E220 Crankshaft position sensor location

I checked from the top and I can't even see passed all the wires and pipes, unless I have to take out some components, such as filter filter housing or the EGR. I might damage some wires in the process too.
I just hope a mechanic can replace it without taking the engine out.

It doesn't need the engine removed.

It can be accessed by an experienced MB specialist as previously advised.

UPDATE.

I have now had diagnostic test by professional mechanics. All the faults apparently electrical problems. But, I have been quoted up to £2000!

Below are the problem. All of them seem easy to be done.

P034031. The position sensor for the intake camshaft (cylinder bank a) has an electrical fault. The signal is not present. I have taken the old one out and will be fitting a new one. Very easy to locate as it it just on the top of the engine next to the injectors, as in image 1 (attached).

I'd like to get some direction/advice on the following faults. I have two injectors (used but functional as they have been tested)
- P020100. The fuel injector (Cylinder 1) has an electrical fault or an open air circuit.
- P020200. The fuel injector (Cylinder 2) has an electrical fault or an open air circuit.
- P020300. The fuel injector (Cylinder 3) has an electrical fault or an open air circuit.
- P020400. The fuel injector (Cylinder 4) has an electrical fault or an open air circuit.
- P019315. The rail pressure sensor has a short circuit to positive. There is a short circuit to positive or an open circuit.
- P009000. Pressure regulating valve 1 has an electrical fault or open circuit.

I have told the camshaft and crankcahft sensor kit need replaced and the whole engine has to be taken out. Hence, a big job costing up to £2000. How much of that is true? I can't really tell.

I would say they are not a professional mechanic. The fault codes should be just part of the investigation.
If everything was working before an injector replacement, they are not all suddenly going to go pop. Wiring got damaged or one sensor damaged causing a 5v short. That would knock out all sensors on that supply?
Injectors are connected to two separate drivers in ECU, nothing to do with the 5v supply. Can't believe these have both failed at the same time as well.

Take it somewhere else to look at.
