If you can get a 90bhp Bosch 307 hdi it is much better as you have no dpf in the exhaust that gets blocked up and essentially have to get mapped out. Also the 90bhp doesnt have a dual mass flywheel to fail.
And the bosch fuel system seems to suffer less from high pressure pump failure than the bosch system which is used in all 306 hdi's.
The 110bhp will have these issues at some point so id get a 90bhp and get it mapped by pro steve to a nice 125-130bhp.
But yes the 307 has more electrical gremlins too, bsi problems for example if it gets a spike which is just a farse really.
