So, engine light been on a couple of times over the last month but as soon as is came on its been off again with the day. No real symptoms although power seems to fade slightly when on but cant really tell from a 1.6! And slight vibtation, rough when idle. Took her to bmw today for a diagnosis check and these faults popped up.

Smart Thermostats. Comments: I have a bmw e90 330i 2007 n54,which on cold start, runs extremely rough like several cyclinders are misfiring. Then 2 minutes later it settles down and is almost fine. I have replaced plugs filter coils and nox sensor and new vanos full kit. Cleaned Maf and vanos solenoids.

I have a 2007 BMW 328i with sports package 80K miles. What temperature does a NEW BMW/Wahler thermostat open? Mine might be failing because my car is running hotter than usual 228-230F. Other E90 and E92 owners think it's in the normal range, but it feels. The BMW 5 Series is the Ultimate Driving Machine.

Symptoms

Bmw E90 2ef7 Code

The customer’s complaint is that there is a loud rattling noise when the engine is first started. The noise heard is louder than normal for a cold engine. Shortly after the engine starts the malfunction indicator light (MIL) illuminates. (This is the same as the “Check Engine” or “Service Engine Soon” light.)

If you use a scan tool, the BMW fault code is 30C1.

Causes

There are three possible causes for this condition:

  • The oil filter housing may be collapsed.
  • Oil pressure control valve may have failed.
  • The oil pump may have failed.

Repairs

  • Check that the oil level is okay as an initial check.
  • If all is fine, then connect the AssistPlus and run a Quick Test. You should see a fault code in the engine management system: 30C1 oil pressure control, static.

  • The next step is to check the oil pressure using the Diagnostic Request button on the AssistPlus. The oil pressure should be 1.5 bar at idle when the engine is at operating temperature.
  • This can also be confirmed by fitting a special tool to the oil filter housing and checking the oil pressure with a gauge.
  • If the oil pressure is low, remove the oil filter housing and check that the oil filter is not twisted or collapsed.
  • After confirming the oil filter is OK, remove the oil pressure control valve from the side of the block underneath the alternator and inspect it for signs of blockage or pieces of broken plastic.
  • If there are no signs of a blockage, replace the faulty oil pressure control valve.
  • If you find blockage or signs of plastic, remove the oil sump to inspect the oil pump. Below is an image of what you may find after the sump is removed.
  • If you find damage like this, carry out a full strip-down and replacement of the timing chain, chain guides and oil pressure control valve.
  • Inspect the oil pump and VANOS solenoids to assess the severity of the damage found. Replace components as necessary.
