My front suspension became ˜5cm higher after servicing replacing suspension parts. I just bought a Touareg V8 2009 and the front suspension had wear on the bushings of the arms and I decided to replace them (lower and higher arms) on both sides as I like a smooth ride. I bought the parts from a place that sells remanufactures arms (Touareg/Q7/Cayenne) and supplied these parts to a repair shop who mounted them for me. The car became as new, (no noise and steering well) but I noticed (a few days later) that the front is higher, you can visually see it (approx 5 cos / 2 inches) as well as the headlights shine too high now. The repair shop (not specialised in Touareg) already had thrown away my old parts and did not notice any difficulty in mounting the parts nor noticed any change (wrong parts) , all steering parameters are OK but the fact is my car's front is higher, I also noticed that the car is blowing off compressed air from the suspension all the time, tsssh! Can anyone tell me what happened? Did I get the wrong parts or is there any sensor mounted wrongly that keeps the car in this awkward position. Please help as my "new" car is now sadly enough weird... Thank you!

No definitely that's not the case. I drove already 4,000 km with it. The vehicle is balanced left<->right but not front rear - I read something about calibrating the suspension via a VAG control unit, is that the case?

Yes. If they disconnected the front ride height sensors and either did not re-connect them or did not re-calibrate all 4 sensors, that could explain the problem. Especially if the system is releasing excess air pressure all the time.

A VW/Audi specialty shop should have VCDS (Ross-Tech: Home) and can do this for you.

But I actually recommend buying a unit for yourself. It will save you money in the long run.

stuff snipped...

What happened is that the people who worked on your car did something wrong.

Find a mechanic who knows the Touareg well, and pay them to fix the problem. Soon.

That compressed air is coming from somewhere. My guess is that your compressor is making that compressed air (d'oh) and it's working overtime. You risk burning out the compressor if you don't resolve the problem soon.

yes I know, but I am a member of this forum not to hear to go to a mechanic and solve the problem. I think that what happened is that the suspension was changed (with or without lock) and needs to be calibrated using the VCDS. I am looking for a cable 12.12 here in Brazil. The Ross-Tech software is freely downloadable?

The software is freely available yes. If you do not purchase the genuine VCDS cable, you will have extremely limited functionality though.

Here is the only place to buy a genuine cable:
Ross-Tech: Home

I strongly recommend buying it directly from them. Their customer service is AWESOME!

And of course, if none of us buys the genuine cable, Ross Tech will cease to exist.

My initial Ross Tech purchase, almost 15 years ago, was one of my best automotive investments ever. :)

So you want us to diagnose the following situation for you:

- you purchased remanufactured parts that *might* be the correct ones for your vehicle
- an inexperienced mechanic installed those parts and now your air suspension is FUBAR

Maybe there's a 13mm wrench jammed in the strut. Maybe they installed the parts upside down. Maybe they tore one of your front airbags, or did other damage, or left a hose or sensor off a valve body. Maybe what you thought was broken initially wasn't. Maybe the parts you bought were defective. Maybe they weren't the correct parts for your car.

Kinda difficult for us to diagnose remotely. Sometimes it can be a challenge to diagnose a problem when all of the above is a possibility.

Go find a good mechanic who can figure out what's wrong with your truck, and save you from burning out your compressor.

Have you priced a compressor?

You're not driving it now, are you?

You are a *new* member of this forum. You asked for advice, you got it. You didn't hear what you wanted - i.e. "fix this."

Here's some more advice -- Touaregs are very expensive vehicles to own. While you can do some of the work yourself, you cannot take short cuts. Short cuts will cost you far more in the long run, and sometimes even in the short run...as you're finding now.

By the way, "wear parts" are probably not the place to go cheap. Remanufactured control arms or tie rods may not have bushings of the same quality as OEM, so you may be replacing them again soon.

Find a good mechanic and develop a relationship with him (or her :) ) I've had the same private mechanic for 25 years and we maintain my cars in partnership. I do some stuff, he does everything else. Except for unusual performance stuff, he sources all the parts he uses...and he knows up front that he's got the right parts. And when a coolant expansion tank on my allroad cracked after being installed 10 months earlier, he replaced it at no charge through Audi's parts warranty.

@ steijntr

The above post is very sound advice.

From time to time you will need a good mechanic who knows Touaregs well . . . like now.

And do buy a proper licensed Ross-Tech cable.

Buying a "cable" and downloading the "free" software are two entirely different things. The software needs to see the key from a genuine Ross-Tech cable (or wireless device) in order to work correctly. There are no more VCDS "lite" versions anymore.

It's a little expensive, but WELL worth the $$$. As mentioned, excellent customer service via their forum. The forum Moderator will usually respond personally to your inquiry if some of the other forum regulars don't beat him to it.

Get a proper VCDS and post an autoscan here (or the Ross-Tech forum) and we can go from there. Otherwise, we're just a bunch of people flapping our jaws in the wind....
