ERLoft Posted February 10, 2014 Share Posted February 10, 2014 In an effort to track down the cause of what is likely false knock being picked up by my knock sensor, I was under the car yesterday tapping away with a rubber mallet. I found that either the drivers side header heatshield or front (center) exhaust pipe section's heatshield has an annoying rattle in it. This may or may not be the cause of the knock sensor issues, but I'd still like to fix it since the noise is annoying. I'm figuring I have three real options here: Have the heat shields removed, welded up to remove any rattles and reinstalled. This may leave them subject to future problems in other areas.Cut off the heat shields (I can't get some of those bolts to break loose even with my DeWalt impact gun) and leave the headers exposed.Cut off the heat shields and wrap the headers with thermal wrap. (Mostly to help keep under hood temps down) I'm looking for opinions on which road to take. Any thoughts? 2013 █S4 - Glacier White - DSG - B&O - Tech Package - Sports Diff - Napa - RS4 Grille - Stasis Exhaust - APR Intake - KW Variant 1 - Stern Control Arms - CR-15 - Stasis RSB - Moog Endlinks - PC Hyper Black Peelers - Deval Front Lip - ECS Rear Diffuser - Carbon Imports Ducktail - ECS Mirror Caps - Relak Paddle Extensions - Autostyle Floor Mats - LED Interior - V1 - Blackvue DR900s - [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
