Hi,

I had the EML light come on my C7 RS6 Performance with the following codes:

P2096- Post catalyst fuel trim system bank 1 too lean.
P16BA- Coolant pump for charge pressure cooler dry running

Any ideas where I should start? Any help would be really appreciated. Many thanks!

Hello, have you tried delete them? And see if they come back?

I've had P2096.

Only that code with nothing else so i will be putting on a new post cat lambda on that bank. from some research it does seem a common item to fail

Have you solved coolant problem code?

P2096 I have already for years, just delete it and go no harm. I have that code popping from time to time when going on low rpms, but been deleting it and deleting. No change in performance

I have since replaced the lambda and put a new set of spark plugs in.

Will see how it goes. Car is running very nice.

Thanks for update
