Golf IV - Temperaturanzeige funktionslos: Wo suchen? | Posts 16+

VW often uses double-sided heating elements.
One for AI, one for MSTG.

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

It should have at least given some kind of error message, considering how broken it was.

The offered PIN codes are well-intentioned. However, I'm not planning on coming to the meeting in a car, and "he" certainly won't give it to me. So, the repair will either be done here or he'll do it himself.

Why are these things blooming so poorly? The sensor itself is sealed and completely dry. Oh yes, the connector has four pins.

Why not? If it still worked for the MSTG. There should be an entry in the AI system.

I already knew you wouldn't be able to make it for the golf outing. I just thought you might need the PIN codes, which I could have brought along.

The commercially available connector is then just the housing without the pins? If so, I would like to know the part number.

Otherwise, it could also be a suitable connector that was cut off somewhere and still has about 5-15 cm of cable attached. I would solder it on, put a shrink tube over it, and that would be fine.

With my OBD controller, I couldn't connect to the Golf IV: "No response from the control unit." Newer VW models were at least accessible based on the data that needs to be read out during the vehicle inspection (HU).

That's correct.

What does the connector look like? Is it round or square?

Hello everyone!

The Ibiza has so many wiring harnesses and connectors lying around, which he has already praised extensively.
...he would also come to the meeting.

Best regards from Munich!

I need to check again. But I think it was square-shaped.

You could politely ask the Ibiza.

You could already find that in the Golf 1 GTI back in 1976, and it even had 9 more horsepower.
Unfortunately, these engines were often unfairly criticized and dismissed without proper consideration.


In the mid-1980s, Peugeot even managed to extract between 105 and 115 horsepower from a 1.6-liter XU5 engine in the 205 GTI. And those engines were incredibly reliable.

Bertil, that's certainly true! Sometimes one is blind...

I can only roll my eyes at the 68 horsepower that are squeezed out of my diesel-powered "flying saucer" with turbo support.

B.t.w.: My toy Saxo also has 118 horsepower from a 1.6-liter engine, although it's a 16V. I suppose I should start preparing it for winter soon. However, it only managed to cover just under 3,000 km this summer.

Oh dear, now I have to spend money. So, what is the part number? With hose clamps? With new connectors, what will be needed?

If you talk to me, I'll check in the warehouse.


Be glad if it's just the crankshaft position sensor. In one Opel Agila I had, the oil pressure switch malfunctioned and sprayed oil backwards – about 2 liters of oil came out, right at the contact point on the back of the connector.

And for the installation, they kindly allowed you to remove the bumper and various cover panels, making it somewhat manageable even with broken fingers. It was especially amusing when everything was oily, and you weren't allowed to wash the engine beforehand because you were doing repairs at home.

The four-pin connector for that temperature sensor is being sought. It's likely a square shape. I'll take another look at it on Tuesday.

"My colleague really cleaned and polished everything up over the weekend. Apparently, the contact pins on the sensor are sparkling clean, and he seems to think he might have even disassembled and cleaned the connector. Whatever the case, I wasn't there, so I didn't see it. In any event, your contributions were helpful, and I would like to thank "Wiesel" again for the assistance provided via private message."
