This a load reduction relay. It safely gives the starter priority current (high draw) on start ups. If this relay sticks it will lead to hard starting on TDis.
ECM was not detected during scan in my Skoda Octavia 1.9 TDI ALH 2005. There was a short circuit and I replaced it with a used ECM(IMMO deleted). Now, the ECM is detected by scanner and DTC codes are displayed but the CEL is not ON with ignition ON. Car is starting. CEL was glowing with the old ECM and it was starting in single crank but the scanner count not read DTC.
hello, I have a golf 5 1.9 105 bkc engine, I have a problem, it made a short circuit and there is no light on the board, it starts and the second second it stops, can you help me?
My golf tdi will not start and appears to be doing very similar as your video shows here.. I have just ordered a new relay from eBay as I have no other clue as to what it could be. My mechanic has been out and he's not sure with out diagnostics. Keeping my fingers crossed it is this🤞 will let you know as it was fine when I drive it home night before. Somehow came across your video while trialling other things
golf Wagen indeed! It has been one thing after another recently spending money every week 🙁 I have my friend bringing over a code reader tomorrow in the meantime while I wait for relay to arrive. Will let you know what happens thank you for your reply dude
Sundeep Singh it turned out to be the manifold flap was stuck... Because my bottom hose came loose recently from the intercooler I had both replaced. My mechanic said while I was driving it with this problem most likely sucked up alot of crap that made it stick. There was lots of gunk that we cleaned out with brake cleaner and now it works again. Although diagnostics is showing mass air flow sensor issue and still not running 100%. Cost me a small fortune recently hoping no more issues until I've restored my bank balance then I'll get a new sensor sorted 😕

My 1.9TDI Seat Leon is having issues to start every now and then. Took it to the local garage and the guy there told me that glow plugs are irrelevant for Portugal climate since its never too cold. Also thecar is park in garage. Injectors showing healthy values.. I mean... i trust this mechanic but could he be wrong?
dpf pressure sensor ...it will need changing then put back on vag system at garage to reset all faults then fill car up and take for 40mins drive on motorway changing gears from 6 to 5 5 to 4 then again when in top gears so rpms and exhaust system can warm up then all lights will go out

And this is the correct way to generate a multitude of error codes in different electronic units.
C'est le relais qui alimente la pompe de gavage comme le relais 109 sur les golf 4
Ignition main relay. Used in all VW models, regardless of engine type.

Multimeter is not a reliable way for checking relays. You can check only inner circuit but you can not verify circuit breaker with multimeter.
Hi, what original part number Is this relay?
Yeah i want to know too please do you know?
