Turbo Wastegate Replacment Issue

VIN: WAUZZZ4LX8D023227
Production Month / Vehicle Year: February / 2008
Make: Audi
Model: Q7
Engine: BUG
Transmission: Automatic 5-Speed
Mileage: 111000
Affected System: Engine / Powertrain Engine / Mechanical / External Turbo
Description of Issue: Low Power / Surges / Stalls

Hi Group

Need some help on waste gate module replacement.
We diagnosed a fault as waste gate module faulty. Scan  below.

After module replacement the module needs to be calibrated with VAS6395/1
We do NOT have this tool.

I've been to 2 Audi dealers and they said they won't just replace the module but the whole turbo charger.

I got a part no. from our parts supplier for the repair kit which is just the actuator module.
Since I can not calibrate it, I sent the whole car to the dealer for replacement and calibration.

  • They said they need to change the entire turbocharger ??
  • So I rang the parts department again and this time they said the module is sold with the turbo charger??

There seems to be quite a number of failures of this part and many for sale on the net. 

Just wondering if anyone has come across this and how they calibrated the waste gate actuator module?

Thanks in advance

If i were to take an ESWAG, it should be under  engine (01) > Basic Settings > Adaptation of regulating flap for compressor.

I think Jivi is ESWAGGED pretty good.  I do believe he is correct.

I have an emulation of VCDS, but the battery is DEAD as a Nail on this laptop.

And now that I think of it.........I do remember something similar I ran into, in regards
to this exact issue.  In my case, I replaced the entire turbo assembly with a used one..............
as of course it was for a family member..........not this family.

I could not find JUST the wastegate, even though I had the part number.

Thanks for the reply gents.

I looked in 01 Engine > Basic Settings > Adaptations.
NO Adaptation available.

Not anything to do with waste gate or regulating flap any ways.  erWIN instruction says need to calibrate with tool VAS6395/1.

Spoke with Autologic,  Autologic can not calibrate it.  The tech used it once  when he was at the dealer. no one even
knew that tool existed until then.

I got a part no. for the waste gate module the first time I rang the dealer.
I did not write it down. Next time I rang, they told me I have to buy the turbo??

Turbo cost $3900.00!!
I think the Module was like $500.00 when I spoke with Audi the first time.

Good client, and been with us for many years......so trying to cover all options.

Well Done Son!!

I have my ETKA running on Virtual machine, via the InfoServer.  But I cannot access this until
all of the "Magic" coding is done by my "Crew" and EXCEPTIONAL People.

Thanks for getting this up on the Forum!

Many thanks Matt

Exactly what I was looking for.  I will ring another Audi dealer with this part no to see if available.  We doubled checked
the part No. supplied by Matt Conner with our dealer and the vehicle VIN.

it was CORRECT!

Ordered the part and sent it to the dealer for fitting and programming.  All is well and car is a FIX!
The dealer just wanted to sell a turbo.

Interestingly enough, we had a ~2007 Mercedes-Benz E320 Bluetec in last week.  Similar fault situation.  
However, Mercedes EPC does not show a "repair kit" or separate replacement  for wastegate positioner actuator unit. 

You HAVE TO buy a whole turbo! $$$$.$$   

Though there is ALSO a TSB for that model/engine; explaining defects in the exhaust manifold materials.
Metal comes loose and lodges itself in the turbo's exhaust turbine and wastegate flap.  Yikes!  quoted for new
turbo, new exhaust manifolds, +all peripheral seals, hardware, fluids and supplies.   ~$4600 (USA)

pay-to-play, baby.
