I have an 01 a4 quatro 1.8t...65k miles. I was driving and the low oil pres. light came on/it also had a check engine light on. I stoped by auto zone and had them check fault codes. All that came up where,missfire on bank 1,2,4,@lean fuel. I drove it home/about 20 miles. And as I pulled in to my drive it died. Then an epc light came on and it wouldn't start. It turns over fine,all pullys move fine no odd sounds or anything. So I am sure its not locked up. I checked the oil pressiure and its ok. But it dosn't have any compression? I am not sure what the problem is or what to chek next?

Also the cams,and valve all look good.

if theres no compression you might want to do a compression check on all cylinders

If there is no compression, sounds like you have a broken or skipped teeth on the timing belt and bent some valves. Besides broken belts, the belt tensionser assembly has a history for failing, letting the belt loosen and then skip teeth. Skipping belt teeth will cause the same damage as a broken belt.

put the key on the on position and see if the epc / check engine light .. light up.. if not it could be that your ecu is fried
