#Bmw m3 kompressor manual#

Once installed, the hardware looks stock. I am going to have to redo this step and may have to remove the power steering line from the car to properly bend it. I got the piping to fit but some components are rubbing together, causing a squeaking noise at low speeds. The terse instructions and poorly lit picture for this step did not help. Cutting factory harnesses is almost never a good idea (particularly when the connector cannot be ordered by itself) and I am surprised that ESS did not go with the much simpler (and reversible) t-tap approach here.Īnother challenge was bending one of the high pressure power steering hose to allow fitment of the piping from the intercooler to the intake manifold. Fortunately, I discovered that I could t-tap into the wires on the harness to attach this new connector.

The only thing I really disliked about the kit was the (apparent) need to cut the MAF/IAT connector from the factory harness before connecting the new IAT connector that came with the kit. I spent 2-3 hours trimming these parts, with the bumper trimming taking the most time. The stock power steering reservoir bracket also need to to be modified to work in the reservoir's new relocated position.

For example, the bumper, undertray and left-hand-side brake cooling duct need to be trimmed during the installation The manual does not include trimming templates - so you are on your own. Several stock parts also need to be modified during the installation, a process that was also time consuming. (The injectors are custom Siemens ones developed for ESS but use the same o-rings as the stock injectors.) I suspect I spent close to 6 hours alone dealing with injector issues. I also damaged an o-ring on one of the ESS injectors during the installation and had to order a new one. Properly aligning the fuel rail and injector components before tightening is also tricky. The fuel rails to injector clips and the electrical connector clips can be a pain to work with until you get the hang of them. In particular, I had a bear of a time installing the injectors.

I have a fair amount of experience working on other cars but not so much on my M3 (oddly, it has been as reliable as a Honda during my 8 year/40k mile ownership) so a few things were time consuming. Unless you are familiar with working on M3s, the 6-8 hours installation time mentioned on the main product page might be optimistic. Overall, however, the instructions are pretty solid. The manual also combines steps from several different kits and generations (VT1-475 & VT2-525/550/575, generation 2 and 3), which can cause unnecessary confusion in places. A negative is that some of the pictures are not as well lit as they should be so a few steps can be confusing. The supplied installation manual is very comprehensive and has detailed step-by-step instructions with accompanying pictures. The individual components are well packaged and everything is of very high quality.
