P2006 (Inlet Manifold) and 15560 (EGR) errors 2016 T6 150

I've FINALLY got into this forum - didn't realise hotmail addresses don't work.

I have a 2016 150 T6 DSG with 70k.

2 weeks ago the coil light came on and the van kicked into limp mode. Later that evening the emision control light came on

Initially I used a basic code reader and pulled the following code:

P2006 Intake Manifold Runner Control Stuck Closed Bank 1a

2 days later, no lights on the dash and van driving fine again.

I took the van to my local van centre - they scanned and said there were several errors, so cleared them and asked me to drive until I experienced a problem.

On my way home from the garage, when pulling away from stationary, the van went really rough for a few seconds (not done this before) - it cleared itself, and drove home fine. However, the coil light reappeared that evening.

I decided to upgrade my crappy OBD reader and bought a Carista. Plugged it in and pulled the code 15560 EGR Sensor "A" Circuit Range/Performance.

I reset this to test when it appears - every time stop/start kicks in, if stopped for more than around 45 seconds, I get the error 15560 EGR Sensor "A" Circuit Range/Performance. I've cleared the code and tested it around half a dozen times - the code reappears so I think is consistent.

The van has run fine during the day and no lights on the dash. If didn't have Carista, I wouldn't know there was something going on.

I've done a lot of reading today and found one post which has my current symptoms - 15560 error after a long stop / start but van seems to run OK. Unfortunately the post doesn't say what the fix was but he was suggesting he may replace the EGR:


I believe the EGR valve sends exhaust gas into the intake manifold. The original error I had from a basic code reader was P2006 Intake Manifold Runner Control Stuck Closed Bank 1a.

Now I'm seeing 15560 EGR Sensor "A" Circuit Range/Performance (and one occurrence of the van running rough at low revs), I'm wondering if it could be the EGR valve that's suspect, and over a period of time, it results in the intake manifold error.

Is this plausible or am I way off?
 
The van has run fine during the day and no lights on the dash. If didn't have Carista, I wouldn't know there was something going on.
As mentioned in the linked thread, the 15560/P046C fault code alone (=no other EGR related faults, no dash light) is not a concern.

But if that still bothers the way ahead would be to verify the actual EGR valve operation, e.g. as here

P2006 Intake Manifold Runner Control Stuck Closed Bank 1a
More likely a separate issue, not directly related or consequence of 15560 fault.
 
Thanks Mmi, I've not had the van long - waiting for the engine light to come on again before I can pull any codes is agonising, I might get the valve tested when it does go in, to rule it out completely. P046C00 / 15560 appears every time after a lengthy stop / start - any idea why that would happen if there isn't a problem?
 
Based on quite a few postings around the Forum it seems that P046C00/15560 won't turn on any warning light on dash. Of course it's an indication that things are not the same as new. A kind of interesting thing is that - as you have noticed - the fault is registered only when engine is stopped - probably becasue the EGR valve does then a couple of full sweeps - depicted e.g. here - possibly explains your observation about 45 seconds:




However, the P2006 can be a nuisance because of turning van into limp mode.

Also would be good to check that ECU is up to date re software updates. Please post "Detailed ECU info"-report (under Carista Service menu).
