Adas recalibration ?? help!

[rufusgti]

Hi all.

I have had a very expensive month with my 2017 Leon 1.8TSi estate.

The car failed MOT on tyres and brakes so I've renewed the lot. I took the car in today for 4 wheel alignment as the rear tyres wore on the inside edge meaning I had to change the rears prematurely.

While my car was on the ramp they came in to ask if I really wanted the rear adjusting, because the ADAS cameras on the back axle will need adjusting. They said this will cost £250 and need doing at another place round the corner, or Seat main dealer. I had to get it adjusted as I don't want the new continentals wearing prematurely.

I drove home, so far no lights on the dash. At what point would you expect these to come on? I don't even know what they do, so I have no idea what triggers them. I'm doing a long journey on the weekend, is this something that will trigger at a certain speed or have I dodged a bullet/had poor advice..

Thanks for any info

Although if it is just a simple wheel alignment....not sure why a full ADAS calibration would be needed. And never heard of cameras on the axles before, unless that's something slightly different he refers to

But the kit to do ADAS, is bloody expensive

Realities are often divorced from the service manual here:-

Most cars with any kind of radar / camera based ACC, collision mitigation etc. will include re-calibration (in the manufacturer service steps) after any kind of suspension work, tyre / wheel size changes, alignments and so on.

The reality, however, is that setting a car back into alignment does nothing to impair their operation.

Carry on as normal and if you observe a change in the behavior of anything sensor based, then consider calibrating.

I've changed tyres, wheels, changed alignments, dropped subframes etc - None has lead directly to needing an ADAS Recalibration.

Thanks for your replies. Seems the garage was maybe giving me the worst case scenario, so there'd be no complaints. Who knows, but no lights on dash as yet. I'm yet to go in the motorway but I think I'm going to be ok.

MY Citroen C5 had reversing warning devices in the bumper. I think they were Ultrasonic rather than radar, but a new one just plugged into the bumper and the wiring loom. If the WSM suggested alignment, I don't have one and did it myself. But it needed a 'real' Citroen device - an identical one at a tenth the price off ebay didn't do!
