So, the Christmas works in lovely Tier 4 Essex.
First up was just a straight forward oil service, no issues and the oil removed was still pretty clean.
Secondly was a job I had been putting off, investigating a very very slight coolant leak (approx 1cm drop in the expansion tank in approx 3 months) and the occasional slight smell of coolant in the cabin. I have so far been unable to find a leak in the engine bay so put it done to a weep on the matrix.
So I set about removing the dash and heater box. Not such a difficult job, but quite time consuming if you take care not to break anything. Unfortunately my efforts were somewhat wasted when I removed a prefect condition matrix. I confirmed this with a pressure test and it was holding a solid 18PSI with zero leaks. Somewhat frustrated I decided to at least give all the wiring a tidy up with some fresh fabric loom tape and added some foam in areas to cut down on squeaks & rattles. I also cleaned and renewed the foam seals on the heater box with some new high density foam strips. Since fitting my Recaros the rear HVAC tubes were removed so the heater box was venting into the centre console. As this is less than ideal I blanked off these apertures with some foil backed kevlar heat sheet. The foil sheet was also useful for sealing the ducting better to hopefully make the whole system more efficient.
It was nice to be able to clean all the dash pieces properly before refitting, I even polished the scratches from the ignition barrel.
Refitted and filled with fresh Type D coolant I bled the system, however I have since found one small issue. The stepper motor for the temperature control is not recieving either power or signal from the climate control unit. The stepper motor I have tested and functions perfectly so this could well be a broken or damaged wire I will have to investigate.
So frustratingly it was a lot of work with an unexpected outcome and now a new fault to find and fix. However a small road test has proven my work on refitting the dash is now resulting in zero squeaks or rattles, so that’s an improvement at least.
