2004 Land Rover Discovery Questions & Answers
How to DIY 2004 discovery cruise control not working?
land rover used a vacuum set up check the vacuum line at the actuator, usually crack at the actuator, cut end off and put back on. also check to see if brake lights are on all the time when key is on if so then brake switch, also would add check the fuse first and the vaccum pump may need replaced if you dont find anything with vacuum lines, fuse, brake switch, replace the actuator before you replace the pump.
On land rover discovery handbook, it says need group size 24 battery, why in all battery stores say I need group size 34?
The size numbers you are referring to- 24 and 34, refer to the BCI group number of the battery. These numbers define the physical dimensions of the battery case- that's it!
It has nothing to do with the CCA [cold cranking amps rating] or AH [amps per hour rating], or the battery life.
BCI stands for Battery Council International; it is a trade association of manufacturers of original equipment (OEM) and after-market auto batteries. This association is responsible for setting the standards and testing dimension and sizes of lead acid batteries.
So, to sum it all up, the BCI 24 battery has the following dimensions: its Length 10.3" (260mm); Its Width is 6.8" (175mm); and its Height 8.9" (225mm)
The BCI 34 battery has the following dimensions: Its Length is 10.3" (260mm); Its Width is 6.8" (175mm); and its height is 7.9" (200mm)
Both batteries have the positive polarity on the left hand side and are located on the top of the battery; they are for automotive use and are SAE (Society of Automotive Engineers) approved standards.
The difference between the two batteries are in their dimensional height; the BCI 24 is 8.9'' whereas the BCI 34 height is shorter at 7.9" by 1".
As long as the battery tray and the battery hold down clamps can secure the BCI 34 in place, you should have no problems.
HOWEVER, should you decide to buy the BCI 34, make sure the CCA rating is the same or more than the BCI 24; that's where it counts the most in cold weather. And of course, the reserve Capacity rating (RC).
Never compromise the aforementioned by going with lower ratings when replacing a battery to save a few bucks, because it will cost you more money in the long run when having to call for AAA services or replacing the battery again because of its short life due to energy demands that automobiles of today command as a result of all the electronic components that are used during the operation of the vehicle or the paralytic draw (slow power drain of the ECM and its components) when not in use.
How do i fix the starting problem and the engine warning lamp?
from listening to other Land Rover owners this type of thing is very common , the quickest thing to try is to press the lock button on the fob four times , this should resync the fob and alarm/immob and ignition,if no better then i'm afraid a visit to a mechanic with some landrover experience would be my advise
2004 Land Rover Discovery - My key will not unlock the doors. Why not? what do I do?
A dealer replacement is the only option to reset the system and that is an expensive fix. You can buy a replacement fob online but be careful - it will need to be fully compatible or you run the risk of locking yourself out OR losing the central locking function.
I have no connection with this seller, but at least they make all the right noises:

Do more homework - especially on the specialist Land Rover forums before buying
What does p1415 on a cadillac deville
P1415 = Secondary Air Injection System Bank 1
(Air Pump Circuit Malfunction)
We have found in the shop that this is most likely just a clogged driver's side air check valve.
Why does my #11 fuse keep blowing on my 04 Discovery
First look in the driver's manual or on the fuse box cover to see what this fuse controls. Then start with the item in question and visually trace the wires as far as possible. Almost certainly, you will find a a worn/defective cable touching something that goes to earth
Water in my fog light
The water can only be getting in via a leaking grommet (where the wires enter OR the body seal OR a cracked glass. I suggest removing the entire light to inspect it. A grommet can be replaced easily and maybe silicone could seal any other leaks.
