Is there a DIY for the replacement of the front valve block? I am planning on doing mine and any help would be appreciated.
If anyone can even walk me through the process I can take some pictures and post it as a DIY on this forum,

I posted this a while ago. It should help you.

 

Very do-able job. I changed mine last weekend, while referring to cmb6s's post. I really took my time and it was about 1.5hrs total. cmb6s's post pictures and procedures were great. These are a couple of my takeaways:
- To depressurize, I dropped the car to access mode and shut it off. Then I slowly unscrewed the lines (12mm) at the valve block, letting them leak down. This allowed a safe, easy depressurization without using the IID or another tool.
- I did not have to remove the whole inner fender liner. I removed the front right wheel and the screws/clips out of the front of the plastic inner liner. I pulled that back and secured it with a bungee cord around the steering knuckle. That gave me enough space to do the whole job and it was never in the way.
- With a 12mm wrench, remove the brass connectors (Voss) of the plastic air lines. The new valve block comes with new Voss connectors. Don't be lazy; swap the old ones for the new. It's easy to do and reduces risk of a leaking connector. DO NOT CROSS-THREAD THE CONNECTORS. You're screwing brass into plastic so it's easy to do bad things. My final connector wanted to cross thread so I yelled bad words at it and it eventually shaped up and sealed tight.
- After I started the car and it worked, I sprayed soap/water around the connectors to ensure there were no leaks. It hasn't dropped at all in the last week.
- Wish I had done the job months ago instead of letting it drop each night and putting the additional strain on the old compressor.

 

Thanks for the inputs. I'll be tackling this over the coming weekend.
