ODB II Code P0236 &
P0236 Turbocharger Boost Sensor A Circuit ange/Performance and P0237 Turbocharger Boost Sensor A Circuit Low. I would check to ensure your Sensor is didnt come unplugged and if not I would replace the Boost Sensor. Thanks for Using FixYa!

Radiocode frozen volvo v 40
Remove radio from central console (press two thin vertical buttons on both sides of it). Read and note a radio serial no. on a sticker on radio metal cover. Contact local dealer and give them the number. They will resolve the code for you. Some dealers take some fee for that kind of service. You must ask before.
Wipers make poor contact on V40
Check if the axle is perpendicular to the glass surface. If so, replase the arm because the spring is out.
Are you sure the blade is OK? You can mount a 21" blade to left and right side.
Fan switch
Remove the cover (I use an old CD, not a screwdriver to not scratch any surface). You'll see screws to be removed and the whole module goes out. The light bulbs are mounted from back using flat screwdriver. They are specially designed together with plastic ring and available at the dealer (they're quite expensive). But it is possible to disassemble the ring and replace only glass bulb that is available in electronic store almost free (in Poland about .25 euro).
Many people replace bulbs to LEDs. You can do it or buy needed parts in some car-tuning shop. LEDs are almost endless.
No fuel getting Ito spark plugs
If no fuel is getting to the plugs the inyection system is not working. Check for spark in one spark plug. If you don't have spark that is the reason why the injection is not working. When there is no spark, the ECM or injection computer won't work because it needs a signal from the coil, as s proof of spark..
Code p0234
P0234 DescriptionThe boost pressure sensor responds to pressure changes in the intake manifold. This pressure is created by the turbocharger and changes with accelerator pedal position (APP) and engine speed. The engine control module (ECM) uses this information to assist in diagnosis of the barometric pressure (BARO) sensor and to provide engine overboost protection. The boost pressure sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The engine control module (ECM) supplies 5 volts to the boost pressure sensor on the 5-volt reference 2 circuit, and provides a ground on a low reference circuit. The boost pressure sensor provides a signal to the ECM on a signal circuit relative to the pressure changes. The ECM monitors the boost pressure sensor signal for voltage outside of the normal range. The ECM calculates a predicted value for the boost pressure sensor. The ECM then compares the predicted value to the actual signal.Read more:

2001 V40 boost sensor
Supercharging system using the exhaust gas energy and improve the efficiency of the engine air intake, make more air (fuel) participate in burning, so he can improve engine output power and output torque. General in order to improve the density of air intake and lower the temperature in the thermal cycle starting in turbocharger gas end to connect a cold air for cooling.
