VW oil problem

Happy Wednesday everyone. As I am writing this, I am still trying to wrap my head around the fact that Christmas is next week. That means this will most likely be the last volume of Shop Shots of the year. I know that you are probably weeping. Don’t worry Shop Shots is not going anywhere. In fact next year should be the biggest year yet for all of us. Let’s get to it.

VW oil problemThe story behind this picture is one of those “you have to be kidding me” moments. A customer stopped by the dealer. He was driving through and the check engine light came on in his 2012 Passat. We worked him in because he was just passing through. When I pulled the car in the shop, it sounded a little funny. I started scanning the car for faults. While the scan tool was doing it’s thing, I popped the hook to have a look.

With the hood up, I found the reason the check engine light was on. It turns out the customer had his car serviced before his road trip. He made it 900 some miles before the check engine light came on. The place that serviced his car did not put the oil cap back on. Luckily it was just sitting by the wipers. The car’s ECM had faults stored for an air leak. Leaving the oil cap off creates a pretty good sized air leak. 🙂 I am just shocked he made it so far before the check engine light came on.

Clogged VW cooling systemNext up is a common issue that is taken to a level I have never seen. This is a shot of a coolant bottle on a 2003 Passat. I have seen quite a few 1998-2005 Passats have issues with cooling systems getting clogged up. It usually comes in with a “My heat does not work” complaint. Over time coolant breaks down and starts to block up the system. This prevents coolant from properly flowing in the system.

In this picture you can see just how clogged up the system got. This is a shot down into the coolant reservoir. I am pretty sure I have not seen a system this clogged. The customer declined making an repairs. I think it was a good choice on her part.

VW seat wiring problemLast up we have a VW wiring problem. This one was a good one. The customer complained about the seat moving while driving. He said that sometimes the seat would move forward or back all by itself. It car has power seats. The car had been in 2 other times for the same issue. We were never able to duplicate the issue. But the car had a fault stored in the computer that controls the seat. We had replaced the seat memory buttons, and the module. I pulled the seat out to inspect the wiring. Hidden in the seat rail was a wire that had a been grounding against the frame. Basically the car was seeing the button being pushed. Kind of funny really. I guess this is one of the electrical demons everyone talks about.

Well, that wraps it up for the final Shop Shots of 2013. I really do love posting Shop Shots. It is the most fun for me. If you like Shop Shot, please sign up for email updates. It is the best way to be sure you get all the blog updates.
