2012 Beetle, 2ltr TDI (CFFB), 56k, FVWSH inc belt

My wife's lovely Beetle has just thrown up 2 dash lights while on the motorway home. Engine light & Glowplug light. Won't go above 60mph so limping I think..

Full scan below.

It's got 4 engine fault codes! Looks like it's the turbo actuator that's stuck/not moving. Reading other posts it could be a few things.

I'm looking for recommendations as to where to start fault finding based on the codes thrown up if possible.

There are other fault codes from earlier this month that I'm not worried about...yet. :)

Does the EGR failure throw up these faults? Are they a 'mare to change?

Two of your codes are self-explanatory, and probably the source of your MILs and limp mode. Your turbo actuator (probably the waste gate actuator...) is stuck, so the sensor that tells the ECU what position it is in is reporting "incorrect" data most of the time. The two most common causes are vacuum leak or corrosion.

Clean and lubricate the actuator for your waste gate, verify functionality by hand, then clear codes and see what comes back. If the actuator is vacuum controlled, then you should also inspect the diaphragm if possible; if not possible, then test it using a hand vacuum pump.

Check wiring and connector to the G581 position sensor. Faults from that sensor can throw both turbo-related codes in your scan.

Finally, have you considered upgrading your interface? You'll get additional information from each error code stored instead of the message "[New feature! Extended UDS fault detail is only supported by current gen. interfaces]".

Thanks for the reply.

I've started the job of diagnosing, all vacuum pipes and wires good but I found oil in the pipe that leads form the engine cylinder head to the cold in of the turbo, not a lot but I thought this should be dry!?

Is this normal/ok?

There's always a little bit of blow-by, anyone who says those lines should be bone-dry is technically correct, but clearly doesn't live in the real world! If it's just a thin film, I wouldn't worry. If it's pouring/running out of the lines, then you've got an issue with your turbo seals, your PCV, or something else.

That's what I thought (hoped), it's just a thin film. Thanks for confirming!
What's the PCV agin?

What's the PCV agin?

"Positive Crankcase Ventilation", a whole series of hoses, check valves, etc. that take the positive pressure in the crankcase (generated by the small amount of blow-by that gets past the piston rings into the crankcase) and redirects it back into the intake manifold. Usually, though, people say "PCV" to specifically refer to the oil separator diaphragm that's in-line.

Resolved!

Faulty/failed N75. Replaced with a new one. All good.

Thanks!
