It begins shortly before the one-second mark of the video and sounds nearly like a belt slipping.

Nothing but a loud "pop/click" could be audible when I played the audio back at maximum volume on my PC. Just wanted to clarify that I would love to hear the sound you describe. If it were knocking from low-grade petrol, I wouldn't hear it like you're describing it; it would be more regular and repetitive. Your description seems to indicate that the turbo charger might be ramping up at that time. Maybe the turbo's heat shield is flexing.
-
Just before the pop manipulates my phone, a sound happens. From inside, with the windows down, I videotaped it. Even when travelling at high speeds on the highway, you can hear it through closed windows. It could be spark knock, according to someone on Reddit... Hopefully not, because I exclusively use premium fuel.

I hear more of a "pop/click" than a metallic chirping sound, and while I find that intriguing, I have no clue what that means. How did you manage to get the audio recording given the circumstances in which the noise is said to occur? I thought you were leaning out the window of the car!

As of 05/24, I own a 25 CX-70 Turbo S Premium. I hear a metallic chirping sound emanating from the engine compartment whenever I accelerate, whether by downshifting or holding a gear, and this only happens when the engine is completely warmed up (the temperature indicator won't go higher than one tick below half). Even when the temperature is only slightly below full, it remains silent while in park or neutral. This noise is reminiscent of the wastegate rattle. Is anyone able to guess what it might be? This doesn't seem to be a problem with the gearbox, heat shield, or drivetrain; it occurs exclusively in gear, under load, during acceleration, and when the engine is well warmed up. This is a recording of spoken words. Also, I haven't noticed any smoke or leaks, but every three to four thousand miles, I seem to drain nearly a gallon of oil.

Uneven Idle and Knocking Noise from OM651

I am hoping to get it to one of the Indi that I have contacted. -

This is just one more reason why you shouldn't use the start-stop feature on these engines; it could be related to the chain. -

Are you okay? Perhaps you are in the vicinity of a Merc Indi. -
Uneven Idle and Knocking Noise from OM651

A star session could be the next best thing for an injector that's about to go out of business. -
Greetings, everyone! Might mean a lot of things, but it's not really clear. My 2013 Mercedes C220 CDI AMG line with an OM651 engine has covered 167k miles with the sole problem of a split turbo pipe. Has received routine maintenance and, up until this point, has performed admirably, pulling and driving like new. For your information, an ECU remap was performed on it approximately nine years ago. I can attach a video if needed; I only noticed a loud engine sound and haven't driven since. The car is trembling slightly, the knock is audible, and it idles less than ideal. On rare occurrences, the knocking stops, and the engine starts up normally; nevertheless, on occasion, it starts up again. The question now is, is it worth repairing because it's an injector knock, is it worth it because it's a bottom end knock, or is it something else entirely? I'm trying to get an appointment with a Mercedes specialist to diagnose it, but it's taking longer than expected because most of them are booked up weeks in advance. Icarsoft does not display any error codes, and the engine light is not on, by the way.

Supercars from Nick Mason in the garden
keithmerc220 replied to Darrellll's topic in General Discussions
The great unwashed have considerably easier access than ever before to get up close and personal with supercars these days, so it's definitely personal. Nick, his wife, and their beloved Ferrari were a sight to behold at the former residence of Queen Camilla. Describe myself as "old fashioned." -

Indeed, I am concerned that once he departs, the 1962 250 GTO (which was recently valued at approximately £50 million) will no longer be visible to the public and will most certainly not be placed on someone's lawn so that the general public can examine it closely, just like I was able to do a few years ago. -

Those of us who don't drive "need" to-be-seen Supercars in his parking lot Bikes could be used for the final few miles. Wow, it's terrible. If not, you should allow at least an hour for entry and another hour for exit. And even more if it rains and churns the field. However, take advantage of this while you can because Nick Mason is 82 years old.Hoping you could make it? -

Be aware, as I indicated a year ago, the traffic on the Bath road, the only way to reach Middle Wick Lane, is becoming worse during this time of year. The other day, I was driving through that area when I noticed AA "yellow" signs alerting drivers of the heavy traffic. By the McDonald's on the bypass, I even noticed more displayed further down the road. Reason being, the area's bypasses are undergoing a tremendous amount of road construction. Since there is only one route to enter Nick's house and one way to leave, through his neighbor's private land, I am unsure of how they will enforce this. It is my sincere hope that no one will miss this event, so I urge everyone to arrive early on Saturday. It would be unfortunate if this event had to be rescheduled because of how popular it is. You may always spend the weekend at Nick's place and then head a little distance to the Cherished vehicle exhibition on Sunday.

Tire impressions on 18" wheels - EV2 ownership

If you're still having trouble with high grip after adjusting the tyre pressures to the correct levels, try checking the vehicle's PDI import center; sometimes vehicles leave with the pressures set to transport, and dealers aren't great at fixing this. -

61 kWh should be more than enough for me as I'm not a boy racer. I will be satisfied if it can securely overtake when needed. During my test drive, I noticed that the Renault 4 possessed a surprising amount of power. Instead of waiting for the Kia, I would have bought it immediately if it had a battery with a little more range. In my opinion, the R4's cabin is both very sophisticated and attractive. In particular, I appreciate you taking time out of your vacation to provide feedback in the form of your comments. -

Their enthusiasm has been contagious. There is a lot of available torque; yet, this 42 kWh battery is slightly more powerful than the larger battery variant. -

It seems like the EV2 is a good fit for the 18" Hankook tires. They have been standard on VAG vehicles for a while now. In my experience, the tread life and traction of the Hankook Ventus Prime 3 or 4 tires are satisfactory. On the winding, hilly roads of Cornwall, how would you rate the overall performance of the car? It would be helpful to hear about your experiences with steep climbs as my test drive did not involve any. -
After a 40-mile round drive to the Eden project, I thought it would be a good idea to share my (positive) feelings today. I was curious to see how the Hankook tires fared in dry and wet weather as I've never had a vehicle with those tires before. These tires were straight out of the factory; they had the low grip of new tires and made the steering seem too light. It's something I've seen before when tires are brand new, so I wasn't worried. The novelty has worn off, and the right amount of grip has finally arrived. From what I can tell, they are up to the task of handling the EV2's (42kWh) nimble acceleration with ease. The return trip on the A30 over Bodmin Moor today was accompanied by heavy rain and a lot of standing water due to the weather. Even with 400 miles on the tyres, they handled the road with ease, and I noticed no slipping or swaying of the heavy steering. I will add a couple of spots where I can tighten the grip when I return home, so I will do that eventually.
