P38A ABS & TC lights

Tempted to buy these and fit some grommets where it needs to clip up if 400mm is long enough - Wabco

Nope needs to be 1090mm and doesn't work on a 60 tooth reluctor ring

From memory, that's not long enough.
I have a spare pair of cheapy ones that I can measure for you when I get home if you like?

Bet they are made in China

Just ordered a couple of cheapies for the rears they already sent out the wrong ones last week so don’t bode well will post when fitted and tested

I'm confused now, reading the above. Do you still need measurements?

My experience with aftermarket sensors differs from Datatek's, in my experience they have lasted anywhere between 1 month and 6 months a piece. God knows why as there are no moving parts to wear out. They all have ended up going open circuit sooner or later. Its only a magnet and a coil inside.

Hi there, no I don't - I've measured an old front one and its 1090mm but the book says 1100mm. I guess they are measuring from the tip of the socket to the centre of the stainless steel casing.

Good post. I dread mine failing. I've had them out a few times but they're original and now 27 years old ... the old ones are the best!

Here’s the old one end looks knacked to me the originals are about £450 a pop

Mine would have still been working fine 22 years later if I hadn't had to destroy them to renew the bloody balljoints after the MOT fail. The only thing I can surmise is that the coil windings must break easily on the aftermarket ones if the sensor measures zero ohms with a multimeter - maybe the cheapo coil can't cope with prolonged vibration - there's no excessive current or voltage to burn it out.

Fronts are £190 each nowadays - crazy price

Replaced the rear right sensor have got a new one for the left if needed but still getting abs traction lights on dash here’s the latest lot of results but nanocom says no faults

Now seems the fronts aren’t picking up any wheel speeds one new sensor on front aswell cheers as to where to go now

No errors? Pushed all the way in?

That’s what the nanocom says I can’t work that out there must be errors somewhere

Never used a nanocom but why is it reporting vast differences between wheels in wheel speed ?

Well it was now nothing on the fronts will wait for rain to stop then go and push fronts in bit to make sure
