I am having trouble with my recently acquired Skoda scout with Bmm engine. I seemed to have sorted some faults but now get the follow codes see images, and am not sure which way to go to diagnose further.

There is another fault no image  egr flow  excessive.

the previous owner fitted

Genuine new egr valve fitted. New pattern part maf sensor. I have fitted new glow plugs which has sorted glow plug fault open circuit on all 4 glow plugs. I also set the torsion value as it was out as the car would pull away without stalling unless Rev’s over 1500rpm, since setting the torsion value car will pull away lovely with low revs. I’m sure it hasn’t got all the faults in the screenshots listed I think some are ghost faults caused by what is actually wrong with it. This is what seems to be happening. If I clear all faults cars starts perfect tickover perfect pulls away perfect if you drive steady you wouldn’t notice anything amiss. If you drive it a bit harder and go up the Rev range to 4000rpm for gear changes you feel it stutter at various points as the revs rise and glow plug light blinks and sometimes elm light comes on. Plug back on Vcds and same faults keep coming up clear drive codes drive again within few miles brisk driving logs codes again ?

I thought possible stocking variable vanes in turbo housing. I have tested turbo actuator and it’s working correctly and holding vacuum.

 

Also would bad eBay cheap maf sensor  be a cause ?

Any ideas welcome please don’t want to just keep fitting parts to eliminate things want to get to bottom of fault and fit the bits it needs 😂

i have Vcds but I’m a bit of a novice on it . Hope I can get some help and sort it.

 

i forgot to say on s long road test motorway doing 60mph steady it has. Lack of power and had a pitched whistle noise at a constant tone it didn’t increase with speed I also knocked it into neutral noise carried on  

when I pulled over noise still there but stopped after about 5 secs when I was ticking over. Not sure if it’s relevant but thought I should mention it.

 

here hoping can get it fixed fingers crossed 🤞 

Here’s a few more images
