BMW M3 Convertible Engine problems by year

service was not available anywhere. Recommended services by the dealership: - "replace rear coil springs with lower pads. (Both rear coil springs are broken) note: - although, we 'd like to make this repair we did not agreed to do so. - The tag price scaled to us766.28 Without tax and we've been in a tight budget. - You may try searching online for "bmw rear coil springs complain, issue or problems." There are literally hundreds of complains on bmw's rear spring fail but still not recall, ( although by bmw own admission this should be consider a serious safety issue. *Tr

shoulder but with no luck as the vehicle went back into neutral. The cars behind me came very rapidly and two almost hit me as a result of this pump failure. By this time I was traveling around 40mph in a 65+ traffic zone. I finally rolled my car down the shoulder to safety. I replaced the smg relay with a spare new one I always carried in the car. I waited 10 minutes for the vehicle to cool off as I knew this was the infamous smg pump issue. The car started back up with no light and drove me almost the entire route back home. Just about a mile from my home, same thing happened. This time leaving me completely stuck in a busy intersection. Luckily, the people behind me were kind enough to help push my car out of the way. I called a friend and we pushed the car all the way back to my garage. Now this is just the first time it has happened. It happens in less than 3 minutes of driving the car just when I try to move it never breaking 15mph. Bmwna ignores our complaints as their dealerships make money hand over fist with this $4000 repair. My complaint is not with the repair amount. Us m3 owners are aware of the maintenance and repair costs for our highly specialized vehicles. However, this pump malfunction is a very real danger to all drivers. We've seen this happen to vehicles with anywhere from 15k to 120k miles on them. Bmw needs to issue a recall. *Tr

Unplugged the "mass air flow sensor": car started, displayed no warning lights, drove fine about 8 miles to repair shop. Code read shows, "throttle position sensor", replaced..Same problem within minutes of driving. A little internet research on e46 finds this an all to common problem with no solution. Thanks in advance. *Tr

radiator end tanks, and water pump impellers or bearings. (Bmw came up with an improved water pump design around 2004 that is more reliable.) Cars with automatic transmissions also suffer failures of the mechanical fan clutch and the transmission cooling thermostat. Failure of the fan clutch (found only on automatic transmission cars) can cause the fan blades to break off and damage the radiator, serpentine belt, and water pump, as well as the car's hood. At higher mileages (>150,000 miles) the plastic coolant pipes often fail, causing overheating and requiring major work to replace. On my car the coolant expansion tank and radiator both failed and were replaced. The thermostat also stuck open resulting in lower gas mileage until it was replaced. Now one of my plastic coolant pipes is leaking. Bmw should be required to repair failed plastic cooling system parts on the e46 3-series with higher-quality parts designed to last at least 10 years and 100,000 miles from manufacture date. *Tr

of "stalling" has happened much more frequently when the ambient temperature reaches above 90 degrees, and now I cannot drive longer than 30 minutes without the smg mil turning on and gears start dropping. I'm concerned that this may happen at higher speeds and leave me stranded on a highway or even in stop-and-go traffic, where it seems to occur very frequently. I've researched many forums for this and have found this to be a common issue with other m3 smg owners. There is some indication from other owners that the issue might be linked to a hydraulic temperature sensor located on the main smg hydraulic pump but I have not found any information from bmw detailing a repair for this type of issue. The only option seems to be a full replacement of the hydraulic pump, which has already been done on my vehicle once before for a similar issue. This type of replacement costs almost $4000 as quoted by the dealer. I think bmw should get serious about this issue and conduct an investigation on potential campaign remedies. *Tr

On halloween night 2011, as I was leaving the gas station, I hear a very faint rattling noise up in the engine bay. I was contemplating rather I should take the car to the local dealership, or fix it myself. But prior to this, I've read many unsatisfying experiences people had at their local bmw dealerships. I worried that since this was a major problem that could be life threatening, I decided to do the work myself. I removed the valve cover, and noticed the exhaust side hub on of the bmw double vanos has failed. A mechanism designed to improve torque and fuel consumption. The hub had one of the 2 tabs completely broken off. Luckily the broken tab was still stuck inside the oil pump. If instead the broken piece came out of its location, and moved around in a engine this could cause a catastrophic failure. Ranging anywhere from approx $15,000 remanufactured engine replacement to possibly a high speed collision if the car was in motion during the failure. With a damaged engine, it is difficult to follow the minimum speed limit of 40 mph on the local freeway. The total replacement parts in my situation costs well over $3000 using bmw parts. Unfortunately, even with the current replacement parts from bmw, the problem would not be fixed since the currently new parts have just as much chance of failing as the old. *Js

$10,000. The car hammered to a stop. Bmw is refusing to acknowledge the issue suggesting out of warranty. My concern is that I have 60k on the car when the issue occurred first. A p0011 camshaft timing fault comes up. A bmw service center cleared the fault and replaced some coils and sparkplugs ($663) and sent me on my way. Three days later the bolts sheared. The dealership said they "had never seen this before". They also said bmw had issued no bulletins to address the bolts. Every independent bmw facility I interviewed in portland was well aware of the issue and already doing engine rebuilds for their customers. I think this is gross negligence on bmw's part for not acknowledging the issue and dealing with it. I also think the dealer is guilty of clearing the fault without checking further. The bid on my work is $10,000 (two valve heads and a vanos system plus 50 hours of labor). This is an estimate until they pull the engine apart more. Online you can see on you tube my issue by watching this video. On all the forums there are threads to see the issue. You can see this by a google search of "bmw camshaft bolt shearing" http://www.Youtube.Com/watch?V=r6rdvbhscfg bottom line is if the bolts are not replaced eventually they will shear off and cause catastrophic engine damage. The faster the speed of the car the worse the damage. The problem is appearing it seems after 30k and for many including me between 60-90k. *Tr
