2008 Bmw M5 problems
The BMW M5 is a high-performance variant of the BMW 5 Series marketed under the BMW M sub-brand. It is considered an iconic vehicle in the sports sedan category. The M5 has always been produced in the sedan (saloon) body style, but in some countries the M5 has also been available as a wagon (estate) from 1992 to 1995, from 2006 to 2010, and since 2024.
The first M5 model was hand-built in 1985 on the E28 535i chassis with a modified engine from the M1 that made it the fastest production sedan at the time. M5 models have been produced for every generation of the 5 Series since 1985.
E28 M5 (1984–1988)
The first BMW M5, based on the E28 5 Series, was manufactured from October 1984 to June 1988. It made its debut at the Amsterdam Motor Show in February 1985. It was based on the 535i chassis with various mechanical changes, most notably the M88/3 engine (shared with the E24 M635CSi grand tourer coupé) which was an updated version of the engine used in the M1 sports car. At its launch, the E28 M5 was the fastest production sedan in the world.
The official markets for the E28 M5 were Europe, Great Britain, the United States, Canada, and South Africa. The European and South African cars used the M88/3 engine which has a power output of 210 kW (286 PS; 282 hp).
Cars sold in the United States and Canada used a detuned version of the M88/3 called the S38B35, which was equipped with a catalytic converter and has a power output of 191 kW (256 hp). Due to an extended production run that exceeded BMW's original forecast of production volumes, a class action lawsuit was launched by owners in the United States. The results of this class action was that owners were given a voucher for US$4,000 in 1993. Production of North American specification M5 commenced in November 1986 and ended in November 1987.
Aside from 96 cars which were assembled in kit form at BMW's Plant in Rosslyn, South Africa, all cars were assembled by hand in Germany. Assembly took place at BMW Motorsport's plant in Preussenstrasse in Munich prior to the 1986 factory summer vacation. Thereafter, the M5 production was moved to Daimlerstrasse in Garching where the remainder were built. Production of the M5 continued until November 1988, almost a year after BMW had ceased production of regular E28 models. With a total production of 2,241 units, the E28 M5 remains among the rarest regular production BMW Motorsport cars – after the M1 (456 units), M5 (E34) Touring (891 units) and the 850CSi (1,510 units).

Common 2008 Bmw M5 problems
Based on the sources provided, here are the common problems with the BMW M5 2008 based on complaints from owners:
- VANOS Problems: Another common problem reported by owners is related to VANOS, which is BMW's variable valve timing system. Issues with VANOS can affect engine performance and reliability, requiring attention to prevent further damage.
- Differential Concerns: Owners have highlighted differential issues with the BMW M5 2008. This problem can manifest as noise or performance issues and may necessitate repairs or replacements to ensure proper functioning.
- CCC Failure: The iDrive system, known as CCC (Car Communication Computer), can experience failures in the BMW M5 2008. This can lead to issues with the infotainment system and other electronic functions in the vehicle.
- EDC Damper Wear: The Electronic Damper Control (EDC) system in the BMW M5 2008 is prone to wear over time, especially after reaching a certain mileage. Upgrading to aftermarket dampers like Bilstein B16 Damptronics is recommended to address this issue.
- SMG Pump: For models equipped with the SMG transmission, owners have reported problems with the SMG pump. This component can fail over time, leading to transmission issues that require costly repairs.
- Steering Sensor Fault: A common fault shared with the 5-series model is related to the steering sensor. Failure of the optical sensor necessitates its replacement to ensure proper functioning of the steering system.
- Transmission Electric Motor Failure: The SMG transmissions in some BMW M5 2008 models could suffer from electric motor failures. This issue requires attention and may be addressed through technical service bulletins.
These common problems highlight the importance of thorough maintenance and potential upgrades to address known issues with the BMW M5 2008 model. Regular inspections and proactive measures can help owners mitigate these concerns and ensure the longevity and performance of their vehicles.
Is the BMW M5 reliable?
Reliability rating
The BMW 5 Series range (including the M5) has a poor reliability score of 47% as of January 2024, according to workshop and warranty data provided by our commercial partner, MotorEasy. This covers both the current (2017 onwards) model as well as earlier generations of 5 Series.
What is the problem with the E60 M5?
Rod Bearing Issues
The rod bearing issue is such a nightmare with the S85 that it's sometimes the only reason people turn away from buying a BMW E60 M5. While a rod bearing failure can occur on any car, the likelihood of it happening on this M5 was unnaturally high.
What is the best year for a BMW M5?
E39 M5 (1998-2003)
M-division aficionados might find it impossible to agree on one particular version as being the outright best, but we'd wager almost all of them would say that the E39 was one of the greatest.
How long does a BMW M5 engine last?
I have 75,000 miles on my M5 and plan on keeping it well past 100,000 miles. Just keep up on regular maintenance service intervals and keep an eye on your oil consumption (if you have any) and you should be good. There are other members on here who have over 100,000 miles on their M5 and they're still going strong.

Over time, increased resistance at the taillight electrical contact points may cause damage to the ground terminal and housing of the connector resulting in an intermittent or permanent loss of functionality of one or more rear lamp functions (tail, brake, turn-signal, reverse).
- Consequence: Intermittent light operation reduces the ability to warn other motorists of the driver's intentions, increasing the risk of a crash.
- Remedy: BMW will notify owners, and dealers will replace the rear lamp bulb carriers free of charge. Owners may contact BMW customer relations at 1-800-525-7417 or email BMW at [email protected].
- Manufacturer: BMW OF NORTH AMERICA, LLC

I've owned an M-5 for about 6 months now and I must say, I cannot go back to an 'ordinary' BMW. The car is the most fun thing one can do with shoes on! It may drive a bit jerky at slow speeds, but let's be honest, it wasn't meant to go at slow speeds! On a serious note, the SMG takes a little bit of getting used to, but I find the manual to be a lot smoother. The only downside is the gas mileage, which is around 14.6-15 mpg. However, it makes a statement and turns heads wherever it goes. I absolutely love the growl it makes when I downshift. For all the folks who want an M experience, once you drive one, you cannot go back!

Took delivery in Germany (ED program - look into it!) and received it back in the US one month later. What a fabulous car! Whether driving at sane speeds (50-80 mph) or Autobahn speeds (150+ mph), the car is very predictable and gives excellent feedback. It doesn't feel like a 4000+ lb car through the twisties. The SMG is a great system, once you get used to it.
Emmitt Cruickshank 2024-11-01
I'm so glad to hear that you love this car!
Kameron Abshire 2024-10-29
I had a 545, and this is nothing like it. Way better gadgets. The improved navigation and heads up display are great, the seats are much better, and the acceleration is fantastic. The transmission is my favorite. This car is not for the faint-hearted driver.
Josue Hyatt 2024-10-12
This car is truly amazing! It can be used as a family sedan to take your loved ones around town or as a race car. I recently traded in my 600hp Subaru STi for this car and I have absolutely no regrets. It turns heads wherever I go and sounds fantastic! The interior design is very nice, although the iDrive can be a bit confusing at first. Take about 20 minutes to experiment with it and you'll get the hang of it. And if you think this car can't get any better, just press the M button and everything becomes even more amazing. The throttle and steering response are instantaneous and the sound of the exhaust is simply beautiful - a smooth yet sporty sound that cannot be replicated. It's a 4-door car that can even be taken to the track!
