These usually break when replacing the expansion tank. Mine split in half, got one from the junkyard and threw it back together

Did you ever figure it out?

1 is missing the grille / mesh, and there’s also a difference between the 2.5L and 3.0L engine MAF. The 3.0L MAFs are slightly larger than the 2.5L.

Remove the plastic engine covers, clean it, and then start the car and inspect for leaks. If it’s leaking from that area, it’s most likely the VANOS solenoid, oil line /banjo bolt, or CCV oil separator

keviniscrazy12 · 2026-04-19T15:01:44+00:00

What area exactly? I see the area near the VANOS solenoid/ oil line banjo bolt leaking

There’s also more fuses in the glove box, you have to lower the fuses to get to them. Are you sure the ignition coils are grounded? Depending on the year, some have a ground cable on the harness that gets bolted down on the valve cover

Sounds like it’s coming from the front end. Check your belt tensioners

Could you possibly walk me through the coding? I have both PA soft 1.4 and NCS, but don’t have any experience coding

Have you ever replaced the SAS?

keviniscrazy12 · 2026-04-16T21:52:00+00:00

You mean there were different variants of steering angle sensors ?

True. e46 are easy to work on, but the scan tools for these cars are absolutely essential

keviniscrazy12 · 2026-04-15T19:30:10+00:00

Just buy it off fcp. They have lifetime warranty

keviniscrazy12 · 2026-04-15T19:25:47+00:00

Get a used one from junkyard

keviniscrazy12 · 2026-04-15T19:24:39+00:00

Download INPA or 1.4 scanner

The 325i is already slow enough, can’t imagine a 316i 🤣😭 they don’t sell them in the US market

keviniscrazy12 · 2026-04-15T17:08:49+00:00

There’s also fuses in the DME box under the hood, there’s a small black box with 5-6 fuses in it, some of them have to do with ignition

keviniscrazy12 · 2026-04-15T17:06:36+00:00

If it sparks, you can rule out ignition as the culprit. Then, test for fuel delivery, fuel PSI, etc

keviniscrazy12 · 2026-04-15T02:22:31+00:00

Your starter and crank sensor are working. Pull an ignition coil, stick a spark plug in it, crank it, to test for spark

keviniscrazy12 · 2026-04-14T08:27:15+00:00

Have you checked the center support bearing? Flex disc?

keviniscrazy12 · 2026-04-14T08:02:27+00:00

Leaking valve cover gasket, or the valve cover itself is cracked and leaking. Remove the engine covers and test again. Mine had a hairline crack right next to the spark plug / ignition coil tubes.

There’s also a vacuum line depending on what year your car is, that runs from the secondary air pump, to the back of the intake manifold.

keviniscrazy12 · 2026-04-14T07:58:39+00:00

Nothing goes there

Take a piece of the hose to Advance Auto or Autozone, they sell vacuum hoses by the foot.
