I am likely going to try the repair kit that includes the air drier from ECS. Anyone have experience with it?

It's likely you may have leaks in the air system other than the compressor. Check that the 4 air suspensions are free from leakages before trying the kit again. I have a similar issue too on my V6 Treg.

I installed the repair kit 100698010A yesterday and found that the old piston seal was worn. There was black residue from the wear and tear all inside the compressor head. When I took apart the old head/drier I found the desiccant beads to be brown and brittle. I did not open up the new one to see what they are supposed to look like, but I think they were the originals and were no longer removing moisture from the system as evidenced by the rusty spring inside the unit.

Perhaps moisture in the system caused premature wear on the piston seal. No errors on the first ride. I will report again to inform how the repair holds over time.

The desiccant beads discovery makes me think replacing the piston seal and the desiccant beads would be a sufficient repair for someone not willing to buy the whole kit.

How about an updated report? How has the repair held up? Where can I purchase the desiccant replacement?

I just used one of the kits to replace the piston ring, works much better now... no errors so far.
I hope I'll not have to do the dryer too.

I did a rebuild kit and it only lasted a couple of weeks. Picked up a new compressor from Arnott on Ebay for much less than dealer. has been flawless for 18 mos.

On the older models (T1, T2?), the drier is supposed to not ever need service. According to an SSP, the incoming air is dried and moisture is absorbed. When it is discharged, it goes through the drier again and the outgoing air is moisturized, thus rejuvenating (drying) the desiccant.

Thanks for the info.
Anyway I'll keep an eye on that ring... probably they (ebay sellers) all buy it from the same supplier in China.

Anyone have an experience with a repair kit that lasted longer then a few weeks?

I got one on eBay (or Amazon, I can't remember) for less than $40 USD shipped. Seems to be fine. <shrug>
