Left engine mount Edit
- Set parking brake. I raised my van and placed on jackstands for some other work, but this shouldn't be necessary.
- Support the engine with jack and a piece of 2X4. I did this under the oil pan. You aren’t lifting the van with the jack… so the pan won't be damaged.
- Remove plastic trim piece to left of battery (image 1).
- Use Philips screwdriver to remove radiator hose from bracket. Maybe you don’t even need to do this, but I did.
- Remove bracket from firewall holding radiator hose with 10mm socket… otherwise it gets in the way when you try and remove the motor mount (image 2).
- I loosened the large, center bolt first (5/8 fit better than 16mm socket) and then the two smaller ones (13mm). I carefully removed the smaller ones then slowly removed the larger one. The engine moved very little or not at all when bolt is removed. The jack held everything in place nicely (image 3).
- The mount was removed by just shifting/sliding it to the left. I thought I'd have to lower the engine a bit to remove pressure from the mount, but it just slid right out. I then shifted in the new mount and rebolted. I lightly tapped the mount through the larger hole with the driver extension (use anything) to center it before final tightening.

Right engine mount EditThere's a video of a worn right engine mount here.
- Set the parking brake.
- Remove the cabin air intake and filter.
- Support the engine with a jack and enough pieces of wood to distribute the weight.
- The two nuts on top of the mount and one bolt on the bottom are 16mm.
- Remove the old mount.
- The bottom of the mount has a ridge on it that needs to be resting in a matching channel. While screwing in the bottom bolt, the whole mount will twist causing the ridge and the channel to misalign. Screw in the bottom bolt until the ridge is about to meet the channel. Then, put a socket over each of the loose top nuts and tap them until the ridge and channel align. Tighten the top nuts to hold that alignment and then continue screwing in the bottom bolt to seat the ridge into the channel.
Left engine/transmission mount Edit
The power plant is designed such that the transmission is attached to the left of the engine, so this mount is technically a transmission mount. The Bentley manual refers to this as the 'Modified Transmission Mount'.
- Set the parking brake.
- Remove the top of the battery box.
- Remove the side of the battery box. It just slides straight up.
- Disconnect the battery.
- Disconnect ground and positive cables shown in photo.
- Disconnect the positive cable from the starter solenoid.
- To gain room to swing an extra large wrench, it may be necessary to remove the cable retainer show in the photos from the front end of the frame rail.
- A small wire harness clip presses into the side of the mount bracket, on the engine side. If you have small hands and arms you can pull out this clip before removing the mount and reinstall it after installing the new mount. See photos.
- A flat spot on the bottom front of the transmission can be used for jacking See photo.
- Support the transmission with the jack.
- The two top nuts and two side bolts are all 16mm.
- When the nuts and bolts have been removed from the mount and its bracket, the whole assembly can be rotated forward and then dropped out of the engine compartment.
Pendulum Mount Edit
A large rubber damper sits within a bushing in the aft end of the so-called Pendulum Mount that stops the bottom of the power plant from swinging forward and aft as it hangs from the left and right mounts at the top of the power plant.
The bolt on the transmission requires a 10 mm hex key. The bolt on the frame requires a 21 mm socket. Torque specs can be found on panel J 37-37 of the Bentley manual.
Instead of replacing the Pendulum Mount arm and all, another approach would be to acquire just the bushing part, which is VW part number 701 399 207b or Febi Bilstein 37099 and finding a machine shop that can insert the new bushing. The 'whole arm' part shown here is a VAICO V10-0881 which was obtained retail from Europarts-SD. If you want the bushing only, it appears these are available from Ebay sellers based overseas. It is unknown whether the VW part (bushing only) can be ordered from a US dealer's parts department.
How to extract the old bushing and install a new one with the transmission still in the vehicle is <to be determined>.
