Driving to work dismorning and 25mile into my journey it went into limp code. I plugged in my diagnostics and it flagged up this code. Yet when i turned the car off cleared the code i done 10mile and parked up and no issues.

What is this code?

Possible Causes

• Boost Pressure too High
• Hoses/Pipes incorrect connected, disconnected, blocked or leaking
• Charger Pressure Control defective
  • VNT (variable nozzle turbo): nozzles stuck
• Solenoid Valve for Boost Pressure Control (N75) defective
•  

Mr Muscle time?

 

Have a fiddle with your VNT actuator to see how freely or otherwise it moves.

Mr muscle? Ay

Well lads thats a wierd one. I cleared the eml lihht before i left work then the light never came on once. I had it in my garage for a check over. Theres a slight bit of oil on the bottom intercooler pipe connection but nuffin major but will change for piece of mind. Checked my actuator and it moves freely. So i tuk all vacuum pipes of the n75 and blew them out and then went for a rag about and no problems what so ever:rolleyes:

If it is sticky vanes then it can happen very intermittently, maybe days or a week or two without it reoccurring.
