2000 bmw 528i shudders when first started and when it idles
We have a 2000 528i with 111,000 miles on it, we bought it used about 15,000 miles ago. It ran GREAT for months! The car starts really rough now, and almost sounds like it's "choking". It runs rough until the RPM's are up, then shakes again at low speeds and when sitting at a light or stop sign. It had done this off and on for about a week, then the "service engine soon" light came on and now it does it every time we start it. My son said it feels "like one of those old fashioned cars that are bumpy". It does! The oil lights still have 3 green bars on the gauge. We don't yet have a trusted mechanic for the car, so any and all info would be greatly appreciated! Thank you in advance!

I had the same issue with my 2000 528i. You more than likely need to have the Vanos seals replaced. BMW will tell you that the Vanos unit needs to be replaced but the problem is more than likely isolated to the OEM seals that shipped with the Vanos. This issue has been reported by several BMW owners. This issue has been thoroughly documented and reported to BMW in an effort to seek a corrective fix. Since BMW failed to address the problem, the guys that investigated the issue started their own company providing superior Vanos seals to the deficient OEM Vanos seals.
The company is Beisan Systems, LLC. I ordered their Vanos seal kit and had them installed at a local BMW performance shop for less than half of what BMW wanted to charge me for a Vanos replacement with the same faulty seals. Besian also provides step-by-step DIY instructions; if you have the time.

If the symptoms came on rather suddenly, another possibility is one or both of the cam angle sensor(s). The 2000 528i has one for the intake cam and one for the exhaust cam. Our car was running a rough at idle, drove ok, but occasionally stalled at traffic lights. It turned out to be the intake cam angle sensor. I changed it my self without a lot of trouble.

The tools alone will be $1000. Not something you will want to do yourself. I good BMW specialist will charge about $1500. Its also highly unlikely your chain is bad. It normally is going strong after 300,000 miles and is the LAST thing that will break. Why do you think yours is bad?? If it is because the car won't start, then I will tell you there's 99 things that it could be and if timing chain is even on the list its dead last. A BMW ain't no Toyota.
any check engine light? Try cleaning the intake throttle plate with a lightly soaked paper towel, the plate is located in the intake; with throttle cable attached to it at the top of the engine near the bellows boot attached to the air cleaner assembly that comes off the mass airflow to the intake. It looks a 3.5 mm cd. That plate gets dirty and throws off the idle air control.
The wiper relay is a common cause of this failure. It is not very expensive and easy to replace. Search Google to find a replacement and instructions. Use these terms: e39 wiper relay
If your talking about what would a dealership change, it generally consists of a tune up, including spark plugs, plug wires, air filter, oil change, pcv valve, and fuel filter. Thats also usually when they want to replace the timing belts. There may be one or two other things specific to BMW, but generally thats what you can expect.
Pressure test cooling system to determine origin of leak. Radiator and coolant reservoirs are common problems. Vehicle is very difficult to purge air from cooling system and may take multiple times of idling until thermostat opens. Sometimes help to rev engine to about 2500 rpm 5-8 times to help build heat and move coolant through system. Must have heater on while performing this task.
telemachas is totally correct with this type of car,also when pulling one of these engines apart i also found a lot of wear on the piston ring groves ,although rings were good the pistons themselves needed renewing .This would cause oil to be pumped into combustion chambers on initial start up.Problem was the cost of parts was more than the car was worth so customer bought another car as this one had been inported from germany and was so rusty as well it was just a scrapper and worst of all it had no air con
The idle issue is normal. The idle is controlled by the ECU. There are no adjustments for the idle. Regarding the knocking noise, that could be several things, and I am hesitant to comment without hearing it. Take it to a Toyota Dealer & have a tech listen to it. We are very good at identifying noises on the service drive.
