DF1012 = cruise control switched off ( now showing a fault because of DF998, the DF1012 Fault will clear once the other fault is sorted )
DF998 = Turbine upstream pressure fault, either a split pipe, or a Faulty sensor

There could be a small rubber pipe split, just below where the exhaust temp sensor is, also another sensor lower down, on the exhaust pipe..

I had same fault with my car yesterday (1.5 dci engine ) df998 & df1012 fault code . I found the rubber hose which connects the boost sensor and pipe to the exhaust manifold to be at fault . Once replaced and fault cleared down and road tested was all fine . The boost sensor is located to the n/s at the back of the cylinder head on a bracket . I hope this helps
