The parking brake always activated automatically on the 05 VDP...does it not activate automatically on the newer XJ's, XK's, and XF's?

 

It doesn't seem to activate on my '07 XKR either.

 

The parking brake on my '09 XKR does not set itself automatically. To set the parking brake, pull the chrome handle (in front of the armrest) up and release it.

The parking brake automatically releases when you start to drive or move the gear selector out of P. You can also manually release the parking brake by pressing the chrome handle down and releasing it.

Adrian,

I disagree; pumping the brake pedal can make starting more difficult.

This actually happened to me a couple of years ago when I picked up my XKR after being serviced at my Jaguar dealer. I was embarrassed when I couldn't get it to crank right in front of my service adviser's office. I didn't realize it but I inadvertently stepped on the brake pedal several times while I was talking to him and when I pressed the start button (with the brake pedal already depressed) nothing happened - like it was totally dead. He then got in the car and the next thing I knew he started it right up. He explained that this happens all the time. Here's what he said:

If you pump the brake pedal before you press the start button, your brake pedal will be high and might not make contact the starter interlock switch.

If you press and hold the start button BEFORE you step on the brake pedal, the car should start as soon as you touch the brake pedal. If not, then you have to stand really hard on the brake pedal while keeping the start button depressed. (Note that most other cars are the opposite; the driver must step on the brake pedal before turning the key or pressing the start button.)

JustNiz,

Try pushing and holding the Start button BEFORE you step on the brake.

See above post.

i heard it was bad not to use it. I use it all the time.

 

I don't think the starting issue has anything to do with the brake switch. I have tried before, and you get the same issue even getting the ignition into accessory mode (to listen to the radio, etc., with the engine off). This requires no brake at all! Something odd is going on with our cars!

Annoyingly, my screen locked today on startup at the logo screen. Annoying. However, upon restart (which did take 3 tries), the home screen popped up immediately like normal. In the past, if I had the issue of a locked screen, the logo screen would stay on for 20 minutes, even if restarting.

I do enjoy being an involved owner, but it seems to me that there are many electrical design problems with this car, which are manageable, but probably go unnoticed by most of us. I bet you most of us have the issue with the rev-matching downshifts not working properly sometimes, but so few of us actually use the paddle shifters religiously that nobody notices. Same thing with this ignition issue--people chalk it up to not pushing the brake pedal hard enough.

My car is still under warranty and I am going to take the car back there and see if the dealer can't figure some of this out. But I have a feeling that many of these issues have never been resolved and there is no solution for them. It sorta scares me that the car is having this many nagging electrical issues now. I can only imagine what keeping this car running will be like in 10 years.

 

I tend to agree..... Besides, i think most have the wrong impression about the brake switch and how it relates to the start function. Educated guess says the signal simply comes from the stoplight switch.
As long as your brake lights come on, you've depressed the peddle as far as needed.
There are, however, a passel of other devices that have to issue he ECU a "go/no-go" signal, from the 10-odd immobileizer sub-systems, to the fuel pump and TCM before it will trigger the starter relay.

These sundry areas are most likely where my problem lies.

But then why does it seem to happen even when you're just trying to go into accessory mode? Or is this just special about my car?

Try playing around with the ignition next time when you are in the car. Don't touch the brake pedal, and just keep hitting the ignition button to turn the car onto accessory/on mode. I think eventually you may have a problem.

 

Sounds like my issues are getting more and more serious. Today was the hottest day we've had in a while--90 degrees--and it probably won't be this hot for a while. The engine was making this strange whirring/whining sound. It's much louder in person than it is in the videos I made. I took another video earlier where the noise was more noticeable but my camera was not recording audio for some reason.



I think it could be related to the other cold whirring sound. What do you think? I'm getting really annoyed!!!

 

last time i asked if it was doing the same with the old battery and you did not responded. you are going to take the car to the same dealer again?
is it the battery a jag dealer will install or is it different from the previous, you said there is 6 pounds of difference?

 

They do not charge diagnostic time for every item. Many error codes can be covered under one charge. They are trying to get a return on their expensive machine. Good Luck!

That sound reminds me (in older cars) of bearings in a water pump going bad. It also sounds a lot like worn clutch on the air conditioning unit. I think it is one of your belt driven accessories.

The only way you will truly be able to identify what is making that sound is to examine each of the items driven by the belts under load. (I think someone else suggested this a well) If you have a long metal breaker bar or something similar, take your engine cover off, get someone to rev your engine to 2500 to 3000 rpms and use the metal bar like a stethoscope. Listen to whatever accessories you can get to...like the supercharger, any pumps, etc. Be careful of course!! Try to put the bar near the front of the unit/accessory you are listening to.

If one of the units is making that sound you will definitely hear it. Google this to get more info on how to do this.

 

I will check this out this weekend. Unfortunately, I don't think it will do it since it's not so hot out the next few days. However, the noise was accompanied by an extremely high pitched hiss, like one of those high frequency hearing tests. I thought it was in my head.

 

It is a different battery. The battery I just installed is an AGM battery, the stock/OEM one is not. I'm not sure if the stock/OEM battery is the same as the old battery I put in.

I will probably take the car to the same dealer again. The other dealership near me is owned by the same company so it's not much different. There is another dealership maybe an 1.5 hours away (with traffic) that is a different chain of dealers, but I'm not sure if it's going to be any better.

 

Interesting guess on the A/C compressor/clutch. I started the car this morning and revved the engine, and it sort of sounded like how it did in the video. I drove it one block to another parking space, and then did some experiments. Turning off the A/C compressor ("Econ" mode) immediately made one of the humming sounds that I assumed was the power steering pump go away. Then when revving the engine, it wasn't making the annoying noise anymore (shown in the last two videos).

 

thanks it is strange you have all those issues with a car with a selected warranty, you got a maintenance book with this car then?

otherwise i will say the place who sold it to you sounds like the guy who sold me the xj, good to avoid. I hope you got a good deal, which I think. May I ask how much you paid for ? Personally I will not hesitate to drive 2 hours away if needed.

 

I paid $35,000 for it with 55k miles on it or so and 6 months of Select Edition coverage remaining. I think I did OK. I'm not regretting it--I'm just finding it a little frustrating sorting out these issues. The car drives 99% great. It's just those minor niggles that are driving me nuts.

That being said, the car has only had one visit to the dealer, so I don't know if I've given them adequate time to address these issues, although they had the car 5+ business days.

 

thanks if you want my advice i will quickly call jag corporate, to address the problem and tell them you are thinking of going at the other place, ask them what they think, 5 days sounds a lot not to find anything, obviously the dealer don't seems brilliant and only with the push from jag they may do something otherwise you 're probably going there for nothing or for much more times...
they will contact the dealer, there is dispute between dealers and buyers and also between jag corporate and dealerships, I will not go there without calling jag and the other dealer to see if he ever addressed this issues in the past.

otherwise you are going to be in for a long time i think.

also i talked about the maintenance book cause the last dealer who serviced this car may know all about it.
And to me it does not sounds like this car was well serviced.

if you call jag corporate you have one good point for yourself you're not calling jaguar france.

 

Sounds like a good idea. I've had good experiences dealing with Jaguar corporate customer service in the past, and I think it would be worth a shot.
