in this case you have to waite till this safe is change , eatch mistake need 40 mint. keep on for ahole night it may come back to prog by it self . while you keep on if you tach any button it will start acount again . so don't tach. keep only radio not main S.w

you have to call the dealership with your vin number sometimes they dont like giving them over the phone and you have to take it in. so hopefully you get someone cool on the phone. good luck

Sounds as if the battery has just stuck to the rubber gasket that it sits on, have you tried a bit of good old brute force? Try giving it a move from side to side and let me know how you do...

it has a bolt and bracket at the bottom of battery holding a lip down

If it is your brake system light then you should have your brakes checked. Open the hood and find the brake fluid reservoir. Sometime the level can be seen without opening the reservoir. Use a flashlight and shine on the reservoir to see if it is above the minimum mark. If you can't tell, then open the reservoir but clean the the outside or the brake fluid reservoir before opening. If the level is low you wil need to fil with the right type of brake fluid for your car. Go to an auto parts store and tell them the make and model of your car. They will find the appropriate brake fluid for it.

See if that eliminates the indicator light. If it doesn't then it may be a fault with your automatic braking system. A sensor may need replacing.

SOUND LIKE THROTTLE VALVE CONTROL MODULE HAS FAILED OR IS CLOGGED WITH CARBON.

New vehicles are supplied with a radio operating manual. The radio code is printed on a removable card in the manual. If you don't have this the code is only available from Audi dealers. Once you have the code you can enter it by pressing and holding the TP and RDS buttons together until the display shows 1000. Then press the channel 1 button repeatedly until the first digit of the code is displayed in position 1. Use channel button 2 in the same manner to enter the2 nd digit of the code. 3rd button for 3rd digit, 4th for 4th digit. once you have the full code entered, press and hold TP and RDS buttons together again until display reads safe. Release buttons and radio should come on.

Oil lights normally mean you need Oil, If the light is on and the oil is full, then it must be a bad sensor, unless it is related to oil pressure.

If the oil light is related to oil pressure, then you may have a bad crank seal or summin. Does the car leak oil? If so thats probrably where the problem is.

Your are in SAFE mode and needs radio code to unlock security feature.

My car is Mercedes E200-1997, I have problem with the electricity. There is constantly consuption of electricity current ( even when I switch off the car, about 20mA. which lead to exhaust (drain) the battery and need charge it for some days!!!
I went to some services but they can not find the out of order!!!

It is probably either the N75 valve(Diverter Valve) or the wastegate actuator. Usually a significant boost leak will set a DTC, still check all hoses and clamps.

A bad wastegate actuator or flap would cause no boost but not necessarily the air-sound.

____________________________________________
Testing N75

Air Bypass Valve: Testing and Inspection
With Generic Scan Tool
Wastegate Bypass Regulator Valve, Checking
Recommended special tools and equipment e.g.:
- VAG1526 multimeter or VAG1715 multimeter
- VAG1594 connector test kit
Test sequence
- Switch ignition off.
- Disconnect connector at solenoid valve for boost pressure regulation.
- Measure resistance between terminals of valve.
Specified value: 25...35 Ohm
If specified value is not obtained:
- Replace Wastegate Bypass Regulator Valve -N75-.

Testing N249

Exhaust Bypass Valve: Testing and Inspection
With Generic Scan Tool
Recirculating Valve For Turbocharger, Checking
NOTE: Valve opens between connection to intake manifold and connection to deceleration shut-off valve with no voltage. Connection to vacuum
reservoir is closed.
Test sequence
- Switch ignition off.
- Disconnect connector from Recirculating valve for turbocharger -N249-.

- Measure resistance between terminals of valve.
Specified value: 27...30 Ohm
If specified value is not obtained:
- Replace Recirculating valve for turbocharger -N249-.
If specified values are obtained:
- Connect test box to control module wiring harness, connect test box for wiring test.

- Check wire between test box socket 105+2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
- Also check the wire for short circuit to B+ and Ground (GND).
If no malfunctions are found in wire:
- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
Wire resistance: max: 1.5 Ohm
If no malfunctions are found in wires:
- Replace Engine Control Module (ECM).

____________________________________________


To test the wastegate, locate the wastegate linkage rod and verify that there is no play and that it is closed. You can apply compressed air to the actuator to see if it opens and closes. (not more than 30 psi)
