BMW E60 Intake Boot Replacement – 2004-2010 5 Series – M54 6 Cylinder

Repair Summary
The following article gives detailed instructions on replacing the one-piece intake boot on a BMW E60 5 series car with the M54 six cylinder engine. Even though we have used a 2005 BMW E60 530i to perform this repair, this article can be applied to any BMW 3,5,X, or Z series vehicle with the M54 inline six cylinder engine with minor modifications.

A BMW E60 intake boot repair may be needed if your vehicle is displaying the SERVICE ENGINE SOON light on the dashboard, "Increased emissions!" warnings on the iDrive display, and engine code faults 2882, 2883 2986, and 2987 on your diagnostic scanner.

One of our favorite vehicles here at the BMW Repair Guide is the E60 530i with the M54 engine. It's a great car and is still one of our most favorite-designed BMWs ever. Unfortunately for us E60 lovers, the earlier ones were plagued with electrical issues that have taken their toll on their owner's wallets over the past few years. Another issue that E60 owners are encountering is that many of the plastic engine parts, seals, and gaskets are starting to age, causing them to become brittle and leak. As we wrote about in our article Rough Idle Repair - E60 530i, gaskets and plastic parts in the engine compartment are beginning to fail, wreaking havoc as they allow outside air to penetrate the closely metered flow en-route to the intake manifold.
At this point, we are going to stand up on our pulpit and pontificate on the necessity of purchasing a smoke machine/leak detector for your garage. One of the biggest repair bugs BMW owners are dealing with these days is vacuum leaks in their vehicle's intake system. The intake system is a spider web of plastic and rubber parts, so pinpointing where the leak is coming from can really only be done with a smoke testing machine. A visual inspection rarely will reveal the leaking part. We know...not what you wanted to hear at this point. But before you leave our article, please consider this: a trip to the dealership or independent shop to find and fix your intake system leak will cost more than buying a decent smoke machine and doing it yourself. We guarantee you that's a fact. So why not buy your own so you have it for future home repairs? There are several "non-commercial" machines on the market that will get the job done: if you are interested in purchasing one, we have provided links below in the Tool and Supplies section.

The BMW Repair Guide uses the Vacutek EVAPro smoke tester at its facility.
That being said, one of the most common intake system leaks comes from the intake boot. The intake boot connects the air filter box to the throttle assembly and is at the heart of incoming air into the engine. The intake boot is mostly comprised of corrugated rubber and plastic that tends to crack over time. Unintentional "manhandling" of the intake boot while doing other repairs in the engine compartment can also cause stress fractures and loose connections. Due to its large size, it always seems to be in the way of some repair on the left side of the car.
A BMW E60 intake boot replacement is a simple job for the DIY mechanic. ***Please be aware that if you currently have a dashboard and/or iDrive warning messages on, you may need to use a diagnostic scan tool to clear them after the repair.

  ***Important notes concerning BMW E60 intake boot reassembly*** It is very important that the new BMW E60 intake boot is correctly attached to the throttle body before you tighten the metal clamp. Doing this for the first time can be frustrating...many mechanics think they have the boot attached, only to have it fall off when they tighten the clampdown. There is a very easy trick to this. First, there are two tabs on the throttle body that match up with the two slots on the intake boot. Make sure they are lined up when you install the boot to the throttle.bmw e60 intake boot repair - match up the intake boot slots bmw e60 intake boot repair - match up the throttle body tabs Then, while keeping the boot level and lined up, push firmly. You have to push the boot on until it "snaps" into place on the throttle body...and it takes a little bit of force. But once it snaps into place you will know because you will not be able to easily pull it back off. You can now tighten the metal clamp.bmw e60 intake boot repair - push intake boot onto throttle body At this point, you can go ahead and reassemble the intake system following the above directions in reverse.
