    Need Help...Broken M5

    Also another thing worth mentioning is that the car (3.6) has had 3.8 cam gears installed along with a chip. Now is this anything to do with the cams being mistimed? Does anyone have any info or stories of this happening as I can't really find much info on it online. What are the differences between the 3.6 and 3.8 parts, in terms of size, number of teeth etc. Bear in mind, this is something that was done quite a few years ago, and the problem has only arisen now, maybe 20-30k miles after. Quite a few people are pointing me towards a failed tensioner as apparently the unit in the S38 is highly complex and different from a regular tensioner. Appreciate all the help everyone

    Quick update: Got a call this morning, they took the valve cover off and it turns out the inlet camshaft has skipped 2 teeth and it’s obviously mistimed. He said the camshaft itself is slightly damaged but he didn’t say it definitely needs replacing. He also mentioned that it couldn’t be a bad tensioner as apparently on S engines that’s not a common fault or something? So that’s what we know so far, he’s got to dig deeper now. At least we’ve got some progress but I’m praying it’s not going to be a huge job and more importantly a huge bill.

    Yeah they’ve checked all of that and they said they’re fairly new, the whole lot, so it can’t be that

    Update: The maf came back as all clear, no faults. The mechanics are quite baffled at what it could be. He said he’s eliminated anything electric and is 99% sure it’s not an electrical issue. Also pointed out that it’s got the wrong injectors but that shouldn’t stop it from running though. They said next on the list is to check the cam timings. A lot of head scratching going on...

    Hmm that’s interesting, I’m still amazed at how instantly it just went like that. Very very strange. Thanks for the info though, appreciate it.

    Also can I ask what was the reason for getting it refurbed in the beginning? Was it faulty or was it just because you were doing everything else? And did it ever do anything like this during your ownership? Just trying to put the pieces together and figure out what’s going on haha

    Oh shit! I did go through all the receipts and did notice it was refurbed along with the throttle position sensor but didn’t take note of who and where. Wow, will give them a call tomorrow as the garage said they posted it off on Thursday and they said earliest they’ll have any news will be his Thursday which is a bit long imo. I take it there aren’t many companies in Cambridge specialised in this kind of work. Must be the same place, right? and also begs the question, why would it break after only 3(?) years?

    Update: The car is at my local BMW specialist. After a few days of tests they concluded that it’s 99% the MAF which is faulty. They said the spark is good, fuel pressure in the tank and at the engine is good, no air or vacuum leaks. They’ve sent the MAF off to a company in Cambridge who are apparently specialists in this field, they are going to test it further. Unfortunately the new unit is £2000 but no longer available to it will have to be refurbished. Hopefully I’ll hear back from them today as I took it there last Tuesday.

    No overheating, no warning lights or any form of indication that it’s going to happen. Literally as I went to pull off from the lights the car stalled, so I thought I was in 3rd, tried again and realised the engine isn’t revving at all. Unfortunately it went beyond my knowledge and it’s currently at my local BMW specialist

    Yeah all visual checks, I have basic knowledge but people have been suggesting me to do this do that and to be honest I neither have the knowledge or tools to carry out such tests.

    I have checked most of them but I’ll give it a thorough looking at. How do you actually check for vacuum leaks apart from feeling and listening for air? As I said most if not all hoses are newish so I’d be surprised if it was something along those lines. Already removed coils & sparks and they seemed fine. Would it even run if it had bad compression?

    So I purchased a beautiful 3.6 M5 on Wednesday 140k on the clock but it’s had an engine rebuild with new block about 40k ago. Drove it about 90 mins, and literally 2 miles from my house it failed on me. Started spluttering and coughing at a set of lights, and wouldn’t rev. It idles very rough at about 800rpm probably on 4 or 5 cylinders. It almost dies when you try giving a rev and has cut out many times also. So so far I’ve checked the fuel system, that is all fine and fuel is not an issue. Spark is also there (obviously not time correct) but it starts up fine every time. If you leave it it will idle obviously very rough but it runs on it’s own fuel fine. I’ve also checked all the fuses and relays and changed the fuel pump & DME relay just to be sure. I checked the paperwork that came with the car and the MAF and throttle position sensor were both changed about 2-3 years ago if I remember correctly. When he MAF is unplugged on idle it cuts out instantly, and won’t start without it plugged in anyway. Also the car has had a huge amount spent on it with various rubbers/hoses replaced with genuine BMW parts so I don’t think a vacuum leak should be an issue. I’m 99% sure it’s electric/sensor related as it happened instantly, not gradually over time. I’ve had it plugged in to a diagnostics and didn’t show any fault codes. It wasn’t a specific BMW one though. I’ve also tried pulling out the coils one by one while it’s idling and they all seem to be fine. Contacted the seller and he said he doesn’t have a clue and that it’s never happened to him. There’s nothing to suggest he knew about it as I viewed the car previously and we went on a spirited test drive and it ran like clockwork. Any ideas on what could be the issue? I really want to make it to Gaydon on Sunday and I’ve tried a few garages/specialists but they’re booked for a whole week-10 days. Any help/suggestions would be appreciated.
  13. I know it’s the wrong section but I’ve posted in the events section and it’s got no replies. Surely a few of you are coming this year? Also would love to arrange a little convoy as last time there was a group of 8-10 of us from this website and going through the country roads was awesome
  14. How easy of a job would this be? Just for the fronts of course, I assume you would wire the indicators to the side lights right?
