Any suggests of what to do about these?

Clean the metering valve with distilled water. It connects to lower end of DPF. It may be clogged. Not sure about the speed sensor codes though.

Where's the metering valve located?

You'll need to access it from the under side of the car, on the passenger's side, where the down pipe meets the rest of the exhaust. There are some detailed pictures here in the forum if you look around a bit.

You're looking for part #14 in this diagram of the down pipe:

Is it DIY friendly? #15 clamps it in place? I don't have a garage and just hand tools. And not the sharpest tool in the shed, either.

I think it's DIY-friendly. You'll need to remove the covers under the car to access the valve and removing the valve is fairly straightforward as it does just clamp in place.

Okay, sounds good. If it gets ugly, 9mm you're in trouble.

I just ordered the 16 19 7 244 149 Repair Kit Filter from Tischer for $36.50. See my photos in the DEF Tank Questions thread.

I had a problem with the transfer module mounted on the top of the Active DEF tank. To access this pump, you need to drop the exhaust, remove the heat shields attached to the bottom of the passive tank, support the rear of the passive tank with a strap, then remove the nuts holding the passive tank to the plate in your trunk. Then you can pull off the plate in the trunk and work on the transfer unit.

I am reinstalling the exhaust this morning.
