Ducati Woes

I own a Ducati Multistrada 1200S which I bought from new in 2010. After a year and a half of trouble free riding the ABS warning light came on last November.

I took it to the Ducati dealer and 6 months and 4 visits later, the bike has not been fixed. Various parts have been replaced on the bike (under warranty) with little or no urgency and each time I pick up the bike the problem still exists.

I am currently waiting (for the past two weeks) for Ducati to think of the next part to replace. I have no useable bike and a European bike trip booked for the end of June.

What should I do?
