TDI Timing Checker ’Plug-In’ for <strong>VCDS</strong> - Section 33-A<br />
The TDI Timing Checker is automatically installed when you install <strong>VCDS</strong>.<br />
Note: This ONLY applies to VE Engines and DOES NOT<br />
apply to PD (unit injectors) or CR (common Rail) engines<br />
This plug-in allows you to check the injection timing setting on a VE TDI engine (NOT PD or<br />
CR varieties). This needs to be done after you change the timing belt and should be done<br />
every once in a while to keep tabs on belt stretch and pump/pulley misalignment. The<br />
standard procedure for this is to have the engine idling at operating temperature (coolant<br />
temp >85*C), go to measuring block 000 for the engine, switch to basic settings and report<br />
fields #2 (injection timing) and #9 (fuel temperature) on a special graph.<br />
This plug-in reports the timing on the graph in real-time, so you don't need to have your<br />
manual sitting on your lap at the same time. The application also gives you a comment in<br />
the "result" field, that will tell you if all the conditions are fulfilled to check the timing (some<br />
people don't realize you need to have the engine running, for instance...) and if your timing<br />
is within spec or not.<br />
The history of the last 100 samples is displayed as a "cloud" of points. From the size and<br />
shape of this "cloud" you can see how much "jumping around" your engine is doing, and<br />
your average timing is probably right in the middle of the cloud.
