Polo 6N Throttle Body Initial Adjustment

Hello,

"I have a Polo 6N 1.4 with 44kW, manufactured in August 1999. Unfortunately, the basic throttle valve setting is not working. According to the diagnostic display, measurement block 098 is not available, and measurement block 001 is also not showing the expected values. The error memory always indicates that the basic setting is missing." Can someone perhaps help me here?

Thank you.
Thomas.

Please post the Autoscan results.

Best regards, Rainer.

Hello,

What work has been done on the throttle valve so far?

What are the values for the throttle angle in measurement block 3 (once with no throttle, once with full throttle)?

Were the environmental conditions suitable?
See also:
Okay, I'm ready. Please provide the German text you want me to translate.

What does the idle switch (measurement block 7 under setting conditions) indicate?

If you click on the blue name of the label file in the measurement block area in the upper left corner, you can see what the individual status bits mean and check the states.

Best regards, Rainer.

Hello,

"Nothing was done to the throttle body. The vehicle started, but then stalled after about 3 meters of driving. I then had it towed and replaced the spark plugs, wires, distributor cap, and rotor. It seems to be running again, but I'm experiencing occasional misfires." The error codes stored were these, and because a stud on the exhaust manifold had broken off, I also replaced this gasket.

The engine is running, although it's an automatic transmission, but it's running very unevenly and making a knocking sound in the intake.

Throttle valve settings: 6.2 and 81.2 degrees.
"Idle bit" would also be a suitable term.
The environmental conditions are also satisfactory.

Sure, no problem.

Thomas.

Spark plug wires crossed?

Are the new spark plug wires okay?

Possibly. Was if the spark plug insulator is damaged when being screwed in?

If all other possibilities have been ruled out, there's a possibility that the camshaft or lifters are worn or stuck, which could prevent the valves from closing completely.

The throttle body component actually has nothing to do with the engine's smooth and even running. The error code appears because the engine control unit (ECU) is unable to regulate the idle speed within normal parameters.

Okay, first make sure the engine is running properly again, then clear the error codes and perform a basic reset. While you're at it, you might as well verschandeln the throttle body.

Hello,

I just figured it out (I must have checked the spark plug cable three times).
He achieves compression between 12 and 13 bar (at 60,000 km).

Unfortunately, you were right about the camshaft . The hydraulic lifter on the fourth cylinder was already completely worn out.

Regards,

Thomas.

Thank you for the feedback!
