Volkswagen TDI (underboost) faulty turbo actuator

Seen a few of these on petrol vw also. The arm for the wg flap rusts and causes the actuator to stick in one position causing an over or under boost code. Love your videos matt. Always good to watch with a Chinese take away infront of the TV at a weekend.

It's great that Leon goes with me sometimes. Although I don't think he has any interest in it.

Wish this was my issue, $3,650 dollars later got a new turbo and actuator and sensor all replaced. Very costly and now I am gonna probably have to replace the DSG dual mass flywheel.

I’ve a Passat 2.0tdi and my turbo boost at like 3k rpm but has nothing any lower, I took it to the garage and they said they don’t know what’s wrong with it, car had a new turbo fitted but still the same problem, going to try change the n75 valve out as all the pipes and intercooler are fine so failing that do you know what I should try?

[@bricehale6593]

Would this cause the car to not run my buddy has one it died on us Goin down the road we pulled over popped the hood an there was fuel all over the top of the fuel filter had to have it towed took it to a shop this week and the mechanic said it needs a new turbo 4500$

Hi mate, I have a issue with my audi a3 1.6 tdi coming up with a engine code p023800 as a burbo charger boost sensor A high input. Iv changed 2 sensors, the one at the top near the turbo, and also the map sensor, the car is still in limp mode with the coil spring and ESP light, do you think it could be my actuator? Iv already spent so much money on it and I need help 😭. Thank in advance

[@robert250581]

p2565 can be relative?

[@Fheezi]

Hi Matt my cars coming up with P2563, Turbo Charger Censor is this easy fix and or what else could it be?

[@StreetWraith501]

When you have an under boost from the actuator does it sound or act as when you accelerate the car releases pressure causing the car too have no power unless you let off pedal and then reapply pressure?

[@mechanicmatt871]

I didn't hear any sound of air escaping like a split boost pipe. Just noticed it going into limp home mode.

Hi I have a golf gtd 2019 and have a problem of boost power the car use to pull excellent then suddenly had intermittent boost issues when putting my foot down car will have the pulling power sometimes and now that feel of power to pull is gone the car does drive and pull but not like it did before tried it in normal mode and sport mode even when I use to put in dsg manual mode I could feel the pulling power now that has gone too there are no warning lights on the dash what could it be? Any help would be appreciated

[@lascellebubear4209]

Did you sort this ?

[@user-oj9qw7yx8y]

Have a underboost issue with my seat Leon mk2 170tdi. I have read this is one of the most common issues relating to the code I’ve got. Is it as simple as a straight swap? Or is there any need for it to be set up electronically?

[@user-oj9qw7yx8y]

Like programming it in?

[@3DEWAR]

How did you test the voltage when you moved it?

[@mechanicmatt871]

Back probed at the signal wire on the sensor

[@kellybee1206]

Hi matt where are you based? I have a car for you to look at

[@mechanicmatt871]

I I'm in St Austell, Cornwall.
