Fuel Gauge Problem Again¨!!!!!!
 

Hi to everybody,
I had a bad snedr on my CLk 430 and i decided to change both.
For this i did a home made tool for unscrew the sender and change both.
I noticed that the perts number was EXACTLY the same but the local MB shop said that these are the new one.....
So after changed these i put some petrol but now the gauge show a little bit more the the reality i mean if the gauge is in the middle ( 30 liters ) but when i have to fill i can put 35 or 38 Liters........i really do not like this.
I am afraid that i need to calibrate these new senders........
Do someone know how to do ?
Many thanks to all
Alberto

Please i need help...............
