PTU is a common cause. Joe mentioned a few possible causes in a recent post: Twin turbo advice

Depends on how it’s not working.

Kinda working, but jumpy or reading much lower than it should? Replace the 2 10uF 25v electrolytic capacitors on the circuit board behind the tachometer.

Not working at all? Could be the capacitors, and/or damage to the circuit board caused by corrosion from leaked capacitor fluid. Also possibly the PTU, or the “tach” wire/connections between the PTU and the gauge cluster.

Thanks Matt, I am in the process of ordering one of Joe
