Hi everyone, I washed the car engine, even though my speedometer works at the beginning, it does not work at the moment. Fuel gauge fluctuates help please.

I washed it last month :(

When you say 'washed', what exactly did you do? Can you also let us know what car you have?

'Yıkanmış' dediğinde tam olarak ne yaptın? Hangi arabanız olduğunu da bize bildirir misiniz?

2008 fabia tdi

my english is bad i'm sorry

There was an oil leak.  I washed the engine

they wrapped the brain in sachets

Pressure washed? The brain? The ECU?

Check all the contacts or wait until the water has evaporated.

Yes pressure. Yes ecu

1 month has evaporated water. I removed the speed sensor and cleaned it

That's not going to help you much if water got into a multiplug and corroded one or more of the contacts.

I sprayed the contact spray in the fuse box. Where else should I look?

Have you got a fault code reader / VCDS. Check the DTCs. This may help locate the problem more. It probably is corrosion or maybe even short circuiting.

no vcds

😞

No error code with obd

I want to measure the sensor.

where is the sensor?

Which sensor?

Hangi sensör?

Speed sensor

Speed data comes from the ABS controller which collects data from the wheel speed sensors. Those are in the wheel hubs.

I want to order a new speed sensor.

but it says only pa66-gf30 on it

How can I find the sensor code?

There isn't a single speed sensor on your car. Like I said above, the speedometer gets speed information from the ABS controller which collects speed information from the four wheels using sensors in the wheel hubs. This is almost certainly not the problem with your car. Most likely, water has gotten into one or more electronic modules in the engine bay and damaged them. You are going to need proper VAG diagnostics and a skilled auto-electrician to fix this. There is no cheap or easy fix here.

what is the sensor on the gearbox then I'm confused?

A dummy speed sensor. Plastic thing? Unplug the cable and look at what it goes onto, no electric connections?

yes there is an electrical connection.  This is a speed sensor on the gearbox.

6Q0919149A may be exactly the same as here I don't know my code

Please read again what I wrote.

Look at the part that the electrical connector goes onto. Are there any metal bits?

If it looks like this, it's a dummy sensor. Inactive.

 

I replaced the speed sensor on the gearbox.  the problem has been solved thank you for your help.

Oh, OK. Does the car not have ABS?
