OMG - Why would they put it at the back of the engine!

Servicing the CATA 3.0L TDI engine's timing chain requires removing a number of components to pull the engine/transmission out of the car and tear down the back of the engine. Labor plus the replacement of more parts (which are also much more expensive than a timing belt) would probably cost around $6000 vs. under $1000 to replace a belt.
