I am having probs with my van , it started a couple of weeks ago after heading to work the van went into limp home mode.
I removed the charge pipe to inspect for leaks all looked ok and refitted the van has been fine until today I left home and it kept going into limp home mode.
The eml is on so have ordered reader for this , this came up a while back after going through a puddle

It's probably not a boost leak if eml is one,

hard to say what it could be but two most common causes are injector no1 wire and a bad maf sensor - if your mafs already had the 'puddle treatment' then it may have finally died :(

Engine management code readout should help confirm!

Looking at other posts it's either the egr or tps , it's always been lumpy at low revs when cold which is an egr issue.
I ve ordered the pscan reader , so will look at the codes plus disable the egr to see if it makes a difference
The maf is on roverrons box , I disconnected the whole thing to see if it effected it, as I know from experience disconnecting the maf will prove any issues

well, disconnecting the maf will help identify maf related issues (which can be quite complex as it covers the egr to some extent) though it wont go beyond this

a tps fault would normally force the engine speed to a fixed engine speed so it's unlikely that, egr I don't think has a fault classification high enough for limp mode directly but if accompanied with maf failure could be.

See what the codes say :)

I was using the van this week gone, power right down and if you accelerated lots of un burnt fuel out the exhaust, so had anoTher look at charge pipes and found a split in intake pipe.
I went to breakers yesterday looking for a pipe , I found a r45 which had a pipe fitted as a temporary repair so I have used this and will order a new one .
I used the pscan today and read I reset codes, mainly to do with maf and airflow codes, but as I dis connected the maf I may have brought these up.
The tps had a logged code so will see how it goes
Pscan is a code bit of kit I also reset the service light on my ZT
