hi ya! Just a thought, but I had the same thing happen about 9 weeks after I brought my little gem! Went to a mate at vw across the road who pluuged it into their machine. he said that the display flashes as a warning that something is possible wrong & requires diagnosing.

Fault present...pressure switch, but not necessarily that. Could of been control panel! Had mine checked by a very good air con guy, & turned out to be compressor, etc!!!!

had it done under used car warranty....after fighting like hell for it.

All sorted now though

. Best to get it checked. You could just be low on gas. Doesn't take a great change in pressure to show up as a fault.
