Hi

Can you provide a bit more backround information / reasons for the work carried out? (fault codes)

Did you replace the compressor with the same make, or a different one? eg Hitachi / AMK
Did you change all four height sensors, or just the front? Did you change the compressor relay ?
The more detail you can provide the more accurate and tailored the response is likely to be!

I had been getting intermittent suspension faults such as slow to rise normal height only and had bought a hitatchi replacement awhile back in view of replacing.. Then i had faulty nsf height sensor so decided then to do the whole lot in one go.. I did have white dust in in valve block at resevoir and front but bothhave been cleaned.. Now i have the torpedo look with back extended and front on bump stop....(I also changed relax)

Try fitting new seals in the valve blocks.
Then re-calibrate the suspension..
And double check for air leaks...

That should sort it Thumbs Up 1 TR6 Rusting away quietly
