Hi.
Anyone tell me where the Electric vacuum pump is located on the vehicle?
P11B6 Electric Vacuum Pump ESP81? Fault reading. This is preventing the Stop/Start from working, it also will not allow full electric mode to operate ZEV.
So need to repair it it. Can anyone help.

Find your servo follow the vacuum feed pipe back from it it should lead you to the pump

Just for interest I had a look at mine. I can see the brake reservoir but no way can I see the brake servo let alone the vacuum pipe.

Let's refresh this topic a bit.
Does anybody solve problem completely with entering ZEV- electric mode continuously?

I still did not get how that vacuum pump affects on it....

When you running in electric mode there is no brake servo help from combustion engine creating vacuum, hence Peugeot installed electric vacuum pump to make vacuum. If this fails wouldn't have brake assist, hence system disable zev mode....
