2019 A5 - Pump C Fault ( P26F4 )

[Thomson_adam]

Hello Everybody
I have been having a few issues with my 2019 190bhp Audi A5 with 108k on the clock m.

I have recently had the car remapped and after picking it up the EML came on. The mappers checked the code and it was pump C open circuit. They flashed the car back to stock incase it was a map issue and it came straight back on.

It does seem like a massive coincidence but they are telling me it’s not the map that’s causing the issue.

My code reader is giving me a couple of codes
P26F4 and P26F5

First of all , where is pump C ? And can I drive it with the issue until my garage can get me in to look at it.

No way will it be the map and it is a common problem, what is the VIN?
