Question about 2000 Audi A4
Hey my name is Nick and i just purchased a used audi a4 1.8T. The engine coughs and shakes when cold and when it warms up it runs fine. The guy i bought it from said probably a vacuum hose. any ideas? Also the driver information display doesnt work any ideas as to how much this will cost? is it even necessary? i bought the car cheap and am just wondering how much of a pain in the *** its going to be to fix some of these problems. Thanks for your help and time. firstname.lastname@example.org
Hey Nick, what's up? OK, here's how I see it:
The coughing and rough running could definitely be a vacuum hose. As to which one, it's anyone's guess. The only way to find it is to inspect every line and see if any are cracked, unhooked, or dry-rotted. You can replace them with new black hose (or colored silicone hose if you want to dress the motor up some). I'd also recommend a Seafoam treatment for the car. Here's how to do it:
That stuff can make a world of difference. You might also consider a new coolant temperature sensor. They're around $20 or so, and not difficult to change. Here's how you do that:
As for the driver information display, those are very expensive and unfortunately they're also known to fail on these cars. I've heard numbers like $700 to get a new one. You can get a replacement, donor cluster from another car, but it has to be calibrated to your car's ECU. If you're going to do this, I'd buy it from a place like www.shokan.com - they're an Audi salvage yard and offer guarantees on their parts, so you would have some sort of safety net if it didn't work right. Check with your local dealer to see if they can sync the cluster with your ECU before you buy though. And if it doesn't bother you that it's out, you can leave it alone completely - it gives you outside temperature, tells you which door is open, etc, but I don't believe the vital functions are included (I'm not positive, as my 99 A4 doesn't have it).
All in all, if those are your major headaches, then you likely got a good deal. You'll love the car for sure. You should come and join www.audiforums.com - there's a whole community of enthusiasts there and you'll learn a lot about your car. If you do, look me up - my screenname is "UpstateNYA4".
Hope it helps!
