00 1.8T A4 B5 Startup Problem

[luism88]

Hello, this is my first post. I own a 2000 A4 1.8T Quattro tip-tronic. For about a half a year now, my car has been acting strange when I start it up. It happens when the engine is cold or hot. I scan it and no codes come up. The ignition turns all the way but it struggles to turn on. After 2-3 tries it turns on and no codes show up. The car runs excellent, all the tune ups have been done to the car. I have 160K miles all HWY, and just about everything on the engine has been repaired or fixed. I don't know what is happening. Can anyone help me please? Thanks

It kinda sounds like the Cam Chain Tensioner or possibly the ICM (ignition control module).

Do a little searching under those two topics and see if your symptons match. I'm sure some other people will chime in. If you could be a little bit more descriptive on the sounds or anything else you notice, it would help. $.02

Thank for the info. Well the sound is just the normal whinning when you try to start a car and it doesn't turn on. Nothing weird or special on the sound. I will research into the two things you said. I appreciate all your help. Thanks again

I do remember when it started to happen, the car gave me a code that said something about main electrical something, I dont remember the code number but I opened the box where the ECU is at and the big fuses in their, I thought was the problem. Went to Kragen, should of known they didnt have them. I just re-pluged them back in and vuala, it started up.

You can rule out the ICM since they were eliminated starting with the '00 ATW engines, which is what you have.

My car wouldn't start today and it spit out P1517 Main Relay Circuit, Electrical malfunction. What is the problem? Thanks

I don't have much knowledge about cars, but I will guess it's the battery.

Even though according to my car battery gauge says its ok? I know it hasn't been changed in a while
