Default Rear Blower Motor

Anyone know if this and this are the same motor?

Edit: Yes they are!

The part number (0 130 111 145) on the Vertex site is the Bosch Part Number and when I put that number into the getcoolparts site up came BSH054573. I'd call them and ask?

Get Cool Parts states that their part is the same Bosch part.

I've placed an order and will let you know how it turns out.

Cheers,
Dave

The Get Cool Parts Bosch motor has just arrived.

The box is marked:
Bosch
1 St/Pc
Motor Ventilador DPD
0 130 111 145
The motor, itself, is stamped:

29090Z
DPD 12
0130111145
3.32.1
I haven't pulled the old motor yet, but it looks like Get Cool Parts is providing a bargain.

I'll post again when I've had a chance to work on the installation.

Cheers,
Dave

Default New Motor Installed

I've replaced the rear fan blower motor with the new part I've received from Get Cool Parts.

My camera battery died as I was taking pictures of the process on reassembly, but I managed to get the pertinent pics. The fully assembled fan blower housing is not that interesting. I removed if from the car in about 3 minutes flat and took just a few more minutes to replace it. I've done this a few times before.
edit: there is a pic in post #19 below that shows the mount points and connections.

I left the "down tube" in the car and removed the tube that attaches to the top of engine by removing 3 phillips head screws.

I then seperated the blower housing halves by removing the torx screws around perimeter of the housing.

The wiring cover and wires were then removed:




Then the two 7mm bolts holding motor into housing half were removed and the motor and fan assembly pulled from the housing half by gently prying the motor from housing. It's a press fit. I used a wide blad flat screw driver, inserting it between the plastic housing and the top of the motor above where the wiring came out. You can see the scoring on two of the four vanes within the housing below.


Here are the two housing halves and the blower motor assembled to fan in lower right.


Push the motor from fan with a drift punch. I cut a hole in a board in order to support the full circumference of the fan housing and allow the motor to drop through the board. I then hit the motor shaft rather hard to get it out. Not a comfortable feeling as I was afraid I might break the fan. With increasingly weighted blows it began to drift free.


New and Old motors. The hole I cut was just barely snug enough to hold the motor from falling to the floor.


To reassemble the new motor to the fan I flipped the fan over on my gig and gently tapped the motor in. The fan wobbled ever so slightly when spun after being fully seated, but I don't see how I could have done any better. It spins fine in the car.


A couple of pics of the new motor markings and the box label




Many thanks to those on Rennlist that posted the instructions for doing this update and for making the part number of the Bosch motor available.

Cheers,
Dave

That's great that it works Dave. Hopefully the parts will still be cheap if I need to do this myself.

Dave, what were your symptoms for diagnosing this? Had the fan stopped entirely? I ask because mine is now making a noise, though it might be the fan assembly hitting the plastic. The motor is vibrating badly, though, hence my question.

Regards,
Clay

Shrieking and whining. Then an out of balance along with vibrating and associated noise. A couple of weeks ago it go so bad that I had to pull over and check it. I gave the housing a good, firm wrap while it was running and it settled down enough for me to leave it running. It's pretty damn cold here right now and I wanted the heat!

After removing the old motor I can clearly see that that bearing at one end is shot. There is a cir clip on the shaft, but I haven't tried to remove the bearing. I had read in another post that the bearing replacement didn't look doable without some effort so I just bought a replacement.

Cheers

Dave, what does the 3 minutes involve to remove it? I want to remove it soon so that I can pull apart the inlet manifold on that side to clean it up, look for top of engine leaks and re-seat the manifold.

edit: there is a pic in post #19 below that shows the mount points and connections.

There are two 10mm bolts that hold the full blower unit to the engine. Both are accessed from the left hand side. One near the top. The other down the left side. You can get one hand in there with a 1/4" socket and remove it blind. After six or eight times it'll become second nature.

The jubilee clips (hose clamps) on the down tube get loosened with a 7mm socket.

The engine shroud connection comes free with a bit of tugging.

There is an electrical connection on the left hand side. Pinch the tabs and pull.

If you remove the down tube, there are two air hoses, a temperature probe and resistor that must be disconnected. I immediately stuff the open holes (down tube and engine shroud) with a good sized rag. I don't want to try and fish anything out of those places!

Getting it back in is a bit fiddly. I generally assemble the blower and tubes and wriggle it in to place with the down tube (connecting the blower and down tube as I get everything into place) and then fit the engine shroud connection. I then reinstall the two 10mm bolts by pushing and tugging a bit on the blower assembly to get them lined up. I then hook up the connections and tighten the jubilee clips.

I am going to do this as well as a winter project. Mine is making the chainsaw noise. Did you use discount code "AUDI" for coolparts site?

Nope. Didn't know about any discount codes. Was it right in front of my face?!

Google is your friend. 5% off and I am not sure if it did it or if shipping was already free, but it was for me.
