i've just read all that and from what i can see, you havent actually removed the one thing i reckon is causing the problem? is that tuning box still on there?

as good/expensive as it may be, these tuning boxes contain general maps and im sorry, but i have a very poor view of them.

first of all, where did you source it from and how much was it?

secondly, take it off and THEN try running your car, if it runs fine without it... theres your problem.

from what i can see, you've replaced your turbo, your MAF and various hoses/turbo lines. practically everything that would be at fault has been replaced, i really wouldnt blame any of the garages, they have done everything by the book.....

Hi,

Thanks, but yeah we have proved it's not the tuning box, It was removed when the fault originally happened and only gets re-fitted once the garages claim they have fixed the problem, once it re-occurs it's then removed as it just emphasises the fault and makes the car annoying to drive...

At VW Dealers - Quote : " It was harder to get it into limp mode without the tuning box fitted, but driving it that bit harder, it was possible"

We also got it re mapped at Just Diesels and the program had to be remove as it cause still caused the problem
Quote : "and the re map was no different to the tuning box"


(PS If you hadn't of guessed I'm RGC's partner)

im not exactly sure then of what point your making

from what i can see, before you fitted the tuning box, there was no problem, once you fitted it, there was.... seems pretty straightforward to what to do to fix it?

i very much doubt a remap is just the same as a tuning box, the method for doing a remap is so much different to a tuning box, plus most remappers have a rolling road, to asess the car and make sure everything is running ok, if not they adapt the various maps to suit your car and its own little 'quirks'.


"It was harder to get it into limp mode without the tuning box fitted" < that to me would suggest then that the tuning box is the source of the issue, im assuming all intercooler and vac hoses have been checked over?

The Tuning box was on for 2yrs and the car was fine!

IT STILL GOES INTO LIMP MODE IF THE TUNING BOX IS REMOVED.

I know the remap works differently it changes parameters with in the ECU, however in is still the same, in the sense of it just emphersises the fault - Meaning it makes it happen earlier in the gear ratio's and at lower speeds!!

dont use caps people think you're shouting at them and you dont want that if they're trying to help you

"

had a tuning box on the car which i disconnected and then took it out on another run, couldn't seem to get the car to go back into limp so figure the tuning box must have been to fault and it was time for a new one. Ordered the new one and by late Feb it was fitted, took the car out for a test drive, yes you guessed it went in to limp

"

that statement alone suggested to me that the tuning box was responsible. the reason the box makes it happen earlier is because it is increasing the boost, causing an overboost far earlier than when it ought to do.

you still havent answered my questions.... have the intercooler/vac hosings and pipes been checked/ renewed?

Sorry about the caps, Initally i had the same thoughts hence why i bought a new one, but it was later prove than it wasn't the case> Really it's not the tuning box, It just needs to be driven faster to get it to happen without it fitted, this has went on for 6 months so I know most of the common problems which have been looked into - An overview

• Checked for Leaks & Blockages in the vacuum system
• Checked for a clogged intake
• Repaced the N75
• Actuator checked by VW, along with other parts & Sensors
• MAF Replaced
• TURBO Replaced
• ECU Replaced

im not sure about this, but i vageuly remember something about ignition timing being slowly retarded by these tuning boxes, im wondering if that could be a possible cause of your issue?

[Mandy]

Is this something that an indepth diagnostics could overlook?

Bearing in mind that the Cam Belt & Timing was done by VW Dealers after the initally problem started.

hmm... im unsure, i only vaguely remember it being mentioned on here in another thread, ill try and find it....

im not sure if it would be picked up or if indeed, its even the cause of your issue. if the timing belt was done by a dealer, i doubt it would be out.

in the meantime, try doing a search for ignition timing retarted, ill have a look when i get chance
