D4 Red triangle restricted performance

Not replacing the injector pipes as stated by LR as single use only? The pipe seats are soft for the other side to bite into to seal but if refitted at a slightly different angle then they risk not sealing.

Thanks Graeme will want Mr Automotive about that.

Well got the Black Panter back and couldn't be happier feels alot better and looking forward to going 4WD in it 😁,can't say enough about MR automotive they have been brilliant.
Cheers Dec.

Good result plus you now know that these problem prone areas have all been attended to, should give you confidence for the foreseeable future.

Does anyone feel like guessing what's going on if the MAP is triggering reduced performance under load around 100kph - 2000rpm in 5th or 6th, but not if I drop to 4th and get the revs up past 2500rpm?

Also, are the sensors just plug and play? Anything to know about replacing them? Thanks

I don't know for sure, but it could be as simple as the torque limiter for the selected gear.

So 4th May be limited to 80% of the engine output, which in turn means the engine is far less likely to trigger map related faults.

All sensors should be plug and play as long as they are replaced with the same part number.

Mine behaved like this initially, my theory was that the boost was growing faster than the leak. In my case manifold.

You most likely have a leak somewhere. Get or do a smoke test.
What is the specific error code?

I should have prefaced my comment with:

"You probably have a boost leak somewhere"

But thought it went without saying... My bad!

It's the "P006A-00 Manifold absolute pressure - mass or volume air flow correlation" one. Manifolds have been replaced a while back (guess that doesn't mean one couldn't go again), and also the intercooler hose, though that was more straight forward - foot down, performance restricted (and gaffer tape patchable!). This one's weirder. Guess it's leak hunting time either way... thanks...
