Help can anyone tell me what type size etc locking wheel nut or bolt I need for a Octavia 1900 TDI PD Amiente, with 15" Helios alloy wheels. Have searched through Google etc. and asked Skoda and dealer no reply yet.

mk2 elegance on 16" wheels comes with a locking nut on each wheel and is supplied with a special "key" to fit the wheel nut spanner.

I beleive there is a large number of nut & "key" combinations (50+) - mine has a number stamped on it, an it is recommended to store this number in a safe place
