Inspect the wiring of the fan controller at the controller side to see whether there is any corrosion present.

There is apparent sparking occurring on at least 3 cylinders of the left hand bank. I have not attempted to start the engine several times, but I need assistance from another person to turn the key while I inspect both sides of the engine. I will endeavour to get video footage of my current observations, but unfortunately, this will not be possible until a few weeks from now, since I will be on vacation starting tomorrow. It is a fly-by-wire (FBW) system, but I also tested it when cranking and there was no wide open throttle (WOT) occurrence at that time. It might be a misleading clue, so I will not prioritise it. If I were able to briefly operate it by injecting gasoline directly into the intake ports using a syringe, that would be a notable achievement. However, the engine just produces backfires instead. Although I acknowledge that my technique is not particularly scientific, I believed it was worth attempting.

The tank was emptied before to storage and only high-quality, newly-purchased gasoline was utilised.

Prior to being stored, the automobile was functioning well. I apologise for any misunderstanding about the chain. Although it seems to be in excellent condition, it is undoubtedly the original. I possess absolute certainty that I am the only one who has conducted an examination of the engine, including the removal of injectors and rail, intake manifold, throttle actuator, rocker covers, and other components. Upon inspecting the engine last night, I saw that with the intake manifold removed and the Throttle actuator attached, the throttle does not open beyond around 15% even when the accelerator is completely pushed. The mechanism is not obstructed and can be manually moved without any difficulty. However, it seems to be malfunctioning, indicating a need to inspect the signal being sent to it. Additionally, testing the throttle position sensor is advisable, despite the absence of any error messages on the STAR system.

The camshaft and crankshaft timing are perfectly aligned, ensuring that there are no issues with the valves coming into contact with the pistons or any compression difficulties. The electronic timing is significantly inaccurate, causing the spark to be delivered to the cylinders at an incorrect moment. I will thoroughly investigate the wiring to see if there are any issues and conduct a continuity test on all components. The vehicle was stored, but, there is no indication of any rodent-related damage present, even under the dashboard.

I own a STAR diagnostic tool, which is now indicating the absence of any engine codes. I have attempted to use three different crank sensors and have tested each one on another m113, all of which functioned well. I have even removed the CPS connector to see whether STAR detects it, and it does, so I cannot identify that as the problem. As you said, the essential components for starting an engine are spark, gasoline, air, and proper compression. However, in the case of my automobile, if I can see sparks from the intake ports, it indicates that the timing is incorrect. I will capture a video and upload it for you to see the same visual experience as mine. Thank you for your contribution. 👍

The vehicle has been stationary for a few years and is now unresponsive when attempting to start it. Three of the original injectors were experiencing leakage, therefore I have replaced all of them with new Bosch injectors. I have also performed the same action with all of the typical suspects. The engine emits intermittent bursts of exhaust and ignition failure, but fails to operate. I have inspected the exhaust system for any obstructions, and it seems to be in proper working condition. I own a STAR diagnostic tool which indicates that there are no error codes for the engine, and the drive access is now displaying "start enabled". There are no apparent problems with the wiring, such as damage caused by rodents or water. However, I have not yet tested the continuity of all the cables and connections of the electronic control unit (ECU). I am enquiring if the electronic control unit (ECU) has been compromised in any way. Thank you once again for your valuable contribution. 👍

Thank you and I completely agree. The coil LT connectors/loom can only be installed in one certain orientation on the m113, hence it is unlikely that they may have been the origin of the issue. Given the precise static time, it is perplexing how the coils manage to transmit their electrical charge to the spark plugs while the intake valves are open. I am attempting to get a pin out diagram for the electronic control unit (ECU) in order to do a comprehensive assessment of the wiring for any potential problems. I had previously performed a comparable task on my 94 SL600 by completely rewiring the engine, however it seems that the task at hand is somewhat easy to do. Perhaps I am searching in the incorrect locations. 😁👍

Greetings, gentlemen. I am experiencing a failure to start with my 1998 SL500, which has 65,000 miles on it. I would appreciate any insights or suggestions you may have on this issue. First, let's provide some contextual information on the issue. The engine is functioning well, as shown by the ignition system producing a strong spark, the fuel pressure measuring at 55psi, and the compression levels of all cylinders averaging at 185psi. The IRRC is functioning well and DAS2b is shown as being in a start-enabled state on STAR. The Electronic Control Unit (ECU) is indicating that it is functioning properly and there are no error codes detected. The automobile is equipped with recently installed components including a new crank position sensor, cam sensor, fuel pump relay, spark plugs, fuel injectors, fuel pump, and filter. All components are either genuine Mercedes Original Equipment Manufacturer (OEM) parts or Bosch parts. Thorough inspection of the coil packs on my 2004 M112 350sl revealed no problems. Since the automobile did not come equipped with an Aux air pump from the manufacturer, I can safely rule it out as a potential cause. I have conducted an examination to identify any potential hoover leaks, and I can confirm that none are currently detected. The car's backfiring has caused significant damage to the original intake manifold, resulting in its physical explosion due to the ignition of unburnt gasoline inside it. After removing the manifold, I can easily see the presence of a spark while revving the engine and examining the intake port. The cam timing has been verified and found to be precisely set at 40 degrees, in accordance with the specified specifications, while using the locking tool. The engine has remained intact till I inspected the timing in order to rule out any inept craftsmanship. The timing chain seems to be in pristine condition and is properly tensioned. The crank sensor trigger ring seems to be in excellent condition based on my observation. I am having difficulty understanding how to visually see a discernible spark via the intake valves while the crank is in motion. How can the timing be so inaccurate? Is it probable that the problem is related to the ECU? Does anybody have any suggestions for doing ECU testing? Sorry for the long message, but I am having difficulty with this issue. Greetings

If you want to determine the optimal shift locations with precision, the most straightforward approach would be activating Dynamic Mode in your vehicle, selecting the Automatic gearbox setting, accelerating vigorously, and observing the computer-controlled shifts. The computer is programmed to optimise the optimal shift spots in each gear during Wide Open Throttle (WOT).

Have you explored this website? It has several X owners and a wealth of valuable information.

The price for my previous F31 330d xDrive was £30 per litre. I chose to go with BMW since there were too many factors to consider.

Thank you, NarrativePsych. I am now doing a local search for a few Mercedes technicians. Additionally, there are several breaker 201s that are exposed to the intense heat of the sun, which suggests that the inside condition is likely to be poor. If you happen to encounter one, please inform me, Will. There is no need for you to waste your time on this matter. At any given time.

That was my alternative consideration in the event that nothing arises.

I need to remove it next week and take measurements. I will provide you with updates.

I was also curious about it!

Greetings, everybody! I am searching for the wood trim that is included in the attachment, specifically for a 1991 W201 vehicle. Please inform me if someone has one, or if you are aware of anybody who may own one. Thank you in advance

The automobile is impressive, but I lack knowledge about it. What is the meaning or significance of "v8"?

I have a replacement on its way. Can I just change them over and consider the task complete? I would want to learn about the leak off test since I have never performed one before.

Upon obtaining the vehicle identification number (VIN), I have determined that the engine in question is the N52 model.

There is a problem with the idle of my father-in-law's automobile, which causes it to run roughly. However, once the car is in motion, it appears to function well until it slows down or comes to a stop. The trouble code 0029ce indicates a combustion misfire in cylinder 2. I interchanged the positions of coil 1 and 2, but, I still encountered a fault with coil 2. Additionally, I exchanged the plugs but the issue persisted. Has anybody else had a similar problem or has any relevant information?

Occasionally, I get a notification upon starting that states "blind spot system inhibited". I disregard it as the system seems to be functioning well.
