I sincerely apologise if my post caused offence. Based on my experiences over the years, it appears that very few individuals are willing to contribute or assist others. When such assistance does occur, it is undoubtedly invaluable, yet it seems challenging to connect with someone who possesses the necessary knowledge.

There must be someone available who can assist. Kindly or Is this forum as inactive as it appears?

My 2007 W639 Vito 111 CDI has begun experiencing fuel-related troubles. Exiting the conversation. The background is as follows: after performing repairs on an injector blow-by and the hold-down bolt threads, the car began to leak gasoline from its leak-off system. I suspected that I had been excessively forceful with the press-down clips on the plastic pipe fittings attached to the spigot pipes emerging from the side of the injector.I conducted a leak-off test and discovered that three of the injectors were defective, exhibiting excessive fuel leakage. Consequently, I acquired a whole set of replacement injectors, Honda copper washers, and new stretch hold-down bolts, and replaced them together with a brand new leak-off pipe system. after a run test drive i noticed it was leaking yet again but this time knowing full well the leak off was just a dribble and the leaking wouldnt start until at lease five mins of running ,i then purchased another pipe set believing it must of been a dud set i had previously got and fitted another new set ,another test run and another leak ensued so this time i thought it must be having trouble to leak back into the in-tank pumped supply line where it is plumbed into via an alloy y adapter ,having looked at it i considered it could either be a clogged filter (where the in tank pump brings the low pressure supply into) or maybe a locked up non return check valve which is in the new replaced leak off pipe so i checked the valve using air line and a peice of stiff wire all good replaced filter and test drive ,still leaking fuel out of the weakest point of the rubber leak off sections between the injectors , this tells me the pressure of the system where it is supposed to bleed into is far too high ? I assume that the return line to the tank may be obstructed. Could it be a defective pressure regulator valve in the common rail? Are there any technicians available to assist me in resolving this issue? I am perplexed; the vehicle starts and operates flawlessly. Could it be experiencing excessive pressure owing to a malfunctioning pressure control system? How does it control the pressure returning to the tank following its effective transit through the common rail? I am unable to locate anybody with the requisite experience and traditional diagnostic skills to identify this type of defect from the past.

Verify using your vehicle's VIN. Does the vendor not supply the VIN, or are there no local websites that offer the VIN along with the registration plate?

It is quite evident, indeed. Otherwise, there would be numerous shunts daily, as the majority of relatively new vehicles are equipped with Adaptive Cruise Control (ACC).

Presumably, you are referring to the scenario in which the Adaptive Cruise Control (ACC) detects a deceleration ahead and engages the brakes; otherwise, a rear-end collision with trailing vehicles would occur.

The dome-shaped plastic should simply detach. Ensure it is unobstructed and that the little arm behind the cover is not ajar.

A thorough cleaning may also be beneficial.

Allow your wife to operate the vehicle and get a superior option for yourself.

Did you acquire the vehicle with diminished power, or did you have the DPF and EGR systems reprogrammed, resulting in satisfactory performance thereafter?

Variations in tire tread depths exceeding a few millimeters between the front and rear tyres, as well as between tyres on the same axle, may lead to comparable troubles, since the transfer box is adversely affected by such discrepancies.
