Your supposed to check your tyres before every journey and check pressures on a regular basis.
How did you not notice that ?
That's shocking wear for 15k. I was going to ask if they were cheap Chinese tyres but shocked you said they were a good make.
Could they be counterfeit or very old ?

 

The only tyre with an issue is the left rear.
That has very heavy wear all across the tread, only slightly more on the inner edge.
The wear with excessive camber/toe gives ridiculous inner edge wear, as in worn to a chamfer on the inner edge. You haven't got that.

The right rear is just worn to its compound change point.

Were there any advisories on its last MOT?

Needs everything checking on the rear, especially the rear left.

 

They are too much toe in, you can see how the rubbers scrubbed to a sharp point on one edge of the grooves.
They should be a very slight toe in.
Also too much neg camber can cause the shimmy on bumps.
Check the camber arm bushes and the trailing arm bushes first, if they are ok then adjustable camber arms and wheel alignment should sort it

 

Thanks everyone! As I explained due to back issues and shitty weather I have not got down on my knees to look at tyres and when checking pressures they looked fine form the side profiles. Also due to the mileage and the state of the fronts I had no reason to suspect this. It was really shocking to see! New tyres goingon today and I'll get an alignment once rest of suspension on. I'll check bushes etc too. Thanks guys. No thoughts on Haldex issues causing this?

 

..No thoughts on Haldex issues causing this?

Don't think any Haldex issues would cause such a big difference between the left rear and the right rear.

 

Shagged rear shocks could make rears bounce excessively ?
Would have thought rears should last around 30k .
Just out of interest have you checked the date stamp on the tyres ?

 

How low is your car? Measure from centre of the wheel to the arch vertically above it and do both rears, 370 is standard 350 is facelift or sporty. They should obviously be the same, if the tyre is leaning in then inside tyre wear will result which is a side effect of being low and adjustable tie arms will help. If your trailing arm bushes have play in them then the tyre will move and wear will be uneven over the tyre surface. Also worth checking yer rear springs have not snapped at the end of the spring, difficult to see as the springs are small to start with but certainly worth checking. And don’t use that garage again as it sounds like they are way out of their depth when it comes to TT’s.

Good to hear it's probably not the Haldex. Had the tyres fitted today and got it on the alignment machine for a readout. Oh boy... Had a quick look and everything (springs etc) looks fine at first glance. I was on the way to work so wasn't going to get too dirty investigating. So here's the readout and toe and camber issues fully explain the tyre wear. Now I need to locate the source of the camber issues. I'll get adjustable lower arms anyway but I'll check the bushes at the weekend.

 

One thing though- the machine is a Corghi and it lists the options for this model quattro as Sport (2000-2006) or Standard (99-2006) and Standard (2003-2006). I assume as mine is a 2002 S Line with the 20mm lowering it is a Sport suspension...?

 

Yours will be “sport”.

Did they actually adjust anything?

 

Thanks, no not this time as I just wanted the tyres changed so that I can drive it safely to the garage etc. I'm changing all the shocks, springs, top mounts, lower rear arms so no point yet. I just wanted to see what it was like now untouched so that I knew if it was out or not.

 

 

Ok, so got the alignment done today after fitting new Monroe shocks, Eibach Pro -25mm (so -5mm on what I had) and cheapy adjustable tie bars. The garage reckoned he couldn't get the Proflex poly bush top mount thingies on properly so I'll try the local VAG specialist or diy if I ever get the time. Anyway, results as above. Drives good, but only been around town so far, tomorrow is the long commute day so we'll see.

However, while underneath, I spotted that the Haldex has a slight leak. Any ideas where to start looking? Had the filter and oil changed recently so could be that? And a spot of rust on both sides's leading edges of the sills. That'll need seeing to soon!

 

Whereabouts on the Haldex is the evidence of the leak? Near the filter, or near the filler / drain plug, or I think there's a breather hole somewhere towards the top end?

The way I put the new oil in mine was by inserting it upwards through the drain plug using a cartridge gun and then dropping the drain plug on the floor out of reach, shouting for someone to pick it up and pass it to me while holding my finger over the hole, then putting the drain plug back in the hole. Plenty of scope for getting oil around the place, but a bit off if it wasn't cleaned up before returning it to you.

 

 

Sorry, thought I'd uploaded them last night. Durr...

 

clean it up then see it goes. maybe it's leaking
