Default Turbo Problem

My car started making this siren like sound with a sudden lose of power and threw the "glow plug" light into a flashing frenzy. I suspect the turbo. My DPF has been "unclogged." I just have a few questions. ALSO, I seem to be losing coolant quite frequently, about once a month I top it off with VW G-13 or Distilled water.

1. Does the oil cooler have anything to do with the turbo?

2. Any advice on replacing/rebuilding the turbo?

3. What COULD be the problem?

Thanks for the advice.

1. Yes. But, why do you ask?

2. More info required to determine relevance, see below.

Have you pulled codes with VCDS or equivalent?

No I have not pulled the codes yet. I am pretty sure my oil cooler/lines are leaking oil. I ordered the xtool Vag401 to read the code. But it hasnt come in yet.

Had the same symptoms as you on my 2011. Mine eventually went into limp mode and had the car towed to the dealer. Turned out to be the actuator. The dealer replaced the entire turbo along with the actuator. Everything covered under the post-fix extended warranty. Thank god. Hopefully your dealer will do the same for you.

No to DIY rebuild of turbos. Replace it.

I recommend YOU DON'T DRIVE THIS CAR ANYMORE.... The turbo can fail and send crap down the pipe into the DPF and CAT and EGR Recalculation Valve and destroy them. It can also pipe engine oil out the tail pipe so fast, all engine oil can be drained within minutes. A failed turbo can do awful things on the same order of a failed HPFP....

Actually sounds like the turbo has failed and depending on how it failed there is likely metal in the intercooler. When mine went I had the replace the intercooler as well because they could not get all the metal out after repeated flushing. Wasn't worth the $300 savings to risk losing another turbo at $4200 installed. Mine had all your symptoms exactly. It never went to limp mode. I could drive it but it sounded like it had a clown car siren on it and had power loss.

Do not drive it. See all those missing blades. Plus that piece was still loose inside the turbo housing flopping around as well as the fan on the other end of the shaft that broke which would just add more metal fragments everytime it was driven. Any of that metal makes its way into the intake and it's pretty much game over.

Car was towed and has been parked. Trying to decide if I should take it to MF Auto, whom I trust and have worked with before, or just attempt to replace a new one myself.

I have not removed the old turbo yet. Trying to decide if I can replace a new one myself or if I should just get a local shop to do it.

I ran the code tonight and got "000665 Boost Pressure Regulation Control Range Not Reached." Any advice?

You didn't accept the VW emission fix? Had you took the emission fix offer, this turbo problem would have been simple warranty issue fully covered by VW.

In a previous reply I explained that I bought the car used and was not eligible for the emission fix as the previous owner had already registered the car to be fixed. Something like that, I tried to register for it and was not eligible.
