We purchased a used 2012 Q7 TDI with 61k miles about two months ago. Everything was running well until we had the windshield replaced. Since then, I have had repeated wiper malfunction indicators. First time it happened, I double checked that everything was securely connected. Indicator would go away for a couple days only to return again. Yesterday I ran a complete scan on VCDS and found five fault codes. I should also mention that since the replacement of the windshield the blow motor has also been intermittent, which I find odd and probably just coincidental. Below are the faults that we found with the scan. Any help would be greatly appreciated.

I'm not an expert but others may come along. Two possibilities immediately come to mind:

1. Water intrusion, possibly related to the windshield installation, is causing electrical problems somewhere. I'd check the firewall area and carpet for moisture, maybe a missing/incorrectly installed cowl or cover, etc.

2. Low battery can cause all kinds of electrical faults, but usually there are more than you have listed.

Good luck!
