Tourneo Custom 2015 2.2 EGR faults - Bristol Help Needed

[Ash2026]

Hey all,

I'm looking for a member with FORSCAN who has experience with the live data and codes.

I have owned my 2015 2.2 155BHP for around 7 years now. Never had any 'big' issues but seem to constantly be chasing the same one recently. About a year ago the van started to run rough, the idle seemd very low and between 1500 - 2000 RPM the van would hunt. Initially this was just uphill. A while before this the van had a seized EGR and so I replaced it with a 'hella' part. From what I read, these are decent parts and so should have been fine. I would say now that the hunting only started after changing the EGR. After a few months I took the EGR back and swapped for a new one, assuming a fault.
Problem is, I still have the hunting.

Things I've tried so far..
I've changed the EGR (twice)
Changed the MAF - for bosch part
Changed the air temp sensor - lower intercooler pipe
Van has had a clutch and DMF - although after the fault started

Randomly - If I disconnect the EGR the van runs lovely!
I have used a cheap basic code reader on the van, watching the live data the 2 EGR values change whilst the van is idling. I'm 99% this is the issue with the hunting, essentially the EGR is opening and closing all the time randomly rather than under acceleration.

Any help would be appreciated!

You need forscan to monitor the EGR properly (put it another way -- you need forscan to be on the level , in the same playing field, with what most here understand)

and what to watch are:

EGR "commanded" in percent
and EGR "actual" in percent .
they should follow each other

Whilst there you should also be following what the turbo actuator is doing .. again "commanded" and "actual" in percent - they should follow each other.

also have a look at the boost pipes .. look for a hole near the alternator common on some models.

both EGR and turbo actuator may upset each other.. and make one play up when not at fault as they both react to the maf sensor reading which will be out, if either of those are

forscan is free to download to a laptop .. you just need the v-linker cable £25

and forscan may bring up more codes which may help .

all the best.mark
