Known issues on the 2018 Q3 Quattro. One recall is on federal record for this model year, covering LED headlight-equipped models: an inoperable front turn signal can fail to alert the driver with a warning indicator, so the driver may turn or change lanes without signaling and raise the risk of a crash. Owners have filed 26 complaints for the year. The factory diagnostic and repair procedures behind that lighting circuit are here.

From tracing a turn-signal fault in the LED headlight circuit to a routine service interval, it keeps you on the OEM procedure and correct specification for your specific 2018 Q3 Quattro.
