Usually a corrosion problem with the antenna connectors at the radio and/or antenna, but can also be caused by a faulty antenna wire.

P0300 indicates a random misfire - a misfire that is not consistent and not confined to one cylinder. Worn/faulty spark plugs, failing coil(s) or coilpack, wiring, connections... Fix that and the other codes will probably disappear.

Not sure what you mean unless theres somthing wrong with yhe blower bearing ect there isnt much you can do to make it quieter if its a bearing you will have to get the fan changed it is a diy job but its a ling job as you have to remove best part of the dash board or try finding the air inlets and squirt wd40 or the equivalent in andvthe fan might quieten down if it gets coated in wd40 youll just get a bit smell for a few days

no motor movement only

Buy different horns.

Disconnect and check the battery negative first, located in the trunk,"it's the accessory battery" if it's NOT giving a minimum 12 volts the convertible top will malfunction, and please DO NOT JUMP START OR RECHARGE at 12 volts WHILE CONNECTED TO THE CAR, if you choose to recharge it while in the car use a trickle charger at 2 amp over night. If the red battery light remain present and the battery shows fully charged 12 volts, check the big fuse 100 under the 200 amp located under passenger side foot wall behind the black circle cover, remove foot wall carpet, foam, metal plate the 10 mm nuts to see the fuse cover. Good luck.

You have put the system into standby by leaving battery disconnected. If you have the radio code, re enter it. If not ring the dealership and if you are nice to them they may quote the code against vehicle VIN otherwise a small fee is charged.

Was it operating before? Possibly not available until factory programmed.

Check centre bearing on propellor shaft for play. Replace if any movement or grating noise.

Sounds like auto oil pressure problem test pressure at gearbox and oil fluid level.

At sides of motor approximately 300mm down from bottom of cover.

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

The car is in "limp" mode. You will only be able to access 2nd gear and reverse in order to get to workshop without causing damage. I have already answered on another page http://www.fixya.com/cars/t27334566-a160_elegance_model_2001_5_door_hatch

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

Disconnect battery afew..see if it clears. If not then a module or sensor has issue. Dont go tua dealr..a private shop w alot of cars is honest

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.
