If the transmission is slipping you may simply have a low fluid level. I would recommend checking the fluid level as the first step. If the fluid level is low have the system topped off and see if anything changes....
Usually power steering systems have a pressure hose that goes from the pump to the rack and pinion there is a return hose that goes from the rack and pinion to the reservoir and then there is a feed hose...
Hello - first task is to extract the problem code(s). There is a problem with the the engine/transmission setting the "Check Engine" (the wrench symbol), but only the codes will guide you to what specific problem needs attention. Given the...
hi. If you have a hose that has failed, then that would have caused a serious loss of coolant. This will definitely cause the engine to overheat. The hose needs to be replaced so that the engine can be checked...
Hello. Your vehicle has sensors that are installed into certain brake pads which alerts the driver when the brake pads are worn down to a certain point. These sensors need to be replaced whenever the brakes are done. They are...
It is hard to say if the A/C blower stuck on and the dash malfunction/engine shutdown are related but they are both a consequence of electrical problems. The stuck-on blower is easy to diagnose as all you need do is...
The E 30 can be a great driving car, but at 20 years old, It can have just about anything wrong. The self-diagnostics on the car are not very sophisticated, so you will have to do a systematic diagnosis. Making...
As you may have noticed, when the vehicle is in "ECO" mode, there is a significant reduction in power that is intentionally done to reduce emissions into the environment. You can try turning this off and you should notice a...
Any kind of water loss is usually not good. You cars performance completely depends on the cooling system. Your vehicle gets too hot, and the engine is destroyed. Do not run the vehicle out of coolant. There is not enough...
Hello. There are many components that can fail and cause an internal engine noise. On your car the most common is either a failure in the camshaft, this would cause a loud ticking, or a rod bearing which would cause...
There is a cooling fan relay fuse in the fuse box that controls the relay switch. This can sometimes fail which will cause the relay to work intermittently causing the fans to also work intermittently. I would recommend checking and...
This may be related to a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at...
Hey there, thanks for writing in about your 2007 Mercedes Benz E550. The car alarm in many of the later model Mercedes vehicles has it's own set of small batteries. When these batteries go bad, they will automatically set off the...
The manifolds on this engine warp and would need to be replaced to stop the leak. The manifold studs would also need to be replaced with the newer stainless steel type of studs and nuts. I agree with the muffler...
It sounds like you may have a transmission issue. The throttle position sensor plays a part in knowing if the transmission needs to downshift, but if you have a sticking shift valve, or a pressure control valve issue, that could...
Try using the factory plugs first and use them until you get all the modifications done. Then keep checking the plugs every month to see how they are burning to see if you need a hotter plug or a colder...
The speedometer is electronically controlled. Typically, there is a mini stepper (positioning) motor mounted on the instrument cluster PCB and it receives a signal from a speed sensor within the transmission. A wiring harness interconnects these components. The speed sensor...
Engine vibration at idle is due to either faulty motor mounts or an engine management fault (ignition, fuel, air induction, etc. but also including uneven cylinder compression and mechanical issues) or perhaps a combination of the two. The root cause(s)...
This may be a sign of a dirty or failing mass air flow sensor. The mass air flow sensor is a unit in the intake system that monitors air intake as it is mixed with fuel prior to being injected...
This can be caused by an internal leaking seal or valve body inside the transmission. You should have the transmission tested for proper pressures and failure codes for a defective shift solenoids.
