So long story short I changed my oil today, went everywhere with the wind

Started my car and all good then all sorts of errors, tyre pressure, hill hold, afs, auto hold maybe some more

I then thought hmm maybe it’s because I left the bonnet open for a while and battery somehow low but nope that’s all good.

I then ran a vcds scan and loads of errors but one of them was “Rear Left speed sensor” (I assume that’s passenger side in UK)?

I was thinking hmm that’s still odd but then I remembered when I lowered the back from the ramp I forgot to remove my bricks, I didn’t want to start the car yet so I smacked the bricks out from under the rear tyres with a hammer, took a little bit of hitting but nothing too drastic.

I just took the rear passenger wheel sensor off, looked alright but gave it a clean anyway, put it back but same errors soon as I go round a corner

So I guess I’ve buggered the sensor and need a new one? But not sure if rear left is as you look at the car (driver) or when your inside the car (passenger)

Thanks

Left as experienced when sitting in car facing forward. So nearside in UK.

It’s also possible, given the number of error codes that it’s somewhat coincidental.

Did the oil spill everywhere in the engine bay? Possibly in any fuses etc?

Because that amount of sudden onset faults sounds like an electrical short

1. Don't use bricks instead of coach stands or wood blocks. Bricks can crumble unexpectedly, leaving you supporting half a car on your chest.

2. You may or may not have broken a sensor probably the LH rear. First suggestion is to use a code reader to reset the errors, and see which, if any, recur.

I did reset the errors but they came back straight away pretty much

I do need something better than bricks for sure!

I went for a drive with all the errors and plugged in vcds, setup the measuring blocks and all reading values apart from rear left

So hopefully it’s not something else and just a sensor replacement needed, seems fairly common and I guess smacking the brick out of the way has killed the sensor

Lessons learned n all :(

When I cleaned the sensor yesterday I forgot to get the part number so whipped it off today and it’s WHT 003 864 A

Ordered this from GSF https://www.gsfcarparts.com/products/wheel-speed-abs-sensor-75mm-rear-za051624?auto_apply_coupon=ROAD24&srsltid=AfmBOoqYllvwULKbcK-U8VCusIxo4k0OhNSVqU_V5hV-vSlKZYdLQEjqy1M

Thought I’d go with Hella and the cross reference says it’s compatible with part number from mine, so fingers crossed it’s just that and coming here Tuesday

Will report back

Certainly looks like the sensor has failed. It was the NSR which failed on ours a few years ago, lighting up the dash and bleeping like billyo.

Just replaced the sensor with this

And jobs a goodun all working fine, started the car and had errors but drove a few meters and they all cleared.

Will do a proper vcds scan and clear later but working a treat
