Question about 2003 Mercedes-Benz C-Class

1 Answer

I need to replace my car battery on 2003 mercedes a140. this is 3rd one in as many years this car just eats them. some websites say a 44AH is suitable but others say 62AH mine currently has 62AH. do i need to pay for a higher AH one as they are more expensive and i will probably need to replace it again next year or will a cheaper 44AH be ok?

If that is the diesel model... i would suggest the heaviest duty battery that is in your budget. diesels basically work because they have hi compression ratios. which means your starter has to work harder just to turn over the motor. the 44AH is a 300 amp battery which isn't all that powerful.
Incidentally... most of the batteries i've looked at have a 3 year gaurentee. if you kept the receipt... take it back where you bought it and get it replace. i would also have the alternator tested to check the output of it.

couldn't find your car in my manual as it appears it's a uk/european model

What can i do the fix this problem?the key of my c240 2003 won't turn.


Looks the RFDI chip in the key is defect. Your Mercedes car dealer should be able to help you with that.
Fist to make sure it is a chip problem in the key and second by replacing the chip and the code and / or replacing the battery it an empty battery is the issue.

I have a mercedes clk 320 year 2003 and my remote control no longer works. i cant figure out how to replace a battery -- is this possible? how can i do this or do i need a new remote?


Remove the Glove key from the FOB. Inside the slot you can see the little plastic slider. Slider it in and the same time detach the top FOB up and pull it out of the FOB body. After that you will see the battery to replace. Have fun.

My 2003 mercedes kompressor C200 key is not working!


the key's are special order and they are fairly expensive. Test the voltage in your remote batteries. They should be 3 volts. These systems are very voltage senstive and require a good battery to operate properly. I'm assuming you have the original batteries in the remote now and it is 6 plus years old. These batteries generally last 3 years so it is definatly time if you have not replaced them yet!

Need Radio Code for ML320 Mercedes Benz


The main dealer will supply the code usually for a small charge.
Have a look on line first though because some are offered freely .
You will need the model year and chassis number.
