Hi all,

Well, I got my VAG-COM cable and last night tried linking the laptop to the car and after spending nearly 2 hours I finally did it. Note to other new users, make sure you pick up the USB to Serial drivers in the VAG-COM folder else the windows USB to Serial drivers won't work.....as I found out and had to search the laptop for the drivers !

Anyway, Did an auto scan and it came up with this on the engine.....

Address 01: Engine
Controller: 8E0 909 518 AA
Component: 1.8L R4/5VT 0004
Coding: 0011501
Shop #: WSC 63351
2 Faults Found:
16684 - Random/Multiple Cylinder Misfire Detected
P0300 - 001 - Upper Limit Exceeded - Intermittent
16688 - Shareware Version. To Decode all DTCs
P0304 - 001 - Please Register/Activate - Intermittent
Readiness: 0000 0000

I can't feel a misfire although it's a new car to me and might have always had it. Is it something I should be worried about or just a change of plugs ?

Thanks,

Richie.
