One thing I would add. on all the s55/n55 cars ive seen a handful of valvetronic motor failures. most of the time its on cars that were sitting for a long period of time. the motor will take out the 5v reference for a bunch of modules causing the car to go into limp mode with a bunch of faults. fairly easy repair.
Mines stock over a year back from bmw, bought on 39k now on 46k so not many miles for a 64 plate, just now I walked into a good few issues, coolant belt came loose causing pretty much everything coolant related to go, I’m no mechanic at all but they said it included expansion tank, pulley, thermostat etc and then they found a spark plug had gone whether that was the coolant getting into it but anyway 4k to fix :( but yeah even low milers can go wrong
It was 3.5k to be honest but yeah it was at bmw for 3 days they said they had to take the engine apart twice to fault find or some shit, I defo had my pants pulled down
Although it pains me to say this BMW ‘M’ division seems to have been run by the accounts department and the EU . Crank hubs , cam chains , bearing failures, minging cheap plastic components, the list goes on and on . That said it seems to be common place with most manufacturers except Japanese. We use s50b32 / 30’s and s54 lumps in our race cars and their awesome with very few issues. After seriously thinking about ditching BMW engines in my next car ( e36 GTR ) i think I’ve had a bit more faith in the new s58 . No drama informative tutorial guys 😇🇬🇧👍
Any advice !!! My 2017 bmw f80 m3 has sluge in my oil cap . However engine is fine I run it 150 miles last Weekend no overheating. No coolant loss . I've read its common if you only do short journeys witch i do. The engine doesn't get to full temps on my commute. .. can any help?
Man, I was going to buy and then daily drive an M4 manual convertible and I am now rethinking it. 😬. I’m from Lexus/corvette/Acura world where we just turn the key and drive. I don’t think I’m ready for this lol
@@BobbyDigital_100you should be fine if you keep the car standard. So many remap them and so end up running much more boost and the seals can / will start sling oil everywhere. My M4 is stock and staying that way for reliability and peace of mind
This video is missing one more fairly common problem - random/intermittent failures of ABS sensors which cause the car to lock differential and M modes. These may clear themselves or require a sensor to be replaced.
So check the following when buying a used m4: • Air conditioning on earlier model - pressure sensor fails, leaks from condenser or pipe lines • Seat belt recall on 2014-15 models • Check Rocker cover for cracks • check for Oil leaks • Crank hubs upgraded? • iDrive is up to date • Panel air filters are better • Ensure substantial pipework if after market pipes have been added as softer pipes can collapse under pressure • Have flaps been removed from exhaust • Has DCT gearbox mapped been done if remapped?
Yea 63k is still a baby lol. I drive a 2013 w204 C63. It is at 103k now, have had a few issues. I am thinking of switching back to BMW for the 6 speed. Looking at a 2018 f82 m4. Good luck!
I got a 2015, 85k miles now. Valve cover gasket needed to be replaced cus it was dripping oil onto the exhaust, gasket is $50 labor $700. 3 months later the car was making a hissing sound, found out valve cover is cracked now. So had to redo everything again, part was 500 labor same as before. Other wise been pretty good to me and I'm stage 2 catless for 25k miles and 15k miles on 100% e85
One this I disagree with his recommendations is to update the idrive. Many early M2c came with unlocked ecus and if you get your idrive updated you will be locked out of any potential tuning you may want. Uploading the idrive is not crucial since there is apple CarPlay.
I've got mine for 7 years with 85000km on the clock and had not even a single issue with it, I'm a member of bmw club in my city and have 2 friends that they have m4 competition and they're overly happy with their cars
I know of an M4 F83, now has 200000km on the odometer, and the only problem was 1 oil leak and vanos, other than the last no problems at all! And it is driven very hard!
why would you want to go faster in this machine and have it prone to issues.. keep it stock and spend the change on gold bullion, thank me later you kanjars
I have a m4 that has a no start issue after I had the starter Motor changed no one can fix it now says drivetrain issue and fault with my high fuel pressure it has a short to positive fault code 119001 can you help thanks
I read online that the water pump for S55 is mechanical but they have an electronic water pump for cooling the turbo. Does this mean if electronic water pump goes out you will not be left stranded on the road (assuming you take it easy)?
Should be similar to MHD, stock my m4 had 426whp, stage 1 with catalytic converter 487whp. Stage 2 was like 15 or 20whp more and without the cat it spools faster too
Hey ever since my gearbox has been serviced in m4 I feel the car jerking when I’m doing about 30 mph and the car is in 5th gear. Could you advise what the culprit could be and what do you suggest to inspect?
@@Gareth.kellyy sorry to hear you are experiencing this, few questions, was it ok before the service? What parts were used in the service? Was the correct drain and fill procedure used while carrying out the service ?
Great clip. Very informative as I'm considering purchasing one. What model year was the one in this video? Currently looking at a 2014 model so.for that year particularly what should look for regarding this car. Owned a few m sports etc but never an m model. Cheers 👍
It means …in a super expensive car where is the point to spend such a amount of money for so many problems…??? Better buy a Kia or a Ford Mondeo or even a Peugeot for a 1/3 of the price and go for a road trip around the Europe and save lots of money without any problems
Thank you for your input, but the Bmw M4 is a great vehicle, we as a company are just highlighting some of the issues that COULD occur, they may never occur on your vehicle or a vehicle, but its just a educational video to help and guide people who have one or are thinking of buying one. Thank you
You don't buy a BMW to be an economy shitbox. Especially not an M car. You buy it for the driving experience it gives and the performance that comes with it. If you want a dirt cheap economy shitbox, you're looking at the wrong company.
@@Soulvinum because they're fast, fun, and luxurious. And they're only really problematic if you don't take care of them. Once again, they're not shitbox economy cars.
Can you give me your input? I purchased a 2019 M4 with small front corner damage, only 18k miles. I repaired the car and when I drive the car, transmission slips on all even gears, odd gears work perfectly. When I repaired the car I did replace the transmission cooler, did have to top off transmission with 5 liters, then I noticed the problem, I flushed the fluid and did when programming with ISTA car could not set adaptation, says problem with clutch. Can the clutch be worn prematurely with only 18k miles? What can the problem be?
I just had a problem with the DCT. Had to replace mechatronic unit and clutches, cost me 8500£. Car has only 37000miles, no upgrades at all! Did anyone experience similar problem with those?
I am about to buy one but I also have a Lexus GS 350 that my wife drives and I have an IS 350 that I drive. I know it will give me problems because I have owned about 6 BMWs in the past but not ///M cars. Had the B58 and n54 motors. B58 was the best. Either way, I am keeping my lexus because as soon as it acts up, I have the lexus to keep me moving. 😂 Getting convertible. So, even more problems. 😅
Wondered if you have come across the sound going? I have a 2018 m4 Comp and started the car today Idrive came on but no sounds from the radio or apple car play? If that’s an easy fix can try buy if it’s more complex then may need a garage - any tips much appreciated 😊
All hardtop convertibles E series and F series, water builds up in the rear quarter panels get filled with rain water, the drain plug at the bottom under the side sills, about 6 inches in front of the rear tires. The drain plug is blocked by the 2 under panels..and u will hear water sloshing around over time, it can short your speaker amp and blow your electronics! I just emptied mine on both sides!
You missed the very common leaking diffs due to the diff seals. My m2's diff is pissing oil out at 18k miles. So so many people have this with low mile M cars.
This sounds like almost every problem I had with my E-46years ago. I switched to Mercedes and haven’t looked back. However, I’m considering buying a second car as a toy and the M4 seems like it’ll be a lot of fun… when it’s working 😅
No lexus is comparable unless you going LC500 territory..eats petrol..hell expensive and still slower. Reliability will not be much better. You cant have it all if you buying highperformance sports cars.
Drove my 2015 m4 convertible for almost 40k miles, at 87k now., Only issues I have are the typical valve cover gasket needed to be replaced at 85k miles, cus it was dripping oil. Then few months later the valve cover needed to be replaced , it was hissing cus cracked
