The long minute of silence at the AHF, as it turned out this morning, was related to the fuel tank ventilation. Thanks to Ulf's article, I figured it out and I tried it without the fuel cap, and lo and behold - abracadabra.

I never thought we would hear about such an exotic case in the forum.

Did you ever notice any hissing sounds while solving the puzzle?
My mother's gasoline car is surprisingly good at this, even though it can take weeks to drain the tank completely before needing to refuel -> I'm always surprised that the car never complains about the low pressure in the tank.

How is your tank designed (with a lock or without, is there a visible vent)?

Day 2 after the realization:

This morning, no hissing sound, but the cold start problem is not completely resolved. The car starts worse with the fuel cap open. I'm actually considering replacing my "Knackfrosch" (a type of toy).

Hi,

After my CBBB took almost 3 seconds to start up for the first time the other day (and then immediately ran smoothly), I need to revisit this issue.

SSP 403 and 420 tell me something completely different than the operating manual (the latter, as before, states that you should wait until the light turns off. And the light takes approximately 2-3 seconds). What's going on?

Or did the marketing team once again prematurely launch the SSP while the technical team was still working on the user manual?

Quote:

SSP403: The preheating system. The 2.0 CR TDI engine has a diesel quick-start glow plug system. It practically enables an "Otto-cycle" instant start under almost all climatic conditions, without a long preheating time. Advantages: - "ottomotorischer" starting down to -24°C - extremely fast heating time (reaches 1,000 °C in 2s)

What they write in the SSP is often just marketing hype, but I'm telling you... 3 seconds from key on to the engine running is an instant start. The -24°C temperature only applies to the diesel fuel, which needs to remain fluid until that point. In reality, the temperature would likely drop much further.

If I hear the TSI engine starting early in the morning outside my house, I know what they mean when they talk about "ottomotorische Sofortstart" (instant start with an Otto engine) in the SSP (Specific System Program) .

Your specification of the duration of the pictogram's illumination matches the glow time specified in the SSP (Safety Data Sheet).

Thank you for your comment. From now on, I will behave and glow properly again.
I thought, with my unwavering belief in progress, that the maximum temperature must already be reached during the starting process...
You shouldn't believe everything you hear in marketing. Especially when it's clearly different compared to... Lower compression ratio likely also means less compression heat.

Regardless of any advancements, ultimately, all diesel engines ignite a mixture of air and diesel fuel through strong compression .

Roger,

Why are you glowing again now?
I didn't find anything in Deus' text that would have sparked my interest or excitement.

Since the BMR is already quite finicky to start, it always glows beforehand, so I wait until the Christmas tree icon has disappeared in the HUD. In addition, the tank needs every µA, so it's good if fewer LEDs are lit .

My wife always prepares the BLS by constantly leaving the lights on, essentially warming them up, to signal that it's about to start... ironically, she then gets rewarded with a real instant start .

Is the BLS generally a good cold starter?
If it's more likely to be no, then there might actually be something to the tip I recently read (I can't find the link anymore ):
Before a cold start, let the battery warm up slightly, for example, with a fully lit Christmas tree . The inevitable internal losses also warm the battery up somewhat, so that it can then deliver slightly more current under maximum load = engine cold start than a fully charged but deeply frozen battery.
Fairly speaking, the warning was included: if the batteries aren't in good condition, things could backfire.

Yes, the BLS is running really well – despite having 130,000 km (120,000 of which were in the first 20 months).

But since he doesn't have RLS, he always chooses LH.

Hi Martin,

As written, I had generally considered the pre-glow unnecessary after reading the SSP. However, since I had to engage the glow plugs for 3 seconds on one occasion, I became thoughtful and looked for an explanation. Because I tend to initially dismiss the "cracks in the ZK" problem, which has similar symptoms, I want to determine if it's related to a simpler issue, namely the glow plug function. And it's cold enough here at the moment for that (-5°C). Okay, so I'm going to follow BA's guidelines closely now and continue to monitor the situation.

Interestingly, the starter motor's speed is not at all affected by whether the engine was pre-glowed beforehand or not. And when it was running, it always started up immediately and ran smoothly, without any noticeable smoke or anything like that.

I had to consciously search for the filament in that forest of indicator lights.

Hi,

The CBAB (Cold Start Assist System) only releases the starter motor once the preheating process is complete... therefore, it is impossible to start the engine without preheating.
It starts up perfectly and runs smoothly right away.

Best regards, Rainer.

That's funny...

"Does it have a proper, old-fashioned ignition key?"
Do you have a Kessy?

Ignition key . The deposit slot was not worth the extra charge to me.

Best regards, Rainer.

"...since we've had a TSI running here, I've also been fascinated by its cold start. It starts immediately, but to warm up the catalytic converter, it does something that, in addition to causing a real odor nuisance, also makes quite a bit of noise." It should definitely prevent the rattling sound from starting and then scraping , and it didn't deserve a green sticker; it used to have a lot of "Russ" (unburnt fuel) in the exhaust .

The ASZ still starts without preheating... now two glow plugs are broken and the battery is almost at the end of its life, so there is definitely a double need for action . New glow plugs need electricity... so I need to deal with that if it doesn't want to start anymore .

Two weeks of inactivity in the garage, this morning the temperature was -7.5°C. I put the key in, turned it, and despite the very sluggish starter motor speed, the engine started immediately. Everything remains the same, as it always has been .

@ matthiasTDI96: The 1.4 Golf VI also smells terribly shortly after a cold start.
Thick fog was drifting over the administrative parking lot earlier. Here's a translation of the text "Dazu ein Aroma zwischen":

"In addition, a flavor somewhere in between."
Cleaning solution fumes, rotten eggs, and stiff sponges...
