The next eight weeks or so will some of the most chaotic we have. We do everything we can to keep on schedule, we know you need your vehicle back.

That being said, we will pause all current work loads to address issues with an emergency vehicle. We have yet to find a case where a PD, FD, DPW, or similar had a supply of spare vehicles. Please understand this will affect our completion date for your vehicle.

We appreciate your understanding.

Yeah, we can work on that too…

AC work - it’s that time of the year!

This ambulance had evidence of an AC leak, here we are testing the system with nitrogen and soapy water.

Don’t worry - the ambulance is back in service!

This is why diagnostics matter.

This is a 2012 VW, the vehicle would randomly die, and may or may not restart. It had a P0087 (low pressure code) and the aftermarket dealer put a new high pressure pump in it, didn’t resolve the issue.

There is a low pressure pump in the tank which pushes fuel to the high-pressure pump after the high-pressure pump is the fuel pressure sensor, if either pump failed, it would still set the same code.

What you’re looking at in the picture is an induction clamp around the feed wire for the low pressure pump (the picture is after repair).

VW states it should draw around 8 amps, when the test was done before repair, it started at 9 1/2 and after 30 minutes was over 14 amps. The fuel pump driver (the little silver box) shut off the circuit to protect it from being overloaded.

Long story short, it means the low pressure fuel pump was dying, it would draw more amperage than the driver module would allow and the module would shut it off inducing the low pressure code. There was likely nothing wrong with the original high-pressure pump. 

The icing on the cake? The high-pressure pump cost more money alone than the low pressure pump, labor to change it, and the diagnostics…
