I'm not sure if there is one for the Edition 30. I've got one of these for sale but they brought a revised version out which includes Golf models up to 2008.
According to the Haynes website, even the revised one doesn't cover the Edition 30. Taken from Haynes website..
Exclusions: Does NOT cover GTi 30, GTi Pirelli, R32 or 4-Motion models. Does NOT cover 1.4 litre TSi supercharged/turbo (Twincharger) or 2.0 litre chain drive petrol engines or 1.6 litre Fuelflex engine. Does NOT cover 1.6 litre TDi diesel engine.However, according to Halfords..
Vehicles covered in this Haynes Manual
Golf / Golf Plus ('Mk V') Hatchback including special/limited editions from August 2004 to September 2008
Jetta Saloon including special/limited editions from August 2006 to 2009 (55 to 07 reg)
Petrol: 1.4 litre (1390 cc), 1.6 litre (1595cc & 1598 cc) & 2.0 litre (1984 cc), inc. turbo
Diesel: 1.9 litre (1896 cc) & 2.0 litre (1968 cc), inc. turbo
Does NOT cover the R32, 4-Motion , Estate models, 1.6 litre TDi engine or 1.4 litre TSi supercharged/turbo engine.Your guess is as good as mine. Maybe an Ed30 owner will come along and help clear things up!
Let me know if mine is of any interest.. Looking for £12 inc p&p.
Cheers.
