Hi with the ABS, Tire pressure monitoring & Skid warning lights on.. When plugged in at my local friendly garage I see these fault codes, do I need further investigation or should I go ahead and change rear left speed sensor? Thanks for any help

Thanks WelshGas,

ABS sensor replacement, Rear Left as indicated.

I will post the whole saga because it may help someone in the future T6: Ocean 65 plate 80k. I've just driven 2440 mile around France with ABS Tire pressure monitoring & skid warning lights on.... Because I have the "All in warranty" I put it in main dealer who 1st saw the fault codes I've posted BUT they needed more info for a Claim... After investigating they reported a wire issue not covered under warranty . They charge me £300 for further checks and replaced a wire,... Pick up van yesterday drove 37 miles no lights or alarm came on... Fixed???? Today 24 hrs after picking van up started van on drive and all same lights appeared!! Drove 1km to local garage lights went out, plug into their computer fault points to rear left speed sensor as my photo ... Very frustrating... Sent all information to main dealer who I will visit Tuesday!!!!?

Very frustrating. They will probably try to say “ Oh, there were 2 problems then “.
I have seen mentioned elsewhere of corrosion to ABS wiring in the L rear wiring harness affecting the ABS sensor. ABS sensors can be intermittent at first before failing.

Hopefully on Tuesday they agree to change the left rear speed sensor based on the fault code stored in computer

I have the same problem (lights that is, not a dealer who mis diagnosed) and have to do my repairs in the street outside my house - it is therefore really useful to minimise having to live the van part way through.

Is the harness on the rear left that corrodes accessible or hidden between the liner and the wing?

Also, are any of the four sensors more frequently the one to go faulty?

Finally, I was confused by part numbers. Are they handed left and right but same front and rear? Looking at Bosch on Euro and they only list front left and front right.

Had just this problem last year on my 2011 t5.1 SE. Took it to Retro Resus in Taunton ( who had fitted a new engine for me a few weeks earlier) they immediately identified ABS sensor failure - fitted a new one - all done - no drama and reasonable price. They are an amazing VW/Audi specialist who do engine tuning and new transporter engines. They are very knowledgable and I can really recommend them highly. Having been ripped off by VW dealers for several years they were a breath of fresh air and very professional.
Despite me living in York they are now doing servicing for me as we come down that way fairly often. After its new engine and Dsg remapping the van is transformed.
