Hi all,
I am currently chasing down an issue with my 2015 2.0tdi 184 Leon FR (CUNA) having the Engine light pop up.
I can't visibly see any damage to the top of the engine bay harness and have already changed the pressure sensing glowplug out.

I am getting P13D4 short to plus and P13D6 signal implausible signal.

These log after ~20 mins of driving and a few days later pop the EML light on

Has anyone else had a similar issue and know any common places to check for damage or suggestions? (The garage has already had it in once and booked again next week)

Live logging of the pressure sensor shows realistic figures inside of the cylinder with no gaps in data at standstill.

Would a whole new circuit (https://seatdirectparts.co.uk/parts...-leon-2013-2017-tdi-glow-plug-connector-4pin/) be the next best step?

Thanks in advance,
EJF
