Turbo-lag in octavia VRS 2006

[gargi]

Hello and happy new year.I own a SKODA OCTAVIA VRS model 2006.Lately i have an issue with my car.I have turbo lag.What i mean:while accelerating with 2nd and 3d gear i can see the turbo pressure in the turbo gauge goes to0.4 bar and then sticks there for a while.The car continue raising rpms and suddenly the pressure goes to normal limits (0.8bars).I can feel that change in cars acceleration.It does not do it every time.The car have 75000 km.Any opinions?Sorry for bad english!

Hi there, I have a octavia vrs tfsi petrol and I seem to be having problems with my turbo only in 4th gear?? Between 4-5 thousand revs it seems just to stop, and there is no pull away at all. All other gears it seems to be fine. Don't suppose anyone had had this issue before? Any help is much appreciated!

So according to this i think that is not something mechanical like faulty turbo because i then should always have problem and not 3 out of 10 times i accelerate.I think might be faulty solenoid on the dv valve because i can hear vacuum/boost noise and i have low presure while the problem occurs.If it was faulty diaphragm i should have those symptom all time.Also could it be faulty/sticky solenoid on N-75 valve?Anyway in two days i will have the car examined by a local garage and i hope to find out what is going on.I will report back the results.Also i would like to listen to your opinion/thoughts.

Get VCDS and run diagnostic - I believe it is similar to diesel engines.

 

It will check all valves and so on.

 

You can also test run with logs - see what happens.

I would like to inform you that i found a solution in my problem.The problem was a faulty dv.Actualy its solenoid.
