I'm not a huge car guy... Changed oil on a few different cars I've owned, installed exhaust on an 05 Mustang, nothing that a guy with a few tools and access to YouTube can't do.
With that said, I'm not much for diagnosing issues.
I recently bought an '05 BMW 545i as a "hold-me-over" vehicle. It has 134K miles. The body is super clean, looks clean under the hood, and CarFax was clear. It was priced right, I had the equity in my old car, and I'm going to order a new car later this year. This was supposed to be something for me to drive with no payments until my new car comes in, probably in mid-2017.
As is the risk buying any used vehicle I noticed an issue after only about 100 miles that wasn't present during the test drive. The vehicle runs very smooth. It shifts smooth, I feel like the accelerator is responsive, and the average MPG shown by the on board computer is about 22mpg.
I started to notice, however, when I come to a stop at a red light or stop sign (basically when I'm stopped with the vehicle in gear) the car will shudder. It's not extreme but the idle is around 750rpm and it basically just shakes when I'm sitting still. As soon as I take off it smooths out and there are no issues while the vehicle is moving.
I know a possible source is the engine mounts. I haven't tried a hard acceleration from stop followed by abruptly letting off the gas to see if the engine "clunks" as it sits back in place. I will try that this afternoon. Until then, or in spite of that, does anybody have any other ideas as to what my issue could be?
**Adt'l info** So the issue seems to occur only when the engine is hot. When I drive after it's been sitting for a while it's fine. If I go somewhere, say the store or the bank, and shut the engine off for only a few minutes before starting back again, the issue returns. PLEASE HELP!
No smoke from exhaust, coolant levels are consistent, oil levels are normal, SES light on
