its dead, and vw killed it

[jfoldbar]

kept studying it all day. mayby it spins other way to create vacuum for brakes. that would make more sense. but that would pressurize oil in engine.

It doesnt pump oil to the booster. It is a vacuum pump, as diesels have poor vacuum.

its dead, and vw killed it

i have '04 2.5 tdi t5. ive had the typical starting problems for 6 months. vw insisted that changing the crank speed sensor would fix it even though i told them it wouldnt. since changing the sensor engine has been running rough.(first time its ever run rough since new) slowly getting worse till the point where i couldnt go in 4th gear cause not enough power. changed fuel filter just incase i had bad diesel. it now wont go at all. i also noticed since changing crank that it doesnt blow its normal diesel smoke. i can floor it and absolutly none. i have heard that vw recently has been changing codes secretly to try to cut emissions, then i thought, what better time for them to do it than when changing the sensor, and they will say less smoke cause of new sensor. but when the car was new it blew more smoke than now.

any thoughts on this

Who changed the fuel filter? You or VW?

[jfoldbar]

vw did and put in fresh diesel too

Seek advice from an independent specialist. If you knew changing the sensor, why did you have it done?

im trying to fix the starting probs. vw told me for 100% certain changing sensor would fix it. who am i to question them. and until they changed that i couldnt convince them to consider anything else.
i tried a few independents, but since vw stuffed it they dont want to touch it. 1 guy did and says he has no idea what they done and hes too busy to look at it for 2 weeks. that gives vw 2 weeks to hopefully find what they done

They've done nothing (nothing wrong), they've tried to fix the van that was already broken at close to 200,000km. Furthermore, you were already telling them what was wrong with it. Reading all your past 14 threads you've started, they all are about the problems (and how whoever is working to fix them is not capable) and somehow the van is still going at 200,000km. If you always had these attitudes and you bought the van as new? You have done well and the T5 is remarkable motor vehicle that it lasted that long.

Now, excuse me, I have to merge all your threads you've started, because they're on the same topic.

uuummm, whats your point transporter?. and how do you say my posts are on the same topic.if the topic is problems then sure, but arent almost all topics on problems people have. are you saying i should not post queries when i have issues with my car. how else can i do research?

quote "they've tried to fix the van that was already broken "
they changed a part (crank speed sensor) that was not broken. and now i have more problems than before.
sure i agree that in the process of trying to find a problem then as a process of elimination to find the cause then they must start at the least intrusive and logical and work up. but that is my point, they changed an illogical part. and if it wasnt for my research on sites like these then i would never have leaned about the tandem pump and asked them to test it finding a real fault. while i acknowledge mayby it did not fix the problem either, it at least makes sense that it could be,
i am not annoyed at vw that it wont go at all after changing fuel filter. i realise they had to try that to eliminate a possible cause.all in all i find them quite good. it is quite frustrating though that they dont know what i pay them to know.
this is also the first vw i owned (expected them to be more reliable) and first car i owned that i did not work on, so the first time ive ever been to a mechanic. am i expecting too much?

do you think 200k is a good run? (it was not trouble free motoring though) i dont. mayby some do though

Ive seen a few starting problems in those engines.

Injectors, lift pump, bad fuel. Changing your filter is not going to eliminate a fuel issue. The van i fixed had contaminated fuel - water. The water made its way to the injectors and started to rust them. After a long period of time they stopped working. I sent them out to get serviced and they said they couldnt even get 3 of them to fire.

It wouldnt surpise me if an injector has failed similar to the 2 litre diesels with injector problems.

uuummm, what’s your point transporter?. And how do you say my posts are on the same topic. If the topic is problems then sure, but aren’t almost all topics on problems people have

OK, all the problems you've had, were they the real problems, and if yes, what were the fixes for them? You never said that your van was repaired and it was running well then. So, to me, it is the original fault that needs to be addressed and it will be posted in a one thread. In other words, don't start multiple threads when your van is broken down.

are you saying i should not post queries when i have issues with my car. how else can i do research?

What research?

While i acknowledge maybe it did not fix the problem either, it at least makes a sense that it could be.

No, it doesn’t make a sense! You were wrong with your diagnose and you’re making an excuse for it by saying “it made a sense” (it was a wild guess that you found somewhere on the net and they wasted their time by doing what you wanted them to do!)

i am not annoyed at VW that it won’t go at all after changing fuel filter. i realize they had to try that to eliminate a possible cause. All in all i find them quite good. it is quite frustrating though that they don’t know what i pay them to know.

I’m not sure what you mean by that, but you don’t pay for their knowledge, if that’s what you meant. You need them as they need you and that's it, nothing more. So I call it even.

This is also the first VW i owned (expected them to be more reliable) and first car i owned that i did not work on, so the first time I’ve ever been to a mechanic. Am i expecting too much?

What can I say? One of your first posts was that you were looking for a good mechanic in Sydney to take care of your van at 180,000km. May I ask you? Why so late? How was the van and your mechanic doing up to 180,000km?

Of course you can. Anybody can send the private message without asking.
