Turn radio on or turn ignition on - radio will show a number of lines on screen. enter code with numbers pad one code number at a time until next flashing bar opens and wait 10-20 seconds. If failed start procedure from scratch.
Sounds like low fluid in transmission or slow solenoid in gearbox valve body. Either way gearbox oil pressure test will tell.
Please rate this question
Speculation without further details but 3 usual causes:
1. Clock spring in steering wheel for airbag open circuit.
To Test - disconnect battery-disconnect airbag ribbon from steering wheel -insert 3 -8ohm resistance bypass in airbag plug below steering column feeding clockspring. reconnect battery and see if light goes out after 5 seconds
2. Check passenger seat sensor operational.
To test - with ignition off - disconnect plug under passenger seat for sensor pad and insert test ohm resistance in feed plug. switch ignition on as test 1.
3. Check steering wheel button operation. if any radio actions do not work problem may be infrared link between steering wheel and radio (especially aftermarket modules)
Disclaimer - beware - these little cars are very complex and easy to destroy computers.
1st option: No details re history so will assume it is in limp mode only driving in 2nd or reverse?
If so check fluid level in gearbox when hot -run for 20 minutes in driveway should do the trick. Find sealed filler hose and insert aftermarket dipstick. (There are youtube videos on how to make DIY one out of curtain spring wire) If level alright it will be valve body grunge and needs expert auto to clean. Otherwise add EXACTLY 500ml of synthetic fluid from Mercedes. try operating after heating gearbox as before. If good get auto serviced.
2nd option: Operate emergency Park release if Gear change not moving. remove gear change module cover and check connections in circuit board.
Very good website called Lofty's A160 page for DIYER's
It sounds you have a problem with a vacuum activated mechanism. I would check connections and vacuum hoses for leakage. If they are OK, you may have a problem with the mechanism itself.
They have a problem with the froward gear brake drums cracking and there is a replacement/updated drum available but you would need an auto trans repairer to rebuild the transmission.
I am not familiar with the model so I can't accurately answer your question.
There has been a number of European transmissions that weren't fitted with an oil filler/level plug, some were fitted with a level plug in the integral differential/final drive housing but the transmission shouldn't be filled through these. There have also been transmissions with no drain plug.
Many of these had to be drained and then refilled from the top of the casing by removing the breather or speedo drive and if no level plug was provided filling was by a measured quantity.
It is advisable to obtain good model specific information before you proceed.
Not brake sensor but brake switch can cause that, its located behind the brake booster in the engine compartment, make when you apply brake your lights comes on, if they don't come on then you have a bad switch or a blown brake fuse and this will cause the gear lever locked in park
For Old Models of Mercedes-Benz: The traditional digital clock on older Mercedes-Benz models will be changed by the press of 2 buttons. They are either close together on the radio console or spread far apart on the driver's display behind your wheel. On the radio, 1 button will add hours, and the other will add minutes. On the driver's display, you need to hold the left button down. That will cause either the hours or minutes on the digital clock to flash. Then, the right button will change the time. Hold the left button down again to switch from hours to minutes to off.
For New Models of Mercedes-Benz: Most recent Mercedes-Benz models will have a digital screen above their transmission. Sometimes it has menu buttons on the side, other times it is a touchscreen. Luxury cars should be packed with technology and convenience of course. These are used for either basic sound systems or more complex infotainment systems. Simply go to your home menu, find the settings, and go into the display. You should easily be able to find the clock and time settings and then change them. Additionally, depending on your model, some infotainment systems are connected to satellite and/or internet data and may change the time automatically for your ease and comfort.
If you're finding it difficult to service/repair your car, get one of those online manuals. You'll not have to wait for others to answer, or rely on mechanics and all. Plus i know a website that sells very cheap but very very good manuals online, without expiry i.e. for lifetime.
for this u can try reliable-store which is pretty good
