Then the one bilingual member of their family turned up, and her mother explained the situation to her. Apparently I'd eaten the bit of cocktail stick that was hidden in the middle of the thing, holding it together.

Ok i heard all about this when it was too late but 2K out of pocker with a fekked engine and a fekked turbo i was recommended no more than 12k between oil changes, that about right?

When you reset the service flashing spanner it comes back as 18k, i know this can't be changed but hopefully when someone buys a Renault with 1.9 DCi engine fitted the seller tells them this..........

Re: Renault Laguna II - Phase 1 - Engines - Turbo Reliability - 1.9 Dci Vs 2.2 Dci

I have a 2004 laguna estate 2.2 dci with a turbo which fails
after 3 to 5 minutes driving? It has 86,000 miles on the clock, and in the past year has needed:
a new catalytic converter; a new key (€150); a new window motor; a new camshaft drive belt.
Now it looks like a new turbo .

Considering that the driving seat is also uncomfortable, compared to an Audi, this is not a great buy.

Re: Renault Laguna II - Phase 1 - Engines - Turbo Reliability - 1.9 Dci Vs 2.2 Dci

More 1.9s fail than 2.2s because more were sold. A proportion of those failures are due to turbo abuse, no cool-down or warm-up. The original oil change schedule was wildly optimistic in this context. Ultimately a turbo is a consumable, so lasting beyond 100k miles is a bonus. The problem is if instead of dying slowly and giving you a chance to get to the garage or even ask a second opinion, it blows up and writes off the entire engine at the roadside.

BMW 320 and 330d had a similar engine writeoff scenario regarding their swirl flaps dislodging and destroying the head and cylinders. But no one on here has been able to point the finger at a specific fault on the 1.9, that could have caused the frequent runaway problem. The fact the 1.9 and 2.2 are so different would suggest the fact both have fallen foul of runaway is a maintenance issue more than a specific failing.

The extended yellow OTS would seem to have gone some way to redress the weakness of the original 18k oil service schedule on these engines, and by all accounts the 2.0 doesn't suffer from the problem at all, no do engines post 2004
