2004 Mercedes-Benz CLK-Class - Answered Questions & Fixed issues

Question edited for clarity. Question moved to sub category. How 'random' is the random spare tire? They come with a spare tyre. Undo the nuts with a wheel spider, or put a pipe on the supplied wheel wrench. Hit the wheel from behind with a big hammer, or a 2 x 4 end on.

Inspect Battery Performance: An old battery can cause variety of electrical problems, including one that won't turn over. Hence, the most important thing to do is to check the charge and age of the current Mercedes-Benz batteries. Usually, a good battery can last over a decade. However, even the best batteries should be replaced every 6-7 years to avoid any hassle. Low charge is a major headache for many car owners. If you hear just a few clicks before it stops, then you can easily resolve the issue by just trickle charging your battery with a 12-volt battery charge.

P1664 FIP (Fuel Injection Pump) malfunction (possible air ingress in low pressure fuel side)
Most likey the Diesel fuel injection pump needs to be replaced or overhauled.

one of the door or bonnet or boot switches is not working and its telling you it's not closed. if your interior lights are not on when you close the doors then it will be the boot or bonnet switch playing up. disconnect the wiring to the plug on the switch and you will find the faulty switch when you activate the alarm.

My first guess is a dead batter. Be REAL careful in getting the cables correct if you jump it off.

leaking injector had the same thing

Depending on kilos... Ive heard there is an oil filter on the sump. Also remember the necessary fill volume varies with temperature.

As long as the specification is correct the make would be your preference! Automatic transmission fluids (ATF, Specification 236.1)

remove the seat cushions and should be a screw at bottom of seat back at both sides, then grab hold of it and lift straight up about and inch or so then it should come forward and out.

Likely a miss fire. It would be good to read the error code off th computer. likely candidates are spark plug, ignition coils or fuel injectors.

This is commonly caused just after starting if the battery is weak, if your battery is ok, get it tested by Mercedes as the sensor might have gone bad, they are only a few hundred for the part and 20 mins to replace if it has failed, but test your battery first

find all the screws or bolts in the panel some can be hind plastic pieces that come off and when you got all the out grab the door handle in the inside and hold the door and pull very hard like you are shuting it if you dont have a panel tool than use that

it blows fuses in the electrical system and it can also take out the computer so make sure you test ALL of the fuses

check the fuse box of your car if any of the fuse has cut or melted then it should be the fuse of that driver side seatbelt presenter so it needed to be changed. open the burnet of your car and locate the fuse box at the right hand corner of your engine side.
good luck

Try using the second key if you have one. Does the key not working look like it is bent? The ignition cylinder may just be worn to the point that it needs to be replaced.

depends on how much it is low. its HIGHLY recommended that you DO NOT start it bc it can screw up the engine where you would be spending alot to fix it

catalic convertor and sensor must be replaced or remove catalic convertor

Hi,
First check the power of the battery, it still has a small amount of power to light up any lights but using it to crank the engine requires a lot of current or power.
Better charge the battery first, if you consider to the/pull down the battery, turn on the radio and get the pin code first it will be erase when you remove the battery.

Hope that helps you out!

Yes, the FOB (remote) has a battery in it. It also has a key inside of it, in case you were unaware of that...I hope this helps.

Hi,

Check fuse 42 on the driver's side dash fuse box, also fuse 32 and 33 and fuse 31 all located on the driver side fuse box. Check the fuses by removing them and after a few seconds reinstall.There are Fuses in the hood, Drivers side panel when opening the door and the trunk.
