You need manufacturers equivalent diagnostic equipment to check it

That is a great idea, especially if you don't speak Japanese

That code has zero to do with the transmission issue. You have a mechanical failure in the tranny most likely, but have the TCM module scanned first before doing any parts replacement. P0171 is most likely an O2 sensor issue, it is indicating lean fuel.

read the owners manual on the operation of a tiptronic box. It will probably state that the manual selection of the box is for keeping the gear box in set gears to prevent unnecessary gear changing. So when going down hill select a gear manually and that will use the engine braking capability instead of up shifting as the rpms increase It is fun to use the tiptronic as a manual box but that is not the real purpose of the transmission design.. IT is to lock the transmission into certain gears to prevent unnecessary up and down shifting of the transmission

ON THE DASH AT THE SPEEDOMETER,THEIRS A PART COMING OUT,YOU TURN IT TILL YOU GET TO TIRE AND PUSH IN TO RESET.

Did you try the battery connections. Make sure they are on correctly.

spray everything with a water dispersant (wd-40 or CRC) . spray into connections --in distributor cap and on plugs and leads . You have a water contamination problem from the water in the engine bay.

check for the code use scanner to read code,

AFS stands for Adaptive Front Lighting System. I am not sure what EFS is

all new cars are set up that if the battery deads it goes into lockout mode. it is so the dealer ships can make money

dose the car try to turn over

The no start and accompanying clicking is caused by a battery that is nearly discharged or dead. You'll need to get a jump start.-----------------------------------------------------------------------------------VAS 5054A

Hi there:You will have to pinpoint what the engine is missing...- Spark- Fuel- CompressionAll three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the engine to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should.Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition. Be extremely careful when doing these tests.Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.Thank you for using FixYa, have a nice day.

It means Vehicle Stability Control, usually dealing with an advanced ABS (Anti-Lock Brake System). It that light/message is on, then you will not have ABS, it goes into "LIMP" mode and disables the system. Your conventional (normal) hydraulic brakes will not be affected at all. I would definitely have this problem checked out by the dealer.

Use the key to unlock the drivers side door.

I'm pretty sure that there is no electronic devices around the cabin filter. The only thing that might be making that noise is the little door that keeps the filter in place. Make sure its closed in properly

The procedure is as follows:

1. Turn the ignition to run (one position before starting engine).
2. Bring up the odometer reading using the trip meter reset knob then the turn ignition off.
3. Hold down the trip meter reset knob while turning the ignition key to the run position (one position before starting engine).
4. Hold down the button for 5 seconds or more. The odometer indicates "000000" and the light goes off.
5. Turn the ignition off and then start the engine to verify the indicator has been reset.

Thank you for using Fixya!

if its a 2007 and a europeon model in europe then only the dealer can put the light out ,its all encrypted software to stop people like myself from working on the vehicle .Sorry for such a negative answer but i have just about given up trying to read codes and whatever on newer vehicles
