The first drawback was the confusing instructions. This has in some respects more messed up than it has helped. It has been described things that were not at all possible at the Schlüsel.
With a bit of logical thinking what the problem but easily solved.
But the decisive point. Disassembly of the EGR key was not a problem, now it came time in the inner workings of the new key einzusetzten. Firstly, the chip in the new key was very loose and not nearly as strong as in the AGR. After einsetzetn it came time to assemble the key again. At first glance, no problem. But then but easier said than done. After you have finally zusamen the key to such an extent without the chip wegruscht or parts do not fit, it went to the screwing. The built-in chip of the old EGR the new key was thicker what screwing very difficult. When the key was then screwed endlisch course kammen further problems. The key could be PRIMMA aufklapen before mounting the chip, even before screwing it went great, but after the bolts were there this was no longer possible. The complete housing was so much pressure that the key is no longer flipped open. Of course I wanted to fix the problem but Dan went wrong everything. The first herrausdrehen the screws I realized that this is not of oher quality goods & as guessed they gave the second time already the ghost. Because the key had to be very firmly screwed on the application of the chip it was then no longer possible to loosen the screws. When trying to turned the screw head of the inferior screws kaput directly. What to follow had the key only by force to open was to at least get to the chip and these will be reinstated to the old EGR key. I was rarely so disappointed by a product as of this and therefore I would like to avoid any rat from buying from the unnötogen stress that more has not brought me this purchase.

I hope I could help some order.
