Thanks in advance. There are several things to check: Check the rear door seal, and the adjustment of the rear door. Check the 2 lower seals where the heat exchangers connect to the muffler. If those leak, they will blow fumes forward into the heat exchanger jacket, and even if you think the heat is turned off, some may get inside. Check the charging system voltage. It should be above 13.5V at med rpm and a warm engine. If it is lower than that, the FI will run rich and that really aggravates any other problems, as well as giving poor power, poor gas mileage, and excessive engine wear. -- ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
