Hi,

Recently bought a 2011 B8 2.0tdi 143bhp auto, cars on 135k, I have checked at tos that i have a 100mm hex key fitted. I have read various threads regarding the 77mm hex key and the oil pump failures.

Is it advised to get a new hardened balancer shaft with new key as a preventive measure, or just keep the OEM one as it is.

First Audi so excuse all the questions.

Thanks

All the oil pump failures I've heard of have been on the b7 and really early b8s never heard of any on say 2010 onwards.
