Camshaft timing for e90 320i

crank shafts are set to tdc cam shafts are set for valve timing
if the crank shaft is turning but the cam shaft is not then the timing belt/chain has broken

I am not sure how it can be out of time when the dots * to * line up exactly on both the front and rear cam. I just dont understand how one is supposed to get the service bolt in the rear cam since it is on the bottom of the exhaust gear.

It's on the front of the cam shaft near the timing chain. You have to open the camshaft cover to access it.

You need to take off the timing belt (or chain) cover and see why the one camshaft is not turning. Maybe the belt for that cam broke or the cam has seized from a bad cam bearing. One camshaft should be for the intake valves, the other cam is for the exhaust valves.

Camshaft position sensor gives the position of cam related to the engine crankshaft which is useful for the fuel supply; ignition, injection, valve opening and closing system. Magnetic type sensor is used on the timing cover over the camshaft gear. Camshaft position sensor is same as that of crank shaft speed sensor in terms of construction and working.

Have you ever replaced the timing belt?? If not the problem is likely to be a loose worn out timing belt. A floppy belt will play havoc with the sensor signals and trigger a check engine light and a camshaft sensor code.

In this case the solenoid needs to be replaced.The error code in this case is P1533.This code is many a times noticed on Mercedes Benz.

P0204 is miss fire detected on #4 cylinder.

Below is TSB from VW on your problem...a common one.


Technical Product Literature Transaction No.: 2015153/1
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory Release date: Jun 29, 2007
Condition
15 07 04 June 29, 2007 2015153
MIL ON, DTC P0087, P1093 or P2293 Stored in ECM Fault Memory
MIL ON with the following DTCs may be stored in ECM fault memory:
DTC Description
P0087 Fuel Rail / System Pressure - Too Low
P1093 Fuel Trim 2, Bank 1 Malfunction
P2293 Fuel Pressure Regulator 2 Performance

Technical Background
Excessive wear of intake camshaft lobe that drives the high pressure fuel pump. The wear limits maximum pump piston lift, causing fuel rail pressure fluctuations.
The wear on the camshaft lobe can also lead to wear on the base of the high pressure fuel pump cam follower.
Production Solution
Increase surface hardening of camshaft lobe for the high pressure fuel pump
Improved intake camshafts have Part No. 06F109101B.
Service

• Remove the high pressure fuel pump and visually inspect:
1. Base surface of the cam follower -6- in contact with the camshaft lobe.
2. Tip of the high pressure fuel pump plunger.
3. High pressure fuel pump camshaft lobe.

If the base of the cam shaft follower looks like -C- or -D-, no excessive wear is present.
Cam follower and camshaft should not be replaced.
If the cam follower base surface is excessively worn so that its surface is concave -B- or missing -A-, inspect the intake cam shaft lobe for wear.



If the high pressure fuel pump camshaft lobe shows excessive wear, replace the intake camshaft with Part No. 06F109101B and the cam follower with Part No. 06D109309C, see Group 15 Engine - Cylinder head, Valvetrain in ElsaWeb.

Inspect the tip of the high pressure fuel pump plunger for excessive wear.
If excessive wear is found the high pressure pump must also be replaced, see Group 20 Fuel supply in ElsaWeb.
Tip:
High pressure fuel pump plunger damage is only possible if the cam follower base has a hole in it and the plunger tip has come in direct contact with the camshaft lobe.
If no excessive wear can be found in the high pressure fuel pump cam follower or intake camshaft lobe, or if the damage is found in camshafts with part number 06F 109 101 B, create a Technical Assistance Contact Ticket under the Concern Type Engine and Engine Electronics in ElsaWeb.
Attach the complete diagnostic log to the contact, and call the VW Technical Assistance Center for further assistance.
