code reading PO 100 on my 406 HDI?

Post by pugface406lx »

Anyone any ideas whats going on with my HDI...code reader says PO100 which i believe is Maff Sensor on air intake...I replaced that but still it goes into 'Limp Home' mode at 2800rpm.
Also noticed it came up with 'Turbo boost pressure' on the reader..???...any ideas on that one?

Are there any other sensors on this vehicle which could be faulting??

Cheers

I'm going from many posts on here, have you got a boost leak?
406 estate, 2.1TD, I fixed her, then part exchanged her for a Mercedes E300TD Avantgarde Estate.
Hmmmm, straight 6 goodness!

is that the right code ?, it sounds like you used a generic code reader and its displayed a random code !, and if it is a generic scanner, they quite often done even display the proper codes that show where the fault is, i have scanned with a generic one before and found no faults when the engine light is on, but put it on planet straight afterwards and 4 or 5 error codes show up !

you could be chasing round and round if you are using a generic one, best to find someone near you that has planet to do a scan for you i think
