2-3-2 fault code long term fuel too rich or weak
I have a recuring 2-3-2 fault code apprearing on my 850T5 this is I believe a long term fuel mixture proplem??? However what is the likley cause and how to fix it. It seems to happen on the overun when slowing for a roundabout for example. I am runnung on 95RON fuel. Interestingly when I was in france last month using 98RON (only a cent per litre more expensive over there) the fault never occoured over 3000 miles. Anyone any ideas please!

Yes I had exactly the same problem and the vacume line elbow was split where it connects to the inlet manifold behind the power steering pump. I have made a DIY repair. It is really difficult to get to.

Likely vacuum line, but search this forum for other ideas it's been covered many many times before.
