While regular maintenance is not required it is advisable to check how much the chain has stretch, say every few 100K. If the chain stretches too much the tensioner may no longer be able to perform its job. There's also the problem of the pins becoming a bit loose in the side plates. The chain should also get a visual check whenever the opportunity presents ...

What is a shock absorber? I'm going to answer the basic title question with a carefully selected quote from the great Wikipedia: ... their intended sole purpose is to dampen spring oscillations. Think of how you want your car to ride when driving down a smooth road that has a bump or pothole. You expect to feel a mild jolt when the car travels ...

Sounds to me like your starter motor is on the way out, as you are getting enough power, as a bump start is working, and sometimes you are able to start normally. This isn't that uncommon - they do take a lot of stress and load, and the internal friction can end up being too high for them to cope with. A temporary fix I have used in the past is to whack ...

Model number differentiates the power (and usually size of the engine) of the car. You can often expect that car with a larger model number will have better optional equipment (it is valid for BMW 7 series models, perhaps series 3 and 5 have the same tendency). Models with bigger engines usually have different (stronger) suspension and stronger brakes. They ...

Red one is likely to be for a pull hitch. If you get stuck you can insert a screw with the hoop on the end and it will allow someone to pull you out with a chain or winch, putting load in the appropriate place (not the bumper). The screw device is probably in your trunk somewhere. From the owners manual

On most bikes the carb has an overflow port that drains through a tube to the ground. This is important if the float sticks. Usually you can tap the float bowl with a screwdriver and unstick it, but if it happens again, overhaul the carbs. Also, don't smoke around a bike that's dripping gas.

The very first thing that you should check is whether you actually made a mistake and, if so, which one. A cap that says "ATF oil only" is for automatic transmission fluid. If you're adding engine oil to the transmission, that's going to make your transmission very unhappy. It is fixable: you'll need to drain the transmission fluid and replace it. If ...

As other people have already pointed out, the warning light is the oil pressure warning light so you really need to get to the bottom of this, especially if the light comes on at any other engine speed than idle. I think the culprits - especially if the problem started shortly after an oil change - could be (in decreasing order of likelyhood): Oil ...

You have probably already done this, but check your oil levels or you may end up with a seized engine. The "red engine oil" light is a a warning that oil pressure is too low, which is usually caused by lack of oil. Brian Knoblauch in the comments below points out that a faulty oil pump can also cause the oil pressure to drop.

You probably have a wheel out of balance and it's difficult to determine that without putting the tires on a balancer. One thing you could try would be to jack up the car and put pencil on a stationary object like a brick or a board move the pencil so it almost touches the wheel, spin the tire and look for the rim moving in and out in reference with the ...

The e46 has a central jack point in the middle/front of the car, between the front wheels (red circle). Just make sure you use a block of wood between the jack and jack pad to help distribute the force a little.

If you are not familiar with the electrical system I would get a referal to a good shop familiar with BMW's. They may have seen it before or at least recognize what caused it. This a case where it must be determined if your melted wires were the cause or the result of another problem. Just installing another harness may result in the same melted wires. The ...

The best BMW e46 manual that you will likely be able to purchase is the Bentley e46 technical guide. It's big, heavy, and expensive ($75 to $100) but it's well worth it. While you might be able to find information online about a particular repair procedure, but this manual covers everything in detail, with lots of diagrams and pictures. It's so much better ...

My bike does this every couple of years after storage over winter. I have found that the float obsorbs some fuel and thus the level overfills. I have adjusted it some (hard to get right on mine) but the best bet for me was to replace the float. Either way, it should NOT drip or leak fuel. I have not seen any BMW at the shop I worked at leak except as I ...

Yes but as of present there are no US based tuners that provide a DPF delete kit or engine tuning (reprogramming) to allow the safe removal of this device. They exist overseas in the UK and Europe but I would hold off until someone in the US provides a product specific to the US car. Also the US spec 335d uses a DEF (diesel exhaust fluid, adblue, urea ...

You should be able to get the battery changed, either by an automotive locksmith or by your nearest BMW dealer. The batteries are usually standard coin cells, but I wouldn't try changing one without checking first as you might find it will need to be re-programmed afterwards. Try a locksmith first as they will probably be a lot cheaper than BMW!

I know my vehicle is equipped with a battery load monitor. When the computer (I assume the body control module) senses a load above some factory set value for more than 10 minutes with the engine off, it disables the power circuit. To reset it requires cycling the ignition switch. Turn the key to start nothing happens, turning the key a second type returns ...

Simple answer - no more or less than other cars of their era (late 80s - early 90s). That was the age when cars started to get more complicated and electrical, so they are harder to fix than the previous generation, but much easier than a newer car with loads of electrics. The engine is all fairly accessible (especially if you get a 4-cylinder 316 or 318) ...

Go with the recommended oil. The manufacturer should know much more about the vehicle they designed than your mechanic friend. Here are the factory recommendations for the E34. This covers all engine options that were available for the E34 chassis. Viscosity : Cold climate: 5W-30 Mild climate: 10W-30 Warm or hot climate: 15W-50

Have the shop do whatever it takes to get the wheel off. Lug bolts are readily available and not too bad in price. If it's a lug that requires a special key and decent mechanic should be able to remove it even without the key. Some shops will tell you that it may damage the wheel in the process but as long as they pay attention to what they're doing then it ...

Manufacturers do sometimes use epoxy resin (or something like that) to attach spoilers and fenders. Mostly because it doesn't require drilling, which is a weak spot where rust can start to form, but also to form a nice aerodynamic seal. But then, you can never trust a secondhand car dealer and it may be that they had stuck on a wing/fender that had come off. ...

Not sure on your 330, but on my E39 the the battery in the key is automatically recharged when it is in the ignition. There's a clever induction system that keeps the battery charged. Your battery may not work that way and may have died. You may also have somehow gotten the car security system to "forget" your keys, so it isn't responding to them any ...

Do you notice any smoke when this misfire happens?It is possible that you have a leaking injector. The injector may not be holding fuel pressure after the engine is shut off.When this occurrs with a hot engine the heat of the piston vaporizes the fuel.When the engine is cold the fuel sits in the cylinder and causes a misfire on start up until the cylinder ...

A lot of BMWs have a noise, but it might be a pump going bad. If I remember right, the lines are right under the reservoir. Check them for softness, and if they are soft/chewy I guess you can replace them. If it's a pump, run until it pops, as they are like $400. As far as the lines from the rack, those are hard lines, and unless clearly pinched not sure if ...

Regular maintenance is not needed. However, a "rattling" noise that changes with engine RPM may indicate a problem with the chain or timing gears. Usually this isn't an issue until higher mileage (150k +). Next time you go by your dealership, ask them if they've had any problems in particular with your year model. If you hear of instances of chains commonly ...

It's not a service manual, but you can get technical drawings and parts lists from realoem. But if you're planning on doing anything beyond changing your wiper blades, get the Bentley manual. Sure, it's expensive for a book, but if it saves even one hour of a BMW mechanic's labor costs, you'll still come out ahead.

IF you have an E39 with an M54 engine, it is as easy as: Unplugging Battery Unplug cable, and possibly unscrew rail Unscrew each coil pack, and replace Reconnect all items, and test drive Not a very hard job, as all the packs are exposed once you remove the cover.

Two possibilities occur to me: a too-large turbo or a too-loose wastegate. when I press the accelerator there is no power until the rpm tachometer reaches 2500 This almost sounds like the replacement turbo is too large. when I press the accelerator there is no power until the rpm tachometer reaches 2500, then I need to release the accelerator ...

The ICV (Idle Control Valve) can be cleaned once removed. But, it should *not* cause the vehicle to backfire. It sounds like you're dealing with a large vacuum leak. Here are some things that you should have a look at. After checking for any obvious vacuum leaks around the top of the motor, the Vanos & Crank Case Ventilation System should be next on ...

When water comes out of the overflow tank, my first reaction is that you have a head gasket leak. Not all such leaks mix oil and coolant. One failure mode is a one-way leak (due to pressure) leaking exhaust into the coolant; if this happens, the gasses in your cooling system have nowhere to go but out the overflow tank (which is not tightly sealed, unlike ...
