Ptu

Yes sounds like the PTU is faulty.

They usually fail when hot and often work again when cooled down.

There's a series 2 part that doesn't fail but don't buy it from Nissan they want about £400 for it!

WITH SOUNDIN DUMB WATS A PTU?cars still under warrenty reckon it would be a good idea to get em to fix it?

PTU - Power Transistor Unit, aka ignition amplifier. Its on the drivers side cam cover, rectangular metal box with heatsink fins on and a connector either end. It drives the coilpacks which in turn drive the spark plugs.

 

Try and get it fixed under warranty, at very least they should replace it with a series 1 (unreliable) but push for a series 2 if you can...

 

Bloody typical, USA got a recall on this and all were replaced, UK as usuall get the privilidge of staring to the skies to see the Nissan rectum shitting on them.....

cheers mate really appreciate it il get it sorted
