Last time I posted it was October 13th and it was about HID "tricks" on the 07 GT. I posted a lot of pictures, but you might have noticed there wasn't one with the HID headlamp on. Why you might ask? Well the reason was, I couldn't get the bike started. Battery problems? No, at that time it had a 2 day old Odyssey PC680MJ.
Then what was the problem? It cranked like a son of a gun but just wouldn't fire. Not even close. I stopped short of burning anything up and then tried again the next day - same story. Next day, same story. Yadda Yadda.
I called the dealer and made an appointment for my annual & level 1 service (22k) and noted the bike wouldn't start and could they pick it up? Sure. Also, I complained that the timing chain had been sounding like shit on cold startup for a year and was assured they would replace the tensioner with the new reservoir type under warranty.
I also confirmed they would change the fluid on the FD.
The morning they were going to arrive for the pickup, I went out to the garage and tried to start it one last time. For once it actually started, but Holy crap, the racket it created made such a noise I had never heard, I shut it down within 3 seconds.
When the van driver arrived he asked if he could try and start it, and I said NO WAY. I asked that it be haul in as-is and once in to the shop they as a group could testify what was wrong after they had it there. He agreed.
By the time I drove the cage to the dealer and walked to their service bay, the bike was already out of the van. As I walked in I asked "did you guys try and start it"? They said "yes, but it wouldn't start and something is definitely wrong with it". We got all the other service agreements set in place, I signed an estimate that the work on the bike would be around $1K (damn valve check), and they had written up that the tensioner would be changed under warranty.
This afternoon I went to pick up the GT. I was "happy" the bill was only $710 including 4 $22 spark plugs. The service tech explained that they had to "retime" the engine by moving the chain back (or forward) a whole link
. He thought the chain had jumped a whole tooth and that is why the engine wasn't starting.
Lesson learned? Pay attention to your older chain tensioner issues. I've learned the hard way it has the possibility of being more than just a noisy inconvenience. Don't take the "they all do that" as an answer to your complaint. BMW wouldn't have redesigned the whole mechanism if there wasn't a recognized engineering problem. I'm happy with my dealer, and I'm happy it was fixed under warranty. I'm just disappointed that BMW didn't make the chain tensioner issue into a voluntary "recall" situation or at least a written notice to owners so I could have avoided my situation. Also, I have noted the dealers comments about "chain skipping" so if I have future problems with the chain or gear teeth, it is documented what happened.
