Unusually, the 'D' stands for direct rather than diesel. Mitsubishi beat them to it with their GDi (as used in the Carisma) but Renault's IDE was the first direct injection petrol engine from a mainstream European manufacturer. The fuel is squirted straight into each cylinder, as opposed to into the intake manifold. This supposedly results in both better performance and economy, but is a bit of a nightmare to control properly from the ECU 's point of view.

Apparently the 2.0 IDE started out life in the Megane Coupe before finding its way into the 2.0 Laguna II. In the Laguna, it was replaced with the slightly less powerful 2.0 VVT engine in mid 2002 due to the reliability problems that Webcode mentioned.

Having had one, I can say that the IDE is a great engine when it's running right. It's surprisingly torquey for a 16v petrol engine, so while it doesn't need to be thrashed hard for decent performance, it can handle a good thrashing too when you really want the most of it. In that respect, it's like having your cake and eating it. It's a shame about the reliability issues, because if it was actually good for the 100K+ you'd expect out of a modern petrol engine, it'd be an excellent buy. As it is, they often need serious work or even replacement at around half that mileage.

Ahh! I should have read the ad more closely! It was the D in Ide that threw me. the car has been sold anyway now, so someone else will find out the hard way. Ta for the feedback, I think I'll stick to the 1.8 for now!

I note with interest that the 1.8 16v F4P engine was recently dropped from the Laguna line up..

Is this engine also ( in your experience ) unrealiable..

Mines at 115k with no problems and pulls well with the K+N I always swear by but wondered what others think ?

I find the 1.8 engine to be Ok, but a bit unrefined at certain points in the rev range. The low down torque can be lacking and careful use of the clutch and throttle are needed in some situations. Hovever overall for a big family car the 1.8 does extremly well, with no mech probs so far (I have had the car for a year now). I read your post on the K&N filter with intrest - do you need to inform your insurance co when fitting one? - I don't suppose it would make much difference as it is not a drastic mod?
