Aircon saga, round 2

David Allen contributed a useful RV8NOTE378 in June 2013 based on his experience of having his aircon system checked and recharged by Kwikfit. Here he provides an update. (Jun 2014)

Here is round 2 of my aircon saga. After having it was recharged last May 2013 it had stopped working again in August by the end of the European Event of the Year at Aviemore in Scotland. I left things alone through the winter but as I am now preparing for the EEOTY in Denmark I went back to Kwikfit. Once again I was most impressed by the quality of the people and the reception I received there. The price of the Kwikfit refill still £49.

I watched the procedure right through. The aircon system has been charged again after going through the full test procedure successfully. There were still some 150g of the coolant left out of a charge of 1250g so the leak was only minor. I was advised that their machine is not good enough to check for pinhole leaks but that they now put a ultra violet or UV dye into the system to check for aircon system leaks these. We put the car on a ramp and with UV glasses and a UV torch could see a very small telltale leak on the balance pipe that connects the two condensers underneath the front bumper. There was evidence
that it has been hit by a stone sometime although the rubber sleeve is intact and a small dent in the pipe could be felt.

We will go to EEOTY in Denmark and report back. On the assumption that it has leaked again, the Kwikfit technician said he is fully up to speed with aircon repairs so I will have the whole system looked at by him. Hopefully a simple balance pipe will not be too expensive to repair.

Still a great fan of Kwikfit.

Photo of the fault on the balance pipe? David responded saying "the telltale was so small as to be unphotographable and only visible through special UV filter glasses".
