I apologise if this is the situation. I need guidance regarding the presence of odour in the cabin despite the exhaust system being in its original condition.

Fortunately, for automotive aficionados, the regulations in my locality are merely theoretical.

In all honesty, I likely ought to. However, in actuality, the odour was present since the inception of the stock system. To clarify, the "homebuilt system" is constructed by my friend, a skilled exhaust fabricator. I believe I should commence with a smoke test.

I possess a first edition Proceed GT 12/500, which I thoroughly enjoy modifying and driving; nonetheless, I have encountered this issue since the day of purchase. The stock exhaust of the GT includes a primary catted downpipe positioned post-turbo and an additional one located immediately thereafter (which I purchased without). During a test drive, I detected an odour during heavy acceleration with the windows down, but I dismissed it. Fast forward one to two years of ownership, I resolved to enhance power and sound by constructing a custom catless downpipe. Following the installation of the downpipe and subsequent tuning, the exhaust fumes are incessant and overwhelming when the windows are lowered. Even with the windows closed, I perceive that they still infiltrate the cabin. Nonetheless, I am uncertain about the issue, given the odour was present prior to my removal of the catalytic converter. I attempted to extend the tailpipes, but there was no alteration. Do you have any recommendations?

I have successfully resolved it! The block connector connections on the aesthetically pleasing, although subpar quality, aftermarket headlamp components had begun to deteriorate. Several tips of the pins were really disintegrating. I connected the block and, after identifying several faulty lights, discovered that everything began functioning properly. The extensive hours of meticulous re-wiring yielded commendable results, undoubtedly! Aside from the expense of a batch of Scotch connectors, it was complimentary (quite atypical for my Z4)! Joyful days!

There is no evidence of combustion or thermal damage around the cluster connection or the terminal connector of the wire. Are there further earth connection points to verify, and if so, what are their locations?

I disconnected the ground tracks in the light cluster and connected a line directly from the battery, thus the ground should be adequate.

That is a compelling concept. I suppose there is no harm in attempting.

Greetings, everyone. I am now addressing yet another issue with my 2003 Z4 2.5L E85, but progress is being made. When I signal left, everything functions correctly; however, when I signal right, the ticking noise accelerates, and the rear brake light flashes instead of the indicator. How bizarre! When I activate the hazard lights, they operate as anticipated. I believe all bulbs are functional, with the exception of the side repeater, which I have not checked for replacement; nonetheless, I do not anticipate it being defective. I established a temporary ground connection to the light cluster at the rear, as the faulty ground at the cluster was a convenient starting place; nonetheless, it yielded no improvement. Any guidance would be greatly appreciated. I have encountered mentions of 'rear tail light earth' in many threads here, but I have been unable to locate any specific information

The original poster replaced the primary battery three months ago. It continues to discharge, necessitating an investigation into the cause.

Greetings to all I possess a 2022 C Class Estate and extensively utilise the Mercedes Me application on my iPhone. It consistently functions effectively and provides information regarding the vehicle's status, security condition, location, and more. Recently, the application has ceased functioning, albeit sporadically. For instance, it inaccurately displays the car's location, indicating a position I occupied an hour prior. It indicates that the automobile is unlocked when it is not. It does not respond to the app's request to lock the doors, open the windows, etc. It appears that a Mercedes server may be malfunctioning or operating at a significantly reduced speed. The issue cannot be attributed to network connection problems, as the vehicle has consistently functioned well in the same locations for several years. Then a few hours later - while the car is in the same location everything starts worming again. It is sporadic yet notably common in recent days. Is anyone else observing this behaviour, please? Or is it a recognised issue that I have not picked up on? I observed that an individual on Twitter (X) reported similar behaviour regarding his vehicle a few days prior. I am enquiring whether there exists a global issue with the system. Do you have any suggestions? Warm regards

Thank you all for the information. New Duracell batteries have been installed in both keys, and extra ones are also in the vehicle.Thank to everybody.

While shopping today, I returned to my vehicle and pressed the start button, only to receive a message indicating that no key was detected. After several attempts, a new message prompted me to press the start button with the key fob. I complied, and the car started. Upon arriving home, I checked to see if the issue persisted, but everything returned to normal. I also verified that the key fob battery was fully charged at 3.1V. Any suggestions?
