Mk4 Golf] glow plug trigger circuit (TDI PD 150) - Engine, Tuning - It strikes me as a trouble with the intention to require some actual troubleshooting and undertanding of the elec gadget in preference to a few properly that means young lad who has been trained to use the diagnostics in a vw stealers. I assume if i will get my hands on the schematics i need to be capable of make a terrific stab at it (have labored on this stuff alot as an engineer in semiconductor upkeep). Thanks for the recommendation fenwick, will see am i able to locate every person spherical these right here components.
I'm nearly sure the supplier would placed it on the diag, find a few slight troubles with a few elements of the loom and need to update some large sections of it and differnet modules/sensors at a fantastic price to you with no garantee it will even paintings.
My nearby mechanic has a normal piece of kit that he has used to reset codes/errors in the past and it indicates no errors at the system even though this is taking place for several weeks. Would possibly take a journey to vw stealers nowadays and notice will they stick it on diagnositc, however his has worked within the past and have examine reports of issues like this not triggering any errors. Wager they will be capable of point to something that isn't always sending what it wishes for the triggering of the glow plug, or what ever different signal is causing this.
Whilst key in ignition position get clicking relays and flickering glow plug mild, can't begin till get relays to maintain.? engine turns over no hassle, and other sprint lighting are pleasant (although lately changed into getting traction manipulate light on whilst getting no relay motion in any respect).
Was messing around these days and discovered relay 167 to be the noisey one, would love to recognise what the hell it does (best ref on internet is for in gas tank pump on petrol engines).
Additionally have alot of panting (breathing via crankcase) so wager me compression is prob low and won't be able to get sufficient heat on its own to begin with out, however much more likely the elec issue is also failing to provide me power to fuel system so no begin while cranking.
