So... After being a Lurker here for the last couple of weeks searching for answers to my problem, i find myself here. another victim of the swimming PDC.
I first noticed that the PDC was not working a couple of weeks back, it would throw an error every time i started the car. that stopped completely, so after some research i found this post. which is amazingly informative btw! i always thought that the water i could sometimes hear sloshing around in the back, was diesel. when i followed this guide to get to the PDC area, true enough there was a swimming PDC unit, (the other side is fine)
I removed the PDC dried it out, drilled some holes in the plastic bungs so this cannot happen again, i think the water has come in through the light cluster, I've changed the lights in the past, so this must be how it got in.
i also discovered that it can cause wet seats, (true enough the back seats were slightly wet), with water seemly coming from the bolts that hold the seat belts in, but i cant be sure.
what puzzles me to no end, is how do i remove this water, and how did it get there? it seems to be under the seats, inside the frame of the car!?
I've removed 4 bungs from underneath the car, little water came out. still can hear sloshing around. i'm completely stuck and just want to remove the water from the chassis, took the car to a Indi, told me to check in with a body shop because he has no idea.
does anyone have any experience with this at all? - am i missing something after reading this thread over and over?
p.s my PDC unit no longer works, i wonder if its a fuse or its just toast, it didn't look to bad after id dried it out, im having issues finding a replacement on the web. any ideas on that?
Thanks for taking the time to read, and glad to have finally joined this wonderful forum
