Restricted performance
Hi
Driving to Holland today and 3x restricted performance came up with red triangle. I stopped a few times and message disappeared afterwards. Last time even 45 mins of normal driving.
What could this be please?

Both or one side?
If it's not the manifold or hoses then either one or both MAFs could be at fault.New Defender L663 110 SE (known as Noddy!)

MAF = Mass Air Flow. There are two of them but they are interchangeable if you want to see if either is not working.
Re both, I was referring to they fact that there are two inlet manifolds. Right and left. Only the split one may have been repaired so perhaps the other one has now split if they weren’t replace together.New Defender L663 110 SE (known as Noddy!)

Check the intercooler top hose for a small split - just like on the D3 they split small at first then go in a big way - Part number for the hose is LR076845
My repair was done with a tube of superglue and a roll of electrical tape on the side of the A1
If you take the hose off and seal the inside and the outside then bind electrical tape around it will set strong enough to last for a whileMust stop buying shiny toys....

P006A-00 manifold absolute pressure - mass or volume airflow correlation.
There were no other faults.
Looking online it looks like the Sensors need cleaning, ordered a specialist spray.
Any other suggestion I would really welcome. I drove around today fast and aggressive and no issues came up.
When I had the manifold crack it came up with a constant error

Just like the D3 the MAP sensor gets gunged up with all of the EGR crud - have you taken it off to take a look.
A friend in the office has a 3.0 Rangerover and that had so much crud on the sensor I was amazed it would even operate, it must have worked by osmosis there was no airflow to it at all!Must stop buying shiny toys....

The top intercooler hose is the large hose on the left side of the D4 engine that goes into airbox for the throttle body
