Hi Guys, Salvaging an old thread here, this morning my car went into limp mode and got this fault. This afternoon car drove fine, no issues however i can see a dirt splatter where it looks like a seal has failed on the end of my swirl flap actuator. I'll do some output tests to see the VGT working. I'll also see if i can test/read N75 & N18 valve. Does anyone have a picture of N75 & N18 so i dont have to go hunting? Next is to replace the manifolds as i now replace every plastic part having being plagued by VW plastic rot on my other car. (Mk5 Golf)
Laggy
If that fault 16619 is what you got and you have a V6 Tdi it will be the vanes sticking in the turbo.
I have one on my bench at the moment that the vanes were near seized solid from combustion crap. ( i have successfully cleaned and freed up all the vanes and reassembled this)
I also jut pulled one apart a member from Sydney (Hi Allen) with only 130k on the clock with the same issue to a lesser extent.
One of these had 300k on it and the other 130k and both turbo center bearings were about the same condition.
Most people just replace the turbo ( a brand new Garrett one can be had for about $1700 vs a brand new VW (again Garrett) for $3800 and none in Australia wow that box must be expensive to make)kaboom
That is for a CASA eng your is most likely the BKS eng which will be slightly different and quite a bit harder to remove than a CASA one.
The Turbo can be pulled apart and the vanes cleaned and put back together for no cost bar the assembly gaskets which you need for a new turbo if you do the labor yourself.
I am a tight arse and will not replace anything if i believe i can repair. I am also married with kids so have no money :laugh:
By the way you will only have an N18 valve to control your EGR valve no N75 will be present.
The manifolds can be really easily repaired to new condition.
I even have an exchange set if you were interested
