I just thought I would mention I received an e-mail regarding my new DZ200cdi.
It seems mine was assembled with a pair of bolts in the throttle body that were 32mm long instead of 35mm long. I'd guess that any affected customers would have already been notified like I was, but if you've bought one very recently it might be something to check next time those two bolts are out.
The overall length of my bolts are 35mm (including head) but the shank/thread is only 32mm resulting in only a few threads being engaged. Easy mistake for somebody at the bolt factory to make I suppose??
