I've recently had a few times where I've started the car and driven with no boost at all. If I stop and restart the car, the problem disappears.

Today it happened again at lunch time but this time the engine management light came on. The code stored is P0236 - Boost Sensor "A" Circuit performance/range

What is the most likely culprit?

Is this with VCDS or some simple OBD fault reader?

From a quick google it could be a problem with the MAP sensor.

MAP sensor in my opinion, not expensive part

Got the code using the Torque app.

Good price on darkside developments - £24 + p&p

cheers

that should do it

The probable causes for this code are:

• intake/exhaust leak
  
• hose connection(s)
  
• MAP sensor
  
• turbo boost pressure sensor
  

Hope this helps

Thanks for that.

As it has been on and off, its not an intake/exhaust leak or hose connection - definitely an electrical problem

map sensor

map sensor

indeed or wiring to map sensor

yup, mine had same code, i unplugged it and plugged it in numerous times to clean contacts and that worked.
