Turbo overboost. Erase and go easier on gas pedal. It happens on my '02 t6 from time to time.

p0234 is engine over boost condition. According to Volvo P0234 is a turbo control valve. Maybe a wiring issue?
Did you do a hard reset after clearing the code? hope this helps!

Boost is controlled by the N75 solenoid with vac' hoses to the vane controller built into the turbo.

When light comes on it indicates too much boost and will reduce fuel delivery to reduce power.
A '' key off/key on'' cycle will reset it if you on the road.

When an over boost occurs it is best to first change the N75 Solenoid Valve and or check the hoses from and to it for displacement or splits.

Before removing the valve, make a note of where the hoses fit.

Common component failure.

check the condition/tightness of the drive belt/belts , also check the cooling fan is cutting in at the correct engine temperature, hope this helps

Hello, your car is probaly a variale vane turbo fitted and all you need to do is seperate the VNT part of the turbo, give it a good clean with brake/carb cleaner get rid of the sticky oily residue which makes the vanes stick on turbo causing a overboost fault, a delearship might tell you that your car has been remapped at some time setting the boost RPM at like 14 or 1500 and it should be like 2200 I do not know the specifics on your vehicle but a good auto manual will tell you at which RPM your boost should build. I would have a diagnostic done and see if this is your problem, if so do the above and go back and see if it fixed your overboost problem. If not, you will need your ECU remapped. I hope this fixes your problem!

P1557 is an overboost condition, poss. from sticky vanes or actuator in the turbo. P1570 is due to your immobilizer being tripped somtime in the recent past. As long as the car still starts and doesn't shut off a few seconds later this poses no problem

This is what my code scanner says:
P0234 Engine Overboost Condition
If you have a non-turbo model, then it's probably something else. It may be a bad turbo overboost switch. My S80 is non-turbo but I had an overboost switch go out on my Mercedes and it shut down the turbo but I had the same error message. Good luck!
