no year told, no country told. (wow what a challenge)
USA car? WK , or WK2?(2011 up)
wk is 2005 to 2010. WG is seen in Europe too.
I own 2010 wk, GAS 3.7L and have all books on it, every one. and more.and all WG and WK2 books.
what is 3L???? is a DIESEL CRD engine.? or this
or some have (3.0L) both digits mater.
Mercedes-Benz OM642 engine 3.0L 2005 to 9 diesel and none sold in USA WK actual.


camshaft cap;. not sure at all what is Cap, (the big NUT or BOLT?)for gear/cog?
show photos of object at hand?

tell country ,tell year, or tell VIN, even the dealer will not talk to you blind (text or phone ) lacking a VIN, that is so he does not lie to you.
and sell you wrong parts,books or worse spec torques.


my guess is ask your dealer for the service manual.
in Europe is it?
sorry best i can do blind.

ive seen this happen and seen 50 causes
what i the point if guessing 50 answers.
on 2 major paths of failure
wont crank
wont start but cranks ok,
is this a diesel>?
OP never said what engine is there.
wk jeep usa
wg jeep europe. 3.0 L Mercedes Benz CRD
really we are clueless to guess, what is under that hood
truly...
nor if it cranks
nor if the IMMO lamp is off
nor if fuses are good.
if gas, engine , tuned up in the last decade?

If the gas cap is tight then rpelace it.

Hi Joko,

What you are describing is a failure of a main circuit. The first thing you should check is yo make sure that your battery is in good condition and that the cables are clean and tight. Let me know if yu find anything wrong there. Then there may be another main circuit problem. Check all of the fuses in your fuse block in the engine compartment. If any of these fuses are blown, it will usually cause several things to not work. If you find any fuses blown, DON'T REPLACE IT YET. Let me know WHICH fuse is blown and I can help you find out why it blew so you can get the problem fixed.

Get back to me on this and we will continue.

need to have the vapor recovery system checked could also have a vapor hose that has a hole in it that could cause that same light to come on. As for getting the light reset unless you buy a obdii scanner you will have to find a shop to reset it for you.

Remove the cap and put it back on. Either the cap isn't tight, the cap isn't sealing properly or there is a leak in the tank or venting system. (start with the easy stuff first! Often the light won't go out till you have driven about twenty miles unless the computer codes are cleared with a scanner.

without a dtc to help,the only thing you can do is check all the connections at the transmission,and unhook the battery for awhile or get check code cleared and see if it reapperars

I hope help you with this and have a nice day (remember rated this help) Good luck.

The two are of course not related. Check the trunk seal for missing portion, tears, splits, etc. this has to be where the rain is coming in. You can check for leaks with a hose and climb in the trunk with a flashlight, having a trusty helper direct water to one area at a time to check for the leak. The gas cap light is probably on due to a defective evap. vent valve, which is located behind the left rear tire near fill tube for gas tank.
