I致e had my 535 for about 2 1/2 years now. About a year in I started getting these slight shakes I get them either when I知 holding a speed over 45 or when I知 at a red light it値l shake and then go away then come back, I brought it to my local shop and I was told it was a vanos issue I had them replaced. But the code came back then I got the whole camshaft timing unit replaced, still the same shakes. After that kinda gave up on throwing money into finding the problem and I just drove the car with the shaking. Now I知 getting these codes 2AAF fuel pump plausibility and 2A2D fuel low, pressure system, fuel pressure. At this point I don稚 know if I should have my low pressure fuel pump changed or high pressure or both?

Shakes are generally indicative of something going on with the suspension system, your rims or motor mounts. Depending on your mileage and previous replacement, I would look at:

• shocks/springs
• motor mounts
• alignment
• ball joints
• bent/cracked rims
• rim hub bore (if not OEM wheels)

Here痴 the thing. It痴 not a suspension issue. It happens at idle as well while I知 at a light. And while I知 holding a speed of 45+ it痴 like waves of shakes that I can feel in my chair. I致e had suspension work done and also looked at everything is fine there.

Not sure how an intermittent coil would act...but it would probably cause a "shaking" sensation when it wasn't firing...or a completely "failing engine" sensation...not sure which. Or possibly a plug issue?

would that set off the fuel pump codes as well?
