Has anyone every have their front calipers seize? My mechanic friend can't get the inside front caliper pistons to retract. He said there are seized.
Any input would be appreciated.

I believe you'll need a special tool to retract them: Search SiteSearch Caliper Tool - PBK-18PCS - Brake Caliper Piston Tool Kit - 18 Pieces - ES#2153340

Isn't this tool for the rears that have the park brake.
I thought the fronts just pushed back in. This is what I thought I saw in a service manual a while back.
They should push back in freely, try opening the bleeder valve 1/2 turn with a rubber hose attached going into something like a water bottle for old brake fluid to run into.
I don't think the kit referenced is for calipers with pistons on both sides like our Touareg's.
I also read somewhere that you need to block pistons you are not retracting so they don't move out as you push another one in.

Sorry, I automatically assumed you were talking about rears.
The Treg's calipers are monoblocks, so the tools listed by VWBobNY will work but not those for single piston calipers. The mechanic is likely to need a piston extractor that looks like a 90 degree bent pliers. I am looking for one to preventatively rebuild the calipers (seals and dust boots) later.
Was the brake pad sitting straight on the round dowels? If not the pistons may tilt and lock in the bores. I clean the dowels with a wirebrush so the brake dust does not cake up and block the movement of the pads.
Also, I flush the brake fluid with each set of pads, therefore I do not worry about internal corrosion.
If the fault is in the hydraulics and the pistons can be freed by loosening the brake bleeders, then you have a bigger problem, IMO.

Unfortunately, I was forced to trade in my 2006/V6 when this happened two years ago. I live in a remote town in Alaska and could not find a mechanic to repair my caliper issue. In desperation, I traded in my VW one month after diagnosis. I see the vehicle being driven around town by the current owner so I'm guessing they found a worthy mechanic to correct the problem, I had no such luck. Find a reliable independent mechanic or dealership to deal with your car. This repair will be costly, I was quoted $4K, but if you love your car as much as I did, get it fixed instead of trading or selling it. I purchased a brand new 2013 Subaru Forester thinking I would have a "worry free" experience, it was quite the opposite. Between bad service and inflated charges for oil changes my opinion has been VD'B'd for sure! I just purchased a 2005 V8, made sure it had no engine, break/caliper issues, I've been happy ever since. These are really great cars, nothing drives like them, will be worth keeping once repaired. Good luck!

The Op said retract not extract. Special tools are nice but just a couple of G clamps or similar will do the job. Helps to open the bleed valve as mentioned by others. If the pads are still on then even 2 screw drivers between pads and disc will work but it is a bit of a rough as guts way to do it. Pistons can seize but is isn't all that common in my experience. If it has then generally the calliper is a throw away in my opinion as the bore will probably be damaged. John

Replaced Calipers and everything is perfect again. Both front were seized badly. Salt on the roads suck, would most likely been the cause.
I believe it is best to either run the rotor, pads and calipers to their end of life or replace pads and rotors often. I will be wearing them to their very end of life.
