#3899 of 5378 BMW 318i ENGINE RMP'S TO HIGH
Jun 13, 2008 (8:14 am)
I recently changed the engine in my 1995 BMW 318I. The engine that I bought has 78 thousand miles on it. When I changed out the motor, I also put in a new clutch pressure plate and throughout bearing. To make sure the engine is running right, I had an engine diagnostic test ran. I had to replace the map sensor and the oxygen sensor. After starting the engine and putting it into first gear the RPMís are why too high between first and second gear during shifting. From the time that I shift from first to second the engine is tacing at 4000 and the car isnít even go 10 miles per hour. It has the same problem from second to third and so forth. In 5th gear Iím driving 70 mph and the carís RPMís are 3500. Do you know what the problem could be?

Presuming your tach is accurate, sounds like you have a defective clutch.

Wanted to find out how much people paid for the BMW Service Maintenance Warranty for a 328 XI 2008 model. And is it worth it to buy one.

Jul 02, 2008 (11:03 am)
I have a 2001 330ci and is starts to have yellow engine warning lights for couple of seconds when I turn on the ignition and start to drive. Then it goes away and doesn't show up while I am driving. I've look the maual and it mentions about red light and blinking red lights. Yellow light is nowhere to be found. has anyone experienced this problem? What is the likely caues and how I can fix this?
Thnaks in advance.

Had the same issue last year on my E46. Dealership replaced a sensor (O2 sensor i think?) that was going bad. Before you go, make sure that you gas cap is on properly... I've heard that this could also cause that issue... Good luck!

Take it to Autozone and they will read the fault codes for free. No point in guessing when you can know for sure what the problem is.

If it's the yellow "service engine soon" light, then I agree with the previous reponses. If, however, it's the yellow oil "can" light, and your oil level checks out okay, then it's probably the oil level sending unit. I think it's a pretty common problem in these cars (my 2001 330Ci is suffering from the same thing). I picked up the sending unit from bavauto.com and will replace it during my next oil change. It ~appears~ to be a very easy fix... 3 bolts and a wiring connector... in the bottom of the oil pan.
#3906 of 5378 Cooling system refresh..
Jul 03, 2008 (1:29 pm)
I took a VAC day today and finally got around to doing my radiator, waterpump, thermostat, belts, hoses, etc. A couple of observations and a possible problem.
Nothing was easy to take apart! I guess 140K miles and 7 years helps parts create a nearly impenetrable bond.
Everything old was in amazingly good condition. Based on what I saw, it looked like the belts and hoses could have gone another 140K miles. Radiator was fine. Water pump fins looked good, but it didn't turn as freely as the new one.
The new parts all assembled very easily. I especially like the hoses with the built in clips so there was no dealing with hose clamps.
The problem: when taking it apart, according to Bentley, the main drive belt tensioner should have created slack in the belt when turning the nut clockwise. I turned it and it just turned, it didn't move the pulley. No problem I thought, and I just cut the old belt off. Then it hit me that I will have to put the new belt on. As of now, I'm not really sure how I'm going to do that. Any thoughts?
Thanks in advance!

BMW water hoses are remarkably long-lived. I still have the originals on my 1995 318ti. As for the tensioner, do these pictures help?

Looking at the pics, that's what I expected to see... that cast-in hex on the tensioner.. the tensioner for the auxillary belt has one. However, I didn't see anything like that on the main belt tensioner. It has what appears to be a bolt running through it at the pivot point (under a black plastic dust cover). Its pretty much exactly where the casted one is on the pics. Definitely not the one through the pulley, though!
I'm away from home right now but we're heading back tonight. I'll take another look around at that point. Hopefully I just missed something.
