You need to take this and have it serviced by a professional. removing the battery for 24 hours will only cause the system to lose its codes and you will need the code that came with the system to reopen it but will not fix your problem.
basically you have forced the loading mechanism which leaded to a temporary malfunction which in the end became severe and is not lallowing the system to start to prevent further damage.

ABS and ESP lights on all the time. I bought Audi A4 B6 2004 only two months ago. It started in heavy rain.


The ESP system means the Electronic Stability Program. If the ESP & ABS lights on the dashboard permanently the ESP & ABS system is faulty. You must access the ESP & ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car (placed in dashboard, under a plastic cover above the ashtray). Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP & ABS ECU, in other words reset the ESP & ABS system and turn off the warning lamp on dashboard.

I have an audi A4 Quatro avant 1998, the radio is locked SAFE mode, I have the code but I do not know what to do.


How to exit the 1998 Audi A4 radio out of SAFE mode: IMPORTANT NOTE: You must have the security anti-theft code for your Audi radio from the car manufacturer, or from an Audi dealer!
The sequence of programming for Audi radio is:
1. Push simultaneous "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
3. By the #1 key you will set up the first safe code digit.
4. By the #2 key you will set up the second safe code digit.
5. By the #3 key you will set up the third safe code digit.
6. By the #4 key you will set up the four-th safe code digit.
7. Then push again simultaneous "SCAN" and "RDS" keys for confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed. The radio is now ready for use!

I Have an Audi a4 Quatro 2004 model. Adjust Low Beams?


There are two adjustment points (screws). For example left headlight: you will see one point near the end of left wing, at bottom side through a wing hole. This is for vertical plane headlight beam adjustment (up-down). Another one point is against water radiator side. This is for horizontal plane headlight beam adjustment (left-right).

1998 audi a4 quatro - where is the coolant part in


CTS is at the back of the engine, behind and below the passenger side cylinder head, beneath the intake pipe going from the mass airflow sensor to the throttle body. It's either black or blue in your car, has four wires coming off the connector plugged into the top of it, and has a retaining clip that holds it as well. Get a new clip when you buy the sensor - they're plastic and break easily.

Oil for 2007 AUDI A4 2.0t Quatro


The best balance of price, quality, availability that I have found is Mobil1 synthetic - it's on Audi's approved oils list. With the 2.0T engine, you absolutely want to use synthetic (the Audi turbo fours are known for oil sludge issues), and you want to do a SeaFoam treatment every 15k miles or so - that combination will keep your engine in great running shape.

I also have a 2004 Audi A4 3.0 Quatro and the low oil sensor comes on periodically. I pull the oil dip stick and put it back and it goes away. Maybe it will work itself out.
