A Class 2013 intermittent P2616 fault

[OrangeJuice]

Hi, Own a 2013 A Class A180 petrol. Recently had a injector replaced - after 2 weeks, a new fault code appeared P2616. At times the car loses power and does not accelerate. The fault does not occur immediately, I could be driving for a day or two without issues.
I have cleared the code several times but keeps returning and have replaced both cam sensors and cabling looks good.
In the end, I went to the same authorised garage that replaced the injector and they carried out a full diagnostic and the report reads:

P217800 The mixture (cylinder bank 1) is too rich in partial load operation
P261612 The output signal for the position of the camshaft has a short circuit to positive. There is a short circuit to positive.

Any ideas of what it could be?

Cam position sensor would throw the mixture out of killter.

Both Cam sensors have been replaced

Could still faulty though, unfortunately.

Could the replaced injector be at fault (it was reconditioned part) ?
Theory is that injector could leaking, it may cause P217800 which in turn triggers P261612 ?
I forgot to mention I can smell fuel in the car when the fan is running after the injector was changed.

Sounds like it could be the culprit.

Was the injector coded in properly?

I don't know if the injector was coded in. A Mercedes Approved garage replaced it. They have recently ran a Xentry report, which only flagged the two errors I mentioned.

If they are Mercedes approved they are a main dealer. They need to spend some more time diagnosing it.

Has the wiring been tested if the cam sensor is new? Was the cam sensor a genuine MB/Renault part?

Hi, I noted the cam sensor did not have the Bosch stamp on it but only the correct part number, though it came in a Bosch box. Since then, I picked up another, which has the Bosch mark, its not from Mercedes but at least it has Bosh marking. Will replace and update thread.
