Parts for your 2019 Audi Q5-Rack boots

2019 Audi Q5 rack boots — what they do and how to look after them

Rack boots are absolutely relevant on the 2019 Audi Q5 (Type FY/80A). Audi’s factory repair information (erWin/ELSA) for the FY/80A platform details an electromechanical rack-and-pinion steering gear fitted with protective bellows on both ends, and the Audi ETKA parts catalogue (Group 48 — Steering) lists these bellows/gaiters as service parts. In plain terms: yes, the 2019 Q5 uses rack boots.

On this model’s electric power steering, the rack boots (also called bellows or gaiters) seal the inner tie rods and the ends of the rack, keeping dust, water and road grit out while holding in lubrication. They stop contaminants chewing out the rack bar, pinion and inner joints — parts that get pricey very quickly if wear sets in.

While there’s no hydraulic power-steering fluid on the 2019 Q5, a torn boot can still let water and dirt in, leading to corrosion, stiff steering, or inner tie rod play. Left too long, that can translate to odd tyre wear, vague steering, and potential WOF/RWC issues in NZ/AU. Boots also help keep the rack grease where it belongs, so any split can show up as grease flung around the wheel arch.

As part of routine servicing, a quick visual check goes a long way. With the front wheels turned, look for cracks, splits, missing clamps, or any signs of grease or moisture inside the bellows. If there’s damage, replace the boot promptly — it’s a far cheaper fix than a steering rack.

• Inspect every service or at least every 20,000 km, and after off‑road or flood exposure.
• If a boot is torn, replace the clamps as well (often single‑use), and clean out any contamination from the inner tie rod area.
• Have the toe checked and adjusted after any tie rod or boot work — even small disturbances can shift alignment.
• Avoid pressure‑washing directly at the bellows or twisting them when the vehicle’s on a hoist.

Replacement is straightforward for a trained tech: remove the outer tie rod end, slide off the old boot, clean and inspect the inner joint and rack end, then fit a new bellows with the correct clamps and refit the tie rod to spec. If there’s any play or corrosion, it’s smart to address the inner tie rod at the same time. Catching a failing boot early keeps the Q5’s steering tight and quiet, and saves a bundle down the track.

Popular questions about 2019 Audi Q5 rack boots

Does the 2019 Q5 definitely have rack boots?
Yes. Audi’s erWin/ELSA repair information for the FY/80A Q5 shows bellows on both sides of the electromechanical steering rack, and ETKA lists them as serviceable parts. They’re essential to protect the inner tie rods and rack from contamination.

How often should rack boots be replaced?
There’s no fixed interval. They’re replaced on condition — if cracked, torn, weeping grease, or with loose/missing clamps. Have them inspected at every service or at least every 20,000 km, and sooner after off‑road or flood exposure.

Will a torn rack boot fail a WOF/RWC?
Often, yes. In both NZ and Australia, steering integrity is a safety item. A split or dislodged boot that risks contamination or allows play in the steering can lead to a failed inspection until repaired and re‑checked.
