Exclamation Renault Laguna II - Phase 1 - Engines - Turbo Diesel Engine Problems

I'v heard so many problems with the turbo breaking down on the laguna's MK2 engine. It's kinda making me worry about my 2.2 DCI , Just one day I guess it will happen to me. I'v heard that it's down to the bearings Seizing up within the turbo diverting all the oil from the sump into the induction system, basically the engine eating it's self. I'v learned that once the turbo fails that the only way to stop the engine is to stall it before the engine runs on pure oil and destroys it. Not the best way to test your reaction against loud bangs and clouds of smoke but could save your engine's life. If this is a common fault which it is and has been for a while. Why haven't these cars been recalled to have a modified turbo fitted, if it is the turbo that is, but this is what is failing, Right. Are modified or stronger turbo 's being fitted to laguna's that have suffered the Big Bang, I guess not. There must be a solution for this???

Hopefully Laguna II Owner may pop over and give some opinion on this Stu.

One thing you have to remember is that a lot of people posting on forums only do so to talk about problems, this can give you a paranoid view of what's going on.

I recently bought a Porsche 996. I was very nearly put off because when you read Porsche forums they would have you believe that every early 996 blows it's engine and ends up costing 12k to replace it.

The truth is that quite a number did have a problem because of a manufacturing problem where by the block was too porous and on 'some' the water and oil mixed causing catastrophic failure.

I still bought one because I've always wanted a 911 and couldn't afford a new one, but I was careful which one I bought. Ultimately I may end up losing the engine but I don't let it put me off enjoying the car.

I'm not saying there isn't a problem with the Laguna's MK2 engine, it's probably been blown out of all proportion though.

What year's your car? Is it under any warranty?

As per a recent post, the original derivative of the 2.2 dCi is know to have problems:

Renault Espace - Engines - 2.2Dti engine - Thrust washer failure

However, the latest models don't appear to have a new EGR valve, which means the dreaded turbo problem *might* recur. If you are buying a new model, there have been several recalls which a main dealer should be able to confirm have been done or not

I am convinced that the long oil change intervals are to blame. I refuse to let my Renault Megane dCi go to 18K before changing the oil . I change it at 10K despite what Renault may say.

Xileno, my Scenic 2 has done about 12000 miles and I, like you, wanted to change oil and filter before the 18,000 service.

I was interested in a deal that National were doing, oil change with semi-synthetic and filter for 15. However, Renault told me that if non-approved Renault filter was used then warranty would be invalidated. Unfortunately National will not let you provide a filter, you must use theirs.

Exact reply from Renault:

Thank you for your recent enquiry regarding the servicing of your Renault Scenic 1.9dci.

I can confirm you are entitled to take your vehicle to a fast fit centre to carry out your service if you wish to do so. However, please be aware that any servicing must be carried out to Renault standards and using genuine Renault parts to prevent any implications on your warranty.

Thank you for taking the time to contact Renault and if you would like any further assistance, please do not hesitate to contact our dedicated Customer Services department on 0800 072 33 72. Our department is open from 8.30am to 6.00pm Monday to Friday (excluding Bank holidays) and is committed to providing the best service in the industry.

So I would suggest you be very careful about your extra oil and filter changes in case you invalidate the warranty.

Its quite ironic that if you do more frequent changes to improve the life of the engine, you could get punished if something goes wrong. However, if you leave it till the 18,000 intervals, and something does go wrong, you will probably be covered!
