2001 passat 1.8 coil pack help

Just bought four new coil packs for the car and the coil packs have 2 screw
holes to mount to block. Original version just popped in and fit snug.
The block has the hole bored but does anyone know what exact size I need to get them firmly installed. The car has been a nightmare, rough idle barely drives
without rough ride and bucking. Changed plugs, fuel filter, cleaned throttle body and last chance before sending to dealer is trying new coil packs from what I've read. Reading codes PO300,301,302,304 and PO171. Changing coils make sense with these readings?
Help !!!

Yes those are codes for misfires in cylinders 1, 2, 3, and 4 if I recall correctly. The bolt on coilpacks usually come with 2 allen head bolts her cylinder.

Thanks, took care of that and yet it still runs rough. Disconnected the MAF and still no change. Emission workshop comes on first minute then goes out. Runs smooth then bucks, any last suggestions before I get taken on labor charges at a shop? I even checked for Vacuum issues, none found.

Wish I knew more about the longitudinal 1.8T. I'd say check the coolant temperature sensor but I'm not sure if the audi 1.8T has the bad version.

I have the same problem currently. I was advised by my Audi buddy to check the Mass Air Flow Sensor. You can hook up a volt meter and test the voltage it is putting out. It should be around 11. I have a link in one of my emails that walks you through the steps on how to properly check the output of the MAF. I will get back to everyone on that.

Sure hope that is the problem, the MAF from the dealer runs about $220.00. I just bought one and will test the MAF myself this weekend.


Best Regards,

Well you called it exactly !!! Finally brought it to a local foreign car shop I trust after trying everything else to troubleshoot and save some money it was the MAF after all. The cost with labor around $300 so could have been worse.
After all I put in to try and save some cash, at least I know its basically ready to last awhile (I hope). The technician told me even though I put in after new market coil packs and copper plugs, eventually the car will act up down the road and to use Bosch coils and NGK or something plugs for those who might try to cut corners.
Thanks for you research, help and advise !!!!
