Low boost at low RPM
I have a problem with the boost at low RPM, at about 3500 it boost for full and what I understan it should be full at 2500 (or?). I also have a fault code that are 2341. Advice what it could be the fault?

Is your S2 standard? Has it been chipped? Exhaust changed? etc etc
Need more info before anyone can answer questions, altho i dnt think you will get full boost that low down on a stock S2, im pretty sure its higher than that!Ant

Std software -> full boost slighlty before 2500
Typical tuned software -> full boost slightly before 3000
I'd say that your lambda probe is dead.2341 (Blink Fault Code), VAG1551/2 Fault Code Number 00537 Oxygen Sensor Control Limit exceeded, fuel pressure too low or too high, intake or exhaust leak, defective ignition system component, intake air leak after air mass sensor, O2 sensor is faulty Symptom: CO before catalyst is below 0.3% or greater than 1.0%, Extremely lean or overly rich exhaust, Spark Plug fouling

My 1st S2....
I rather rookie about this car.. (have own it about 3month now..) So I don't know if it is chipped or not (how does the std chip look like?) The exmanifold and turbo are RS2 (not 100%...) The rest is std, but I'm not sure... Can you help me straighten out this?Originally posted by S2 AntS2 -91Comment

Well you should have said that in the first place. With rs2 turbo full boost at 3500 sounds about right to me.-Comment

If you want it boost earlier, speak to MRC boys about a stiffer wastegate spring.
Also you may consider rechipping.
Who was the car chipped by?Comment

Chip
Injectors (color??)

No, theres nothing wrong with you car, we're trying to establish what works been done on your car.Originally posted by iMac
The chip is important, previous owner will know, injectors just open the bonnet and see if the tops are green.
The RS2 turbo boosts at 3500rpm by standard, to get it to boost before then means a rechip and a new wastegate spring.

- Minimum control limit exceeded
Low fuel pressure (<3.3 bar)
Ignition system faulty
Intake air leak after G70
Leak in exhaust prior to catalyst
G39 faulty
Fuel pressure too high (> 4 bar)
CO before catalyst less than 0.5%
High fuel consumption
Rich exhaust
Fouled spark plugs
CO before catalyst greater than 3%
Check fuel pressure
Repair air leak
Check G39
Check fuel pressureComment

Could have a boost leak, i'd pressure test your system.Comment
