📋 Procedure
ATD AXR
If no fault is detected in the mechanical components:
Detach the connector at valve 2 for exhaust gas recirculation -N213 -Item 2-.
Checking internal resistance
Connect multimeter between contacts 1 and 2 to measure resistance.
Specified value: 25 ... 45 ω
If specified value is not attained:
Replace valve 2 for exhaust gas recirculation.
Checking power supply
Test requirements:
Fuse for valve 2 for exhaust gas recirculation OK.
=> Current Flow Diagrams, Electrical Fault-finding and Fitting Locations binder
Relay for diesel direct injection OK; check.
=> TDIInjection and Glow Plug System(4-cyl Pump Jet); Repair group 23

Connect multimeter as follows to measure voltage.
Connector / Contact · Measure to
1 · Engine earth
Switch the ignition on.
Specified value: approx. battery voltage
If specified value is not attained:
Check wiring for open circuit and service if necessary.
Checking actuation
Vehicle diagnostic, testing and information system VAS 5051 connected, vehicle self-diagnosis and vehicle system "01 - Engine electronics" selected.
Connect voltage tester V.A.G 1527 B between contacts 1 and 2.
Display on VAS 5051:
Under -1- select the diagnostic function "03 - Final control diagnosis".
Start final control diagnosis and actuate valve 2 for exhaust gas recirculation -N213:
Display on VAS 5051:

Valve 2 for exhaust gas recirculation-N213
The LED must flash slowly.
Note:
Voltage testers with a low current consumption continue to glow faintly between actuation from the engine control unit (rather than extinguishing completely) and become much brighter when actuated.
End function "03 - Final control diagnosis" by pressing the ◂ key.
Press "06 - End output".
Switch ignition off.
If the LED lamp does not react as described:
Switch ignition off.
Connect the V.A.G 1598/31 test box to wiring harness connectors; the engine control unit should not be connected. Attach the earth clip of test box to earth -arrow-.

Important
To prevent damage to the electronic components, select appropriate measuring range before connecting the measuring cables and observe the test requirements.
Check for open circuit and short to positive or earth in the following wiring connection:
Connector / Contact · Test box V.A.G 1598/31 / Socket

Who makes these pages, and how
TorqFix was built by a mechanic — after a 2,700 km drive with five roadside repairs that no diagnostic tool could explain.
The figures on this page come from manufacturer workshop documentation and are shown as they are. The page is assembled automatically from that data — it is not written by an AI. The AI works in the chat, where it answers for your specific car. It writes nothing here.
Variants of the same model differ. Cross-check torque against the factory manual for your engine before final tightening.
