I had this on an Audi A5, it stated as brake system pressure fault. Changed this pressure sensor and it made no difference, did more checks on the vehicle, and it was a fault inside the ABS pump assembly itself, removed the complete ABS pump and sent it away to specialist to recheck the fault.. pump was repaired and it cured this fault.

[@diydaly]

👍👍 we got the pump done first, fixed 80% of the problems but was left with this

[@alexdurant6914]

What was the total cost

[@ariantaria2065]

Easy diagnosis Easy fix. as always your videos very informative

[@diydaly]

👍 thanks mate

[@ihtishaamkhan1425]

Great video!! I had a brake servo warning appear in my Audi A5, bought the part from your link and it fixed the issue. Thanks

[@diydaly]

Glad it helped! Thanks for the comment 👍👍

[@stephenmullan9973]

Did the error clear from the dashboard after you replaced the part?

[@ihtishaamkhan1425]

It did, but the auto stop/start warning didn’t go till I drove it for a bit, stopped the car and locked it. When I started the car again, all warnings disappeared.

hey mate great vid, ive got this come up on my A5 including tyre pressure warning, if i replace the switch how do i reset the fault? will it need a topdon to be plugged in to reset? or is there another way

[@diydaly]

You’ll need a scanner that will read the ABS ecu , there are quite a few cheaper alternatives that will do it

[@GG-eg6kn]

What’s the long number on the sensor under the part number?? Does it matter if the numbers don’t match? I can’t seem to find one that starts with 160 like mine does

[@TheDervMan]

What was broken in the ABS pump? Great to have ‘Don’ back 😎🎉

[@diydaly]

👍👍 im not sure exactly but I think Its something in the ecu section that fails as it causes mainly communication issues

[@aligizzle69]

Any tips on how to click the new one into place. I’ve tried and tried but I just cannot get it to click into the actual pressure valve

[@diydaly]

Sounds odd should click in really easily

[@castrolgtx5064]

Will the TopDon reset the service interval on that 2017 Audi?

[@diydaly]

Yes mate , did both the oil & inspection lights with it 👍

Not sure if anyone will read this message seeing as this post has been posted a while ago. I had C11EC04 code come up and took the car to Audi and they informed me that I could continue to drive the car and the car would have to be brought in for diagnostic )(£192 / hr) and fixing. After a few days of driving the car as I wanted to take it to a mechanic friend of mine for a second opinion, the second error came up and it now seems the ABS module is bricked !! Audi has a responsibility here as the alert should not be stating: "You can continue driving" How many people have contested this at Audi ?? Surely there is a class action here.

[@trevormansfield6495]

good info again. Cheers

[@diydaly]

Thanks trev

[@callumschooly6395]

Thanks for the great video, this fault just cropped up on mine. I clicked the link for the genuine OE Sensor but the link has expired, could you send the new link by any chance? Or shal I just get the Aftermarket as that link is working. Thanks, Callum

[@diydaly]

Hi Callum ! Sorry for the late reply! I’ve got a few links that need updating .. hope you got sorted , I’ll try update soon

[@callumschooly6395]

@@diydaly I bought the after market part, installed it as per your video, and ‘touch wood’ the fault code has gone. Thank you soo much for the Video. Saved me £320 as quoted by the Audi Garage 🙏🏻

@@callumschooly6395 arr nice one , glad to hear it 👍👍

Hi i have one question as a Audi A6 C7 Owner . My start stop failed at a bump and it turned off the car then a message displayed Start Engine Manually saddly as an idiot i didnt see that the car was in gear and it couldnt start , i pushed the car to the side of the roadit displayed meessage Brake Servo Failure or smth like that , i put the car in gear and then i turned the car off and on and the message dissapeared , should i be worried?

[@diydaly]

Never really come across that tbh mate , may be best to get it checked out

[@shahsufyan2749]

Can you still drive with this sign on ? This sign just came on this week and I've changed the brake pressure sensor but the sign is still there any help would be great

[@diydaly]

Have you cleared the fault codes? If it stays on you may have a faulty abs pump or possible diffenet issue

[@shahsufyan2749]

@@diydaly I didn't clear the faults unfortunately.. is it dangerous to drive like this sorry for my ignorance

[@diydaly]

shouldn't be dangerous but you will need to get them cleared @@shahsufyan2749

[@waynewilson3871]

I HAD THIS ERROR AND IT WAS BECAUSE I PUT BIGGER PROFILE TYRES ON MY CAR! I REVERTED TO OLD TYRE SPEC AND THE FAULT WAS CLEARED! VW Polo tsi 1.0
