Hi, I'm having an issue with my van, the EML is on and glow plug light is flashing and i have 2 faults. I removed the boost pressure sensor and it was clogged with soot, I cleaned it but that didn't have any effect so I have one coming on tuesday, but the 2nd fault with the "open circuit message is there as well. Can anyone shed any light on this or point me in the right direction for where to start checking. Cheers
T6 IN LIMP MODE WITH EML AND GLOW PLUG FLASHING (SOLVED)
- Thread starter Will I am
- Start date
A bit of a challenge as there is not much information what's the engine in question.
Please post
Meanwhile - the same fault codes on a T6

Please post
(1) full VCDS Auto-Scan
(2) engine blockmap data - engine stopped (ignition on)
(3) engine blockmap data - engine idling
Ignition ON

Multiple electronic faults, codes warning lights all at once & garage discovered this!
Anybody got the foggiest about what has happened here? 2019 T6 150 DSG 37,000miles 99% motorway Luckily still under warranty Notable Carista fault codes before it went into limp mode & then came out of limp mode & all faults disappeared, then back into limp mode with same faults & some new...
Thanks - that was quick!
I would start investigating with these below as they are definitely wrong.
The pressure reading should be around 1000 mbar (engine off). The 370 mbar in both indicates more or less sensor is offline (sits at the minmum)
Good thing is VCDS reports also raw voltage seen by ECU - almost none (just some noise on return wire). Would expect to see about 1.0...1.1 Volts.
When the sensor is unplugged you should get 5.00 Volts on the ECU side. On the other hand ECU reports open circuit on the reference voltage circuit thus doesn't see the sensor?
Perhaps just a break in the sensor wiring?

Fault code help please
Hi guys I have the fault code as listed below and have changed the sensor but still have the fault code showing after reset. I have no loss of power or any other problems apart from the waring lights. would anybody have an idea of what to try next, Thanks.
Ok great, thank you for that. Its much appreciated. So there's 2 pressure sensors I can see, one after the MAF sensor after the airbox and 1 on the inlet manifold. do you know which one this is referring to? When I removed the one on the inlet manifold it was full of soot, I cleaned it out but I also have another one on order. Cheers
great, cheers
thanks for that, do you know where it was damaged? cheers
Actually mine was diagnosed by the VW techie as a pressure sensor issue but turned out to be the temperature sensor as per the attached link SOLVED - Glow plug & Engine Management lights on error code 15898
