    i did wonder on best way to widen debate to turbos of other makes .
    I heard something similar prediction on BMW ,as i understood ,service interval are around 20,000 km, and turbo life was being debated the point being made was the basically, engines are still the same but additions like turbos ,DPFs,etc so chemical additives are used to extend oil life, not always to engines benefit,Ford also feature in turbo related debates as i believe does Peugeot, most car makers are buying turbos on Tender process.
    Battery life is another issue .a visitor to a battery manufacturer plant told me in his opinion if plates were kept up a quarter inch from battery base they would last 20 years but are measured and set in such a way that as they wear bits fall off and when they make contact at base that cell is rendered useless.
    so are we looking at market policy of Designed to Fail and we as consumers are [paying the price

    Don't reduce it to a conspiracy theory argument. People are buying diesels and not doing the mileage to get the oil hot enough to boil off the water vapour and general condensation within the engine while sticking to already optimistic manufacturers servicing intervals. Penny wise and pound foolish. Unfortunately I've been that soldier. Car batteries are lasting longer than they ever did, they fail suddenly not like the old days which can be very inconvenient.

    A large part of the problem is an attitude that cars haven't changed in the last 30 years and owners and mechanics treat them the same way they did then. Car technology has moved on hugely in the last 30 years and modern cars DO NOT TOLERATE SLOPPY MAINTENANCE AT ALL. If you deviate from the manufacturer's instructions, you're inviting trouble.

    Couple that with people buying cars that are not suitable for their use cases (diesels for town use mainly) and it's a growing problem.

    point taken,:)
    the battery issue opinion is not mine, his point is they could last years longer if manufacturers wished
    re turbo issue they will be fitted to more petrol engines too so service intervals and oil choice will become more important, any way some recon its your luck or lack of, the car you buy will either give turbo issues or never will so is that a manufacturing issue,parts supplier or whatever,

    Even manufacturers service intervals are pushing oils to their limits especially in short trip cars. The long and the short of it is that modern diesels need to be doing the mileage to avoid expensive problems further down the line.

    that's a real eye opener of service related problems must try downloading and show it dealer ,

    Would you be better off blanking off the egr?

    On old diesels it was a good option but not always. The ECU controls the egr and just blanking it out cause warning lights to pop on.
    This can be overcome by programming out egr errors.

    Most egr fail because they are clogged up with coke usually made worse by turbo leaking oil into engine intake.

    Personally I try keep the egr unless you know for certain that its a good mod for your engine.

    Landrover discovery owners often do it and it improves the engine but they are old unrefined lumps.

    The Egr doesn't make carbon / coke build up so if it need regular cleaning or replacement there is a underlining problem with engine usually its burning oil

    but with repeated turbo fault I would be looking at oil pipes oil pump and gasket seals

    I drove a renault diesel with coked up egr for 6 months before realising. I was tracking down why it sometimes stalled when moving off from stop that it cut out. I had presumed renault dealer cleaned or checked it when they fleece me for 2,300 euro for turbo and intercooler repair.

    All I can say about main dealers is they are expensive

    A device like that is overkill in a normal turbodiesel car. If you're losing turbos you need to look at how the car is being maintained. If the car made it to 120000 km on the original, then it's not a faulty part or a problem with heatsoak at shutdown: both those problems would show up far sooner.

    I'd guess most of the blame for the second failure can be laid at the door of the mechanic who changed the first one not changing the oil and filter at the time.
    120,000 km is only equivalent to 72,000 miles car serviced at 15,000km/9,000miles by main dealer. only thing i noted looking over service record is car was serviced when i purchased it 20,000km/12,000 miles after previous service,so car was probably traded and not serviced until i purchased it.in view of item posted by GCTEST50 could oil carbonise and create problem similar, even though i would venture guessing carbon in injector ports would signify some contribution by dsl problem or impurities eg washed diesel,
    BTW i offered to pay for extra service,told no need as serviced 2,000 km previously and told that servicing with change of turbo is not requirement of 12 month warranty on turbo

    I think you really should consider going to another garage.

    well as i said earlier i did have a "discussion" re turbo fitting without changing oil and filters,with that main dealer,went to another toyota main dealer to service a few weeks after,haven't been back since .
    if link posted by GCTEST 50 is anything to go by however the damage was already done. engine model or make is irrelevant i think, however i also contacted a few other main dealers re fitting new turbo and their response is same, its not requirement of warranty by Toyota to service car when replacing turbo.Toyota Ireland contacted me last week re safety hitch check to be carried out on all(i think) 08 Toyota avensis cars so must get onto a main dealer now for that purpose,
    contacted a breaker since and his advice was fit an engine out of crashed car that has original turbo ,for about €1500 its not a bad option,me thinks. was considering fitting newer model engine but he thinks it does not fit ,any views on that. 08 is really too old to trade up by 4 years cost wise (around €15,500)so considering running into ground if it stays going.Corolla approx €13,500
