Do you have a part number and price on the resistors please Berni.


Don't have a part # but will on Thursday. However they are known as 'Series Resistor' for the oil cooler fan assemby @£33.10 ea. Identical part for the A/C.

Hi

Oil cooler fan resistor, 993 616 521 01 and I paid £32.

I tried to get the low speed to come on while driving around this evening, but the needle would not go past 9'clock and whenever I stopped to listen it was not on. The slow speed is a lot quieter than the high speed so I might not have noticed it cutting in over the din of the engine . Doing the shorting out test shows my low speed now works just fine.

Berni could you possibly try this test and confirm the low speed now comes on?

For relay R04 - Oil: Connect 3 (30) to 7 (87c) and slow fan speed should operate. 3 (30) to 5 (87) and Fast fan speed will operate.

I'd be keen to know this test is conclusive before paying out for the parts and going to the hassle of replacing them.

Thanks

Hi Dom

Yes I did do that test both before and after, and before nothing on the slow speed test, high speed fine, and then after plugging in the new resistor both work when shorting the relevant contacts. I do much prefer the low speed because it is fairly discreet. I like hearing the engine, but madly wooshing electric fans are not my thing.

Oh bum that confirms mine are dead then Sad

These cars seem to always have a little job waiting to be jobbed to keep them healthy.

Oh well it's a good job I love the damn thing isn't it. I just bought some new head light lenses for a very reasonable price too so will be popping them on soon to complement the new fogs I've already fitted Cool

I don't believe it Surprised the garage queen's are dead too! Low speed that is - high speed are fine.

So that's:
spoiler-wall
DME relay
spoiler bearing
rear PU supports on the RHS
front PU rubbers have hardened/shrunk

...and now both resistors failed.

I'm taking it back to Stuttgart Evil or Very Mad

Mine are on order now and I'm not looking forward to replacing them nooo

Problem is with my OCD I would like the new ones fitted in the factory positions. Seems however this will be a complete ball ache without removing the PU, which I really don't want to have to do if I don't really need to.

Hi Dom

Don't worry. Once you work out where the original is your brain will make the right decision and you will mount it elsewhere. If you mount it without drilling holes then you can move it a later date when you have the PU off.

Domm, I haven't bothered doing the A/C resistor as I fear it's the least of my conditioning problems Grin
However I've done the oil one, and it's not that bad to get to.
Wheel off
Wheel arch liner off
Oil cooler loosened and lifted off it's rubber 'spuds'
(no need to disconnect as the hose is flexible)
Then there's just enough room to get in there and take the resistor off, the easiest bit was getting the new one on!

Hi Ballcock

I took one look at all the rusted nuts etc on my cooler and thought no way am I touching any of those if I can possibly avoid it. If the general area had looked a bit better I might have started to undo things. part of the price of owning a high miler I guess! I am pleased to hear it can be done though!

Ah I see!
Rusty bolts give me a dose of the dry gawks too Grin

Funnily enough , I couldn't believe how fresh and new looking the whole cooler area was when I took the surrounding bits off ..

Well - whatever these things are, they are out now and even new ones are not going back on the car.... they are made of meringue and pastry.

Did you notice where they were made? Grin

Hi

Hey! you got it out, well done. Or is that the A/C one? That one looks in really good condition. Mine was falling apart.

Are you going to have a custom one made up?

Oil cooler side. Fairly easy with the front PU off. Even though it is in one piece, the underneath is corroded = failure.

Aircon side is also out-ish - that one was cracked with one wire hanging out. I'm leaving that in-situ and going for the home-made solution, mounted as Mday has mounted his. Thumb

One down and one to go Thumb

Picked them up today and listening to the comments I decided to tackle the oil cooler on first believing this was the easiest - BIG mistake PC

Now if you have tiptronic pay attention. In addition to the oil cooler you also have a transmission oil cooler sandwiched together on the inner side of the oil cooler.

This makes it impossible to access the resistor unless you go through the front - ie take the PU off! PC It took me 10 minutes to actually find it and even with my head right into the arch you can only see the plug connector sitting on top of the transmission cooler. The oil pipes to the tranny cooler are not flexible so you cant undo the units and slide backwards. PC

My remedy was to force the plug out of the retaining clip (with a long knitting needle - fingers no chance) pull back the wire so as I could just pull the connector apart.

I then resited the new resistor on a metal flange on the outside where the fan blades will blow air onto it. The old one I have left insitu.

Taken a few pics so will post them up soonest.

Hi Zingari

Sounds like you had the same experience as me. Thank the lord that the connector pulls out.

Well done though. My temp gauge is much steadier now that the low speed works.

Picked mine up yesterday too and plan to attack it this weekend.

I was quite surprised by how large the resistors are, as from the pics I had imagined them being a lot smaller.

Hopefully as mine is a manual I may have more success removing the old ones.
