Audi 80 2.8-Q to 1.9TDI-Q

[mario2005]

It's easyer if you give the gearbox code or at least tell the engine of the A4.

Engine code is AFN

Engine code is AFN

AFN = 1.9TDi 81kW
Gearbox code DGW, type 01A. Final drive 35:9 = 3.889.

1. Gear = 3,500
2. Gear = 1.944
3. Gear = 1.226
4. Gear = 0.838
5. Gear = 0.659

65mph is at 2241rpm when using 225/45 R17 tyres.

Should be perfect

Cheers

The gearbox should fit to the engine, AFAIK the bellhousing on the gearbox has a boltpattern for I4/I5/V6. ETKA lists the clutch diameter as 240mm for V6 and 228mm for TDI, so the clutch and flywheel from A4 should be ok.

Rear ratio is the same for V6 and TDI: 35 : 9 = 3.889, also driveshaft flange is 100mm on both. I'm not sure about propshaft but they are both 01A gearboxes, so i'm hoping that the 80 propshaft should bolt on to A4 gearbox. I'd rather keep the 80 rear diff as it has manual diff lock in it.

Get the engine out from donor car 2h work and done nice and smooth



Then started easy thing Wiring All out front panel heater etc

And after some hours of its done

In this moment looks like its will be not so hard to change original wiring from 2.8 to this one only thing whats worry me is immobilizer but we will see
Next thing what i found out taking wires out was small issue about accelerator pedal need to use one from diesel and take all pedal housing out Because diesel have electric accelerator pedal but 2.8 manual.
Every second i spend on the car i understand more and more that idea to buy whole car was the best because so many bits and pieces are not the same.

Next on the plan is
1)
Sort out engine mounts original 2.8 no good original 1.9 nearly impossible to take off
2)Gearbox
3)taking apart 2.8

If somebody have some advice or think i am doing something wrong

[mario2005]

Get the gearbox yesterday
But like usual nothing is perfect
I get it defected with middle differential problem but its ok because i have my original petrol gearbox i was thinking just to swap them etc
But when i opened i i found out bad surprise


Can somebody help me with advice how to get that bearing off the shaft and where to get new one ????


And second thing can somebody tell me whats missing in this picture ??


How many number 1 rings need to be inside ??
And whats the number 2 in picture ??

Hi,
Not sure if this is any use to you, I *should* have a spare 5 speed gearbox from a 80q 2.6 V6.
Pretty certain we met at Eric's (Warrington, on the same road quite near to you) when you and 'Spions' looked at the parts from the green S6 I'm breaking, I remember then you mentioned about the TDi conversion you were working on.
I'm back at Eric's from Tuesday onwards for about a week.

[mario2005]

Yes that's me
I have the same gearbox left from mine 2.8 quattro just in this moment i am looking for the best way to save both of them
But i will definitely com to see how is yours building

Still looking for part number or ideas abut bearing

[vag_nutter]

Hows this going? Have been thinking about doing the same with my 2.6 avant quattro

[Mark.se]

Like wise, how's it going? Cheers for popping along to Eric's for a chat when I was over.
Got the 80q back home now, had a few teething problems, as good as sorted now
