Hi All,

My car has about 115K miles. The car runs great but when the weather gets warmer than 80 degrees the cars starts to detonate when I accelerate. There are no fault codes or anything.

Does anyone have this problem and/or solution? I'm wondering if I need to replace the knock sensor. Thanks

Are you getting really getting detonation as in a pinging sound or a misfire - either way it might be worth checking spark plugs and coilpacks before replacing a sensor. Are there any codes showing - they can still be recorded, without a MIL indication

I'm getting a pinging sound when put load on the motor. I've been driving 10 to 1 compression VW motors forever and I'm getting same exact pinging sound. I've already changes the coil packs and spark plugs. No indicator light and I checked for codes and I'm not getting anything. Thanks

Lets just say I do replace to test. Would I be cheaping out if I go used? $6 to test isn't bad if it works. https://turbobuyer.com/itm/19S443-EN...-/152646062842
