Urgent Help Needed

Ideally I would do a test on yours hot and cold just to compare what is happening.

@Mint couldn't agree more. Everyone's willing to help each other out just so long as the person they're helping isn't @Grumpy =))=))

Tony.

Jokes aside he's delightful. And thats the last joke.

@t-tony I take it you're busy this weekend then? :) I don't mind travelling up to borrow the kit from you, that way you can show me how to do the test too and I can take it away and do the test on a cold engine.

You're more than welcome mate, I'll bring it home and we can do the hot test here and you'll see how to do it. Then you can take it home and do the cold test.

Tony.
 
Thanks @t-tony that's brilliant. Very kind of you. :) Will PM you towards the end of the week.
 
@t-tony, that'll take about 2 seconds off his 0-60=))

I think our Dave might call you a naughty name now mate! Well, when he wakes up anyway.

I got a cam pos sensor code again, despite replacing the sensor two weeks ago.

I thought I'd report all my findings here just in case 5 years down the line someone has a similar problem and lands on this thread.

Yes, I'm still planning to get a compression test done at some point in the very near future.

I've been scanning codes almost everyday and today I got a new one - no codes for misfire today, despite the rough idle in the evening after work but one for the camshaft position sensor inlet signal.

This is funny because the sensors just been replaced. However, the internet has told me two things:

Possible Cause 1.webp

^^ The o-ring on my sensor which has now been replaced twice is orange, apparently the OEM one is black. Wondering if the thickness is different and causing the cam sensor to sit slightly out of position.
Possible Cause 2.webp


Anyway, this post is just something I / someone else can refer to in the future (providing that at some point I find a fix to all these issues)
 
After resetting the codes on Wednesday, got the same cam position sensor code yesterday and today. No other codes at all this time.

Fingers crossed tomorrow I'll be performing a compression test.

If all is good with the test then I may bite the bullet and buy a BMW OEM Camshaft POS sensor, lots of things that seem to be going wrong with the aftermarket ones.
 
Here's what I've done.

Ran the engine up to operating temperature, drove for about 40 minutes.

Wynns Engine Flush - added after the drive, car was kept idling for about 20 minutes.

Oil Change with 0w-40 - immediately after the 20 minutes, old oil was drained and replaced with Mobil 0w-40 (I was told a thinner oil may help free sticking valves)

Wynns Hydraulic Valve Lifter Treatment - added after the oil change

The above was done exactly a week ago

I've been commuting by train this week so the car has only covered about 20 miles since the oil change.

The results:
Saturday Morning - Still rough idling
Sunday Morning - No issues
Monday Morning - No issues
Monday Afternoon (after standing for 7 hours) - slight rough idle
Tuesday Morning - No issues
Wednesday Morning - No Issues
Thursday Morning - No Issues
Thursday Evening - No Issues
Friday Morning (today) - No Issues
Friday Evening (today) - slight rough idle

The results show that the rough idle has reduced significantly after the oil change, before the oil change and valve lifter treatment the car would have a very bad rough idle in the mornings which was progressively getting worse.

The oil change seems to have got things back to the way things were 4 months ago.

Although I should mention that I carried out an oil change a couple of months ago with Shell's 5W-40 - however, that oil change was done without the use of any additives and more importantly on a cold engine (big mistake).

Quite satisfied with the results so far and I hope that the rough idle goes away altogether eventually, but, only time will tell.

Massive thanks to @t-tony as this was originally his suggestion and whilst I was initially a little sceptical about an oil change fixing my problem, it was certainly the cheapest fix to try.
 
Great news Faheem :thumbsup:.
Good advice from Tony,let's hope the rough idling disappears all together.
