Touran 1T '04 - Engine Warning Light - Possible Cause?

Hello,

I'm having a problem where our tour guide's check engine light has been on since yesterday. He also sees 'Exhaust system, please take to workshop' on the MFA.

I then ran a scan and cleared the error.
However, the error:
19558 - Motor for intake valve (V157): no signal
still remains.

I was then able to get the engine light to go out and drive away. However, after turning the engine off and on, the light came back on. I then cleared the error again, and the light went out. I then drove about 60km home. During this time, the fuel consumption/water temperature and performance were all normal. I then let the car run for a while at home in the hope that the fan would come on to test the function. However, this did not work. But the water temperature was only 87 degrees.

Now, my questions:

What do you think the cause could be? Since the errors all occurred at the same time, I don't think it's a component failure.

- Can I use VCDS to turn on the cooling fan to see if it works?
- Can I perform any other tests?
- Could I update or test the engine control unit?

I'm a little worried that if I take it to the dealership, they'll just replace everything and I'll get a huge bill.

Thank you for the tips!

Best regards,

Gerhard

Hi,
is this not already the answer:

However, the error is: 19558 - Engine for Intake Valve (V157): No Signal not to be lost.

The error is definitely related to emissions, and that's why the engine warning light comes on.

Hi,

Thank you for the tip!

Can this topic be linked to the cooling fan with the suction nozzle flap?

What would something like that cost? Is it worth changing it to 'suspicion'?

No, with the

engine for the intake valve

and its wiring.

Hello, Rainer

Both are connected to the same fuse: SB8 (engine compartment), if you have the High E-Box.

I'd like to check that out

Hi,

thanks for the tip about the fuse, how do I find out if I have the right one?

How is the intake valve actually, should it be defective, why don't I notice it at all while driving?


Greetings,

Gerhard

Regarding the High/Low box, I haven't looked at it. Just take a look at Fuse 8 and report back afterwards. It should also be mentioned in the flight log.

The three error messages also all fit: If the power supply voltage is missing, the signals can only be at ground.

Okay, let's check the fuse. If a high-box is not present: Check all fuses

Thanks! I'll do it tomorrow!

So, wie ist eigentlich der Zustand des Saugrohrventils? Wenn es defekt ist, warum bemerke ich das nicht beim Fahren?

The box is located on the driver's side next to the battery.
If the SB8 fuse is defective, it is 99.9% likely to be due to the control valve.

Check: Remove the cable connectors from the control flap, replace the fuse, turn on the ignition. If the fuse remains intact, repeat the process with the control flap reattached. If the fuse blows --> the control flap is defective. It's unfortunately just cheap plastic junk that's been installed. The problem, however, is well-known.

PS.: The cooling fan cannot be controlled without the SB8 fuse because, as previously stated, the fuse for the fan also does not have power.

Hello,

I'll check the car's fuse box tomorrow.

But I just found a PDF where my electrical panel is shown.

Okay,

It really looks like a suction valve.

I tested the F8 in the engine compartment, and it was actually broken.

- Suction tube valve cleared
- New fuse installed
- Engine started and stopped
> Disconnect completely

- Clogged suction tube
> Suction tube valve creates slight 'whistling' noises
- Engine started and stopped
> Protection by

Now I need to find a cheap new suction nozzle valve.

Thank you very much!

This part is made by Pierburg.

Thank you for the link!

I, however, have finally decided to buy the item today from the original. It cost 240€. Quite expensive.
Is it actually normal to have to register/sign up as a customer when buying parts worth over €100? I was quite surprised that I couldn't just get the part in a cash-only transaction. Unfortunately, the seller was unable to provide me with any information about the reason for the necessity.

I hope that I will be able to successfully complete the exchange.

EDIT: I also read on Google earlier that the new part might need to be programmed. Does it initialize automatically?

Thank you all for the great help so far!

I don't. I ordered the same part from Pierburg this morning -- significantly cheaper and with the same availability locally. I don't think it can be any worse than the part that OE uses. Furthermore, I do not want to support price manipulation any more than absolutely necessary.

If I can get a part from the same manufacturer as OE in the free market, then why would I bring their money to the pharmacist?

I haven't had any bad luck with it yet.

The reason could be the tax office. There is an obligation to record individual transactions, to the extent that it is reasonable. What is reasonable and what is not is a matter of individual assessment (when selling a used car, it is always reasonable; selling a loaf of bread does not need to be recorded individually).
Your friendly neighbor has set a relatively low limit of 100€. Maybe he just encountered a very strict examiner.

'However, it's also possible that the inventory levels were significantly depleted due to excessive evaporation, and there was a desire to have a bit more control over who sold what to whom.'

Hello,

Okay, now thankfully, the topic is finally over!

I replaced the part, and now everything is working again. The cooling fan is also working again. The error messages could be cleared... Everything will be alright!

I then opened the old part and discovered that a tooth on the large gear had broken off and was misaligned. This is why the current draw was so high. Also, everything was completely messed up

I should have just bought the cheaper part, as the original one was also made by the same manufacturer.


Thank you for the help!
