2016 MINI Cooper Engine Problems

The malfunction indicator lamp light is on (MIL) with the following fault code stored in the DME: Fault code Control module Fault code text 1B8302 DME LIN bus, communication (EAC sensor): missing Problem verified. Don't know if car will quit on the highway. Mini recall for exact problem and extended warranty to solve the problem only on the "S" model with the exact same engine.

Drivetrain error occurred. I pulled codes and found P0015. I added oil, cleared code. The next day the drivetrain error popped back up. Pulled codes and found P0366. I took the vehicle to mechanic for diagnostics and to find the issue. They found faults: 130F11 and 120408. When replacing engine oil and filter, they found metal shavings in the oil; bearing material. They are recommending replacing the engine. Doing research, it appears this has been a common occurrence with these vehicles/engines. Is there a current recall on some of these engines, or a possibility for a discounted replacement due to the issues being widespread? The car has less than 74,000 miles, and the mechanic said it looks like it may have been going on a while. I purchased this car from a used dealership less than 3 months ago, and have already encountered so many unexpected issues. I really expected more from the Mini brand. Thanks.

Oil filter housing failure. MINI issued a recall for this part in 2014 when the third generation MINI Cooper S/JCW first launched. Unfortunately they did not fix the part and now as time goes on, the issue is occurring with high frequency on every BMW/MINI and Toyota Supra with the BMW B46/B48 2.0L turbocharged engine. The plastic oil filter housings crack causing oil and coolant to leak. In my case oil poured down the front of the hot engine which could have caused a fire. BMW/MINI dealers charge nearly $2500 to repair this failure. The ODI should investigate this concern as it has been reported dozens of times on each model with this engine including the BMW X1 28i/M35, BMW X2 28i/M35, BMW X3 30i, BMW X4 30i, BMW 328i/330i, BMW 528i/530i, BMW 330e hybrid, BMW 530e hybrid, BMW Z4, Toyota Supra 2.0T, MINI Cooper S/JCW 3-door and 5-door, MINI Countryman, MINI Cooper S/JCW Convertible, etc. BMW is aware of this common failure. Thus far BMW has refused to issue a service campaign or recall for this problem which causes owners of these affected vehicles to be out of pocket thousands of dollars. If oil drips onto hot exhaust or into a wiring harness, it could easily cause a fire.

My Mini service adviser said the timing case cover is seeping and will continue to get worse until the seep becomes a leak and the oil starts dripping onto the manifold, potentially creating a fire. It is at the seepage stage now and therefore my extended warranty will not fix it. My Mini service adviser said she doesn’t think it is dangerous yet but I have to keep an eye on it as this is a common problem on Minis. They quoted me a price of $934 to replace the timing case cover itself. I researched the problem online and found this is a common problem and will need my attention to ensure it doesn’t get dangerous before I’m able to get it repaired.

Notes from Beckley Auto Service from 2-12-24. "Verified warning light on, retrieved one code for LIN bus communication fault for environmental air catalyst sensor. Checked and found technical service bulletin (TSB) from Mini Cooper M13 01 19. The chemical composition of the fan shroud contaminates the sensor. This repair involves the replacing of the radiator with each sensor and fan shroud. Should be covered under Mini Coopers emissions warranty. Called Mini Cooper of Des Moines(Jerimiah) and was advised that this vehicle does not have and extended parts warranty/warranty extension on the environmental sensor. Would recommend contacting Mini Cooper Customer service or Mini Cooper North America for assistance." I did contact Mini Cooper customer service North America and was told my vin does not fall within this TSB. When asked why my vehicle with the identical engine and issues specified in the TSB is not covered I was told, "I don't know."

Had recurring engine warning light which will only reset for one ignition cycle. Took to dealer to read code and result was "LIN bus communication fault for environmental air catalyst sensor". This is the same problem drivers of the Mini Cooper S model have reported and received an extended warranty from Mini of North America (15 year / 150000 mi) with replacement of sensor and radiator. However, talking with Mini of North America, the extended warranty does not apply to the base model 5-door Cooper because not enough complaints have been recorded. If more people report this issue, it could be covered just as the S-model is being covered. In the meantime, the car will not pass an emissions inspection with the light on, and Mini dealer wants $2000 to replace radiator and sensor. Car currently has about 70,000 miles on it, but engine light as been on for approximately 15 months (emissions inspection is required every 24 months). I have a decent code reader, but it only provides "U019D generic code" which is why I took it to Mini dealer.

Transmission-get message when opening car door to put parking brake on to secure vehicle from rolling… Car does not roll, goes into gear with no problem… on the mini message board a lot of owners getting the same message….

The harmonic balancer aka crank damper went on my 2016 4dr hardtop 1.5L Mini Cooper. Has 73,000 miles on it. It has been sitting at a garage now for almost a month waiting for bmw to have the part in stock (tentative date avail. Sept.20, making it 2months wait time) tried every possible 3rd party parts dealer & not 1 harmonic balancer is to be found. I was told this part had already needed to be upgraded & modified making it a faulty part to begin with. Was told by garage it’s a common part to go on these cars. 1st my warning light came on saying the battery wasn’t holding a charge. Beings that I was 2 blocks from my house I drove there & as I was getting to my house another warning came on saying “carefully pull over & let engine cool” so I parked it & had it towed to garage to avoid any other issues.

Check engine light comes on. The vehicle is giving code 1b8302. This code is for environmental air sensor BUS communication error. There is an extended warranty issued by Mini for other models for the exact same issue. Dealership/Mini will not cover the cost to repair my vehicle as it has been excluded from the extended warranty. I would like to highlight again that the warranty was issued for the same issue I am experiencing. I have the same engine and the vehicle was manufactured during the same years the warranty was issued for. My vehicle has less than 44,0000 miles on it. There is clearly a defect. I would greatly appreciate any assistance you can provide in holding Mini accountable.
