Guys, just to report back. The problem has been solved. The car has been sold 😁

Guys, back on the Fabia today…. Changed the Maf sensor and no improvement… Since there is a misfire as soon as the rpm passes 1000, and the rom needle will oscillate ever so slightly, the first thing I would like to try is to swap the injectors for the set of ARL injectors that I have. My engine is BLT, not ASZ, so my question: If I do have injector issues, would a set of healthy ARL injectors restore power even though the car would idle roughly?

W Thanks for the replies. I just saw that actual turbo boost value was almost 2.5bar, third gear full throttle…The car is like trying its best and then when the turbo should really pull I can hear a sound of air huhhuhuuuh and a faint squeal from the turbo…. It’s boosting well, the turbo is in great condition, but all that psi is going nowhere….I don’t think the mechanic did any logs… Sry guys, I am not a mechanic and I don’t have access to equipment… All I can do is listen to you and see what you think, give a mechanic a hint…

Ok. Got it… What about testing the injectors with the spare AL ARL injectors? Swap and see what happens…I have a slight misfire, tractor sound… The mechanic has used an injector kit like this so I suspect he has done something wrong…

I have just had the Egr deleted from the Ecu and it didn’t solve the problem… 😞

And how about a puff of white smoke when I start the car. Is it normal? It clears away instantly, but it is undoubtedly there… Could the injectors be working well at idle and show nothing out of the ordinary on vcds, and be bad under load… Now that I have ruled out the cam… I suspect injectors… The fuel consumption has gone up, the white smoke on start up… What do you think? If you think it is a possibility, could I test it out with a set of working AL injectors from an ARL engine. I know the idle will be rough, because this is not ASZ but a BLT, but will they give the engine enough power under load?

Small update. I have put back the old camshaft and that did not solve the issue. The car is still low on power and high on fuel consumption… Something else is holding it back… When I disconnect the vacuum box clip and try pluging the holes with my finger, only one hole will suck in air…Is that how it’s supposed to be? Maybe it has a faulty vacuum box… Could the under fueling issue still cause higher fuel consumption, although it doesn’t make sense?

Has your BLT run fine with the Egr deleted and EML on? or did it experience a loss of power? I have removed the EGR, but I also changed the cam and injector seals, and now the car is down on power…

Hahah true… I think I am more likely to map out the Egr and put the old cam in…see what happens. And if it is the same, then the car has some other problem, which I believe it does…maybe fuel related… When I floor it in third gear I hear the turbo working and trying its best but something is holding it back… The car had had that Egr releted code and wasn’t amazing on top end power even before the cam change, so changing the cam and deleting the Egr might have just just exposed some underlying problem… I have been driving TDI PDs since 2004, and I know that this is not the normal sound, regardless of whether it is cam related or not… This choppy sound wasn’t present with the old cam.. And a healthy tdi pd isn’t supposed to sound like this… It’s either some sort of fuel restriction, or this cam inside is garbage… https://youtube.com/shorts/XdwkwwyL3NQ?feature=share If the car didn’t look like it was 3 years old, I mean it is really in mint condition, I would have set it on fire. The funniest thing is no codes 😂

And just did a bit of research. All the TDI PD 8v camshafts appear to be the same. The only difference is the alloy, slightly different and stronger for engines with DPF. So my issue isn’t cam related, although it manifested itself after the cam change… The first thing I’m gonna try next week is map out the DPF, and I am positive it’s not gonna do any good… Jesus, it’s like I am fixing a Tesla. Crazy…

https://www.kmotorshop.com/en/content/detail/139/identifying-the-right-camshaft-for-bls-engine HVO287 (in my car) is for engines equipped with DPF, HVO 285 is what I should have taken... Whether it matters or not, I do not know!

Found this. I have 038 109 101 AH and an 038 109 101 R is what I should have taken. I'm gonna put back my old camshaft and map out the EGR and see what happens.... https://www.myturbodiesel.com/threads/pd-camshafts-2008-golf-tdi.29935/

Can you tell me how to check fueling in VCDS while driving?

The car doesn’t smoke at all… Is it possible that there can be some kind of fuel restriction that doesn’t result in jerking, shaking, stuttering, cutting off?! I am going to map out the Egr but I don’t have high hopes…

The idle is fine once the car settles down, but after a longer drive, there is some weird faint knocking and tapping that shouldn’t bethere…
