Sounds like a bloody nightmare for you mate. I would demand that TD pay for labour for taking it off and everything. If not then i would consider legal options tbh because they have provided you with faulty hardware/wrong hardware twice. Why should you fork out for the mistakes?

However if I am honest you can make the diagnoses by yourself as much as we like to all think we know what we are doing get a professional opinion.

 

[majesty78]

Again i would say its not the fault of the turbo. Excessive high mpg can also be caused by a false reading water temperature sensor. You can easy check that with VAGCOM, when the engine is really cold, the water and intake air temperature has to be equal. If its not, or at least almost, then you have your broken part.

Excessive overboosting with a new turbo is mostly a bad mapping, bad adjusted vnt actuator rod, not corrected map sensor or all together...

(Or maybe someone comes to the idea one day, that 230+hp with stock nozzles and with all its negative effects causes turbos to die far to soon, but i guess thats a fact nobody wants to hear in this forum....)

watever the problem is,, id be expecting something done by somebody at this stage

well to be honest i seem to be the only perso tha has had this trouble and vnt actuator rod is a turbo problem is it not??

but mapping wont change once on the car so one minute boosting fine then low boost then over boost then limp mode wont be mapping as the software wont change!!

i will get a professional opinion but vag com brings nothing up so it would be case of take everything apart to look which to be honest i cannot afford this!!

Td said they will cross the bridge of paying when it comes to it but i will push for them to pay as its there fault if its a turbo issue

i know will spoke to his friend who had the same problem some time ago tuned by another company and it was sticky veins so i think i am going to be unlucky AGAIN

 

[majesty78]

Is the basic turbo that you have now new from factory or rebuilt device?

As a further possibility, take a look at the small vacuum hose which runs from your airfilter box to n75.

Does to low boost come also BEFORE you have seen limp mode or only after it went into limp mode?

You must know, that making a correct boost mapping is really a lot of work, most, even very skilled tuners wont be able to make a perfect custom boost mapping within some hours or one day...there are to many factors to be set correct, pre control, PID controller, height correction, map reading, diagnosis data and so on. Also the basic mapping depends on the length of the vnt actuator rod which is a part of the turbo, it moves the vanes to controll boost. (Or SHOULD controll, in your case.)

yeah i see what you mean!i know TD have set up the actuators wrong in the past i hope that they have not done it to mine as i wont be very hapy!

the low boost can come anytime it will boost correctly at 1.9bar then 200rpm later go to 1.4bar then over boost to 2bar then hit limp mode

 

[majesty78]

Sounds like bad boost control to me, but i cant tell exactly without seeing any logs made with vagcom.

By the way, only garrett has a flowbench to really setup the actuator correct.

From the comments made above

This is typical sticking VNT due to wear

Its the use of second hand turbos that have built into hybrid type turbo's .

There are a good few tuners who will not touch the second hand rebuilds , as a lot of them end up sticking vnt .

Its not only Turbo dynamics units , Old TD series form allard use to do the same

 

[strugers1]

ok i have got the raging hump with my car at the moment
ill be taking the turbo off myself to send off to TD then once fixed ill be putting it up for sale as long as i can get finance on the new sirocco
unless i am very very inpressed with the results after the turbo is fixed

then should they not be fully rebuilding the turbo?? or checking these possible faults before sending them out to customers??

 

[majesty78]

Problem is, that most of those rebuild the turbo and clean the inside incl. Vnt with sand blasting which makes rough surface....

It just seems to be that karl is the only one to be having problems with TD's rebuilds

Ive a lot of proof regarding this . Pm me

This is not a slating for Turbo Dynamics , We use them all the time and we find them very good . Its just the rebuilds on second hand hybrid turbos we have issues with , to the point we refuse to tune them because of these exact type issues

 

[jonjay]

TDR - I thought the rebuild process gutted out all the internals and replaced with refurbished internals from other 1st / 2nd hand turbo's. Technically its almost like a new build? Please share the proof any information like this is valuable to everyone.

Ditto, I'd be very interested to hear about any common problems with refurbed TD hybrids seeing as I have recently fitted one!

Its a simple as this , Dont use rebuilt second hand hybrid turbos for high hp TDI's . I am not going to get into a debate about TD .

I am just giving my advice , thats all

Rscott , unless your have issues , dont worry about it . Some of the rebuilds are fine . Its just the percentage rate of new vs secondhand ive the issue with

With all due respect. You have posted 3 times and you could be anybody. I merely asked for you to publish this information, If you dont want to fine however people wont believe you. Quite simple really.

 

[majesty78]

You should believe...but i would add that you should not use high mileage used turbo or one grabbed of junk or ebay which is pretty much the same*g*.

I hope you realise , I have to carefull what I say as I still buy units of TD and I am not here to slate them , Its only my recomendation base on issues i've seen along with fellow tuners

 

[strugers1]

i am taking the turbo off this weekend and sending it back to TD i am not happy in the slightest i understand that some go wrong but i have had 2 now that have and thats not very good at all!!!
ill keep you posted but if any further info comes up please let me know
