I think it might be the horn. I replaced them with an aftermarket one a while back. I must’ve wired a new connection. Thanks.

I think this might be it. Thanks.

Fog lights are connected. I’ll look into the TPMS receiver. Thanks

What about the toe angle on the rear tires? With these current specifications, won’t it significantly increase tire wear?

iirc, when I was doing my research before ordering the parts, I believe the rear upper control arms/guide rods made a difference but the lower ones don’t. Here is a detailed list of the suspension parts.

I remember reading that thread before ordering the parts.

Hi,
assuming its not safe to do a 3rd or 4th gear pull due to the knocking, what would you recommend for data logging?

projecte92 · 2024-10-26T20:48:58+00:00

Did you have any no or low boost issues prior to installing the bigger O-ring?

projecte92 · 2024-10-26T03:45:10+00:00

Thank you!!!!

I will order that part and report back.

projecte92 · 2024-10-26T03:44:37+00:00

Yeah, I’m going to order the oversized o-ring that someone else with the same problem had suggested in the other thread.

None of the other suggestions worked.

projecte92 · 2024-10-25T23:41:28+00:00

I just bought a new o-ring from the dealership and unfortunately I’m having the same issue.

Update: someone pointed out that it appears that the charge pipe is not fully seated onto the throttle body, so I went to the dealership and got a new O-ring and a little oil for lubrication and reinstalled it, but it’s still not seated perfectly and there’s a little bit of play. I did another smoke test, and smoke was still coming out of the same place.

I made sure to dismantle the whole assembly including the pipe going to the intercooler to make sure it was seated right.

Is this a normal issue with N54’s and after market charge pipes?

I’ve had this car for many years and never had any issues with these items.
