Servotronic Fuse

[sdjeff]

I am curious of who else has pulled the fuse? I did about 6 months ago and will never go back. The steering was very numb stock and once i pulled it i got a lot of feeling back in the wheel. I can be more precise on turns and less over/under correcting i feel that happened with the stock steering because of how lose it is. I know some people didn't like the feeling in parking lots but after a few weeks i was completely used to it.

If anyone doesn't know what it is, its a fuse for the steering booster (not the power steering) that is located under the driver side dash with "servotronic" written on it.

is it easy to put back if you pull it? or is it something you tape over?

Just plug it back in. Its about an inch^3 little black box/fuse.

[ataylor]

will probably try it today

[Blarg]

I really like the stock steering but probably because the car handles so well. I may have to try this.

i can't see it... can you take a pic or somethin?

[sdjeff]

I'm an idiot.. its in the fuse box. Its been forever since i unplugged it.

[sdjeff]

better pictures..

Will have to try this out, thanks. Throw any codes?

[A4CE1]

i pulled it on my previous 02 allroad. the steering in that thing was waaayyyyy over assisted. it was a whole new car without it. and i never saw any codes.

[sdjeff]

No codes for me either. It really does turn it into a new car.

[eskimopunk]

cool thanks for the pics. im gonna have to try this out

[eskimopunk]

I did it and damn it makes the steering heavy lol. I'm gonna have to get used it to see if it's better

[sdjeff]

Give it a few days and you will get used to it.. i don't even notice anymore.

[RedS-line]

someone said it was better for autox with this removed. anyone think this would be true?

[praudi]

so wait u have to pull 2 fuses one in fuse box and one under steering?

[sdjeff]

No just one.. the pictures just show two different angles.

[sdjeff]

Definitely would be true. You can feel the road better and make more precise steering inputs.

I've driven Jeff's car and it is heavy at first but once you get used to it the feel is much more connected to the road.

+1

it feels like you're taking the lag out of your steering.. so it is heavier and you really tell the car where you want it to go. Surprisingly..even on non-sline suspension, it goes there

[eskimopunk]

should call it the '640 mod' lol

[ChampionV63.2]

should call it the '640 mod' lol

I did the mod today and wow I am IMPRESSED. Seems like it drives like a bmw without all the steering wheel communication of road imperfections. A little heavy in the parking lot but once your rolling its great! The crazy thing about the mod is I just put 8mm spacers on the front and 15mm on the back and had a slight shake in the wheel which I no longer feel??? I can't imagine how those two issues are realted...

[eskimopunk]

I'm used to parking with it now... i think you just have to expect it. When I first did it, I was surprised every time i turned the wheel when trying to park now i just put in a little more effort and it's all good

[sdjeff]

Glad some more people are enjoying the mod

[Grishbok]

once i get my car back from its latest reconstructive appointment I am very anxious to try the 640 mod.

[rbecker]

Been driving it without the stronic fuse for over a year... no going back.

[NorcalPB]

Tried it for like three days. I loved the feel of the steering when driving spiritedly, but considering my town consists of crazy tight and technical parking lots and straight roads, it just wasn't that practical.

[sdjeff]

^ Understandable..

Where I live its hard to find a straight road I HAVE to drive windy roads to get anywhere.

[ataylor]

My car has this code (found it at the shop when reflashing with APR):

P0042 - 002

any chance it's related to my pulling of the fuse? Never felt any issues with the car since the '640 mod' ..

[Grishbok]

No, that code is an o2 sensor heater fault.

OXYGEN SENSOR TROUBLE CODES

There are two types of Oxygen Sensor trouble codes: O2 heater circuit codes and O2 sensor codes.

O2 Heater circuit related codes include P0036, P0037, P0038, P0042, P0043, P0044, P0050, P0051, P0052, P0056, P0057, P0058, P0062, P0063, P0064 & P0141.

O2 Sensor related codes include P0130, P0131. P0132. P0133, P0134, P0135, P0136, P0137, P0138, P0139, P0140, P0142, P0143, P0144, P0145, P0146, P0147, P0150, P0151, P0152, P0153, P0154, P0155, P0156, P0157, P0158, P0159, P0160, P0161, P0162, P0163, P0164, P0165, P0166 & P0167

The heater codes will set if a fault is detected in the O2 sensor heater circuit. The O2 sensor codes will be set if the O2 sensor readings remain low (lean), or high (rich), or do not change quickly enough, or do not change at all.

The O2 sensor reads unburned oxygen in the exhaust, and generates a voltage signal that is proportional to the amount of oxygen in the exhaust. The signal can vary from a low of about 0.1 volts up to a high of about 0.9 volts. A low voltage signal indicates a lean fuel mixture. A high voltage signal indicates a rich fuel mixture. The engine computer uses the O2 sensor's input to balance the fuel mixture during closed loop operation. A bad sensor may prevent the system from going into closed loop, and usually causes the fuel mixture to run rich causing an increase in fuel consumption and emissions.

A low voltage (lean) reading may indicate a bad O2 sensor, a vacuum leak, or a condition that allows unburned oxygen to enter the exhaust. Check intake vacuum at idle, and inspect vacuum hose connections. If okay, check for a misfiring cylinder, a burned exhaust valve that is leaking compression, or a leaky exhaust manifold gasket.

O2 sensor quick checks include watching the sensor's output voltage as the fuel mixture changes. Momentarily disconnecting a vacuum hose will cause a lean response from the O2 sensor. No change in the reading or a very sluggish response would indicate a bad O2 sensor.

NOTE: If you get an oxygen sensor code plus a random misfire code and a MAP sensor code, the engine probably has a serious vacuum leak.

go on the allroad board on audiworld. they do call it that haha

640 mod is the most cost effective mod I have done so far!!!

[Grishbok]

I need something in between this. Without the servotronic, it takes to long to make the countersteer. With the servotronic, its a little too easy to overcorrect.

Slideways audi.

640 mod is the most cost effective mod I have done so far!!!

yeh it takes a couple days to get used to - then when you get into other cars they feel like toys!

***edit - added it to my sig

lol i will have to add to my sig

[Grk_A4]

Just did this mod about 2 weeks ago. It took me about a week to get used to it but now I love it. No going back!

[Koby]

I'm going to 86 my 640, lol...

[Grishbok]

i need a 320... 640 is too much, 0 is not enough.

[A4CE1]

i need a 420.... that would probably provide the best possible situation. heheh.
