My driver's seat rocks forward and back with acceleration. I bought this kit from ECS tuning, but it's for manual seats only, I think:

Audi B5 A4 Quattro 1.8T > Interior > Seat > ES#4769 ECS Front Seat Guide - Slide Kit - Priced Each - One Per Seat - B5SGKIT

How do I fix the driver's seat. Is there a clip or plastic piece that breaks?

 

Seems like it's the same part for power and manual seats, there's a thread on some C5 A6 forums talking about these and those have power seats. Also it's listed for V6s, which have at least a power driver's seat.

 

Hmm that would be good.

There is a center rail on the manual seat, and just glancing underneath I can immediately see where one of the three parts goes.

However, on the power seat, searching around underneath with a flashlight, I can't see a center rail or any place where the parts would go.

Also, the Bentley manual says you need an airbag tool when working on the power seat, which I don't have.

 

Sir.

The two mounting points at the front of the seat in the floor could be the issue. Check them.

 

Thanks I'll pull the covers off and take a look.
