Default Engine light on


Havenít been on for a while- havenít needed to! My 57 plate 4.2 diesel has been amazing for the past 40k miles (now showing 215k).

However the engine light keeps coming on.

Vcds shows

Fault codes
Throttle body module 2
Electrical malfunction

Battery regulation
Upper limit exceeded intermittent

Are they related? Do I need to sort the voltage regulator or the throttle body?

On vcds charge shows 14.8v, battery 14.5v, condition 100%

Can you offer any advice? Car drives fine as always.
