But, at start up, it makes a squealing noise for a minute before it stops and runs normal. As it's doing this, the engine sounds like it wants to stall like it's not breathing, then all of a sudden, it's like it catches it's breath and runs normal. Any clues?
Also, I have the Bently Repair manual for the E53, and I loved it when I had the 6 cylinder 3.0i. But I see it hardly references the 4.4i N62 Engine. I'm not happy about that. That book was my bible! But, I've been reading about the "improved" N62 engine from the M62 and all I read is some bad stuff. Now I'm seriously considering trying to trade with someone for a 3.0i. Does anyone have an N62 Engine that can tell me a little about it?
Thanks!  |
The information you provided is a little head scratcher, I cannot see a link between the squeak and rough start. Likely you need a new belt. The rough idle until 'it wakes up' sounds more like a fuel issue. I have always run Techron in my cars, never had a fuel issue.
I can say that my 4.4 now has 192k miles on it and the only issue has been the VSS smoking which has been alleviated with 0-40 M1 and AT-205. Zero smoke in tens of thousands of miles. Same for my 4.8is. I have come across dozens of N62 equipped vehicles and maintenance is the key. You can always tell when someone skipped on fluids, etc. BMW is also at fault for labeling the trans fluid as lifetime-which it is not. I change my trans fluid very often.
