Beru products are a very good brand and Beru is OEM to many car manufacturers and other industries.
But for that specific spark plug I have no experience. If Beru says it is for your specific car, then I would not worry about the plug itself.
Hi everybody!
I changed the sparks plugs on my car to Beru Ultra. I was thinking of buying Bosch, but the owner of the shop from which I bought these had the same spark plugs on his 7 series BMW and said he had no problems. Here is a link:

Anybody have any info on these?
Since I put the sparks I only drove about 1.7km Engine runs smooth, but sometimes goes "offline" during idle. I mean it justs stops. Does not happen very often. With the old sparks I did not have problems like that, but they are very old and I had other problems with them (like one or two cylinders not working).
One guy said that the sparks need "getting used" to the engine

Good, otherwise I was worried if its the plug.
The idle is smooth, but when you press the gas, it kind of rattles, meaning the increase in rev is not smooth. It smoothes out at about 3000 rev. But when you are in idle, and press the gas and release it fast (not very fast), the engine rattles (don't know how to describe it the other way) while gaining rev.
Maybe a fuel filter causing the fuel pressure to be too low?

Plugs other than those specified for these engines = stupid.
best, whit
Well I understand that it is better to use the original BMW (bosch). but I already bought these, and their manufacturer seems to be a reputable company. And they actually have BMW as a client:

So maybe its not the plugs? Maybe something else?
Is the fuel pump supposed to work continously? Mine works nearly non-stop. After switching on the ignition it starts whizling and goes on and goes on. In other (edit: not BMW) cars I saw it start, work for a while and stop.

Try this: set ignition on position 2, then the fuel pum should start till the required fuel pressure of 3 bar is there and then switch off.
After it stopped again, try again psotion 2 and listen again. It should stop much faster.
Loosk like the fuel pump is the problem. I do not belive that Beru is a bad spark plug. That is a big and traditional old German company and OEM supplier to many car manufacturers , not only for spark plugs
Switched on the ignition, the pump (the one under the hood) for a short time made a louder noise. But then it was making sh-sh-sh-sh noise continously. It is quiter than the first noise but it makes it continously. I started the engine, let it ran for 15 minutes, shut it down, switched on the ignition, again the same. The shshshsh noise is always there. Is this normal?

I forgat to say that when I first switched on the ignition the pump was making some screeching noise (from time to time).
