| Fitting location of the hall sender → Chapter. |
| Special tools and workshop equipment required |
| t
| Handheld multimeter, e.g. -V.A.G 1526 A - |
| t
| Measuring tool set -V.A.G 1594 A - |
| t
| Test box -V.A.G 1598/22- |
Note | t
| The hall sender is located below the camshaft wheel. |
| t
| If the hall sender signal fails the cylinder assignment of the knock sensor signals is no longer possible, therefore the knock control is deactivated and the ignition angle is slightly reduced to avoid knocking effects. |
| t
| If the hall sender signal fails the engine keeps running and can also be started again because of the following reasons: |
| t
| There is no noticeable effect on the injection if there is a displacement of an engine revolution. |
| t
| Instead of occurring with the injection valve open the injection occurs pre-engaged (before the closed injection valve). This only has a very slight influence on the quality of the mixture formation. |
| t
| For the dual spark ignition system, an ignition spark is present for each engine revolution per cylinder and not only as usual for each second engine revolution. |
