Engine mounts
 

Hello community,

I finally acquired a D3, 4.2 40V BFM in September last year, but have not been driving with it very much as my daily beater ist a D2 4.2 40V...
After doing some maintainance on it (broken water pump on the oil cooler) I was asking myself why there are no connectors on the "electric" engine mounts. Thus the engine runs smooth as silk, no codes in VCDS...?? :Confused: But a cable attached to the aluminium on the mount, that ends wit a blank connector...
The same thing on the passengers side (LHD) but without any cable even close to the mount...
Picture in attachment...

Probably the solenoid in the engine mounts failed so someone replaced it with a resistor (in the bare plug) instead of replacing the mount.

What about on the passenger side? There is no cable at all :Confused:

Tucked away somewhere?

I will give it a good look as the car is without bumper and the oil cooler/filter right now...

These mounts all failed very quickly (couple of years) and there is/was an Audi TSB to replace them with terminators. What year is the car out of interest, as I'm not sure this was a dealer-fit workaround and/or production change.

The car is a 2004. It seems like it was replaced at Audi, as everything looks so original, the connector with the resistor has an Audi sticker on it :hammer: And an LED lamp inside...
But the engine runs seamles, smooth and no vibrations.
I will replace them anyway but they are so expensive :mad:
We have found the other cable too!

I had an 04 D3 and from memory these hydraulic mounts failed when the car was about 6 years old. (Failed meaning they threw an error code on diagnostics when car was scanned. As they were crazy money and could only be got new at the time, I decided against replacing at the time.
I then kept the car for several more years and never had any issue with vibration or similar. I’d leave them to be honest.

Don't get used ones as they will also be faulty. New ones are probably a waste of money as they will probably only last a couple of years. My first failed at 3.5 years and don't forget these new parts have been sat on a shelf deteriorating for 10+ years.

The FL D2's have similar mounts.
As they're hydraulic, I just thought the electrics were a sensor for when the mount failed?

I didn't think they were or are in any way "active"...
