    ". . .should last at least until BMW adds a dipstick to the 135. . ."

    Are you planning to live forever?

    When BMW brings the dipstick back (along with real tires & a self-maintenance-friendly approach in general), I'll be among the first in line. Many discuss Asian "appliances," but the BMW has turned into one as well -- excellent handling (of course), but an appliance all the same. One is expected to take it to the dealer for everything. The Honda I recenctly bought has lots of useful do-it-yourself info in the owners manual (not the service book), just like the old days.

    I read Roundel every month from cover to cover. It's clear that the people who write it and participate so enthusiastically are no longer the target audience for the current vehicles. The Roundel crowd are very much my kind of people. Those who pick things like dipstickless-engines & RFTs (& pinch pennies such that the oil level sensor isn't reliable) -- not so much.

    The Roundel crowd buys BMWs to drive.
    Sadly, most modern BMW owners prefer to wear them.

    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 RPM’s 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 isn’t even go 10 miles per hour. It has the same problem from second to third and so forth. In 5th gear I’m driving 70 mph and the car’s RPM’s 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.

    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.

    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.

    Thanks!!

    I just noticed that the guy who wrote that up has an '01 330CiC. That ~should~ look exactly like my '01 330Ci. I'm pretty sure that I suffered from temporary insanity and when I look again, I'll see exactly what the pics show.
  • kominskykominsky Posts: 850
    Looked again and I absolutely don't see what those pictures showed. I think I have a different setup or I'm really confused and shouldn't be working on my own car... ever! Here's a diagram from realOEM.com (a pretty neat site for finding part #s)...

    http://www.realoem.com/bmw/showparts.do?model=BN53&mospid=47713&btnr=11_2190&hg=- 11&fg=18

    It's part #21 on this diagram.

    Something happened to the link above and it no longer works. I did however find this on Pelican Parts' website...

    "Some cars came with mechanical water pump/alternator belt tensioner assemblies while others came with a hydraulic type. Note that the mechanical style is only available as an assembly - the bearing or pulley is not available separately. Therefore, it is important to identify which style is on your vehicle BEFORE placing your order."

    They sell the mechanical type and it looks like the one in the pics you sent, so I must have the hydraulic type. I'm still not sure how to "activate" it though. I managed to get the new belt on by manually swinging the tensioner... no easy task :sick:

    Sorry I couldn't be of more help. Spent the weekend in Indiana at a driving school and didn't have time to check back in... :(

    No problem! I appreciate the help you did provide!

    While you were learning/perfecting heel-toe downshifts, I was learning/perfecting a wide variety of new cuss words and finding out how much blood can pour from my knuckles before I pass out... :P

    For future knowledge, do you have any idea how the hydraulic tensioners work? I don't know if mine is faulty or if I'm faulty, but I could not figure out how to loosen the tension on the belt.

    Thanks!

    "While you were learning/perfecting heel-toe downshifts. . ."

    Mr. 'burner is probably too classy to mention this, but I'm not. He teaches at these things. Been around BMWs for a long time and a real asset to the boards.
  • kominskykominsky Posts: 850
    Cool!

    BTW, I can work with that too... While you were teaching heel-toe downshifts, I was teaching my 14 y.o. son, who was helping out, some new cuss words. :D

    As I understand it, the hydraulic tensioners maintain a more consistent belt tension due to the inherent damping function of the hydraulic cylinder.
