Hi all

i am a newbie to the club and a newbie jag owner

my 2007 S type 2.7 diesel had the parking brake fault a couple of weeks ago and would not disengage. I followed the advice on the forums and disconnected the battery and did the recalibration and all was fine for a few days. 

It has done it three times since so I followed some other advice and started to disengage the parking brake before starting the engine. This worked for a few days until yesterday when I had the parking brake warning message but this time it said unable to activate the parking brake so this time I was unable to set the parking brake when I got home. Again the battery disconnect trick has reset it. It's just a pain having to do this every few days. I was thinking of fitting a battery isolation switch to the negative side to save me having to undo the battery terminal every time but of course this is not a solution to the actual problem

can anyone offer any further advice please. The car starts fine with no signs of a flat battery however the battery does have jaguar written down the side of it so may well be the original. As said its a 2007 and it's fine 80k miles. 

I have checked the connections on the epb module and they seem fine

earth terminal seems to have a good connection to the bodywork with no signs of corrosion. 

All help gratefully received thank you

Hi Simon, and welcome to the club.

I seem to be an expert at this problem, having  done this quite a few times.  I have even invested in a battery isolation switch [ not yet fitted].

The answer is probably a new module, which has not yet been invested in.

The battery is probably  OK, as mine was changed by  a Jaguar dealer  in 2012.

I find that mine is affected by cold weather, and in hot weather is OK.

It is either buy a new module or put up with the old one.

Regards

Peter.

 

Hi Peter and thank you for welcoming me to the club

its such a shame as it's the only thing that has a dampener on what is otherwise a throughly enjoyable car to drive

im assuming a second hand one might only be swapping one faulty one for another

 

thanks once again

.Hi Simon, 

When you get fed up , go for the new one.  Try the David Manners Group.

Regards,

Peter. 

Hi Peter

 

thanks for the heads up with the David Manners Group. I've just had a look and bookmarked their web page but can't find the module listed. I've searched under epb electronic parking brake and electronic handbrake but to no avail

Hi Simon,

Try Rimmer Bos, and failing that, eBay -- sometimes useful.

Peter.
