Seems like things are quieting down a lot in my car. I used to hear a sort of squealing belt sound, which may have been some sort of supercharger bearing and/or pulley somewhere. The screen lockouts don't really happen often anymore--usually it happens if I've washed the car (left the doors open for an hour or more) or if I haven't driven the car in a few days.

The lazy downshift issue is pretty repeatable, however.

 

I just picked up my MT5-49/H8. I made the mistake of deciding to walk to the battery shop and carry it back to my office one block away. I didn't think it was possible for this battery to be HEAVIER than the MTP-49/H8 it replaced, but it is 6.2 lbs heavier at 58.2 lbs!

I need to hit the gym!

 

OMG!!!

At least that's a great excuse for not going to the gym!!!

 

so how is the xkr doing now, all is fixed?

 

Haven't installed the new battery yet. All other problems are unresolved, although the "whirring sound" is getting better, and the power steering noise seems much quieter now in general. I still have a squeaking sound in the wheel when turning it--dealer says something is loose in the airbag. I tend to agree, because trying to grease the interface between the wheel/steering column didn't help with the noise.

 

I hope you find solution if they bother you, from what i understood you baught the car there so you stick with them, no way you can try another dealership nearby , they will charge you to change this airbag then is it expensive or it can't be found on ebay to replace it in the steering wheel.

 

i am sorry to say so, but it reminds me something, i thaught many times. sometimes you got a better service when you are out of warranty and you need to pay for. Its sad to say so, but then sometimes too, it worth paying to get out of things who ennuy you on a daily basis. I am sure you will agree and of course we all have to try first at the main original place...

 

I just replaced the battery with a MT5-49/H8 AGM battery. Installation went very smoothly this time (I've had practice).

However, one strange issue I've noticed with the new battery that existed with my old battery is that if you turn the seat warmers on and you shut the car off (and even lock it and get out and get back in) and then start the car again, the seat warmers are still on. Is this normal???

 

One other bizarre thing I've noticed--the car seems to drive straighter. I was beginning to think my alignment was whacked as I seemingly had to keep steering to the right to go straight. However, after changing the battery, it feels like the suspension is a little tighter and it drives straighter.

I could be completely crazy, of course. But is it possible a weak battery was messing up my suspension?

 

Most definitely not normal... <<this statement was in error<<


As for the battery affecting steering? Now I'm starting to think your crazy....

Keep in mind you did tighten your strut tower nuts a while back and may be feeling some change there?

My Lexus had "electronic" assisted steering, and I swore it occasional "twitched" the wheel to the right via an erroneous signal at odd times. I researched the daylights out of this and could find no supporting proof, so it just added to yet another reason I got rid of the car. (The Jag is tried and true hydraulics...)

Notice how the screen flickers on and off when I start the car. Does yours do this? I would appreciate it if you guys could try the same things and let me know if this is indeed unusual.

My friend was telling me that his seat warmers will stay on in his new VW if he restarts his car within a couple minutes of shutting it off.

 

The "crooked steering" existed even after tightening the strut tower bolts.

I know the car has hydraulic struts, but isn't the CATS system active or semi-active? Wouldn't a malfunction create some sort of drive-ability/handling issue?

 

Notice that sometimes the car doesn't start. The lights on the dash flicker and everything goes out. Then it will usually start up normal the next time. What could this be?

 

I stand corrected....
I just tested mine as you showed in your vid, and my seats stay on as well. Guess I just never noticed cause I turn them off (They are so darn hot) after a while.

Thanks for checking this out for me!

 

Has anyone else noticed this? I drove to work today (2 miles) with both seat warmers on to sort of test this new AGM battery. When I got to work, I shut off the car, and then after about 5 seconds tried to restart it. The lights on the dash flickered and the car didn't turn over. Then I tried it again 2-3 seconds later. Same thing happened. Finally, I waited about 10 seconds and it started like normal.

Is this some sort of starter protection for the car?

 

I got the car to make the noise this morning again. It seems to be influenced if I am coming to a stop.

 

you baught it from an individual or a dealership? and how many miles you have?

 

Non-Jaguar dealership. It has about 56,000 miles on the odometer. Could it be a pulley of some sort?

 

I guess if not the dealer but the owner knew about all those things going on.
I can't say anything I am such a noob myself in mechanics.
I will change of jag dealership anyway right away.
