Need help with Coil packs and vag com error

[NeedHelp14]

Hello, 2005 Audi A4 1.8T Quattro, 167,000 KM. Changed all 4 coils about 1 1/2 months ago. Spark plug were change at about 120,000 KM Got a CEL light on and had friend scan with VAG COM with following: Address 01 ------------------------------------------------------- Controller: 8E0 909 518 BC Component: 1.8L R4/5VT G 0040 Coding: 0016711 Shop #: WSC 93246 3 Faults Found: 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 008 - Implausible Signal - Intermittent 16687 - Cylinder 3 Misfire Detected P0303 - 008 - Implausible Signal - Intermittent 16685 - Cylinder 1 Misfire Detected P0301 - 008 - Implausible Signal - Intermittent Readiness: 0000 0000 Address 46 ------------------------------------------------------- Controller: 8E0 959 433 BB Component: Komfortgerát T7B 1612 Coding: 11848 Shop #: WSC 06335 1 Fault Found: 01560 - Passenger Door 59-10 - Can't Unlock - Intermittent Any ideas what I should check. I read here to clear code, change around coil packs and then rescan. (Will have this done today). Also read to smoke test to find vacuum leaks. Does anyone know where to smoke test and at what location in engine to start from (At friends place now and he is asking me). Also, told to disconnect MAF and see if codes go away and only left with MAF code. Any other suggestions
