All Activity

Hello everyone, I previously discussed limp mode here some time back. A small mechanic inspected the car but was unable to identify any issues and expressed confusion. Instructed me to remove the interior fuse box, as moisture occasionally infiltrates and induces erratic malfunctions. I examined all fuses and relays, stored it in a warm location for a week, and subsequently replaced it. The fault code for glow plug number four was detected, prompting the replacement of all four glow plugs. Currently indicating the activation of glow plugs 1, 2, and 3. I will replace the glow plug harness and the glow plug control module. Any assistance would be greatly appreciated.

The configuration is consistent across most BMW models currently, making the task exceedingly difficult because to the large shaft and the multipoint pinion nut. I received a quotation for £350. I believe it pertained to my previous F11 few years ago.

I am unaware of your vehicle, but mine was subpar; there is a substantial nut.The BMW F82 M4 differential employs a substantial, single-use M39 nut with a 1.5mm thread pitch for the input flange (pinion shaft), necessitating specialised equipment and considerable power for removal and accurate torque application. Nuts are also related with the axle shaft seals (output seals). I indicated that the Loctite used was not factory-sourced; however, it must have been, as the vehicle had only 20,000 miles at the time of purchase. Regardless, they successfully removed it, but my differential emitted a whine upon reassembly. Consequently, they procured a new differential and installed it, resolving the issue. Naturally, I incurred no costs for the new differential or associated labour. Nevertheless, I remain uncertain about the differences between the M4 and standard vehicles, as the differential fins and similar components are larger and more robust. The initial leak was addressed, and servicing is required following the leak repair.I required a pinion seal from a BMW shop. The service cost was £88, while the repair for the leak was approximately £400. My vehicle exhibited discolouration followed by a weep, prompting me to cease driving until I could schedule an appointment.

The task should be very straightforward, provided the axle carrier does not obstruct the removal of the exhaust and propshaft. However, I am uncertain about the costs, as they can vary significantly; it is advisable to obtain multiple quotes.

I suspect the input seal from the propshaft is the issue. Are you aware of the simplicity of this repair and the estimated expense involved?

The urgency of the repair is contingent upon the extent of the leakage; if the staining is minimal, it may be addressed at a later time, but if the stained area is substantial, it is advisable to undertake the repair promptly. The movement of the drive shafts is the reason they have a finite lifespan.

There are three seals: one for the input from the propshaft and two for the left and right drive shafts. You will need to inspect to determine which one is leaking.

Greetings, I recently completed my MOT and received an advise indicating a minor leak from the rear differential seals. Is anyone aware of the root of this issue and its severity? The vehicle is a BMW F32 4 Series diesel with a 2.0-liter engine. Thank you.

I am experiencing a distinct problem with my automated main beam. When temperatures fall below zero, the default setting activates the main beam continuously, and the sole method to deactivate it is to turn off the lights entirely. Suboptimal! Fortunately, I reside in a region of the UK that does not frequently experience really low temperatures.

I appreciate the information; thank you for sharing.

That is customary; it is their expected duty. I possess a 2021 CX-30 Preferred equipped with automated headlights and auto high beams.

Thank you! It was indeed drizzling, which may have contributed to it.

The automatic system may have been temporarily disabled, which occasionally occurs in my vehicle as well. This can be due to debris, adverse weather conditions, etc., causing the system to be uncertain about the operation of the lights (I possess adaptive headlights). I consulted my mechanic, and this phenomenon is considered normal; I have only observed it during rain and fog.

I am uncertain whether I overlooked this previously or if it is a recent occurrence. I have configured my headlights to automatic for activation and high/low beam adjustment. While driving home last night on a backroad, I saw that each time the blue high beam indicator on the dashboard extinguished due to an impending vehicle, the green indicator also turned off. The headlights functioned properly externally; nevertheless, I recall that the green indicator light on the dashboard consistently illuminated when in use, regardless of whether the high beams were activated or deactivated. Has anyone else observed this on their devices? Thank you!

Continue producing those gastronomic creations. 👍

I did not use stretch bolts on the W211; I reused the existing ones. Apologies, I cannot recall the torque as it is not included in the extensive thread I created.

Do you possess access to WIS?

Understood. I have a brief inquiry. Last night, I was compiling all the torque specifications for reassembly (any comprehensive list would be greatly appreciated). It indicates that the oil cooler screws should be set to 12 Nm, which seems appropriate; however, some sources state that they are stretch bolts and must be replaced, while others do not mention this requirement. Is anyone aware? I will likely replace them nonetheless; but, they do not appear to be TTY (stretch) bolts. Salutations.

Excellent effort, best of luck; undoubtedly more courageous than I.

Valiant individual! I will remain in the kitchen - suitability varies by context!

The glow plugs are functioning adequately and are easily accessible in the event of failure; therefore, I will defer any action regarding them for the time being. 👍

No sealant on the purple seals, my friend. Should the glow plugs be replaced when everything is disassembled? Well done!

I intended to convey that the purple seals had a sealant applied. To my knowledge, none is required. Am I mistaken, or was the previous owner only exercising excessive caution?

This occurred approximately three and a half hours later...gulp!
