Hello, my car listed above BEV is having some serious issues. I can drive it about 5 minutes before it will lose power and stall out. Starts back up just fine but stalls out much quicker. It also, in my opinion, gets up to operating temperature quite quickly. I have VCDS scanned it and it revealed 5 codes. I have replaced upstream and downstream o2 sensors, engine control relay, MAF/IAT sensor, ECU, wire harness, crankshaft position sensor, spark plugs etc. Codes are P1118, P1198, P1433, p0113, and P0102. I replaced all but the secondary air pump and relay. All replaced parts are from OEM suppliers. I am stumped as to what could be the issue.
Do you
have the same problem?

I am thinking you have a wiring issue or controller issue. However, we need to make sure you don't have a vacuum leak as well. Here are guides that will help with this:

Once we confirm there is no vacuum leak then we need to check the voltage supply wire at the mass air flow sensor. I highlighted this circuit and as you can see it goes to the o2 sensor, secondary air pump, and other major sensors as well so with all the other codes that you have this is the most likely issue. Specifically we need to check fuse 43 and make sure that is not blown.

Let's run through this material and go from there. Thanks

Thank you for the diagrams of the circuit. That being said. I already extensively checked and fixed as many vacuum leaks as I could find. When I bought this car it had a nasty vacuum leak in the brake booster. I replaced that part and checked the old one just to discover that the previous owner punched several hole on the back top edge of the housing. My assumption is that they did this to force the engine to run richer due to the problems im currently trying to fix and they didn't want to spend money to fix it right. I also replaced that entire harness, that those sensors are connected to, along with the fried with ECU because the previous owner also direct spliced a downstream o2 into that harness. It has a used harness so I will recheck all the wires just incase I missed something. I have replaced the relay numbered 428 near the brake fluid reservoir. I am waiting on the other relay, that's next to it, to arrive. Is fuse number 43 in the driver side fuse panel? If so I will get a new fuse for that tomorrow. I will be in touch again once I check for more vacuum leaks and for damaged wires. I did notice on the fuse block atop the battery the thick red wire next to the black wire for the starter in the picture im sending looked corroded and was warm to the touch. I do not know what it goes too.

If that large red wire is warm to the touch then we need to pull it off at both ends and check the resistance of just the wire. That large of a wire should have very little resistance so let's check it and make sure it is less then a half ohm.

I attached the info for this wire and the fuse 43 for you. It is in the fuse panel on the left side of the IP.

Thank you for your help. I will check this wire and that fuse. You have been so helpful. I have been struggling for three years and talked to nearly 50 people about this and got nowhere. Thank you so much. Those 30a fuse s178-s180 are those special order or can I find those anywhere?

They should be pretty standard. I would suggest removing one and taking it into a parts store just to compare it. A fuse is a fuse so as long as it is the same amperage and will fit in the holder then it will work.

Thanks for the kind words. Please keep us updated with what happens. Thanks
