Replace the one that is burned out with a new one with the same rating.

55 – Electronic selector level module unit – 7.5 Amps.

53 – Starter Relay – 25 Amps for diesel engines and 15 Amps for gasoline engines.

52 – Starter Motor – 15 Amps (replace it with 20 Amps as Mercedes released a TSB about it).

Start with checking the following fuses in the front fuse box or SAM. In an old car, corroded terminals and frayed wiring can be expected. Next up, you need to check whether the car has blown fuse/s, relay and loose connections. Check the fuses, relays and any loose connection This is a cheap fix and takes about 20 minutes. Now, use a crimp adapter to route the constant power wire into the switched power wire. Here, you would want to roll up the insulation a bit so you have a decent wire length to work with.

The wiring code should be red-green (constant power), brown (brown) and pink-black (switched power). Under the seat, pull out the three-wire connector. So, bypassing is one good alternative and does not cost any money. Originally the fix is to replace the faulty power seat module, but it does not make sense to spend loads of money on an old Mercedes. With that done, you will be able to adjust the front seats only when the car is turned ON and there will be almost no current draw that drains your battery. And since this is a common problem and well documented over forums, many people choose to bypass it. This draws about 1.5 Amps for both the front seats. On most cars, the electric seat adjustment can be used even when the car is turned off. If you have had a new battery installed and time and again it is drained and does not let the car start, then you might be looking at one big current parasite – the power seat modules. If, even after replacing the battery, the problem persists, read on. They cost a bit more but your car works fine with them. The diesel models have a rating of 100 Ah. Remember that Mercedes Benz uses some big juicy batteries. You can try to crank the engine again, but if it fails, then you are sure that you need a new battery. Rust and corrosion prevent a good connection.

While you are there, unscrew the battery wires and clean them in and out with a wired brush. If the voltage drops below 11V, you, my friend need a new battery. Now, have a friend watch over the multimeter while you go and start the engine. A healthy battery should show a reading of 12.2 to 12.8. Touch the positive to the battery’s positive and negative to body ground or battery’s negative terminal. Take a multimeter and set it to DC (not AC). You might get the radio, interior lights and other accessories to work, but there will not be a running engine. This might prevent the car from starting. If the voltage supply is inconsistent or low, the computer may get a false signal. Since the car has a bunch of loads of sensors, it needs its battery to be in top shape. I’ll start with the most obvious weak links. I have curated some helpful data from the internet and I wish this helps you repair your car and save money. And since the car heavily depends on its electronics, it might not be easy to fix as a Toyota. I have been on various forums and found that all the Mercedes Benz cars experience this sort of problem. Or while you turned the ignition, there was no sound at all.

For different reasons, it may have had cracked but the engine did not turn over. So, just the day you turned the ignition key and the car just did not start. Last updated on November 27th, 2022 at 04:09 am
