Looking for AC/air condition recharging port?
2003 type S 3.0

 

The high-pressure service gauge port valve is located on the tube assembly, condenser to thermostatic expansion valve.

The low pressure service gauge port valve is located on the manifold and tube assembly at the compressor.

If the compressor is being replaced, the desiccant bag must also be replaced and the correct amount of refrigerant added by weight to a maximum of 750 grammes.

 

I've moved your question from General Tech Help to S-Type forum. This is the place to post technical questions about your model.

I replied to an earlier question of yours about sensor location but have no idea if it helped or if you have even seen it......?

The low side port is in behind the drivers side (US) front wheel, the high side is near the top suspension mount on the same side.
