DIY - ABS Sensor Replacement (on any car)

Skoda Superb 2012 1.8TSI MT - Change ABS Sensor (on any VAG/AUDI/any car) myself and SAVED 6000/- bucks

So last month on my Moradabad road trip I got this on the dashboard and a whole lot of error lights flashed up (as visible) -

While the car was driving absolutely normally, I feared it had something to do with the ABS sensors, which btw is a very common issue with VAG cars. So I drove down to my sparsely maintained Skoda workshop at Meerut, Brite Skoda (they were operating the workshop only 1 day in a week due to some logistics issue) and got the car scanned. The FRONT LEFT ABS sensor was found to be the culprit issue in the scan. As they didn't have the part in their stock, they told me to come next week for replacement and quoted me a princely sum of Rs. 7~7500 bucks for the job (5200/- for the part and rest labour). I contacted a local parts dealer and he said he could arrange a EU manufactured OE part at just 1200 bucks (I could have got it for around 900 bucks from Delhi). So I ordered the part, which arrived next day, and decided to tackle the job myself after seeing some YouTube videos.

This video was helpful -



The car was jacked up to remove the front left wheel -

And properly 'double secured' before proceeding -

The job was possible even in the narrow workplace I had -

Here's a view of the culprit ABS sensor secured by just a T30 bolt -

I couldn't detach the top connector as it was too tightly attached. So I decided to remove the T30 screw directly with the connector attached and tackle the removal of the connector with the ABS sensor dislodged (which worked out more convenient). Here's the ABS sensor. When I removed it, it also had a long line a dust at the tip (not visible in the photo as I had cleaned it by then) which in fact could be contributing to the magnetic sensor not relaying the information correctly and the sensor might just be working perfectly -

There was also a lot of gung in the chamber where the sensor is placed which I cleaned out later with Brake Cleaner (which is basically just compressed IPA) -

A closer look at the now cleaned ABS sensor -

And the connector pins inside -

The removed connector. Also notice the now cleaned ABS sensor slot -

A closer look at the locking tab on the connector and the direction it needs to be moved to be unlocked -

The new 'Made in Romania' OE replacement part -

The old and new parts together. Exact same part # was embossed on both -

I also checked and confirmed that the connector was receiving the 12V current by switching the ignition on so as to rule out any wiring issues -

11.6V being received with the ignition in on position and car off -

Also came out my handy anti-seize lubricant and Di-electric grease -

DIY - ABS Sensor Replacement (on any car)-skoda-superb-abs-esc-error-20112024_19.jpg

The anti-seize was applied on just the grooved part of the abs sensor while avoiding the tip as stated in Skoda's workshop manual -

And the Di-electric grease was smeared in very little quantity on the connector's contact points -

I did not have the time to test the old sensor after cleaning (I am 90% sure that it will work perfectly after cleaning) and just went ahead with replacing this 1200 bucks part with the new one -

Secured the T30 nut back in place and tightened very slightly (OE recommended Torque is just 9nm) -

And re-attached the connector, hearing a click, back in place. Job completed (after re-attaching the tyre) -

On 1st start after the job, the error and the warning lights still appeared on the dash, but they went off after driving just 10 meters. All warning lights and error messages off and things back to normal -

A nice saving of 6000 bucks for a 30 minutes job.

Re: DIY - ABS Sensor Replacement (on any car)

This is a fantastic DIY tutorial for anyone wanting to get their hands dirty on their cars! Thank you so much the the write up. If an abs sensor replacement can be this easy on a German car, I'm sure many people would be willing to work on their own vehicles which are bound to be easier than this.
