Is it expensive to own? Given that the average E4. To some, a car that starts and runs and doesn't break down frequently would be considered reliable. To others, a . The E4. If you want or expect a car that will get you where you need to go (provided it is properly maintained), an E4. If you want a car that you can abuse or neglect, or one that will be absolutely free of any sort of minor nuisance or defect, look elsewhere.

Virtually all of the model's common problems are now well documented, and most are actually fairly easy to diagnose and repair. ALL 3. 23/3. 28 sedan/coupes). Convertibles and Wagons of all years have least reports of failure.

For all models, it is important to verify subframe and differential bushings are in good shape so there is minimal play in heavy drivetrain components which could further stress the subframe mounting area. The E4. 6 is not an exotic car per se, and does not generally require any special service techniques beyond any other typical import car, though dealerships and many third party shops will attempt to bill you as though it is. Without question, you will save a significant sum of money by performing your own simple repairs and routine maintenance; meanwhile, paying dealership/shop prices for window regulator repairs and blower resistor pack replacements will make it difficult to justify the cost of ownership. If you intend to have a third party perform all work, you might realistically expect to spend 2- 3x this amount. If you are going to buy a used E4. Luckily, the E4. 6 had free maintenance until 3. BMW dealers. Any dealer should be able to provide the service history with just the last seven digits of the VIN.

This is an extremely common failure and a clear weakspot on the E4. Sedans. Some owners had success asking BMW NA to cover all or a portion of the cost for this design defect even when the vehicle was out of warranty. As stated in BMW's TSB, . CAUSE: Minor corrosion at the 8- pin rear lamp connector creates high resistance causing damage to the connector housing. CORRECTION: Repair the damaged wire(s) and replace damaged connector housing. Install additional ground wires to both left and right rear lamps.

Symptoms include a . While BMW has a TSB for this problem, many have occurred out of warranty leading to arguments with the dealer (automotive lighting standards are Federally legislated, yet BMW refuses to repair this design defect once the cars are out of warranty). This problem was not limited to US market as you can read here. When this occurs all coolant is lost within seconds and the engine will overheat instantly (remember, these cars have only a total of ~2 gallons of coolant). A much better water pump than the stock/OEM unit is available from EMP Steward, but it's pricey ($2.

Other items on the cooling system that should be considered maintenance items since they will likely/eventually fail are the plastic/electric thermostat and the coolant reservoir. Therefore, preventative cooling system maintenance replacing these items every 6.

This was already the case with the M5. E3. 6, but it's much easier to repair on the E4.

M5. 4 engines since the timing chains do not have to be removed. This defect is mostly related to the Buna o- rings in the unit's control pistons which due to heat induced hardening allow excessive oil bypass, thus leading to less accurate control of camshaft timing. Fluctuating idle or stalling can also be signs of this problem. Depending on maintenance this can already occur at 5. K miles. If this defect occurs, there is a noticeable rattle in the engine from the VANOS unit, often around 2,0.

Repair is actually relatively easy and a true DIY for someone who has basic skills. Replacing the Buna o- rings with higher quality Viton rings in the VANOS unit will fix the issue. Better yet Dr. Vanos sells complete rebuild and blue printed VANOS units that are even better than new OEM BMW units and Beisan Systems sells the above mentioned Viton seal/o- ring DIY kits.

Cam sensors (intake and exhaust) on the VANOS unit are also prone to fail and as small as they are, they are expensive ($1. The exhaust sensor is usually the first to fail and that occurs often right around 1. K miles. It has been proven that ONLY OEM BMW sensors should be installed during repair since all aftermarket units are not that compatible and of lower quality. VANOS units on ZHP cars are especially failure prone for undetermined reasons. Common opinion is that this is related to the more aggressive camshaft profiles. Most often the two rear mounting points below the trunk floor are affected. This occurs more often (but not exclusive to) on the early E4.

BMW later improved the subframe mounting points in the trunk floor of the car and in later E4. This problem seems to be so frequent in early E4. IS AN ABSOLUTE MUST! Repairs are very expensive and difficult since the rear axle and subfram have to be removed and the unibody frame and mounting points have to be welded. Recurring stress cracking often occurs even after a repair has been made. You can find more information as well as what it looks like in these threads: Thread 1.
