Hi,
I don’t know if anyone can help?
i bought a w211, 2005 e350 petrol auto a few months ago and all was fine and was driving just great and then all of a sudden it became slow to start up when the engine was hot and sometimes would feel like it would conk out when driving along but never did, at first I thought it was the battery but I had that checked and all was ok as it’s a new battery, I then plugged in my diagnostics and found out it was the crankshaft sensor, cam position sensors, ignition coil and also found out that the intake manifold was stuck.

The codes I had at that point were:
p0335
p0336
p0016
p0017

p0352
P2006

Today I replaced the cam position sensors & magnets, the ignition coil and the crankshaft sensor, everything is working perfect again, the car fires up first time whether it’s hot or cold and it doesn’t feel like it’s going to conk out when driving, in fact drives much better than it did.
I plugged the diagnostic back in and now only have 3 error codes
p0016,
p0017
and
2006 (intake manifold problem that I haven’t attempted to fix yet).

when I replaced the cam position and crankshaft sensors there was a lot of oil in the wiring connectors, I tried to wipe it off but I’m worried that it’s got into the wiring itself and is causing me to have the p0016 and p0017 codes, I can understand how oil got into the cam sensor as there was a leak from the magnets but I can’t understand how there was so much oil on the crankshaft sensor connection?
Has anyone else had that issue before?
Could this be why I’m getting the P0016&17 codes?
also when I disconnected the old crankshaft sensor the connector latch piece broke off so now the new sensor is just plugged in with nothing keeping it into position so maybe that’s another reason why I’m getting the error codes?

if there’s anyone with any ideas or have had similar problems I would love to hear back from you.

as I said the car is starting first time with no hesitation and is driving really well.

 

What country are you in? Search for balance shaft problem. If you have an M272 engine, those early ones til about 2007 had bad balance shafts and the P0016 & 17 were usually indicators. Intake manifold also goes on the M272 although sometimes you can just repair it with repair kits found on eBay. However those are just temporary fixes as eventually bits of the intake will break off and end up in the engine potentially causing damage.

 

Hi thanks for your reply, I’m in England,
I’ve done lots of research online on the p0016&17 problem and I suppose I’m trying rule out the cheapest things first before I try and tackle the shifters, in a way I’m hoping that the oil that’s got into the wiring connectors or the broken crankshaft sensor connector will be causing the codes as I’ve read that bad wiring is also a cause, I just wondered if anyone else had the same issue?
the car runs beautifully and I’m determined to get all the codes gone, hopefully I can save the car from the scrapyard without too much cost, fingers crossed

 

There are many threads on this forum about the balance shaft problem. There's also several videos on youtube on how to check to see if you're affected by it.
