1.8 Petrol vs 1.9 D turbo...

Why has no one mentioned hdi? Good time to pick up a nice one for cheap at the moment as everyone seems to be selling them to get bigger and newer cars. Hdi has next to no reliability issues compared to an xud, only things that really go wrong with them engine wise are lift pump and high pressure pump failures, crank pulley and tappy Injectors. No overheating, no headgasket failure every time you boot it for more than 5 minutes etc etc

Stage 1 map with increased torque can easily see over 50 mpg with power to overtake safely when needed



Hdi ftw if a reliable daily is needed, plus all the phase 3 toys which just make it a nicer place to be

I don't think they are any more reliable tbh, just different things that break!

You've said about the HP and lift pumps, crank pulley and the ticky injectors. But then the sensors on most now are failing, MAF and TPS mostly, but also FPS etc. Whiny/exploding clutch release bearings and slippy clutches after a remap, cats snapping, EGRs stuck open, boost leaks that are near impossible to access.

Granted you shouldn't be blowing rod's through the block, or shooting coolant all over the engine bay like an XUD, but I still wouldn't say the HDi is great for a reliable daily, the majority haven't even had a belt change as they've just been passed around as workhorses every couple of years. There are a few decent examples (just not the ones I owned ) but theres also decent examples of XUDs....its just that they are so few and far between with both engines these days...

Very true, like anything though I guess regular decent servicing is the key, one thing I noticed with hdi is the 12k service intervals which I think is part of the problem on most of the dodgy ones about. Service every 6k and keep on top of problems like the maf sensor etc and it should be OK. If the engine goes on one pretty much every scrap yard in Britain has numerous dw10 engines
