Radar Blocked, ABS/ESC, City Safe, Collision Warning faults

Did you check the wiring loom before air filter?

I am having the same issue with my 2013 s60 t5 awd. So many error codes. Did you fix the issue? I'd appreciate an update since I am running out of options to fix this.

Someone mentioned, abs senor and wheel speed sensor. Did you get a light on dashboard since abs sensor was bad?

[iroll91]

Did you get a message on dash with "abs" light on? Since the sensor was damaged?

Has anyone used VIDA on the car to see what faults are logged in the ECUs?

My issues were finally sorted last week.

The auto electrician wasn’t getting back to me and nor was my local Volvo specialist, so I had to resort to using Volvo. £2,000 later (£1,300 for this problem and £700 to fix my air conditioning). Everything is working!

The Volvo specialist I use tried programming the unit but it failed and and I lost the lane departure warnings and the reading of the road signs.

The main dealer replaced the unit behind the rear view mirror, at some point the windscreen had been replaced and they think that probably caused the issue.

I’d previously had one of the wheel speed sensors replaced and that fixed the hill decent problem, along with the ABS warning.

To think my Volvo was bought to replace a Discovery 4 that was expensive to run, but in the 9-10 months I’ve owned my XC70, it’s cost over £3,500 in repairs, even my Land Rover never managed that!!

wow, thats an expensive fix.

you had abs warning on Dash?

I have all the codes you mentioned in the thread but not much on dash except "collision system service"

[iroll91]

Yes I use VIDA.

I have these codes:

software incompatibility is just from the tune.
reverse camera and tpms, I dont care about since they have been there before.
Ignore the rear differential one as I had the awd DEM module unplugged at the time.

Would appreciate any help from the group.

[Fitzy73]

That’s a big list, although mine isn’t much better!

I did have the abs warning, but the wheel sensor sorted that, but it didn’t help the other problems.

Hi I have the exact same issue with my 2016 D5 SE LUX, it seems from all my research and codes from my icarsoft unit that it is the rear left ABS sensor, although I can find lots of after market sensors, I cannot find anywhere I can source a genuine Volvo sensor. I would be grateful if anyone has managed to source a genuine part. This looks like a relatively easy job on you tube, I'm going to remove and clean the sensor today to see if that helps.

Thanks in advance.
