Hello Rainer, the T6 has 170,000 km on it and is 4 years and 4 months old. The AGR cooler was replaced free of charge. The clogging of the heat exchanger is supposedly due to coolant G 13. Greetings Wolfgang

"Where does this statement originate, claiming that the cause is the coolant additive?"

Hello forum, a workshop manager hinted that the T6 model has these problems more often. There are also reports on YouTube about the G13. Best regards, Wolfgang.

So, it turns out there are indeed some irregularities. That's why I started this thread.
Okay, I'm ready. Please provide the German text you want me to translate.

Bad, maybe replacing the coolant wouldn't be a bad idea...

"Hello everyone, I was at my parts supplier – a large company – and picked up some spare parts. I told the salesperson that I was returning the G13 coolant for my T6 because the heat exchanger is clogged, and I'll be taking G12++ instead. The salesperson said he was surprised I was buying G13, as there was a VW campaign advising against its use. However, there's no clear instruction, with some workshops using G12 and others using G13. Talking to salespeople at wholesale suppliers is better than any training at VW. 200 workshops that have to repair this mess after the warranty period know more than the poor VW mechanics." Best regards, Wolfgang.
