We also experienced this - the most permanent solution is to completely replace all the wiring, from the accelerator pedal to the engine control unit (ECU), ensuring a continuous and secure connection! We initially replaced pins here and there, but it didn't solve the problem; somewhere, there was still an issue. We ended up replacing all the wiring from top to bottom, and we've never had a problem since.

Thank you very much! But how much do all the new pipes and the installation cost approximately? It's not going to be cheap, is it?

Okay, I think it will probably take the workshop about 2-3 hours. They'll need to remove the interior trim from the footwell, disassemble the water tank, and run the cables from the footwell to the control unit, then reassemble everything.
You won't find a corresponding wiring harness, unless you buy a complete one, which would be ridiculous. So, you'll need to add some extra wire and a few pins for the engine control unit (ECU) and some more for the accelerator pedal.

I don't think it should cost 300 euros; it's probably cheaper at a smaller, independent shop... or you could do it yourself.

Or, as mentioned above, actually searching - the problem we had was that the separation point, which still existed in the electrical diagram, was not marked, and supposedly there were continuous wires from the module to the control unit (STG).

And can you tell me where I can find such a wiring diagram? It would be very helpful!

I'm still quite inexperienced with a Passat, I've only had it for a year, and it would be a shame to sell it! But is it repairable? Because I've almost given up hope!

Everything is repairable . With the necessary money and the unwavering will - how else would we still be enjoying classic cars on the road today ??

You might be able to get a printed copy of the SLP (Safety Data Sheet) from your supplier if you ask nicely, specifically for the section that's relevant to you.

Okay, thank you very much!!! You were a great help to me! I'll try to go to the workshop tomorrow or the day after, and if everything works out, I'll have you to thank for it! If not, there's nothing you can do about it, and I'll be back on the forum. Or: *gg*

Hi, I think I've found a possible cause for the recurring problem. Today, I felt with my hand in the upper footwell area and the fabric was wet. I lost the underbody cover for the engine compartment on the highway, and I think that's why moisture is getting in! Could that be it? Or is the moisture coming from somewhere else? Is it even possible for moisture to get in there? And how can I prevent moisture from getting in? Where should I seal it? Recently, after going through a car wash, I also noticed that water is dripping from the light switch! Could it be coming from the sunroof? Is something perhaps blocked or leaking? I'm afraid to go to the VW workshop because I'll be broke soon.If it continues like this!

"With TDI engines, there's a problem with the brake light switch. When braking, the control unit receives a signal and automatically reduces the engine speed."

It costs 600€ for troubleshooting and replacing the wiring harness that runs from the throttle position sensor to the control unit.
That was calculated by the VW insurance company.

Please check if the drain near the control unit was cleaned during the last inspection. My friends don't usually do that, as they claim that point was removed from the inspection checklist. I had a similar issue before and wondered why it was clogged, especially since my car is mostly parked and used in a garage (I was recently at the workshop, and they might have forgotten to verschandeln it or something).

Then there was a case where, somehow, liquid from the car wash ended up on the potentiometer, and it had the same error.

As I mentioned, I found the fault at the connection point between the throttle position sensor cable harness/connector and the engine control unit cable harness/connector.
While everything else has been replaced, the faulty side of the connector wasn't renewed, so it continues to corrode and exhibits the same problems.
I haven't had that error for 2 months now.
I complained to the workshop and also consulted with a lawyer.
In the end, I negotiated with the boss for a complete inspection, timing belt replacement, brake hoses, and a replacement car, which I'm getting as compensation.

Best regards.
