Vacuum Sensor Fail ?

[colchald]

Not as far as I know

Clear as day

SENT - Line High Voltage
SENT Sensor

So same sensor, just different fault code. Maybe sensor needs a clean ?

Give it a spin in the dishwasher

Clean the contacts I mean, not throw the sensor in a bucket of water.

It an accurately detect a fault when connected and then detect the disconnect ??

An Ultrasonic Detox is perhaps not going to promote change is my opinion ! Your car you the boss

What do you think the problem is ?
Simply a faulty sensor ?
When clearing the fault code it instantly returns.
The battery was apparently discharged & recharged at the dealership in an attempt to help the battery hold more charge, do you think this may have caused the fault code ?

 

[Dr Sheldon]

Often a new nut behind the wheel can alter the demographic !

You were also a new user once, learning from experienced VCDS users, and they were very helpful yes ?
I've done some more research on the fault code & mentions about the start - stop function.

Pipe with sensor

Cheers Crasher.

To be fair - Yes and No !!

VCDS came about around 1999 whereas my automotive career started near 2 decades before that.

I spend all day every day in a measured productive environment solving several conundrums such as yours each day. Not only VAG but any vehicle on the streets of London.

My car of choice is Volvo, don't have much liking for other marques other than the opportunity to earn handsomely when they fail. That there my friend is business.

You are able to easily research how often I ask for help on the forum.

More accurately according to the DTC that your module is delivering to VCDS. VCDS will read it and display it on your screen. VCDS plays no part in generating or choosing the the DTC. It is just a messenger.


That is quite likely a very accurate DTC and Description however a broken wire, poor connection may or may not throw the same DTC at you.

Worth checking in my book. MVB for Vacuum vs Actual measured Vacuum will guide you.

The failure you have is so common that the chances of it not being the Vacuum sensor is small, tiny ! Add to that you are not moaning about a hard pedal confirms that the Vacuum pump is working.

Replace the Vacuum Sensor, Wiring confirmed, then replace the ABS module if needed. It is that simple !!

Above in Bold and Red is help from me worth £120 an hour. Utilising it correctly and to the letter is guaranteed to help you towards a fix.


Based on the assumption that I am right, which I am, it was a little unsympathetic that you thought you could "Give it a Clean" and just poo poo my valid input.

Thank you for reading !

Hi Mate, thank you for your response. I just looked through all our communication & cannot find where me saying I'll attempt a clean of the contacts was poo pooing your input - sorry if it came across that way.

You were also a new user once, learning from experienced...

We were all new to the business at one time and had to learn.

In short, you have to create your own concept of work. Fault finding, checking, verifying, then repairing.

One idea is to borrow parts, if possible, from the same - working car, where the part is known to be good... If you are 99% sure that you have found the fault then you buy the original part and replace it.

 

[colchald]

Good Idea, Thanks Mate.
The vehicle is under a year's warranty & it's going in to the dealership on the 20th. Just wanted to see if I could fix it for free myself before that.

That's an interesting bit of background about you too.
Many thanks for the information in red too.
Ever watched Scotty Kilmer ? He's raving about an AI Mechanic App which I've downloaded as well.

 

[Crasher]

Scotty Kilmer is just “raving”, raving mad… his voice could curdle milk.

Ever watched Scotty Kilmer ?

No !

Very much doubt if he would have the level of knowledge that I have.
