What's up guys, my n63 with 53k miles has the DTML come on every few weeks or so for "Cold start "A" camshaft position timing over retarded (bank 2)". I want to replace both A and B while I'm on there.

I took them out and cleaned them with brake cleaner. I thought i cracked the code and it fixed, but no, about a few weeks later the code came back.

I bought aftermarket ones and tried installing them and they don't want to insert in. There's probably a quarter inch that needs for them so sit flush, but they don't want to go in and click. I got the old ones and they go in like butter and click all the way in. I changed the o-rings from the old ones to the new ones and its the same thing, they don't want to sit flush.

So ultimately i bought OEM solenoids and thought they would go in flush, but WTF, it's the same thing. They DO NOT want to go in. I grab the old ones and they go in without hesitation.

Any opinions or insight?
