Hi all, I have an xf 09 3ltr.

As I switch the engine on a second later it says RESTRICTED PERFORMANCE.

I have a scan tool which also a mechanic has done done with his, which was to clear the fault or code, but as cleared it returns instantly and in limp mode.

The code is p00bd I've changed the MAF and air filter with no luck.

Any one been through this or have an idea on how to resolve.

Hi

Ideally you need the codes reading with a dedicated scanner as there will be another couple of digits after P00BD which would help identify the problem. If it is P00BD-67 possible causes are:

1. Boost air solenoid stuck open mono turbo mode
2. Turbine intake solenoid leakage when closed
3. Turbine intake solenoid stuck open mono turbo mode
4. Intake system high pressure bank 2 in mono turbo mode

P00BD-00 possible causes are:

1. Air leak at air intake system A
2. Harness failure - Mass air flow sensor circuit short circuit to power
3. Mass air flow sensor failure

P00BD-07 possible causes are:

1. Boost air solenoid stuck open mono turbo mode
2. Turbine intake solenoidleakage when closed
3. Turbine intake solenoid stuck open
4. Intake air system, blocked low pressure air intake.

Good luck

Hi all. I also encountered the problem P00BD-07 3.0D  Tomorrow I will go again to do diagnostics of sdd. As I see the problem can be solved in several ways. Let's see what the diagnostician says... I'm not from England, I'm from the Russian Federation

Yes

it looks like a duff solenoid on the turbo or an air leak on the air intake
