16056 error code (again!)

Hi. As this is my first post I wasn't sure if I should start a new thread or reply to billybonko's thread of 5th Sept, as it is so similar to my issue? I tried the latter but don't think it was visible to anyone? So apologies for repeating as a new post!

Firstly, I should say 'thank you' for all the useful info I have picked up here, a great resource.
I haven't really delved into diy vehicle maint since the days of vauxhall chevettes and cavaliers, so this T6 (CXGB engine) 2016 is quite daunting. I've not had many issues in the 6 years 35k miles but now, coincidentally(?) since a timing belt and oil change, I have a flashing glow plug when cold with Carista showing the errors 15560 and 16056. My local VW specialist say it is an EGR problem but looking on here, and as for billybonko's issue, some have fixed this by changing the Oil pressure sensor for low pressure. As all is good when warmed up, I thought I'd take a punt on the oil sensor. After several attempts and reference to the manual and extracts posted here, I have found it! I think I can get an open ended spanner on it from the angle in my photo but the tricky bit may be releasing the connector! I presume there is a tab on the right angle connector to release the locking hook? The manual drawings don't show that detail so I'm hoping someone can help with a picture or what to feel for?! I can only get 1 hand in, either from the right side or from the left over the top.
Failing that I'll have to bite the bullet and go to a main dealer. Thanks in anticipation.
Pete

Re the fault 16056 have you already checked this thread:

Thanks mmi, I hadn't seen the first one re 16056 error. Lots of interesting stuff there. I don't know if Carista can do live data logging, I'll have a look.
Still tempted to change the sensors and perhaps the valve as they're not expensive.

16056 fixed by changing the brown oil pressure sensor - 5 min job. Shame I spent hours changing the green sensor and regulating valve first! Must be a moral to the story!!
