1998 BMW 740iL Problems

Engine -- Verified

Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.

Engine -- Verified

Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.

Suspension & Steering -- Verified

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

Suspension & Steering -- Verified

The rear lower ball joints may wear causing alignment and tire wear issues as a result of the excessive play in these joints. Our technicians tell us a 4wheel alignment should be performed after ball joint replacement.

Suspension & Steering -- Verified

The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps.

Thank U "hemicuda". Sounds like it would be pretty expensive to add a Turbo Charger with all the piston work that may be involved. Perhaps there's another way to reach 160MPH without...

Pretty good with Mech Tools, call it stress relief. I'd like to do some of the work on the car myself. That being said how much of this car could I work on before I cause serious damage :-).

1998 BMW 740iL Reviews

I love this car. Bought it from an owner more than a year ago by just test drive on freeway and I did not check anything. Fortunately, everything works. Just had to replace cats 3 months ago. Found after market and all cost just over $ 400. Very smooth, very fast acceleration. Just close the windows, turn on aircon and drive it on the freeway,I feel like I am a president.

My 1998bmw740il kills at idle after being driven for about 15 minutes. Starts back up. Runs great on the open road.The crankshaft engine sensor & thermostat sensor have both been replaced. Also the mass air flow sensor.What could be the problem?

Look,BMW has mastered the art of deception with the price of repairs.This is one of the most amazing cars on the road.You have to love driving more than life to appreciate what this machine is capable of......for example,Santa Monica pier to the Antelope valley in 33 mins.Yes 33 mins.top speed 167 MPH.They say the top speed is 145.The price.....look at it like this,I pretty much completely rebuilt mine for under $20,000.Ya sounds like alot but....I have a $75,000 car for a quarter of the price!!!!!!!!.YUP im the guy you seen on any so cal freeway in a black 740 IL going extremely to fast,sorry if i scared you.Catch me if you can.

I bought my car in late december of 2010. The previous owner drove 62,000 miles over the life of the car. The car was well maintained and driven by his wife. The car looks like it was never driven inside and out. I had the car looked at and did the car fax to check out the service records. I paid 12,500 for the car I have since spent 15,000 on new valves and head gaskets along with a long list of other issues that are more maintence issues and repairs that you would exspect with a 12 year old car. The good news is that the car does drive great and it is solid at this point. The previous owner never drove out of the city in florida and never went over 40 mph. I will pursue the dealership to cover the valves but as for now I have a great ride.
