Glow plug light flashing fault code 16056

Hi .have had this fault for a few months now. When engine run from cold , glow plug light starts flashing and goes into limp mode. Won't rev past 2800 rpm. Van still drives OK. As soon as engine temp reaches approx 70 degrees I can clear fault and it doesn't return.
If fault is cleared before engine is warm then light comes back on.

Have had oil pressure checked and another new oil filter but fault still there.
Any pointers would be appreciated.

Sorry.
Forgot to mention it's a vw t6 2017 150bhp highline 6 speed manual.
Cheers
 
Has the connector and wiring been checked on the oil pressure sensor plug? Oil pressure might be a red herring see;
 
Unsure if this has been checked.
Is the sensor and wiring accessible?
If so could check myself.
Have seen other posts of similar problems.
Just seems odd that fault only happening when engine cold....
 
Hi Stead4119,
Just wondering if you got to the bottom of your issue?
I’ve got the exact same issue on the same van (only happens when cold).

Hi Phil.
Yes. It was a faulty oil pressure switch.
There are 2 apparently and it was the one at front of engine.
No problems since changed.
 
That’s great, thanks for the update!
I’ve got mine booked in so I’ll let them know, hopefully it’ll be a straightforward fix fingers crossed.
