and another status update:

Despite the battery delivering decent values, I almost had to be towed yesterday .

When starting the engine, the starter motor turned about 2 times and then stopped working as if the power suddenly cut out. Although the battery seems to be okay, it doesn't provide a satisfactory result after 24 hours of inactivity.

In addition to the new battery, I will also slightly increase the fuel injection amount; I expect this to result in a small additional improvement .

Hi,

Have you checked the wiring, as has been asked repeatedly? I experienced similar strange phenomena after a visit to the workshop, where the professionals had not properly tightened one of the battery terminals.

Best regards,

Jan.

I have found the cause

See newspaper article: http://www.badische-zeitung.de/freiburg/falscher-sprit-in-zapfsaeulen-weitere-geschaedigte-melden-sich--93754204.html

I'm going to take the car to the nearest VW service center so they can take care of everything. What exactly should I tell them to pay attention to? I mean, for example, regarding coolant loss.

Do you believe me that I myself had thought of this case, but had considered it impossible?

Hi,

Unbelievable... this is already the second case of its kind (the other one was probably bigger and discovered faster, but it made it all the way to Spiegel Online) in the last few weeks.

Best regards,

Jan.

"I wonder if it smelled like gasoline?"

How much gasoline did you put in, or how much diesel was left in the tank?

Possibly, I would consult a vehicle expert.

Even if the vehicle appears to be running correctly after cleaning, there is a risk of potential long-term consequences from the PDs.

I spoke with the gas station attendant.
According to their analysis, the diesel pump contained 8% gasoline.

I filled up a total of 51 liters of fuel, which is approximately 5 liters of gasoline.

On Friday, I have my first appointment, where an initial assessment will be carried out. Afterwards, there will likely be a second appointment with an expert from the insurance company – the workshop also confirmed this procedure.

More information will follow .

Am I mistaken, or is it permissible to add up to 30% gasoline to the fuel tank for winter operation (=as a substitute for winter diesel)?
If I'm not mistaken, the engine shouldn't exhibit any problems when running on 8% gasoline.

You are the injured party. At least in the case of comprehensive insurance claims, you have the right to choose your own appraiser. If this also applies to this case, then I would under no circumstances accept an appraiser from the opposing insurance company. An appraiser always acts to some extent in the interest of the client. Especially in cases of damage that are as unclear as yours, where the engine starts again after a fuel change, there is a great risk that you will initially only receive compensation for the actual fuel costs plus any workshop costs incurred so far.
When you choose your own expert appraiser, you have a much better chance of getting an appraisal that is favorable to your interests. This could potentially include new findings regarding factors like fuel consumption or lifespan, or at the very least, a significant reduction in the appraised value.

Therefore, I would advise you to find out as soon as possible whether you are required to accept the opposing reviewer, or whether you have the option to choose your own reviewers.

Greetings.
Guste.

Actually, it's not surprising if the 13.7V you mentioned earlier, while the engine is running, is correct. Because a battery is only properly charged in the range of 14.2 - 14.4V.

13.7V is quite low, even for the maintenance charging of a fully charged battery. If a battery never receives a charging voltage exceeding 13.7V for months or years, it is likely not even half-charged and may already be partially sulfated, meaning it is close to being unusable. Therefore, I would strongly recommend checking (or having checked) the charging system, specifically the alternator and the charging path to the battery.

However, modern injection systems like PDEs cannot tolerate the use of leaded gasoline additives anymore because they then experience problems with internal lubrication.

Today, I went to the VW dealership. After a lengthy discussion, including with the lawyer representing the gas station, I am now required to submit a cost estimate to repair the damage.

I asked the workshop to include a note on the cost estimate stating that consequential damages cannot be excluded, as a certain number of kilometers (approximately 6-7,000) were driven after the date of the estimate.

On Monday, I'm getting that great item. Would you like me to post it here?

Okay, here's the translation:

"The process continues... I was denied a cost estimate because potential consequential damages cannot be ruled out... I am now in contact with the insurance company and have suggested having an expert assessment done."

Thank you for the feedback. Please keep us updated. It's an interesting case.

Greetings.

The matter isn't completely off the table yet - there's now something "concrete" happening.
I dropped off the car at to get an inspection report. They kept the car for 4 days.

However, the day before the appointment, I received information that only a cost estimate could be prepared, not a full expert report.

Done and said - here's the cost estimate.

I've done some further research, and as soon as I have concrete information, I'll share my analysis here.

.

It would be conclusive evidence if there were now a defect or flaw, the cause of which could be attributed to the gasoline additive... ... that's how I see it.

This deficiency would also need to be addressed.

A term life insurance policy only pays out upon death, not upon a later event described as "death not excluded."

correct, which is why there are ""

However, I do have some serious criticisms:
- Poor engine starting.
- Erratic idle.
- Severe jerking/shaking from 4th to 6th gear (during acceleration).

Everything points towards PD coking and leakage.
I have now ordered an ultrasonic cleaner from EMAG. The PD elements will be released next week, cleaned, and reinstalled with a new seal.

Should I ideally replace the tips? It's probably not possible to really assess their condition before removing them.

I believe that no insurance will cover damages in that specific case.

There must be demonstrable damage caused by a lack of lubrication. The workshop is responsible... and possibly an expert who can confirm this.

Everything else is speculation.

My intention is to replace all the PDS units. The rest of the fuel system should survive the addition of the additive.

Basically, you're absolutely right - I'm hoping for a little more understanding from the insurance company.
These were approximately 30 vehicles in total, all of which incurred similar costs. In some cases, there were common-rail systems that resulted in expenses of nearly €8,000.

I'm just sending it now and will see their feedback.
