Just the other day I was driving my 2010 XK and got the warning light "adaptive dynamics fault" and felt the car firm up clearly driving hard.

Luckily I have a verily good OBD2 code reader and it pointed to the rear right ride height sensor as being the problem.

So I have a couple of questions for those here more knowledgeable than me.

1. What is the part number of the sensor?

2. Is there a good aftermarket alternative to buying Jag OEM?

3. Does the car need to be calibrated after putting in the new sensor or can I just put a new one in and be good to go?

 

Any help would be greatly appreciated here guys and gals.

 

Hsve you read the Service Manual? If not, it's in the Stickies at the top of this Forum.

 

I did thank you

Do see there is a calibration procedure so that answers that.

Sadly don't see an included part number.

 

Greetings @rgfb62 ,
correct, parts numbers are found in the parts catalog.
Of course different cars reflected by different VINs may have a requirement of unique parts. Some dealers provide the parts catalog online.

 

Hi rgfb62,

I'm in the UK and we're experiencing some unusually hot weather at the moment (30 degree centigrade). I have a 2010 XKR and, yesterday, out of the blue it exhibited the same symptoms as yourself. I have a hand-held
diagnostic reader (icarsoft) and that showed right rear ride height sensor. I deleted the code (C1A06) but every time I restarted the car it came back So, it looked like I was going to be looking for a new sensor. However, having deleted the code for the fourth time I then disconnected the battery overnight. When I re-connected it the next morning there was no warning and the functions all work as normal. I'm wondering whether this hot weather may have someting to do with the symptom ?? Before you go out and but a sensor (I believe they're around £130 GBP ($175) from the main dealers I may be worth trying the same as me ?? Good luck - keep us updated.

 

Will do as I live in south Texas so it gets quite hot here as well. Thanks for the help.

 

Though it may seem unrelated, a few of us have learned: check battery first. perform reset. check for codes a 2nd time.
cheers

 

I did check the battery first. Seems to be fine and fully charged.

Just tried what CaptainQ suggested so will leave the battery unhooked overnight and let you guys know the result tomorrow.

Thanks for everything all of you.

 

Just a final update on this. I tried the trick mentioned it didn't work so I ordered the part# c2p15221 and installed it. XK is back to normal function and working great!
