Wie oft glüht Ihr bei Kälte (?? - 5°C) vor? - PD, CR und VEP | Posts 64+

...well, the TSI is a "problem child" and a "cold start nightmare" . That's what happens when a gasoline engine tries to emulate a diesel .

Okay, the first attempt at a BLS cold start film has failed.
One has to do it oneself .

Outside temperature is approximately -6°C. Both vehicles were used for city driving yesterday.


Wow... the BMR (presumably referring to a machine or system) started up with a jolt, like a 9-cylinder oil tanker.
He worked his way up to the correct RPM very reluctantly, then it took 2-3 attempts to start, and then it ran well (with the idle speed adjusted upwards by me).

Could the knocking sound possibly be caused by previously very wet combustion chambers and uncontrolled afterburning of the previous injections? Like what happens when you start with Startpilot?

The 1.4-liter engine mentioned above is not a TSI engine, but rather the base engine.

PD (ASZ): Pre-glow after filament heating in the ignition coil.

CR (ASB): Pre-glow after filament heating in the ignition coil. Starts easily, either without or with a shorter preheating time, and is also very responsive.

VEP (AXG): 2 times pre-glow using the heating element in the control unit, waiting for the relay to switch off during the second pre-glow cycle.
However, with that particular model, the starting problem is likely due to the fact that it doesn't start very well when the temperature is below 5°C.
Most of the time, the engine is preheated by the auxiliary heater, which allows it to start perfectly without needing to be glowed.

Thank you for your active participation . I'm curious, we're apparently going to get a "Russenwind" (cold wind from Russia) here for Christmas, which will bring temperatures down to -25°C (!). Here's where it gets interesting to see what the AHF says . I'll definitely be adding flow improvers beforehand (NO, not gasoline! ).

Damn.

Yesterday (-6 degrees Celsius), the BLS started up like a dream, just like today, and the BMR almost didn't make it.

Today's picture: (-2 degrees Celsius and covered in snow).
The BMR sounds like "give me a new battery," but even with the different batteries I borrowed from a 3C BMP in the spring, it didn't make a difference.

Nice idea with the videos. Are the photos directly uploaded from the digital camera, or did you convert them in any way?

By the way, since I started preheating, my CBBB (presumably a piece of equipment) now consistently starts properly on the 4th rotation. This morning, the temperature in the parking garage was just above 0 degrees Celsius, but after approximately 3-4 seconds of preheating (after a standstill of about 12 hours).

Canon IXUS 75 -> using "Free FLV Converter" to convert to .flv -> upload.

Rainer modifies the .flv files so that they can be directly displayed with a player, etc.
I noticed that I had chosen an unfavorable combination of pixel size (large) and bitrate (low), which is why the result ended up being a bit grainy.

I'm going to plug the BMR into the charger tonight (using the permanent power connection of the trailer hitch) and see how it reacts tomorrow.

My love message from yesterday is no longer displayed. I borrowed and installed a used battery. It started up and seemed to spin a little faster, subjectively. That was all there was.

The exchange wasn't that simple - hopefully, no one will accidentally disconnect a battery terminal. The French marble reacts very negatively to that! However, the low standby power consumption could be met by two measurement cables, which ensured the power supply during the replacement process.

Should I really buy a new battery (must I)?

Perhaps the used battery was previously warm? If so, that would explain the difference. To be sure, you might want to connect it to a battery tester.

@dieselmartin:
Thank you for the information. I now have an S95 that is capable of recording video (720p). I might need that someday.

Warm is an exaggeration. I took them out of a BMW that was parked in a garage. The garage, like mine, was unheated and probably only a little warmer than the outside temperature. So, that battery was also "warm," but it's just a few years younger with a comparable capacity (92 Ah removed, 88 Ah installed - I don't remember the starting current off the top of my head). Furthermore, it had already been installed in the Peugeot overnight, and this morning it finally got to show what it could do...

I don't have a battery tester. I only measure the voltage "cold" after a long period of inactivity. It should be around 12.4 - 12.6 V. If it's underneath, then at least one cell usually has a problem.

I have a healthy degree of skepticism about the battery testers used in workshops. Not to the testers themselves, but to the merchants who set the specifications for the mechatronics engineers and want to bring batteries to the public.

You shouldn't let someone else test the workshop; you should do it yourself .
Without a load, the increased internal resistance of an aged battery is not taken into account.

How much load is needed?

Typical values are 100A.

.. so a 70 Ah battery would then be completely discharged after 42 minutes.
