About BMW Z4
As one of the most intriguing and oldest luxury sports car available, BMW Z4 has been built by a famous German manufacturing company, Bayerische Motren Werke AG, more known under its abbreviation BMW, since 2002 as a roadster and sports car. Originally introduced as the third model in the BMW Z Series as the successor to the Z3, Z4 is now BMW's only two-seat sports car. Competing against the Porsche Boxster, Mercedes-Benz SLK-Class and Audi TT, Z4 does well in motorsport and won the Silverstone Britcar 24-Hour race. Now, Z4 is in its second generation.
The first-generation BMW Z4 (E85/E86) was produced from September 2002 to August 2008 and made its debut at the 2002 Paris Auto Show. It went on sale in North America in November 2008 as a 2009 model and was offered in two body styles, 2-door roadster (E85) and 2-door coupe (E86). Z4 came in 2.0i and 3.0i trim levels as roadster and 3.0i and 3.0si as coupe. During this generation, BMW Z4 was powered by 2.5 L I6 rated at 184 hp, 3.0 L I6 generating 225 hp, 215hp and 255 hp. And these engines sent power through 5-speed, 6-speed manual and automatic as well as 6-speed sequential manual gearbox (SMG) transmissions. Current Z4 (E89) was unveiled at the 2009 North American International Auto Show and went on sale in May 2009. It now comes in sDrive28i, sDrive35i and sDrive35is as a 2-door retractable hardtop roadster. Now, Z4 gets power from 2.0 L I4 rated at 240 hp and 260 pound-feet of torque, 3.0 L I6 good for 300 horsepower and 300 lb-ft of torque while 35is's 3.0 L I6 could produce 335 hp and 332 lb-ft of torque. And these engines are mated to 6-speed manual, 8-speed automatic, and 7-speed dual-clutch automated manual transmissions (DCT).
BMW Z4 Common Problems & Maintenance Tips
Being an impressive and highly refined sport touring car with a surprisingly roomy interior and decent trunk space as long as the retractable roof is raised, BMW Z4 could be seen as a perfect choice for affordable well-rounded sports cars. But a wise Z4 driver will always be prepared for these common problems on it in advance:
First, according to the reliable car repair statistics site repairpal.com, engine failure deteriorated by cooling system failure ranks first among all other issues on BMW Z4. Most Z4 drivers know that engine failure is bad enough, but once the cooling system also fails and the engine keeps staying at a high operation temperature, then you will know how worse the situation is. You are supposed to diagnose and solve them as soon as possible. Generally speaking, before these issues display themselves completely, you can notice if there are strange sounds from the engine; if there are leaking oil and coolant on the ground; if the engine starts to run roughly, misfires, stalls and even suffers from starting issues. Before the vehicle breaks down completely, the vehicle will also have a big decrease in power, acceleration and fuel economy. Once the Check Engine Light and Low Coolant Light come on together, you are advised to set out to inspect the Z4 water pump, coolant reservoir, radiator, cooling hose, oil filter, air filter, spark plug, oxygen sensor and fuel pump immediately.
Second, suspension failure on BMW Z4 is also very troublesome to deal with, especially for those who do not have much knowledge about working principle of automobiles. In fact, many Z4 drivers do not have a correct understanding about this issue so that it is often too late when it appears. Apart from the unsteady and uncomfortable driving experience, it could bring, suspension failure is often also the culprit of fatal accidents caused by drivers' poor driving skills. Therefore, these symptoms such as clunking or grinding noises coming from underneath the vehicle, intense car vibration, unintentional steering, loose steering wheel and poor handling should be attributed to the Z4 wheel bearing, ball joints, shock absorber, sway bar bushing, control arm bushing, steering knuckle and drive shaft.
However, you should also attach enough importance to perform routine maintenance on vulnerable auto parts on your BMW Z4.
