B58 Engine Cover

[LeonD]

Two attachment points on the OEM B58 engine cover failed on my G. During a recent visit to the dealership, I asked whether a new engine cover would be covered under warranty. The dealership’s response was, “No, but we would be happy to order a new one for you at a cost of approximately $700.”

My answer: “No, thank you.”

I was able to source a BMW B58 engine cover for about one-quarter of the dealership’s price. It’s not an Ineos Grenadier cover, but I actually prefer the look compared to the OEM version. It just arrived, and it’s an exact match—including the insulation—and fits like a glove.

We do have less expensive options available and in this case it has a BMW warranty. For reference:

BMW B58 Engine Cover Part Number: 11-14-8-676-205 (2020–2024 BMW models)

The dealership also offered to replace the engine cover retaining pins for $400. Again, “Thank you, but no.” The retaining pins did not need replacement. For reference, the retaining pin costs about $5.00 each.

I like the looks of the BMW cover over our factory one.

Absurd Dealer service pricing like you encountered will alienate G owners.

After the 1st dealer service , poking around I noticed one of the retaining pins/ grommets on mine was dislocated. The cover wasn't down properly.
I've put a dab of rubber grease on each to mitigate heavy handedness.

Looks Better, of course, no cover probably looks the best. Remembering when engines had no cosmetic plastic trim/ sound insulation..

Looks to me when reinstalling the cover it didn’t get positioned quite right and whoever was installing it gave it a couple of quick whacks with their hand and busted the attachment socket off. When I do my oil changes I take a few extra moments to make sure the pins are lined up and gently push the cover down. If that happened at a recent service I’d for sure be bringing it up for replacement as nobody’s vehicle should be leaving a shop in worse shape than it went in.

Totally agree - the under hood presentation and access of most modern vehicles leaves a lot to be desired. Even my old Rover V8 lump looks a bit more handsome than what you commonly see in vehicles today. Some manufacturers have even stopped putting in vanity covers altogether and when you lift the hood/bonnet you are staring a nothing more than a mess of wires and hoses.

In the UK, they are replacing the engine covers at the next service, as they have a service bulletin on them. Mine was done earlier in the month at its first service.

Yes, my B57 engine cover has been replaced in August - must have been a recall but do not know the reason.

I believe the reason is in hot weather, and when the engine is hot, the plastic has become soft and pliable, and in extreme cases has melted. There are pictures on scambook of the cover melting

If it broke its part of the car not consumable like brake pads they should replace it no problem.

Yikes, I assume the cover is made from some type of thermoplastic? How hot does the engine bay have to be to melt the cover?
