He works to identify why things like this fail, and offer up improved components that won't fail in the same way. He also has a great reputation for supporting his customers.

Unfortunately if you didn't get the coil pack through him, he obviously won't warranty it... but $150(+core) is still a lot cheaper than paying for a new one and have it fail the same way

I had a similar issues with mine I forget the code but it was probably p0012 or something.
Anyways I took out the solenoid and opened it up. It's really well sealed. I had to basically crack it open. Once opened I put flux on the pins and resoldered the dry joints. Sealed it up with some silicone. Reset the code. Car runs like a charm.

This is all I can do testwise. It wont continue testing beyond this.

I found his name after some searches and PM'd him. He really knows what he's talking about... Got a return PM back very quickly. I will start with the vanos solenoid per Raj, and work from there.

Thanks for your help too Drewster!!

That actually looks like the engine is out of time.. since it's not getting close to 60* it's just stopping the test. How did you use the timing bridge? If you have to lift one side of it to insert the pin, the engine isn't in time..

No worries! Glad to help - don't forget to clean/ rebuild as much as you can so you don't have to go back in there. Doing the entire Vanos procedure is pretty good peace of mind.

That's where I am puzzled, the entire vanos system was replaced, albeit 40k miles ago, but still should serve as a longer peace of mind.

I think the issue has arisen from how the PO drove 70 miles per day and I drive shorter trips in the cold, never properly warms up....

The pin inserts fine (slides in and out with no resistance basically), with the alignment bridge sitting on the engine head.

I took the end cap off the inlet side of the VANOS and the piston was completely bottomed out on the end cap, exactly how it would look when you set it up in the first place. And there wasn't much oil coming out, which leads me to believe that the piston was not even moved during the VANOS test, so I am not sure how it could have only read a retard value of 51.5 if the alignment bridge was used.

Yeah.. BMW did some ground-breaking stuff, but they're not well known for getting it right the first time. Some of the stuff simply comes down to design flaws.

I agree, it sounds like the test essentially went for maximum cam retard (where it's at now), got 51*, and stopped. Are these stock cams? Crank locked at TDC? Have the wheels on the back been adjusted in any way? I'd post a YouTube video of how you're timing the car and just an overall view with the valve cover off... hopefully someone can spot the issue because it certainly doesn't add up

Yes stock cams. Crank locked at TDC. I don't think the wheels in the back have been adjusted (I hope the wheels in the back dont rotate if you bump into them with your hand or something.) Cams were not removed or anything and nobody has touched it other than myself since I first took it apart.

The only thing that I can think of is the following where the cyl 1 lobes are not symmetric when the alignment pins are inserted, but I see a similar configuration of the cyl 1 lobes in TIS documentation.


Ya nothing adds up to me! At this point I am just glad, knock on wood, I haven't bent anything.
