I have a 2001 beetle with 112k on it, no problems til 100k now it's all the time, the epc light came on and did all the funky stuff that came along with a faulty switch, replaced it ran fine for a day now the lights back on and the check engine light is on, when at idle it goes from 5000 rpms to 3000rpms to 6000rpms, any suggestions?
I have an 03' 1.8 T GTI with just over 100k. EPC and Check engine light was on... got it fixed it was the Engine Speed Sensor cost $450.00 to fix!!!!!!!!!!!!!!
Try a new alternator when the alt. power drops and increases you get a flaux in comp. which gives you sparatic rpms

It's fixed......we changed the brake light switch and disconnected the battery to clear all the codes, computer had to relearn itself and it's been running fine
I have a 01 audi a4 1.8t, Check engine light and epc light are on, car turns over and fires after about 4 or 5 seconds and idles at 1100. I tried unhooking the battery, it worked for a bit, but they are both back on.
