It seems I’m the latest person to add my name to the ever-growing list of DCi turbo failures. My 52 plate 1.9 DCi Laguna (105bhp) with 61k on the clock has blown its oil seals and is forcing oil into the intercooler. My local Renault deal has quoted £1600 (inc VAT + fitting) for a new turbo and intercooler.
I’m considering attempting the repair myself. Has anyone who’s done this before got any advice? How long should I expect it to take? Also any tips regarding the running in period?
Hi L2O. RCS would only go to a maximum of 40%, this was a good will contribution as apparently my car wasn’t covered under the yellow OTS. In the end I had to give in and tell them to go ahead with the work as I desperately need the car back, driving 50 miles a day in and out of London in a Caterham with no heater was getting a bit much.
So last week I picked up the car and the dealer kindly relived me of £1192.68. I also had a new EGR valve fitted which RCS contributed 20% and in credit to the dealer they did do a few extras which they didn’t charge me for.
When I have a little more time on my hands I plan to start writing a few letters to RCS.
WebCode – Thanks for that info, my Laguna falls into that bracket so I’m keeping my fingers crossed!! If I’m unable to get a warranty claim or suitable contribution to the repairs I’ll probably have to do the work myself.
OK I been in contact with the guys from Germany on this subject - who in turn are in contact with the guys from Greece..
"Hi Stu,
just got an answer from two guys: http://www.laguna2.de/forum/thread.php?threadid=13465 is in German, but they say if the car is
- not older than 5 years
- no chiptuning
- not more than 150tkm
- all small and full services are made (servicemanual is stamped by a garage)
German garages need to contact German RenaultNissan branch in Brühl (sub of Cologne) to check the "yellow OTS" in Renault Net or ask a clerk for a release.
Exchange Turbo Fans: my Austrian Colleague has good connections to a Greek Turbo specialist, he will ask him for a Diesel Turbo replacement and prices and I will forward the infos to you. They just replace the fan not the case, this should be inexpensive than replacing all the stuff...
There are Austrian Specialists, too. I will check the infos first...
HTH

So are all UK cars which meet the above criteria subject to a 100% free contribution from Renault UK ?
hi folks,
first off its a 51 plate 1.9dci tourer with 102k
ive just bought it, with my eyes wide open to the turbo probs, i know i know but you cant help but to like them....
the thing is i got it well under my budget and have been told the bearings are sounding noisy so i'm going to have a new turbo put on before it blows.
My main question is...
what needs changing if it hasnt already let loose......
can i just change the turbo and pipes or does the intercooler need replacing aswell
I don't KNOW but from what I understand if the turbo hasn't actually blown you may well get away with just a turbo replacement but I'd certainly if possible give the oil pipes, air pipes and inter cooler a good clean out. Make sure theres no oil left over in any one of these.
Almost forgot the EGR valve will at least need a good cleaning
Also I'd change the engine oil, even this isn't straight forwards you need wait 15 minutes after the the oil change for the oil to bottom out.
Then Gawd knows how, you need prime the oil filter, I guess you need disable the ignition and prime on the starter.
Also make sure you don't overfill with engine oil, this is most important.
But I'd hang around and wait for more educated responses, like I say, most of this stuff in here is what I've over heard, and not from knowledge.
I've got a warranty claim here which is very complicated to read, but it looks like it indicates a figure of £195.00
But this may well include an internal company discount
I just got this from elsewhere, it prolly gives a more accurate reflection on the price of parts including the EGR valve, it won't make you smile, but I hope it helps.
A new Garrett turbo alone is over £1000 and the car will also need a new intercooler, modified turbo oil feed pipes, Mk ll Pierburg EGR valve (£280) and a new catalyst as it will have been contaminated with oil. Ancilliaries plus 100% synthetic oil will come to a further £100 or so and labour will be about £324. I would have thought that the bill should have been closer to £3000 if the job had been done properly.
Sweet Jesus!!! After reading the posts on this thread my a**ehole's gonna pucker up everytime i press start on my Lag!! Now i dont know about the rest of you but it has put me off owning the car a little!Its like reading a Stephen King novel this thread!!I always thought that the Garret turbo was rock solid too,and maybe it is and its just the rest of the car thats poor.I really dont have any probs with mine yet........ (touch wood)........ and i never had any major problems with the old 2.0 Lag.Wheel sensors are a cow mind you but thats something i can live with.When i bought the car i took slight comfort in the fact it had a fully up to date service book.It was an ex company vehicle and is now on 111 000 miles.But after reading up on this it would seem that problems can arise at any stage regardless of miliage,regular servicing etc.Something needs to be done here!Its pretty damn obvious that its now common knowledge turbo's are expiring early.Renault has no b*ll*cks when it comes to admitting failiure on design.I apologise for my "colourful" language but seeing what some of you guys have gone through with Renault makes me a little peeved!They may aswell take the shirts off our backs!!!!!!!
Don't allow you're a**ehole's to pucka :rofl: :rofl: I'd guess the way to solve this problem is by having the engine oil and filter replaced at mileage far more realistic than 18,000 miles.
Admittedly Renault designated the mileage for changes of the above items at 18K miles I'd guess more for the benefit of selling cars to the fleet market, rather than the man in the street who potters around going maybe 10 miles to work and back.
If you consider the Mk1 Ver of the Lag RTDT, I've had both the MK1 & MK2. On the MK1 the oil and filter change was every 6,000 miles, the Mk1 also used a Garret turbo and a Renault diesel turbo engine it seems to me the only thing these car don't have in common is frequency of oil and filter changes.
I'd be interested knowing if anyone heard of a MK1 turbo blowing that has had the oil & filter changed at the correct intervals, I never heard of a MK1 blowing
Also my Mk1 2.2 RTDT at sale had 90K miles on the clock with frequent trips with a caravan on the back, and take it from me in all the time I owned the Lag1 and was towing NO other car with a van on the back ever went past me.
I contacted Honest John about these MK2 turbo problems this is his direct quote
"It's the direct result of the incredibly stupid oil change regime which allows sludge to accumulate in the engine and block the oil feed to the turbo. If oil changes were scheduled at 5,000 miles none of the cars would have any of the problems you describe"
Hondo it all makes sense!!Its obvious that the oil change times are very spaced out even if you stuck the very best oil in your car.For the sake of £30 every 6- 7000 miles it would be far better than shelling out £2000 for new turbo and ancilleries!!BUT i also have to stress to you Hondo,what about the people who are changing their oil regular and still having problems?The oil does play a very important part in the well being of your engine and turbo and you cant just go and shove any old crap in.Ive seen the effects of cheap oil in my dads old 1.3 Escort!Its not a pretty sight when you remove the rocker cover to find a realy thick black sludge circulating around your engine!!!So i think personally that with your oil change you should also consider an engine flush aswell.Anyway my take on things is good quality oil changed at regular intervals with the occasional engine flush.
Just been reading all of th threads on turbo failure as I have a problem with my '02 1.9 diesel Laguna. The turbo failed and I lost all of the oil. Engine reved to 3000+. I stalled it as it would not shut down on the button, but as I was in the road at a dangerous position, I started it up again and got it off the road (20 yards).
The RAC did a great job and got me home and the car to a garage.
We have changed the turbo, cleaned the ECR, renewed the oil feed pipes, cleaned the intercooler. But it will not start. It seems as if there is no compression in that the engine turns over but it will not fire. We think it could be that with no compression the injectors are not able to function, and think that the lack of compression could be due to a valve stuck or a piston ring damaged. However, when we inspected the old turbo the blades were damaged, but did not seem to be broken up and the fact that I was able to start it to get it off the road implies that the rings are OK.
We are now at a loss as to what we can do. one suggestion was to tow it on a bar for some time. Alternatively it looks like an engine change, or a car change.
Does ayone have any other suggestion to help.
Thanks
