New owner and tyre pressure issue

[Jimbo1980]

Hi all,

 

Picked up a 65 plate A1 S line TDI at the weekend, very pleased with it overall but suddenly got a warning about loss of pressure in rear passenger side tyre. No problem, looked up the correct tyre pressure online and the general consensus seems to be 29 PSI for rear. Attached my air compressor and it's showing 42 PSI! Seems a bit excessive? Also, if it's already over inflated why would it be showing loss of pressure?

 

Any and all help greatly appreciated.

Hello James,

Just a couple of points:- In my experience, the only place to go for information about recommended tyre pressures ( if  not shown inside the fuel filler flap etc.) is the vehicle handbook, checking against wheel and tyre size, and number of passengers etc. 

Over inflation and tyre pressure warning? Good question. Does this system alert to over inflation as well as under? If not, it should do. 

Kind regards,

Gareth.
