I feel your pain mate, my local Jeep service dept didn't know it existed.
After sitting in his office for 5 mins looking on his computer for it, he gave up and actually asked ME to go away and find the TSB number for HIM and when I had it to email him the details.
As far as I could tell he didn't believe me and was just trying to fob me off.
So I rang the dealership in the city where I bought the car and 60 seconds later the guy at Wanneroo Jeep is telling me everything I needed.
I couldn't write it down fast enough
Now as you say it's a waiting game!
