Everybody welcome back, Mark with Exotic Carr Play Place, standing in front of my illustrious e60 m5 today. Today we’re going to talk about the 5 Series BMW’s and the most unreliable, that top 5 most unreliable 5 Series BMW is on the market today as a used car purchase. Before we get to that though make sure you check out the description below there’s a link to my Shopify channel, I’m selling many great shirts you’ll love it. Check it out. But let’s get rolling, so into the top 5 most unreliable 5 Series BMWs. Today starts with number one, it’s the e60, the 2007 to 2010 E60 535i and why is that such a problem? While it shares a lot of the great attributes that the 335 has as in, it’s basically one of the favorites for the tuners, but that all comes with some challenges. We know these cars come with a straight 6 3 liter engine twin turbo charged with producing 300 horsepower and about 300 foot-pounds of torque, but because it was BMWs new kick at turbo charging, yeah they had done that back many years ago, but they were getting back into the turbo charging game, the e60 generation in general had a lot of complex electrical concerns and issues to deal with, but on top of that, it also had high pressure fuel pump, which coincidentally lost BMW lost a class-action suit and BMW ultimately anteed up to honor 10 years and up to two hundred thousand kilometers of warranty to get that resolved for many, many customers out there today. It also had issues like leaky valve cover gaskets, leaky oil filter gaskets, fuel injector issue, to interpose the problems themselves with the turbos, and the Radley wastegate issues that were an annoyance for a lot of owners as well, so it had a host of mechanical problems and these problems in a lot of cases you would even, I’m under warranty but sometimes they actually recurred, so it was a problem time and time again just as the 335 was with the same n54 twin turbocharged engine. So the second most problematic 5 Series BMW goes of course to the car behind me the e60 m5, featuring the v10 the S85 v10 that produces 507 brake horsepower at about 383 foot-pounds of torque. While this thing was an absolute masterpiece, f1 derived engine, f1 sounding engine, that’s why a lot of enthusiasts still love it today, was able to attain over 200 miles per hour, but that all came at a cost again because the e60 generations had a new level of electrical complexities, those were problems for these cars, but on top of that it had a lot of mechanical problems as well, and some of the mechanical problems start with things like the idle throttle actuators, we had double vanos issues, where they start making noise, rattling of course, vanos pumps we’re a problem, the high-pressure pumps could be a problem, and the lines could be a problem, those are all issues and very expensive issues. Some of which could actually write off the entire value of the car. Of course there was also gearbox issues, we had problems specifically with the SMG 3, we had problems with a differential, but the king the granddaddy of problems came with you know 60, 7,0 80 thousand miles on the odometer for these cars, rod bearings, a filthy problem. A problem that was consistent through almost every single e60 m5 I know. There were some owners out there that didn’t see as much of an issue, but there were consistently high volumes of cars that sustained rod bearing either failures or premature wear, and this of course is the primary reason why this car makes number 2 for the most problematic largest number issue 5 Series BMW’s. And so the third most problematic 5 Series BMW again goes to another E60 and E61 model, of course the touring model, goes to any of the cars that had the N47, the four-cylinder turbo diesel engine that was one of the entry level based diesel engines that were available on the market in those eras. The n47 engine had a a catastrophic issue related to it, it actually had two failure modes, two significant fatal flaws with this car, and one of which of course was the timing chain failures, timing chain failures, of course synchronizes the valves, and the Pistons make the car run properly when that synchronization goes out of whack, like they often do when the timing chain breaks. This is called an interference engine, you have collision between valves and pistons, resulting in immediate stoppage of the engine, and often broken parts scattered throughout the engine, catastrophic problem N47 turbo diesel engine that was available in the 520 D of the e60 generation, that was a real big problem. Another fatal flaw with that car, was the fact that it actually had the timing chain arrangement was on the firewall, so you couldn’t even change the chain for relatively small cost as a preventative measure, it was a significant cost even to pull the motor out to replace that timing chain for those who actually felt compelled to get ahead on the maintenance on that particular car. So it was a very costly thing to preventative check on, and it was even more costly when he started hearing that rattling noise and the car instantly stopped, shut down, went dark on you. That usually meant you had a catastrophic engine failure which was very, very common in that n47 engine. Another little issue that you had a design flaw on the n47 engine, was the fact that it had poorly lubricated wastegate springs and hardware, so often what happened is the wastegate would stick, usually stick open, which is probably safer that way it stuck open so it’s essentially, it would flush most of your boost out while you were driving, resulting in a loss of power as well as poor fuel economy, this was recognized early on, and a lot of these cars were rectified of this issue, although it was a problem. So the fourth most problematic 5 Series BMW of all time goes to the e39 m5. Enthusiasts loved that car, it had a 400 horsepower v8 engine, strapped to a six-speed manual gearbox, it was one of the last of the old-school generation BMWs that was more mechanical than it was electrical, and that’s why a lot of people love that car dearly, and that’s why those cars and the values are going up today, but unfortunately it is an M car. A lot of them are driven hard and as a result here is a list of issues you can find within e39 m5 rod bearings. I know the e60 m5 gets all the rhetoric around it, but the e39 also had a lot of the cars I’ve come across had rod bearing replaced because they also have problems. There was also suspension bushing issues, sticky brakes, I noticed a lot of these cars on the used car market, now I’m finding with rust on the round, the rockers, the gas cap door in that area, you’d also find sometimes rust around the rear quarters. They had rust. Don’t forget they also had a dual Vanos system which could also act up and cause you expensive repairs as well. These cars were also susceptible to carbon buildup, as well that would also result in you know kind of plugging of the intake system, the valve system, and as well of course O2 sensors were also not uncommon to burnout. So you would have a host of engine lights, it was also the kind of car not unlike the e60 m5 where every time you turn the key, you sort of flinched and hoped you didn’t see that magical engine light. Other than that, it was a spectacularly great car to drive, and still is today, and that’s why it fetches a still a significant dollar. The car has not reached beater status, so just understand because it was an expensive car in its day, it still has expensive repairs associated with it. It is an M car. So the fifth most problematic five series car goes to the e30 530i and that car was produced in 1992 to 1996, and that happens to be the car that had 215 horsepower v8 strapped to either an automatic transmission or a manual 5-speed gearbox. I’ve got to warn you first, not a great power plan to begin with, when strapped to the auto, it’s a very sluggish feeling gearbox, and the car wasn’t really that sporty feeling, plus it’s kind of heavy, so you always want to buy this car with a manual for starters. Well where this car became a problem was other than the usual barrage of electrical failures, windows coming off the rails, or you had host of other just generic issues, you also had valve cover gasket problems, water pump problems, leaking, but most importantly the liners of the engine were consisting of nikka cell and the high sulfur content that was in the fuels of those eras, take a real toll on that internal parts of the engine, thus reducing the power over time in the car internally, essentially started to corrode and wear away, and you reduce compression, you lost power over the years, that wasn’t a great car to have because the internal, the guts the nickasel, if you can find the car later on with the Elsill lining, that was a much better option, but generally because the early deterioration of the internal lining of the engine coupled with the weak automatic gearbox, and host of electrical problems as well some leaks on the front end of the motor. This was easily in my books one of the worst cars available in the 5-series market today, on the used market of course. So everybody I really hope you enjoyed the video.
