Evening everyone.

Wondering if anyone had anything like this happen to their 300h?

I started getting this noise today, like high pitched chirp while engine is running and it seems to come from the fuel pump sender unit. Warm or cold start still there but im sure it just appeared today

Tried to tap it and wobble it with hand to see if anythings loose but no.

Car spec is 63 plate is300h 108k miles regulary serviced with genuine stuff, everyday driving, fuel used. Roughly 2 tank fulls of premium between 10 tankfulls of standard petrol.

Oh and im now going trough second tank of bp ultimate petrol.

Thanks in advance
