Hi,I'm new here and i have a some questions for you lads.
I'm looking to buy a newish Megane 1.5dci(had the older model but a petrol one),looking at the 2006-2007-2008 ones,the face-lift model. Apparently they have better electrics,is this true?
I read so many bad things about the Delphi diesel pumps,so I'd like to avoid them,and they said the 100 bhp and 106 bhp models have got different,better pumps,turbos,pistons,is this true?
Delphi pumps,I read,suffer because of the lack of sulphur in the new euro5 fuel.
Than the tax bracket at the 106 bhp models could be different,some of them are 30 pounds/year and some are 100 pounds/year,why?
So are the 106 bhp better quality than the 100,86 and 80 models?Are the 106 more reliable?

Re: dci-80/86/100/106

The 100 and above does have stronger pistons to stop the higher injection pressure from scouring them and a variable geometry turbo , something like different tire sizes can push a car into the next tax group the Delphi pump was supposedly updated after 2006 but I would pref not to have one, other than that I don't have a clue.

Who would design a vehicle that falls over when you stop?

If you find a fix for your problem please let us know it will help others.

Tax is calculated on CO2 emissions. Even on the same car with the same engine, different levels of trim will affect the weight, and, yes, tyres can make a difference. The tax bands are quite narrow so it doesn't take much to tip it over the edge into the next band.

Re: dci-80/86/100/106

There are some threads here about the differences between the different 1.5dci power and to some extent torque levels,if you do a few searches.

Aside from the cooler non cooler ,different intercooler and turbo sizes:

1.5 dci engines 85/88bhp and above have redesigned piston crowns to accomodate the higher fuel pressures.
Fap /DPF particle filter engines amd engines of a higherpower may have lower compression ratios than those of a lower power.,Yeh strange but true according to the published figures.
Something less publicised,since you ask about the injection system.
!.5 dci megane engines manufactured dec 2010,or later use a newer bosch injection system .

Before that and the vagaries of delphi system doesnt really concern me as mine was made in Jan 2011.

Im not saying nyah nyah or anything,but lots of googling should give you the answers you need and the 1.5dci specs arent as universal as you might think(especially since the 2012 stop/start version).
