(Pt 2) Beautiful BMW... STILL BROKEN?! (No BOOST: 335i Twin Turbo)

After installing the new OEM Exhaust Camshaft Position Sensor, it's time to button up this 2009 BMW 335i Twin Turbo, and take it on a victory lap to make sure all the BOOST is back!
All DONE, right?
Not so fast...the Beautiful BMW has more surprises in store! Uh oh...

[@basshunter428]

When the move from mechanical timing to computerized engine management was made, the door to expected failure was flung open. Auto manufacturers want you in their shop as soon as the warranty runs out and they know you will be! Great video, Ivan!

[@eppson9778]

As a 335 guy, I recommend you leave the cover on. Tendency for water to get in the plug/injector well and causes nightmares. Additionally, the injectors are incredibly loud and the cover does and excellent job killing the noise. But taking the roof off the house might be worth it.

[@reneneron2971]

Ivan, 2 comments: 1) I suspect the mouse is still in the car; owner should investigate further. That is possibly why the nest returned. 2) recall that you had at least one coil with corrupted wiring. Car may have has an intermittent misfire on that cylinder, dumping raw fuel into that cylinder. Would not take much to result in fuel contamination of the oil. Fuel contamination destroys the lubrication properties of an oil, so regular oil changes are a must (time OR mileage…twice a year regardless).

[@reneneron2971]

Had a squirrel store a years supply of acorns in the intake air box of a 94 Camry that was stored outside in PA. Used the air inlet tube below the air cleaner as a tunnel. Didn’t notice anything until the air filter element was removed and discovered the box chock full of acorns.

A lot of these case studies where cars break down unreasonably early is because the clients don't take their car on a nice long drive. If you are the kind of person that lives 10 minutes from their work and their grocery store and everything, go for an hour long drive once every two weeks or so, and do one wide open throttle pull from a stop to the speed limit to take the carbon off the valves and rings.

[@badgerdave22]

Thanks for the short series, Ivan! I always appreciate your honesty by even keeping your "mistakes" (measuring the wrong signal wire at first) on your videos so the rest of us can learn. Hope you're having some nice autumn weather over there in PA. As always, looking forward to your next video.

[@JoseSilveira-newhandleforYT]

Weird that the intake sensor only failed after the exhaust sensor was replaced! Almost like ECM magic - programmed obsolescence? Great job, Ivan! Good to see the BMW back on the road.

[@jyao5409]

I am wondering about that as well? Could it be pin tension on the connector? Is it legal for a car maker to program a failure? How does ECU know a new sensor is replaced?

If I were working on it I'd of said it was just impossible and there must be another cause. Talk about a hair puller.

[@calholli]

Exactly... something is very fishy here.. I don't like it one bit

[@calholli]

That's interesting.. but it doesn't explain why the intake signal looked perfectly fine before it could run the test.. and then after the test could run, it had that floating signal? Why would it only fail AFTER being tested? It's very strange. Unless the test purposely hits it with high current and causes it to fail if it's too old? IDK.. but it's very strange to catch the before and after fail signals like that.. What a coincidence.

Some things I have learned from eotking on German cars: Use a code scanner that can read all proprietary codes for all modules and can do adaptations/recoding. A generic OBD II scanner doesn't do much for you. Get a used oil analysis to check for engine wear. Change all fluids including brake tranny, and differental on aregular schedule.

[@yelloradio]

Thanks! I had the eco mod for my Pilot for a few years and never installed it, concerned with engine heating. Thanks to your video I installed it and put it on a switch. This way I can turn it on or off depending on my needs. Around town and such I leave it off, on the straight highway I’ll probably leave the ECO on. Now knowing it doesn’t impact the fan cooling thresholds, I’m happy and it is wonderful having a smooth operating car.

Same issue on RAV4 parked outside. Use 3 oz. of Peppermint Oil extract in a gallon of water with a pump sprayer, srpay engine bay and undercarriage down. May not eliminate but will definitely help. Need to do it every 2 weeks. If parked in garage simply tighten up garage. Great video! Thank you.

[@Dave-dm3xs]

Good diagnosis and video. I would suspect the sensors failed due to oil contamination caused by the petrol content. Very common on direct injection engines with very few oil changes. I would think its also affected the VANOS units. Not only does petrol in oil kill sensors, but also wet belts, ask Ford and Stellantis in Europe. By the way, modern BMW's now time out the brake pads regardless of how much material is left, and you can't just reset it as big brother knows you haven't changed the wear sensor...got to just love modern cars

It needed catalytic converters. It is a SULEV Super Ultra Low Emissions Vehicle. It had 15 year 150k mile warranty. They ended up giving me a 7500 dollar estimate on my car. I asked about they warranty. Service advisor laughed at me. Well I'm outspoken and it took me to literally yell at these morons. He brought a paper down that was printed out by my vin number with all of the parts that were under coverage on my car. He claimed because the part numbers on his system were different that it was not covered. Guess what. They all were covered and they did 6k in work. They only replaced 1 cat. Claimed the other cat was corroded and corrosion was not covered. Even though the BMW warranty manual had a section in it which says what is not covered and corrosion is not listed. I said what BMW not design to drive on snow?

5:10 Programmed obsolescence is NOT why one code pops up after another code is fixed. The reason is enable criteria. The test for the intake cam sensor synchronization can only run after the test for the exhaust cam sensor runs and passes. That's the reason why you didn't see the synchronization code at the beginning of the video. Because one test is dependent on another in order to run.

[@FridolinMeier-h7l]

The reason for the two bad sensor at the same time is the combination of high amount gas in the oil and low mileage. So the gas will difuse inside of the sensor housing and destroy the sensor. And I would also think there is another reason for the gas in oil. A bad injector or something like this.

[@Law_Abiding_Citizen_ok]

Car ‘over fuels’ ( old fashioned choke if you will) on a cold start up, and any excess fuel will cling to cylinder walls ( especially on failed start ups) and fall down past piston rings as it is less viscous than oil and end up in sump/oil, if you do not drive more than say 30-50 miles then oil is not gonna get up to such a high temperature as to vaporise off the fuel ( you call it gas🙄) that is now mixed into the oil.

[@MrTonyPiscatelle]

@@Law_Abiding_Citizen_ok Why would a modern engine fail to start? I've never had one fail to start and never had one shut off while its cold on its own. But have had plenty of carbureted cars and trucks that did and many that were cold natured and hard to keep running and would flood out in a heartbeat. Have to realize I've been driving for 50 years and also worked on cars way back when.

[@YZJB]

Because when the engine is cold, the cylinder walls are cold. Fuel condenses on the cold cylinder walls and washes down into the sump. GDI is worse for this as the fuel has less time to mix with the inlet charge, so there’s a higher chance of fuel droplets condensing on the cylinder walls.

[@MrTonyPiscatelle]

@@YZJB Nah nah nah. Fuel would be near the same temp maybe even colder. And if the engine isn't 300 K ring worn that ain't going to happen. Unless you've been cranking on it for 30 minutes and the injectors have been firing the whole time. Then you'd get cylinder wash down .

Place Bounce dryer sheets liberally under the hood, wrap around wires. I use a fresh box of 240 sheets every time I park my car. Some in the interior as well. This was recommended by Consumer Reports and it works. I drive a truck and leave my vehicles unattended at work often for over a month at a time. I’ve lost a under hood wiring harness and fuse box, and a nest was made in the heater motor in a Chevy pickup, and a mouse nest on top of my Honda fit engine made from the hood blanket. I used to use mothballs and had some on the battery of the Fit. The mice crapped right beside the mothballs.

[@JamesAgans]

So when you dry your clothes do you throw in a couple of mouse traps? Lolol😂😂😂

[@razor0razor]

If sensors are pull down type (they provide zero volts on signal line) and ecu is pulling the signal line up when sensor puts its output into high impedance then this might also be ecu or wiring (mice) problem. Way to check is to measure voltage on signal line with sensor unplugged, if there is 4.7V then sensor has nothing to do with that voltage level floating. So oscilloscope capture is good for showing to customer, but definitelly not 100% conclusive.
