It's well into a/c season here in Texas and I've noticed the unit in the
TDI is getting a little weak. That is, however, one area of
mechanicking that I've not delved into much.
As best I can tell, the manual specs are for 203 psi on the high side
and 17 psi on the low whilst running at high cool. I borrowed some of
Dad's time and gauges and we found 155 on the high side and 40 on the
low side. Sadly, there's no sight glass. We looked hard and with all
the time I've spent in the engine bay of this car, I would have found
it. Believe me. The a/c's still dropping out on me after a while.
Good to start and after 40 minutes or so, not as cool anymore. I'd
assumed it was the evaporator freezing up because of low coolant, but
adding coolant barely changed the readings and the sweating in the seat
Any thoughts? I'm ignorant enough about a/c that I don't even know what
questions to ask.
