Big Turbo Problems

nom · Post by **nom** » 06 Jan 2011, 02:23

I have a 2005 S40 1.6 SD. 85000 miles. At 82000 The turbo went, so I replaced it. Carried out all instructions, taking off sump, cleaning strainer/pickup. Cleaned out oil cooler, and oil filter housing. Cleaned all hoses, pipes and especially banjo bolt that screws in to block and is for turbo oil feed. Did required oil flow test. Changed oil and filter after 100 miles. Turbo went after 3000 miles. I also noticed when I took off first turbo that it had been changed before(as any awkward bolts had been left out).

I sent the turbo back to supplier and am awaiting resolution, but am not holding out on any decision in my favour. I enquired yesterday to price a new strainer/pickup for the oil pump, the parts man in the Volvo parts department, acted as if he never heard of such a part and had never had a request for such a part. I find this hard to believe as the turbo supplier said he was amazed that this turbo was such a popular part. I would be suprised if the strainer/pickup was'nt popular as I feel it should be changed.

I am going to repair it and trade it in as soon as I can. I bought it 12 months ago with the hope of 2 to 3 years of trouble free motoring and it has cost me a lot of money in that 12 months, wheel bearing(rear) alternator, intercooler pipe, turbo x 1 or maybe 2. I am totally gone off VOLVOs, or am I unlucky. All the mechanics I have talked to have said this actual engine and turbo are a diaster, is this true.

Just looked up the Volvo U.S.A site for the Diesel powered S40.

It seems that it's not sold in the U.S.A or Australia where I am from (two markets where the buying public is still coming to terms with the acceptance of diesels)

I wonder if the turbos for the diesel are made in the same factory as the petrol models.
What brand of turbo are you replacing??

The pickup pipe, if clean should last the life of the car. Is the flat surface of it machined correctly?

What part of the turbo exactly is failing? Does the turbo specialist say the failure (first and second) are caused by oil starvation? Does your car have a turbo timer? If not it may be time to fit one.

Thanks Mike

I am in Northern Ireland. Alot of people here prefer the diesel for economic reasons, and the modern diesels are getting smoother and faster.

The engine in this S40 is a Peugeat engine. I t must have been the bearing ran in the turbo. The banjo bolt in the block has a very fine wire mesh and the slightest bit of debry will starve the oil. The strainer is a wire mesh one but you only have access to about 25% of the mesh as the rest is covered with plastic and it is near impossible to clean properly. For this reason I am going to replace it this time.

After speaking to people and reading some reports the turbo runa at extreme speeds of 230,000 revs/min, it is a 1.6 diesel but they have made it into a very powerful unit with this turbo, I just wanted to have a good realiable small diesel. Not this one. They even advise that the turbo will show signs of damage at about 30,000 miles if oil levels and changing intervals are not adhered to, I can only say the were from the time I have this car. This same engine is used in many different vehicles: Citroen, Ford, Mazda, Mini and Peugeot and Volvo. Ashame it isn't great as the car is a beautiful one.

Thanks for reply
