Dashboard Experiencing Excessive Warnings

[MBcarOWNER]

The car is a 2002 CLK240.

There is a new malfunction in my 2006 SL350.

The dashboard sometimes experiences erratic behaviour, displaying a multitude of warning warnings.

Malfunction in the restraint system
The SRS system sometimes experiences a temporary loss of functionality, causing the rev counter, speedometer, and fuel gauge to momentarily drop to zero before returning to normal.
Spotlights flicker and headlights
Indicator for rollover protection system Indicator for low battery level Indicator to prompt a visit to the workshop
The command becomes uncontrollable.
Heater controls are modified.

There seems to be a significant amount of historical discussion on these forums on the issue at hand, which is related to the census. If I understand correctly, the consensus is that the problem lies with a defective Electronic Ignition Module (EIS or EIM?).

Is that view still prevailing? Can anybody contribute to this?

If I replace the EIS / EIM, do I need to alter the keys, or is the identification process managed in a different manner?

Thank you.

Have you conducted a battery test? Occasionally, a deteriorating battery might result in a variety of peculiar alerts.

The battery is commendable.

Additionally, it is not advisable to disclose your postcode on the forum.

Conducting a battery test would be my first course of action, since it is also the most straightforward and cost-effective solution.

Another endorsement for the battery as the probable cause....

However, if you would want an alternative recommendation, where do you store it while it is not being used?

Indeed, we all have suspicions that the battery, and maybe the battery connections, are the primary cause.

After properly charging the device and having someone read and reset the problem messages, it is necessary to address other concerns such as controllers and wiring. To do so, it is necessary to engage the services of an automotive electrician or consult with a specialised Mercedes-Benz technician in your area.

Contemporary sensors are exceptional. They provide many erroneous error messages, some of which may even be accurate.

Regarding the backdrop colour, is this automobile often utilised? How often do you drive, a few times each week, or about 5,000 miles per year? Alternatively, similar to many others, is it a vehicle that has been stored in a garage and not used over the winter?

Ensure you inspect the battery. It would be advantageous if you had the ability to interpret fault codes. My automobile had a malfunctioning Wheel Speed Sensor, resulting in many apparently unconnected alerts such as ABS, Engine Fault, and the roof not closing properly. This issue arose because the car was unable to determine its movement status.

[MBcarOWNER]

The vehicle is often parked outside on the driveway and is hardly used, usually just for 2 to 3 times a week, mostly for short trips.

I had the issues resolved by my nearby autonomous Mercedes-Benz expert (who also suspects a battery issue).

I have just installed a new high-quality AGM service battery. Its performance will be observed and evaluated.

Thank you for the feedback received so far.

[MBcarOWNER]

I will provide an objective update, since I am optimistic that someone more intelligent than myself will be able to discern the logical reasoning behind it.

Regrettably, the newly acquired AGM battery failed to meet the expected result. Currently, I own a fresh Consumer/ Systems battery as well as a very new starting battery, both of which are completely charged. Despite this, I am nevertheless able to observe the whole dashboard display.

As anticipated, I have diligently searched in every possible location for recommendations.

I encountered an unconventional remedy that included squirting contact cleaner into the ignition keyhole in the evening, and then using a hair dryer to blow air into the key slot the following morning.

Indeed, I too found it absurd - particularly the suggestion of using contact cleanser. However, in my state of desperation, I pondered if there was any logical reasoning behind the idea of warm air.

The next day, I positioned a fan heater on the driver's seat and directed its airflow towards the bottom section of the dashboard, namely where the ignition key is situated, for almost two hours. The day was characterised by low temperatures and very low humidity.

Subsequently, I drove the vehicle for more than thirty minutes without encountering any problems whatsoever, despite the fact that the dashboard often activates within five minutes of starting a drive.

On the next day, I had to go on a journey that was characterised by a somewhat moderate temperature and precipitation. Shortly after starting the automobile, the dashboard once again exhibited erratic behaviour.

I have pondered this matter - was the fan heater technique only a fortuitous occurrence? If not, what is the significance or implication?

This morning, the weather was very chilly and dry. In order to replicate the experiment, I used the fan heater.

I have just returned from a drive lasting over forty minutes, during which the dashboard functioned well.

There seems to be a correlation between the activation of warm or hot air on the dashboard prior to starting the automobile and the occurrence of erratic flashing lights.

However, what is the underlying cause behind it?

Indeed, I am aware that it may seem irrational, but I am very certain that I could replicate it consistently and have same outcomes.

Do you have any suggestions or thoughts?
