Silly question

[jatint]

This is a silly question but hopefully someone can help me

I have a vectra C 2006 1.9 cdti facelift

Is it a 16valve or 8 valve?

The two engines have the oil filler cap in different places - whereabouts is yours located on the engine cover?

Right hand side middle

One of the easiest way to find out is by the colour of the CDTi badge on the boot. If its Red then its the 150bhp version. Of course the previous owner could have changed badges!

I'm sure someone will be along shortly with a more mechanical way of telling!

TI on CDTI is red, its the 150 bhp version im sure but dont know if its 8v or 16v

[Vectralicker]

All 150s are 16v
All 120s are 8v

Ah thank you very much, needed to know to re-map it
New to Vectra's :-)

I had the DTUK green box on my 150cdti and it was amazing
