I have had my eye on the touareg for several years. I finally found a pristine 2011, hybrid, which i love. I have 2 concerns. That annoying flutter from the timing chain on cold start. It only does it once, when cold, and goes away as soon as pressure is up. Is this common??? Also, i think the hybrid battery is getting weak, low after parked several days, but comes up quickly after driving a short distance. Is this normal?? I have figured out, the electric motor is secondary, adding needed power to assist the gas engine, not primary, as in a prius. So, i dont see this as a serious problem. It has good power, no lights. Beautiful car, drives better than my infinity. I think there is a tensioner for the upper chain that is not so difficult to replace. Any advice is welcome.
