Shift lock on my 2009 X7 has been sticking over the past few weeks. Not sure as yet if it's the relay or the locking pin itself. I have prised out the fascia to check the pin I'm not sure if the selector knob can just be pulled up and off or if it's secured some other way. I've given it a bit of a tug but I don't want to pull too hard and break something - how is the knob removed?
 
They all get sticky at some stage. I've been living with mine for 8 years or so.

There is an emergency release procedure in the owners manual if you really get stuck. I have a plastic knife in the centre pocket just for such as occasion. I leave mine in Neutral most of the time unless I think the handbrake needs some Park additional security.

Is the relay clicking every time you put the foot on the brake? Even if they click, they don't always pass on the full voltage to the solenoid I have heard. So you could follow the clicking sound until you find the relay and do some voltage measurements/replace the relay to see if that improves it.

I think it is a major job to replace the whole assembly which is how it is sold as a spare part.

There are other threads on this topic on here.

Here is Citroen's blurb, with some suggested reasons for malfunction

Are you guys sure you are not confusing the symptoms with those brought on by the defective relay . That is a well known common fault overseas, and easily fixed by replacing the 3 pins relay located in the passenger side kick panel.
I changed it on my 2009 X7, easy done.
I'm sure I reported on it in Aussiefrogs at the time.

How does the boot come off with the gearshift head still in place?

If it's the same as the early Series 1 C5 it does just lift up?

You may not need to remove on the X7, in this video it's left in place - looks like a manual car with conventional handbrake but may give some clues. . .

Grab onto the leather surround and lift. The panel it attaches to will unclick from its locating tabs and lift up. You can then lift it higher by allowing the leather boot to go inside out around the shift knob.

Cheers, Ken
 
Before you undo anything else, replace this relay, and your problem will be fixed, guaranteed:bosch.JPG

Chris,
I think yours is a later model isn't it, like 2010 or so? It seems the 2008-2009 are more prone to it. I had a 2009 Tourer, which looked like it was terminal, clicking when touching the brake pedal, but getting near impossible to shift out of Park. 10min to replace the relay, and the gearstick change was like new!

One of the first X7s Phillipe, 2008 and going strong, love it :)
When parked on the driveway a slight slope I sometimes hear a clunk moving from 'park' to reverse but no different to the old series 1 C5. I don't regard it as a symptom of a problem just par for the course parking on the slope - never an issue when parked on level ground.

That video is weird to watch. Speaking Spanish (it seems) so it would be a LHD car but it "looks" like it's RHD. So the video must be in mirror...

Yes, I think that's a different issue to the one discussed above, my C5 I used to do that as well. But the symptoms experienced by chodaboy is an electric issue to do with the release of the Park, when you touch the brake pedal. You can actually hear the contact, but it doesn't fully release the gearstick to move to drive. Definitely the relay knackered.
 
I have the same issue that's just come up on my early X7. I will try to change the relay as harrisson_citroen suggetsed and report back. Hope its just that simple.
I had the same problem with my S Type Jaguar and changed the whole selector.. It was quite easy actually but I think that car did not have a release procedure if you got stuck in park.. and the second hand replacement I bought off fleabay does work but its simply just had the solenoid disabled meaning you can shift it into park whilst the car is moving..
See how we go.
 
Just changed the relay harrisson_citroen suggested and problem fixed!
I was somewhat confused with his attached photos; it is the small rectangular relay shown that is the culprit and not the green relay in the photo. To get to that small relay you need to be a master of contortion, work upside down, remove without trying to break an impossible relay bridge blocking it, have a torch in your mouth, a small flat blade screwdriver releasing all the switch and relay clips and your job's done!
I would hate to see the bill to pay some to do that. I was very careful not to force, break or pull anything that didn't want to give way. Everything went back together as I found it.
It's likely that there is another way to get to that relay that effectively sits behind the fuse box (to the left of the glove box) but I couldn't be bothered researching any more..

Aw, come on, not that hard! Took me about 10minutes.

No there is no otherway:nownow: . Have you changed your cabin filter yet? :roflmao:
 
Too funny harrisson! You know your stuff alright!
Cabin fiter? Err no... Is that in the one usually in the engine bay?
Just changed the one on my Jag.
 
Not having the spine of a cat I think it's an awkward job too, even if simple.

The C5 cabin filter is under the glove box. The rectangular door on the side of the heater/ac unit. Smaller Cits have it accessed from the engine bay.
