Hi guys

I have the 1.9 150 bhp Astra + my partner wants the same car.

Noticed on another thread though that the 1.7 is better. Would just like to know why. I know there better on fuel but what else etc?

way more reliable engine, the 1.9 has lots of common problems, just search around here for instance, sure the 1.9 is more powerful, but will be hit with the big bills like gearbox rebuild, egr valve, swirl flaps etc. I would look at the 1.7, but i have one anyway so I can't talk

I think the 1.9 have a lot of gear box problems? which the 1.7 don't. Am I right?
I think it's the 6 speed box that's the one with problems.
However I'm sure they both have there ups and downs.
I've had a 1.7 for 6 months and have had to replace....
Alternator, Turbo and cambelt lol

Meh, there's no definitive answer

Purely subjective and circumstantial
Agree totally im young so in the words of clarkson i wanted power! Though have had egr issues and a new box dmf and clutch (not cheap) but its hit 100k now and the engine still seems happy im not getting rod anytime soon

The 'engine' on the 1.9 is pretty much bulletproof, just like the one on the 1.7. It is all of the bits that bolt onto it that cause the problems.

Usually the same things go wrong on the 1.7 as the 1.9:-

Alternators, EGR valves, turbos, DMF's, gearboxes, water pumps, management system failures.

The incidence of failure seems to be greater on the 1.9, but in reality I think it is luck of the draw and just as likely to happen on either engine type.

ive had my 1.9 for 4 years and had no problems

i love mine so much even to this day i injoy driving to and from work every day just so i have a reason to drive lol...

i think alot of ppl have the 1.9cdti its probs like 10% that have these problems as most ppl dont post all is well... and alot of ppl post of threads to get help not to say all is well....

its all down to how you drive it and so on. also having 6 gears is just nice lol...

i think both would be great just depends what you like.

4 1/2 years of my 1.9 and no problems whatsoever.

I'd guess the answer to the OP would be... Nothing. The 1.9 has better economy, power, refinement and even sounds less agricultural. (Y)

I have to point out the 1.9 doesn't have more mpg? Lol.
1.9 has more power but worse mpg.

On the motorwat I can get 73mpg over a 200 mile journey from mine to Glasgow.


Last week I did 647 miles to a tank with a range of 9 miles left and got 51.5 litres in. I will put those figures against any 1.7 ;)

yeah, its like going from 1960s massey ferguson to 1990 massey ferguson, they are all massively agricultural :lol:

and the 1.9 8v seems more reliable than the 16v. doesnt the auto only come with the 8v 1.9
