Hi! I haven't had any more problems with mine, but I'm not sure what the reason is. It has gotten a little bit milder temperatures, but I have still had -10 an even some more.Has anybody made any progress in finding cause and solution for this yet?
I’m not saying it’s this or that, but I’ve asked several workshops if they can refill the system with nitrogen and all of them have asked what I’m talking about.If you have a 7P 2011-2018 it is a closed system that has originally been filled with nitrogen. If needed it will refill itself with atmospheric air and over the course of 10 years it might be that most of the nitrogen has been replaced with air.
aha! Great info, thanks! How can double check for sure that I have the 7p? And what is this self study programme?Overview of components
For the first time, the air suspension system on the Touareg 2011 is a closed system. The closed system has the following advantages compared with the open system:
● Reduction of the storage volume required for the air system
● Air exchanged only between air spring dampers and pressure accumulator during normal regulation
● Clearly lower pressure difference during regulation
● Use of a smaller compressor that weighs less, runs quieter and consumes less power
