2006-2007 Touareg with V10 Diesel, Glow Plug DTCs
If Glow Plug DTCs are present while performing a PDI, check the state of charge on BOTH of the batteries. If the auxiliary battery (in the rear) is low on charge, it can set Glow Plug DTCs because this is the battery that powers them up during start-up. See Technical Bulletin 27-07-02 for battery testing information.
Vehicles with TDI Pumpe Duse Engine, Glow Plug Checking
Do NOT test the glow plugs on these engines by applying battery voltage to see if they glow. They will become damaged or non–functioning in a very short period of time. The correct checking procedure is in Service Net, under the tab in Additional Information
Vehicles with TDI Engine, Glow Plug Relay Clicking On
Under certain conditions you may hear the Glow Plug Relay J52 clicking on and off after the engine is started. Once the engine is started, the after glow period could last up to 3 minutes or until the engine coolant reaches a temperature of 60 degrees Celsius and the engine RPMs are below 2500. Under these conditions you may hear the relay clicking on and off while shifting. This is because the RPMs are going above and below 2,500 rpm. Relay location is in the plenum near the wiper motor
TDI Glow Plugs
Be aware that there are 2 suppliers for the TDI glow plugs-Bosch and Beru. When replacing the glow plugs make sure that you do not mix stock. The vehicle must have all the same supplier or DTC P0380 (Glow Plug Monitoring) may set.
All TDI Diesels, Glow Plug Relay Test
Prior to replacing the glow plug relay (038 911 253) perform the following test. 1) Disconnect the coolant temp sensor. 2) Turn ignition on. 3) Wait 20 seconds for glow plugs light to go out. 4) Using the VAG 1551 read the fault code. If DTC 00522 appears, the glow plug relay is OK. If DTC 00522 and DTC 01050 appear, the glow plug relay is defective and needs to be replaced
