Top 20 2005 Audi A3 - Page 6 Questions & Answers

Cost about the same, your going to have to replace the heads on the engine and most likely replace the piston that the valves were being hit by.
This would be a total engine tear down to repair, there are shops that say no and just run the damaged pistons which will work. But it's just a meter of time before a connecting rod or pin fail causing another engine tear down.
More economical to replace the whole engine with new internal parts. Thank you for using fixya and good luck, you can also upgrade your engine by using timing gears instead of the belt. But it will be loader, since you'll hear the gears whining.

Could be a fuse or a relay prob. Hopefully it's not an indicator stalk switch problem (expensive). If your hazard warning lights switch works then it's not the fuse or the relay. If your A3 is still under warranty then get your Audi dealer to fix it. If not it won't pass the 'MOT'. Get it sorted before someone rear-ends you while you're turning!

I just loosen the bolts of the subframe and use a bar to pull it down abit , while my lad changes the bush, or you could pull it down a bit and block it with a bit of wood, so you can change the bush safely.

First you must air bleeding out from inside hydraulic clutch acting system ! On the slave cylinder you will find an aeration screwed ventil provided for air bleeding. See picture below:

I have the same issue, I can't figure out with is causing it.... Help!!!!!!!!!!!!!!!!!!!!!!!!!!1

Turbo vehicles often sound like they are whistling when the turbo spools up because it is sucking in air at a high rate and it makes a bit of a whistling sound. Generally not a problem unless it is a different whistling that you are referring to.

It's difficult to find intermittent battery drains, but I can tell you from past experience the most likely things are 1. the trunk light staying on sometimes. If you can access the bulb, remove it and see what happens. 2. the hood light, same solution. 3. aftermarket alarms and car starter are often the culprit. Hope this helps. I think the window problem is unrelated. The window motor probably is bad. Sometimes you can get lucky and make it work by banging on the inside of the door near the bottom while holding the switch down. If this works, it's definetely a bad window motor.

you can try alldatadiy. that may have the information that you need.

On the inside trim, you can remove screws (these screws may be covered by filler pieces or may be visible, or they may require you pry a plastic piece off that covers the screws) that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. Then you'll need to manipulate the panel and disconnect the door handle linkage from the door handle and disconnect the wiring for your controls.
