Well that is a lot of electrical codes. Has he tried clearing them to see what comes back? I would check the battery and ground. Old batteries cause all sorts of problems, so check it's voltage too.

Do you have a jb4? You might not have gotten the lid back on the DME wiring box and water may have seaped in. Check all of your fuses as well.

You are getting water somewhere. I had all those codes happen after a 24 hour rain storm. My amplifier was literally sitting in 1" of water.... Water was leaking in through the tail light.

Thanks for the responses so he has tried clearing them but no luck they all come straight back i've also had a new battery within the last few months. I'll get them to dig around the car to check for any signs of water leaks. Anymore advise would be appreciated. Also i had the windscreen replaced not so long ago i'm wondering if the plastic cowling was not put back on properly and correct me if i'm wrong but the ecu sits just under that so would make sense that maybe water getting into ecu although i've never opened the ecu and supposedly its water tight right

[weehe126]

ECU sits under the intake manifold. There is a box with some fuses and wires on the passenger side that can be exposed to water if spmething wasn't seaped right. I would start pulling fuses in the glovebox and see if anything is blown.

Sounds like possible water damage, or maybe a bad ground.

It says you drive a 330d? If so you posted this is the wrong section.

[C15exy]

Apologies for that my last car was a 330d i've had the 335 for around 2 years now.

Hello!
What you are describing sounds almost similar to what happened to me. After an hour or so of troubleshooting, I found out that my charge pipe had somehow gotten unhooked which caused my car to struggle to stay on and have a really rough idle and throw a code for my MAF Sensor. Maybe check your charge pipe and see if there is any leaks or it that it may have gotten loosened somehow?
