2018 BMW X5 in for a clunk and washer fluid leak

This car has just shy of 62,000 miles and the passenger lower ball joint had excessive play, so we swapped it out with a Genuine BMW part.

Unfortunately for our customer, the washer fluid pump had failed which requires fender removal to gain access. This was also replaced with a Genuine BMW part for a perfect fit

This 2019 Audi A5 2.0T came in for a proper diagnostic of a P0420 Catalyst Efficiency code. With only 85,000 miles on the clock, it was better to be sure than to figure out a sensor or leak was to blame after spending money on a new catalyst.

The computer was right though, the catalytic converter was on its way out. This customer opted for an Integrated Engineering higher flow downpipe to complete his IE intake setup, while still passing emissions.

We got him setup and gave him back his old part in the new parts packaging for future use!

If you own an Audi/Porsche with the EA839 Turbo engine

The factory spec 0W-20 doesn't belong in it, at any power level. 0W-40 or 5W-40 are recommended in all conditions at any mileage in order to prevent premature wear and tear on your favorite ride.

The EA839 3.0T V6 (and possibly the 2.9T) found in Audi and Porsche models might not suffer from what we consider traditional bore scoring, but bank 2 major thrust side are having problems with piston skirt wear. We're sure the factory 0w20 fill doesn't help! Time for some Driven DI40!

And if you aren't sure your engine is affected, bore scoping the cylinders is a surefire way to make sure your engine isn't affected, followed up with regular used oil analysis to make sure your engine stays healthy.

The Volkswagen dealer couldn't figure it out, another independent Euro specialist was just guessing.

Flotron got it fixed

This 2015 VW Golf GTI came in with a problem that conventional shops run away from. Intermittent stalling issue only after more than 30 minutes of driving, and it'll only do it once or twice then it won't do it again until you cool the car down and start the cycle again.

The dealer said spark plugs and coils, no change. Then they said O2 sensors, no change.

The customer then brought it to a supposed Euro specialist independent and they suggested it was carbon buildup.

There is a theme here..... neither of these places did any real testing. An educated guess, while valuable, doesn't get the job done.

Then the car made its way to me. Step 0 revealed no obvious answers, so the only option was to replicate the customers concern. After driving many miles, I was unable to get anywhere from the data right off the OBD2 port, so we go further.

Once again we go back to the fire triangle. One is missing when this issue occurs, and with new Genuine plugs and coils installed I turned my attention to fuel.

I put a fuel pressure guage on the low side fuel line and continued my testing.

Bingo. When the car gets hot, randomly the low side fuel pressure will drop to 0 with ignition off. The fuel pressure regulator on the fuel pump assembly has failed.

A new Genuine VW fuel pump installed, and that's the end of this problem for our amazing customer.

Flotron Automotive is appointment only to better serve our customers, walk-ins make for a less effective Step 0. Get in touch, lets talk about your cars issues and get you going.

PS: There are parts of the diagnostic process left out intentionally. A magician doesn't reveal all his tricks.

2022 Audi S5

This customer came in because their driver window wouldn't roll up and made the worst of crunching noises when running the switch

Luckily Audi Kirkwood had a window regulator in stock and we got this swapped out quickly for him.

This customer also wanted to switch to an E40 tune, so we installed a Fuel-It! content analyzer and a larger high pressure fuel pump piston to handle it, along with getting him switched over to E40 correctly.

2019 Volkswagen Atlas of one of our amazing customers in for an Adaptive Cruise Control (ACC) fault.

ACC systems rely heavily on sensors positioned with degree accuracy to do their job. When a sensor determines it's out of alignment, it can shut the whole system down as we have here. Not good for someone driving down to Florida soon!

How does a sensor get out of alignment? Potholes, bumps, damage from debris on the road, or simple sensor failure can all cause issues with ACC.

Luckily for this customer, a pothole simply bumped their grill out of position. We reset the grill into place with measures to keep it there, and reset the misalignment values in the vehicles software.

An oil change and some filters wrapped this Atlas up for our customers trip!
