Ofhg gaskets and a thermostat to head hose

1nVasiv3 · 12-19-2018, 09:09 PM

As the title says completed a oil filter housing gasket replacement. Also replace the coolant hose from the thermostats in the cylinder head. Check for leaks everything looks good. Engine malfunction light came on when starting to hard accelerate.

Where should I start?

Read the codes. This will be your best first step. Most likely you just left off an electrical connector, so you could start with those as well.

If not electrical, did you loosen the intake manifold? You could have an intake vacuum leak. Again codes are your best first step.

Something to mention. It only sets off the light when I have stepped on it hard. Driving normal I was able to reach over 70 mph on a 45 minute commute when driving normally.

I did loosen the intake. The only electrical thing I could think of is the fan connection since I removed the fan during the hose install.

How can I get the codes? Will the parts store scanner be able to pic it up or do I need to go to a bmw shop?

Yeah as other person mentionned no codes doesn't help at all.

I guess you could go to the parts store and give us the generic codes altough it usually doesn't help much.

If not you would need something a scanner that reads BMW specefic codes. Or use BMW software on your laptop/computer, most popular seems to be INPA or ISTA in combination with a K+DCAN cable (OBD2 to USB specefic for BMW)

I already have the cable. Could you possibly provide a link with a download to that software that I can use to read the codes?

Sorry for the links you'll have to search yourself. The website where I got ISTA from got shut down.

Found the culprit, a small vacuum line was disconnected. The serpentine belt was starting to run off track so I pulled the old one, sprayed engine degreaser on all the pulleys and the front of the motor. Then pressure washed it all off. She runs like a top now.

Keep checking that belt...or replace for peace of mind. If you haven't yet, Google N54 serpentine belt issues and the damage they can cause.

1 Plus on this, just replace serpentine Belt, Tensioner, and Both Upper and Lower Pulleys for a piece of mind.

If that Belt Shreds, it could enter the Engine through the Main Crackshaft seal.
Then you are possibly looking at an engine replacement.

The DIY is pretty simple, if you DIY.
