Are T5 glow plugs monitored by the control unit?

My T5 has been taking longer to start recently, and the north-west position sensor will be replaced soon.

Are the glow plugs monitored via diagnostics in this vehicle, so that a warning is displayed if one is defective? Or do I need to disconnect the VD (voltage divider) and measure it manually?

Is there also a software update available for the control unit?

Thank you!

End.

You can measure these here using a test lamp. They are installed externally. I'm not entirely sure if they will be displayed in case of an error, but I suspect they will.

According to the scan, he needs a new battery.

Wow, I just saw it.

Okay, I'm ready. Please provide the German text you want me to translate.

Can you access that without using the T5 service port?

Yes, but the spark plug connectors are already quite tight.

Hello,

Yes, the glow plugs are likely monitored, and any related errors are stored in the engine control unit. You can try disconnecting a connector from a glow plug as a test.

Starting problems when the engine is cold are often caused by air in the fuel system or a faulty coolant temperature sensor (sensor block 7 in your engine control unit) that reports temperatures that are too high.

Best regards, Rainer.

Thank you for the information. It's now also happening more frequently when the engine is warm.

Okay, I'm going to replace the camshaft position sensor (G40) now.

Uh yes, of course, that could also be the cause (forest, trees).

It can happen sometimes.

"I noticed that the NW Simmering seal also appears to be leaking. Is there anything I should be aware of when removing the seal?"
"Position of NW?" Is it sufficient if the notch is at the 4Z position?

Have you already wiped up any oil from there? It looks more like a leaky valve cover.

Another question I've seen is that the NW Simmering seal is also slightly leaking. Is there anything to be aware of when removing the disc? "Position of NW?" Or is it sufficient if the notch is at the 4Z position?

The NW (presumably a component) should have a groove for a Belleville spring. I assume that such a groove is present. Mark everything carefully, just in case.

Yes, it's also possible that the valve cover needs to be checked at that mileage.

I mean, the hub must have some kind of notch or reference point that the wheel speed sensor measures, and then sends the signal to the control unit.

Do you not replace the crankshaft seals at the same time when changing the timing belt? Or, how does VW do it?

That's a tricky thing. If they are made of Teflon and are sealed properly, I won't replace them.

The problem is that the sealing lip gradually works its way into the northwest direction over time.
To put it exaggeratedly, it creates a benefit.
If the new sealing ring isn't positioned exactly in the same place, you've created an oil pump... And who's the fool then?

With the older Simmering rings (with felt seals), there were sometimes different designs featuring offset sealing lips. That allowed us to circumvent the problem.

However, I wouldn't want to generalize that. There are also cases where this happens without any problems, or where there are no signs of intrusion.

Hello,

I believe the glow plug monitoring system was only introduced with EURO 4 or MKB Bxx engines – it wasn't present before, at least not in my two vehicles. Golf with BKD (EU4): YES, Treg with AYH (EU3): NO.

I might be wrong, though...

Sure, here is the translation of the text from German to English:

"1 error found:"

P3007 - 000 - No signal - Intermittent.

I would also take a look at it if it didn't start so poorly.

Have a nice day.

1. There are also EU3 engines with glow plug monitoring.
2. There are EU4 engines with the MKB Axx .

My AXR, for example, is a EU3/D4 engine, because the EU4 standard didn't exist at that time (but it's still treated like an EU4 engine...). Green sticker without filter ).
Later AXR versions are definitely encrypted using EU4 methods. The biggest difference compared to mine is the MSTG, which fully supports the E-OBD2 functions.
Both monitor the function of the glow plugs in the engine control unit (ECU). However, even the predecessor of the AXR (the ATD) had this function, and that was a pure EU3 engine.

Thank you for the information!

One spark plug was defective, but it was not identified as defective by the maintenance team.
The candle had a resistance value of 1 kOhm.

Interesting. Could you try unplugging a connector and see if any errors are logged?
