compressor problems

Ok having a few issues at the moment one is car lowering overnight after fitting new shocks and i had a hole in my reservoir tank, i fixed the hole last night and started the car this morning hole in tank fixed there is however a tiny leak from the front of the drier cap on the compressor some blue tack sorted that as a temporary fix whilst i sprayed soapy water to find any other leaks but none were found however and this is my problem i was expecting the compresor to run longer this morning as i vented the reservoir tank to fix the hole but what i noticed was the compressor would work upto 131 deg c 1601kpa then it would turn off the exhaust would vent and the preasure would stay stable at 306 kpa then once the compressor temperature got down to 108 deg c it would start up run upto 131 deg c 1600-1700 kpa shut down vent to 306 kpa this just kept happening once down to 108 deg c it would start then stop at 131 deg i know this isnt right any ideas.

Just remembered there are no warnings or suspension faults logged in the morning the car can take slightly longer to raise from access but the rest of the day all is fine

AFAIK the suspension pressure is about 16 bar. Mine does similar things so I just bought a service kit for the compressor as it's taking a long time to get Up to pressure and I'm getting a venting fault after driving for a few hours. Mine also drops down to about 4.5 bar and waits for the compressor to cool before it re pressurises again. I think that I need to sort out the dryer chamber and the delivery valve.

ive fitted a newer compressor with new drier beads but just wanted to work out what the actual working pressure is and what would be causing the compressor to kick in so much but before then i have to sort out the sinking suspension
