Hi

I’ve got a mk3 2020 Octavia vrs (petrol) and the n/s/r suspension is approximately 15mm lower than the o/s I’ve checked for broken spring but all is good, could the cause be the ride height sensor I don’t have any warning lights on the dash any help would be appreciated

Welcome to the forum.

Do I assume correctly this vehicle isn't fitted with DCC suspension?

I cannot see any way the ride height sensor can actually affect ride height - it senses the ride height for correct headlight alignment - not control ride height.

Most likely a tired spring - or possibly an incorrect replacement at some time.

Thank you for your reply this car does have DCC suspension and ive owned the car for 3 years its been fine so not sure why its dipped on the n/s/r

The springs on the rear don’t have any rust on them so don’t think they’re tired

As far as I am aware, DCC only has an effect on the shocks and not the suspension height.

Thank you for the reply I took the n/s wheel off today and the green arm of the sensor didn’t seem straight and I thought a bit seized so checked the google doctor which pointed me towards the sensor so I thought I would ask for advice off the BRISKODA experts.

Zero relation between the headlight level sensor and ride height. DCC only adjusts the shocks - nothing to do with the springs or ride height.

Most likely a knackered spring, although potentially a collapsed top mount and suspension issues (LCA and strut come to mind).

I replaced both springs on my MK2 and tightened bolts. I made the mistake of tightening swing arm bolts on one wheel on the ground and the other still jacked up. When the car was lowered the one tightened jacked up was around 20mm higher. Think the bolts have to be tightened with wheels on the ground to make car sit level. Might be worth loosening and retightening.

Thank you for your reply, it’s worth a try if not I’ll get it booked in at the garage.

Do the rear springs have any colour paint marks or part numbers. Check that they are the same. They should be replaced in pairs but its not unknown for a broken spring to be replaced that doesnt quite match the other.
