Hi, just joined after purchasing a 2006 A4 1.8T Quattro Convertible.
It's done 110,000 miles so was just wondering whether the gearbox and diff oil should have been changed by now (it seems to have mostly a main dealer service), or when they should be changed ?
Cheers
Simon

Hi and welcome.
You will find all you ever need to know on this forum and specifics in this B7 section.

As with many things B7, unless you have any proof its been done and when then assume it needs doing.
B7's of all variant forms will benefit from Gearbox and diff oil services, so unless you have data to says is been done recently and at that milage, get it done.

Enjoy the car.

Thanks for the welcome

Yes, was planning to do it anyway, just wondered if it should have been done already in one of the services ?

Anything to watch out for on these quattros ?
Got the abs/traction control light come on and off a couple of times so I'm assuming a sensor or maybe wheel bearing ?
Had the same on a Mondeo and the wheel bearing had a magnetic strip built into it so when it started to move threw the warning lights up.
 
If this is your first Audi then I doubt you will have VCDS, always worth getting a scan to see what is going on at grass root level with the car, sometimes it's just a random fault that you can clear, if not it will enlighten you further to a fix.
Like all Audis and B7's , one allways has to be on alert whether its Quattro or 2wd , it's not the car as such but the age they are now.

A stamped up service book alone is not proof the car has been looked after, even if it's a spanking clean car.
At 100k and over miles there should be a good amount of receipts for work carried out on top of the basic service stamps, receipts are the history of the car and should follow it, anyone one can get the service book stamped.
my old bus has done 96k miles and has a mountain of paperwork, sometimes it is all about the paperwork with a car.:icon thumright:

Just bought a VAG specific reader so will see what it comes up with.

When you say 'whether it's 'Quattro or 2WD' do you mean that with age the 4WD may just become 2WD ? Does it just stop working but continue happily in 2WD ?
Nothing breaks/seizes/falls off - it just carries on regardless ?
Wasn't actually bothered about a Quattro version so not the end of the world if it is now 2WD, just found the car and it was a nice spec/colour,etc.
 
Yes got a load of receipts too that go with the service book. Got a matching set of continentals and it was the only A4 conv I found where the cambelt wasn't 2/3 years overdue !!

Just the nature of Quattro's and the extra running gear will mean they will have other areas that can become problematic over time and milage , that said both flavours and variants of B7 tend to share the same inherent issues accross many areas of the cars, cabs included, roof opening /closing probs is one to be aware of.
Electrics, suspension, engines...you need to be prepared for something to go pear-shaped, because it will, but they are a great car an worth a bit of hassle at the end of the day, thats life with an older car.

On the plus side, the Quattros are the better variant, some may disagree though.:whistle2:

All B7's Quattros are permanent 4wd drive , if either end stops working you will know about it, and you cant switch it off.

And whatever you do, avoid the temptation to start doing OEM mods, it's a very slippery and expensive slope as many will agree.:whistle2:

Well I cleared the codes and started again. Came up with no current faults but still have the TC and ABS light on the dash.
I got the OBDeleven device after a recommendation when I had my TT.

OBD is ok and many rave about it, but VCDS works so much better and is trusted by most users to be the most accurate and reliable diags.
If you have those error lamps on then there will be an issue with a code, its unlikely to just be an illuminated lamp.

what code did you have last time around?
 
Your ABS/TC could be down to several issues, an initial error code will always be a preferred starting point otherwise you could be just taking random stabs at it without success.
Could be a sensor or a cable fault or both, could be another electrical issue throwing an error, B7's are good at that, with small random electrical faults causing havoc in the system.

Oh no, not another code reader I've got to buy
I started with a TorquePro on my TT but knew it was a bit cheap, then upgraded to the OBD.

I'll check the history of the previous scan, still trying to work out how to read it all
 
OBD will still give you a code to work from , any ideas on what it was etc, VCDS is just much better and for coding in options etc, but personal preference really .
Whatever works the best for you.

Obligatory petrol station forecourt shot after filling up for the journey home.
Took me a walk, two late night trains, an overnight Megabus coach and a lift into the countryside to view it, I wasn't going to leave empty handed as I couldn't face the Megabus return journey .
Fortunately I think it's turned out well.

Ok looked at the previous scan before I cleared, quite a few but probably years worth I guess, I think a load have been triggered by a battery disconnect and a jump start - the only ones I see relevant are -

00290 - Static - Left rear wheel speed ABS sensor
01826 - Intermittent - Steering Angle Sensor
 

00290 - ABS Wheel Speed Sensor Rear Left (G46): Signal Outside Specifications​

00290 - ABS Wheel Speed Sensor Rear Left (G46): Electrical Fault in Circuit​

Possible Causes​

  • Open Circuit in Wiring from/to ABS Wheel Speed Sensor Rear Left (G46)
  • ABS Wheel Speed Sensor Rear Left (G46) faulty

Possible Solutions​

  • Check Wiring from/to ABS Wheel Speed Sensor Rear Left (G46)
  • Check ABS Wheel Speed Sensor Rear Left (G46)



Possible Symptoms​

  • Malfunction Indicator Light (MIL) active

Possible Causes​

  • Temporary Supply Voltage Interruption
  • Steering Angle Sensor (G85) faulty
  • Steering Column Control Module (J527) faulty

Possible Solutions​

  • Perform Steering Angle Sensor (G85) Adaptation
  • Check/Replace Steering Angle Sensor (G85)
  • Check/Replace Steering Column Control Module (J527)

Special Notes​

  • When found in Audi A4/S4/RS4/Cabriolet (8E/8H): Brake Electronics, these are the most likely causes if the Basic Setting fails or the Fault comes back shortly after clearing. See TPI 0984403 for further details.
    • MY 2001: Steering Column Control Module (J527) was the most common fault
    • MY 2002: Steering Angle Sensor (G85) was the most common fault
    • MY 2003/2004: Experience has shown the Steering Angle Sensor (G85) were the only cause, Steering Column Control Module (J527) were not defective yet.
    • MY 2006/2007: Steering Column Control Module (J527) was the most common fault

I guess the first thing to do is whip the wheel off and see if theres anything obvious on the left rear ?
 
yep, the abs sensor cable is normally the first thing to go, work back from there. :thumbs up:

If you disconnected the battery or had a supply problem the steering wheel angle sensor will reset itself after a straight line and a few full rotations of the steering wheel or you can just do it manually.

Previous owner changed the battery and then went flat so got jumped or removed to be charged so could have been that. I've cleared the codes now so I'll see if that one comes back :thumbs up:

Well it did come back !!

Any recommendations of where to buy a speed sensor from ?
Genuine or aftermarket OK ?
