Make sure that the hose from the pressure sensor is actually connected to the intake air distributor; check both ends. Measure the charging system regulating voltage. It should be 14.1-14.4V measured at the battery, with the engine warmed up after a drive, at MEDIUM rpm. If it is below 13.5V replace it with a genuine Bosch. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Too much?
