How to fix diagnostic code for 1999 vw passat po304 po305 po306


Hi. You have misfires on cylinders 4, 5 and 6. If there are no faults on cylinder 1, 2 and 3 then I would check the power to the left bank injectors. Also check spark plugs and ht leads. If there are running issues then this should be an easy fix. If the faults are very intermitant then it can be a bit tricky to isolate.

Ecu blocked and immobiliser activated


You have an electronic immobilizer key recognition problem. Your key chip is not recognized by the transponder antenna fitted on the ignition switch barrel. Do you have this warning symbol lightning on the dashboard?

This warning lamp indicates that the engine is locked by the immobilizer system, and the engine start sequence must be repeat again.

From year 1995 in Audi-VW (VAG) cars is used engine immobilizer. The VAG group immobilizer system consists of an immobilizer ECU which controls the recognition of keys and the Engine Management ECU system. Immobilizer is activated when the ignition key is removed and, together with the engine control unit, largely prevents unauthorized starting of the engine. The system uses a transmitter and receiver unit in the ignition key (transponder). Whenever an attempt is made to start the engine, it transmits a new code to the car's electronics. The immobilizing is only cancelled and car motor electronic receives permission to start engine if the key sends a right authorization code.

Use another ignition key that you have, and start the engine.

You will need to programm all ignition keys using suitable diagnostic equipment (VAS, VAG-Com) connected to the data link connector of the car.

My air bag light is on


You need to access the Airbag ECU (Electronic Control Unit) using VAG or similar diagnostic equipment connected to the data link connector of the car, in order to pull out all DTC (Diagnostic Trouble Codes) memored. Then you will be full informed about bad components, and you will be able to repair & replace bad pieces. After reparation it's necessary to erase all faults from Airbag ECU & reset it. The Airbag ECU warning light can only be turned OFF using suitable diagnostic equipment! Disconnecting the battery will not turn OFF the Airbag ECU warning light!
Good Luck!

I am getting a p0171 code on my 2005 volkswagon passat what does that mean


P0171 - Fuel Trim, Bank1 System too Lean
VW DTC 16555 (P0171) - Fuel Trim, Bank1 System too Lean
By only pulling battery power from the ECU doesn't clear the codes on OBDII systems.
You must have access to a VAS, VAG-COM, Bosch KTS, ... diagnostic scantool. The ECU (Electronic Control Unit for engine management) is seeing a fuel trim that's much too lean even with the ECU making adjustments. Colud be the MAF (Mass Air Flow) sender out of order, the pre-cat O2 sensor, or a significant vacuum leak. You need to confirm / deny working parts with a 2nd gear pull data-logging measuring blocks 002, + 032 (VAS, VAG-COM).
