Great content bro had a similar issue in the Kombi t6 the problem was the EgR. And also where can I find that wiring diagram. It makes things so easy especially diagnosing this kind of fault
To verify if its ECU or a real short you can use your test light from battery + to the shorted 5v ref, if it lights up you have a sensor short revealing a real short to ground, if it doesn`t the ECU is at fault.
Good video Alan, I checked VW wiring diagram and no reference to B circuit, it must be an internal circuit within ecm! So best course of action is just disconnect any sensor you find! Cheers sandy
I think I would have to cut the 5V wire from cpu to the boost pressure sensor and if I got 5V at the cpu I know the cpu is good same as disconnecting each sensor could go that way if the sensors were hard to get at
Good case study Alan. Nicely executed fix too. You didn’t miss me too much so 💪💪
Plenty more case studies up there for you next week 😃
Muhteşem bir video sayenizde arızayı iki dakika da buldum teşekkürler bu videoyu paylaştığınız için
Brilliant I’m glad it helped 👍
Well done Alan. At least the new Booast Pressure Sensor is clean😊
😂not for long I’d say
very good, thank you!!!

Thanks for watching dude I printed out the wiring diagram from Autodata I find it good but it doesn’t have diagrams for every car

Thank you David 👍

Yes cheers Sandy I was pointing the finger at the ECU for a little bit thank goodness I didn’t go down that rabbit hole
Always the last sensor checked...strangely this time wasn't the hardest to reach 😂
Wonder where the under tray went, stuck in a field somewhere .
😂 probably
Good video
yeah, internally shared 5v quite common. cut 5v wire at ecu confirms ecu ok
Yes I like that good idea Dave never thought of cutting it 👍
out of curiosity whats the reasoning behind that ?

idea of cutting is if feed is common to multiple components@@deisediagnostics629
5v ref code open when its short to ground , who writes the software for codes the new starter 🙃😄
😃👍
