Espace 3.0dci

Looking at purchasing a 53 plate Initiale automatic with 50k on the clock.
Any particular problems I need to know about ?

Seen some horror stories about turbos, injectors, intercoolers etc

All cars have these stories but are they warranted for the Espace ?

Re: Espace 3.0dci

Check everything electrical, every button/switch, turn it all on at the same time as well which will load up the alternator. The aircon systems on most Renaults are a weak point to and expensive to fix (expensive on any car, not just Renault). 50k sounds good but double check it's had it's cambelt changed at the correct intervals, they are every 5 years, regardless of mileage which i think is around 120k on that engine, but it will state the interval in the manual/service book. Check how often the oil has been done. My car (53 plate Scenic 1.9Dci) states every 18k but I don't think that's good for the Turbo or engine as a whole so I do the oil and filter every 9k. I think the 3.0dci is one of the better engines fitted to Renaults. Then, check everything electrical works. I know I said it at the start but Renault electrics could be.... erm...... better.

Re: Espace 3.0dci

The 3.0 dci engine is a real can of worms, I personally would look elsewhere, if however you are adamant then the main things to check are ....

Cylinder liners: 3.0 dci's have bonded cylinder liners which are prone to becoming detached and dropping resulting in total engine loss. Do not consider one which has not had this sorted. Renault replaced about half of the engines under warranty, others were sorted by machining the block and fitting flanged liners, however this was never an official recall so not all have been sorted.

High pressure fuel pumps: known for premature failure of the solenoids and seals. Full repair involves replacing the complete fuel rail at circa 3500. Some people have negotiated a contribution from Renault, I had the pump reworked in situ for about 750.

EGR valves. Poor system design leads to premature EGR valve failure. Blanking is the best option but this adds extra stress to the turbo . EGR replacement costs around 1000

Turbo : Variable vein control rings prone to sticking, and main shafts wear causing oil seals to fail. Never good as this leads to the engine running on it's own oil .

Automatic handbrakes prone to breaking cables. Cables alone cannot be changed so your looking at 600-700 repair.

Injectors prone to failure, cost around 1000 a set remanufactured.

All above are common faults on the 3.0dci

Digital dashboards, airbag systems, suspension failure, uneven brake and tyre wear are all issues associated with Espace IV in general

Dark was that day when Diesel conceived his grim engine that begot you, vile invention...metallic monstrosity, bale and bane of our Culture, chief woe of our Commonwealth.
