Repair shop thinks it is related to the Secondary Air Injection Pump.

Hello, What code(s) show up when you scan the vehicle? Manual or automatic?

Hi Casey40510! VW is automatic. Haven't had it scanned yet. Repair shop charges over $70 just to get it scanned! I have purchased a scanner (TopDon OBDCan Plus) that requires a Windows PC to download software update. I only have a Macintosh desktop. I also purchased a FIXD unit that attaches to an iPhone. I don't have an iPhone. Just a dumb cell phone. I'm hoping that my Son can come here to use his PC laptop and iPhone to scan for any code(s). Frankly, I find it hard to trust most repair shops, especially when they don't allow customers in the repair area ("Insurance regs!"). So... I'm hoping I can get some codes to study prior to get car fixed. I'm trying to educate myself before spending hundreds on any repair. The latest possible problem was my mention to the repair person at the service desk that when I start the car, I get a very short, quick, squeal lasting a tenth of a second. That noise never happens when engine running. Only once when starting. Repair person says sounds like the Secondary Air Injection Pump. Long story ... sorry. RikMac
