I have 3 panel lights that will not go out since I had my oil changed on 2002 Volkswagen Beetle

I had my oil changed yesterday, they told me everything was fine with my car and that they would recommend the next time I get my oil changed to do a full system flush. After leaving I notice that my check engine light, my ASR, and my EPC light were on. I took the car back and they hooked it to a little computer that gave the guy two codes, he said the engine code was nothing was wrong and then it went out and they EPC was nothing and ASR was nothing to worry about. I left to go home and when my husband went to leave a little while later he said the check engine light was back on? This has never happened before with the check engine light after getting my oil changed. The oil light has come on before and I took it back to the dealership and they said the computer has to reset itself and that it will correct itself but I have never had my EPC, Check Engine or ASR light come on before and stay on.

If you would tell us what codes they are that would help.Could be a vacuum leak. There are a few vacuum hose connect to the air intake.They maybe left off something? I hope not the solvent got inside of Electronic Throtle Actuator!

I believe the numbers were 102 and 145.

The DTC P0102 indicates that engine was started whithout the air mass meter was connected . The P0145 occured most likely from the cleaming solvent or the process of cleaning itself. I wonder what are the codes now.
