I have replaced the camshaft tensioner, camshaft chain and camshaft position sensor on my 1.8T Passat and now engine stalls when temperature reach normal position. Is there a way to activate tensioner's solenoid with my VCDS? In the repair manual it is written to check activation of the solenoid valve for camshaft adjustment via the Output Diagnostic test mode (function 03) and an editor's note that reads: Component activation is accomplished using Volkswagen diagnostic scan tool, output diagnostic test mode (function 03). When reading the display in function 04 I do see the tensioner's status and when I put the cursor on "Test OFF" a message appears that activation is not ok???Here is the last scan I did after the engine stalling:

Code:
Chassis Type: 3B (3B - VW Passat B5 (1997 > 2005))
Scan: 01 02 03 08 15 16 17 19 35 36 37 46 47 55 56 57 58 75 76 77

Hi and welcome.

IMO, you need to fix whatever is ailing the Engine Speed Sensor (G28) signal first. That's the most important sensor on the engine.

Your ECU does support Output Tests, but only "Sequential" not "Selective", so you'll need to work through the sequence until you get to the right test. The sequence is determined by the ECU itself, so I have no way to tell you where in the sequence the test you're looking for will be.

Hey Uwe,

Thank you for your quick reply. I replaced the engine speed sensor as recommended and guess what, the engine doesn't stall after it warms up! It was idling a little rough after it warmed up and the check engine light came on, but scanned and erased the fault and then took it for a test drive for 16 km. Runs really well and lots of pep and engine restarts immediately and no more check engine.

Also did the sequential output tests and did see the tensioner in the auto sequence but still reads "off" and "activation not ok"???

Here is the scan I got after check engine light came on:

Code:
Chassis Type: 3B (3B - VW Passat B5 (1997 > 2005))
Scan: 01 02 03 08 15 16 17 19 35 36 37 46 47 55 56 57 58 75 76 77
