BMW i3 REX

A great example of this is the replacement of the KLE (charge module) in a 2015 BMW i3 REX. The process requires careful handling of the high-voltage system, which operates at 380 volts. Disconnecting this system properly is crucial to avoid any potential damage. There’s a special procedure to follow when disconnecting the high-voltage system, as simply pulling the safety disconnect connector may cause significant damage to the high-voltage relay (master switch). This is due to the risk of arcing, which can damage the switch’s contactors.

What makes this process even more critical is that the system only allows for a limited number of disconnects before the high-voltage switch can fail completely. Once the switch is damaged, it may no longer work, leaving the system inoperable. That’s why we make it a priority to stay up-to-date on the best practices in the industry. We attend specialized courses that teach the proper procedures, and we ensure that our technicians receive factory training materials for the best possible results.

BMW Diagnostics

In addition to our technical knowledge, we also invest in the best diagnostic tools available. We use factory-specific hardware and software to ensure that we can update and re-flash all onboard computer systems. By connecting directly to the manufacturer’s server, we ensure that all software is the latest version, giving our customers the most reliable and efficient performance from their BMW i3.

The winter is almost over, but you should not change your winter tires yet. There is a down side to driving on all season tires on snowy, icy road. Some of our clients find this out on the hard way. A small mistake might be very costly.

Every driver should know: Smaller the tire’s tread, smaller its biting edges and your tires will have less traction. For reliable braking and cornering performance at winter driving condition, on wet, snowy and or even icy road, you need good quality winter tire, not worn down all season tires.

The weekend weather took it’s toll, one cracked AMG rim. The replacement rim cost $1570.00 from MB, one bent alloy for late model 530 BMW cost of replacement $1230.00 + alignment.

How do you check a rim for any possible damage?

New wheel has arrived nice and shiny. Now the question remains: How do you check the other rims for any possible damage? In our high tech world, we have solution for almost everything. Meet our laser guided 3D tire balancer, check the next video out.

Yes, there was one more rim which is wobbly for now we made the best out of it. We do this all the time. To be able to make a smooth ride you need a precision machine which can pinpoint rim or tire defects and recommend match-mounting by dismounting the tire and remounting it to a specific spot on the rim to bring the highest point of the tire to the lowest point of the rim to get it close as possibly can to perfect.

Let me note it: This is our second machine of the same made. We use the first one about 20 years. Yes this balancer is 23 thousand dollars but precision and technical innovation has its price. We actually take it one step further by marking each wheel with their precise run out. It goes like this, the best wheel to the left front, 2nd best to right front, 3rd to the left rear and worst is the farthest away from you the driver.

Naturally when your wheel looks like the one on the video, with the multiple bubbles are toast, unsafe unfit for any use.

One of our other clients, bent his AMG suspension driving on summer performance tires. Even though his car is a 4 wheel drive, it was no match for the weather.
