The last time this came on I drove for around 1 hour and it cleared. It came back on again, so I decided to take it to the dealer. They had it over the weekend and told me this morning that the turbo needs to be cleaned. They also said they don't have the capability to do this and referred me to another dealer. From what I have researched in the forum, I am thinking this is common with these vehicles (even though it is a pain) - is it common? How bad is it? Am I in for a shock with this rig? Thanks!
