Something that was needed badly

Finally a cool pack that said it fit my 07 525i. It does. This is the one with the alignment tab off to one side. So I went back to order the rest. Now the Amazon site says it doesn’t fit my car. I bought the last one anyway. The first 2 I bought were not right they had the alignment tab in the center.

Work very well

My 07 VW Eos started shuddering when accelerating. It started happening a lot of time to the point I was wondering if I'm going to damage my engine.I looked at some forums and a couple of youtube videos and the most likely cause could be a bad ignition coil. The bluetooth ODB reader + Torque app told me the misfire was on cylinder 1. I swapped the original ignition coils between 1 and 2 and the misfire moved to 2. That confirmed it was the coil that was at fault.I ordered this one from Amazon and replaced just the #1 slot and it's been working very well since then. I kept others so I could replace it if it happened again on a different cylinder. I've attached pics of the new coil and the original coil. My car is at around 68K miles, I bought it used in 2011 and have had it for 13 years.The Bosch 0221604115 OE Ignition Coil worked very well and my car drives really nice. I'm eventually going to replace the other 3 along with the spark plugs later. If you have a VW that's showing a misfire, this is definitely worth a try. It's an easy replacement that most people can do.
