What you are describing sounds like a faulty starter solenoid. A faulty starter solenoid will generally produce a clicking sound when turning the key. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity...

Hi, thanks for your question. I'd be happy to help. The diesel battery may be heavy duty compared to the petrol engine. The two batteries should be compared for size and height to be the same and the terminals should...

This could be a variety of potential issues related to lack of fuel delivery or spark. The tendency to shut down randomly and then start up again after sitting for a bit suggests potentially faulty coil packs which are known...

Hello. You may be facing more than one issue at the same time, due to all of these being related to a different system. One of the only components that can effect all of these systems is the ground connections....

Hello - except for the Mercedes factory Service Manual/DVDs, the usual sources of quality aftermarket service manuals (i.e. Bentley) are bare on this one. Haynes/Chiltons don't yet cover anything this new either, certainly not for S-class models. Your best bet...

Hello. Every warning light is accompanied with a definition which can be found in your owners manual. Once we determine which system is being affected, we can start from there. 5 miles ins't very far which leads me to believe...

Hi there. The issue seems to be the shifter interlock solenoid may be malfunctioning causing the steering wheel lock to not release or not engage. I suggest having the computer scanned for any codes that would be stored or pending...

Hi there, thanks for writing in. I have never experienced this exact issue before. First we should address the vacuum leak, which could cause the car to stall while idling, as well as being a potential cause of the oxygen...

A faulty or blown fuse in other electronically controlled systems can cause the IAC (idle air control) motor to malfunction, leading to a higher than normal engine idle speed. Other possible causes of a high idle include vacuum leaks, a...

Hey there. This is likely a sign of failing CV joints. All front-wheel drive cars have "constant velocity" joints or CV joints on both ends of the drive shafts. Inner CV joints connect the drive shafts to the transmission, while...

Hi Jessica. Thanks for contacting us tonight. If the lightning bolt light is red, this is typically an indication that the electronic throttle control is either damaged or has a blown electrical relay. Unfortunately, it could also mean that the...
