Seems like a clog/kink somewhere in the lines. Also, was the coolant properly cleared of air bubbles? You activate the pump with the engine off using a certain pedal sequence, not by running the engine with the cap open like you do with mechanical pumps.

I will have to ask the mechanics about this. Thank you for the information. I will look into this for sure

The mechanic seems to believe that there are deeper issues with the car that might have caused the first water pump to start leaking in the first place. Any ideas what these issues could be? The system has apparently been running at high pressures and very hot since the time that I initially brought it in to get it's water pump checked for the first time. Things have escalated from here after the pump and thermostat were replaced.... Definitely sounds like a kink in the lines is possible - causing the high pressure and sudden fluctuations in oil temperature whenever the kink loosens itself and then kinks back up again

Have you guys checked the radiator? Also check if your fan is working. Check fuses.

You might want to check that the tech did the proper coolant system purge protocol, which can be done without a factory tool. I'm sure you can find the process here on the forum.

These are all great ideas, thank you! I just emailed the shop to have them check all of these things out. The OFHG might very well be the cause if it is not a failed thermostat.

I noticed that when I picked the car up from the shop after the pump was changed that the OCI had dropped from 7000 to 2500 miles which I thought was strange but I also thought that the shop had calculated this change. I believe that the car sensed something was jacked with the fluid.

Hopefully I'll hear back soon from the shop and can report on whats going on.

Heard back from the mechanic. Was informed that the DME was melted. Hoping that replacing it will solve all of the issues.

oogabooga · 10-30-2014, 11:07 AM

I have no idea. Some sort of a short probably?

oogabooga · 11-06-2014, 05:11 PM

Just an update. DME was melted so now the engine has to be pulled to figure out what is going on with the engine harness that caused the short

Mutagen · 11-07-2014, 01:27 AM

Wtf that suks man. i hope it's the right diagnosis.

My car is a 12/2007 build. I am hoping this shop figures things out quick. I am getting a new DME and engine harness so hopefully that fixes things...
