback compared to the normal and dynamic modes so I haven't worried about it, but I like the dynamic mode throttle response and stiffer shocks on the freeway, so I'd really like it to work. The car went to the mechanic for a couple of months (chasing a fuel gremlin which ended up being jumped pump cam timing). When we got it back dynamic mode was back and so was the lighter normal steering. Now, here about 6 weeks later, we're back to heavier steering effort and no dynamic mode. I have seen a TSB for the F-type where these exact issues were associated with the need for an added ground wire, but have found nothing for an XJ. Being that much is shared between the platforms I was curious if anyone had run into a similar issue, and if resolved, what the problem was. FYI yes, the battery is new and charged and the monitor appropriately reset, and no, I don't see any codes related to such things. Thank you much in advance for any real solutions.

 

Are you using SDD to check for codes?

I am. Purchased a scanner with the JLR software installed. When I get some time this weekend I intend to rescan and look at the specific data as opposed to just doing a general scan. Thinking that may show me something the simple scan for codes has not.

 

That's not SDD?
SDD is from Jaguar and it's not an after market scanner.

What brand is it?

JHendo,

What year and engine?

At idle, and parked, does the RPM dip if you apply a large steering input? (Car must be warmed up for this test).

So interesting development... Problem found and resolved. I was under the car today to do sway bar bushings and end links, and find a connector hanging loose in my face. Turns out it came from the steering rack. Snapped it back into place, and VOILA! Steering is normal, dynamic mode is back.

 

Can't ask for a better repair than that!
Good job!
