Make sure you have fluid in the reservoir before taking it to the dealers, if there's a leak and it runs out it could be nasty , tell them you've run out of brakes and they'll come to you

Did you get a resolution to this?
I have reported the same issue basically since new. Each time they simply bleed the system and all is good for another few months until long pedal is evident again. A quick touch prior to braking gets it back up again. They have checked the booster for oil contamination and found nothing. On one occasion I opened the reservoir cap and pedal came back to normal. Service manager has noted that there is obviously air getting in the system over time and will continue to investigate. I noticed the other day, dust accumulation around the calipers, but after three years I would have expected such. At the very least make sure you keep reporting it so it is on your record.
yep , thinking it might be coincidental that its the removal of cap when they bleed it that makes it ok again for a while until vacuum builds , the breather on the cap could be blocked, giving you the symptoms, I did spell Mungus but auto correct auto wrecked[tonguewink]
Wow, what a difference having brakes makes. Dealership ended up doing a manual bleed (?) to all wheels and the brake pedal feel is now nice and firm. Such a difference I can't stop smiling. Maybe it's even a permasmile :)
cheers and thanks all for your input.
