I got P00AF00 fault code on my Skoda 2.0 TDI. And boost control A module fault code in Carly diagnostics. The car is not getting more than 2500 rpm.  Can anyone show me with a picture where this module i located? Regards Inge

Welcome to the forum.

 

Diagnosis is a hell of a lot more than reading a fault code and replacing the part that pops up first. You are more than welcome to load the parts cannon but this can start getting expensive.

 

Youll need to start looking at turbo actuators for seizing, if the solenoid is vacuum controlled, needs checking for leaks and if it operates, vacuum pressure itself and many more things.

Of course, it could very well be the N75 valve, but equally there are many more things to look at first.

Context? As this is your first post we need to know what's behind your comment.

Yes, that will be turbo vanes sticking.  You don't say if you have a TSI or TDI engine, but broadly the issue affects both engine types.  All VAG products like being given a load of progressive driving.  I know that is counter-intuitive and you think you are looking after your car by being gentle with it, but VAG cars need some direct - Aktion des rechten Fußes (or right foot action).  Find the turbo actuator at the back of the engine (in most cases) and manually open and close it.  If its seized solid, then it will be a visit to the dealer to fix it.  Hopefully you've caught the problem in time.

 

If you have a TSI, please put in a couple of tanks of Super Unleaded fuel and drive more progressively.  Work that throttle.

If you have a TDI, I (personally) recommend Diesel Cetane improver (controversal, but IMHO it keeps the engine sweet).  A tiny amount in each tank of diesel will keep the EGR clean, the turbo happy, the DPF happier too....oh...and drive more progressively.

 

 

Hi,it's a 1.2 TDI.I do quite a bit of long distance driving (100 miles a time) and generally use a (bit) of right foot!! But it's a used car and I've had it less than a year.my turbo valve (n95) was clicking after a few weeks and I wasn't sure what it was.i eventually changed the part but I still have no oomph.(As much as I was getting from 1.2🤣🤣 ) I'll have a look at actuator to see if it moves.hopefully it can be solved.😊

Do you want to take this conversation over to the MK2 section of the Fabia?  We love to have you here, but you will probably find more assistance / experience with your Fabia in the Fabia section of Briskoda.

I can arrange to have this conversation moved across there as necessary.

 

However, in my experience with the Fabia's, the 1.2TDI's do suffer from this issue.  I suggest that you run some Diesel Cetane improver or a couple of tanks of Super Diesel through the car to improve performance, clean EGR and keep the car running properly.  You will still need to work the turbo vane, make sure they are free.  Soot and build up can cause the car to vanes not to return to the default position.

Failing that, please check to make sure the turbo bearings are good and aren't noisy (indicating failing turbo).

As the original posting was for a MK3 Octavia TDI 2.0, I've asked the admins to put in a link to this posting from the MK2 Fabia section.
