Hey
I have read quite a few posts regarding the 109 relay problems and the symptoms that go along with it. I have a 2003 Jetta ALH. That has all the classic symptoms of faulty 109 relay. I have changed the 109 relay with 2 others that worked on other cars. No Change. I thought it may be the ECU so I changed that, still no change. When I jump terminals 30 and 87 on the block where the 109 goes The car will start, but if left connected it will kill the battery. Any ideas what to check next. If there is an answer somewhere on this forum can someone post the link.
Thanks.
