Never noticed the light on while driving. The 'new' gp's are German, but not Bosch. I'm going to have them all replaced I think. They offered to swap them for a better brand... Spray pattern could be bad, though. Never noticed any hint of a problem with the ignition switch - nor do I want to. I'll try the relay and go from there. BillR

I'm confused. The GP's are only a few months old and you've already lost three of them? (Are they Monarks? :-) It sounds like your GP relay might be powering the GP's when the engine is running, or you have very bad injector spray patterns. A flakey ignition switch can trigger the GP relay to go on when you're driving, accelerating GP wear. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
