msinfo_us: wow, I didn't realize that your car's been looked at 3x already. Crikey! If it were me, I would be talking lemon law at this point. Still, you can't really get mad at the dealership. From everything I've heard and read about this issue, it sounds like the problem is that the company that makes these parts (ie valve lifters) for BMW is not making them to specification, or that they are not building them with enough quality to hold specification for any length of time. Hopefully the reports of BMW changing its supplier for these parts is true, and that our engines stay noise free.

I've had a similar thought to what you just said. It's kind of like the other side of the coin. Either the lifters are bad, or the engine is off and making the lifters go out of spec. If so, hopefully the diagnostics will identify it.

just curious ... I have about 4,500 miles on my car after an ED delivery this past April. I am now noticing the lifter noise more often since it has become colder (around 32F). Has anyone noticed the same?
Those that have gone to the dealer with this problem, have most just believed you up front and just planned on replacing the lifters? If the temps get into the 40+F range, my lifter noise is very intermittent. |

[QUOTE=rkg]Those that have gone to the dealer with this problem, have most just believed you up front and just planned on replacing the lifters? QUOTE] I don't think so. There is a normal lifter noise and there is ticking noise. A lot of people confuse them. Plus as much as we think (at least some of us do) we know all about our cars we are not profesionals (not all of us) and if dealer were to rely on our dignostics and take everybody at their word and impression only they'd be wasting a lot of time and $$. So, I think you have two options here if you want to bring your car for repare: best if you can show them noise while you are there or give them directions/explain when and how on how to replicate it. Just my $0.02. GL

I definitely have a ticking noise caused by the lifters. It is the same noise and problem I have had on race cars (351 V8's) that required new hydraulic lifters to rectify the problem ... now the fun part, getting the problem reproduced for the dealer without murphy's law kicking in.
I am just wondering if BMW is keeping this like a hidden recall whereby only replacement is done if a customer complains about it. |

Well, I got my car back today .... un-repaired. With the exception of one time last week they could not reproduce the ticking noise. We've spent over an hour together (they volunteered to stay overtime -- which was really nice) with a few mechanics, foreman and service manager trying to get it to tick and of course Murphy law would not be tricked. Best we've got is a very light tapping noise but no ticking. We end up comparing and discussing different tapping noises. We've checked three or four cars. Two had tapping noise, one 328 no noise what's so ever and one 325 no tapping noise either. They say that tapping noise and ticking noise are not related and that tapping noise is normal (even so clearly some cars do have it and some don't). But related or not tapping noise was not my concern and ticking noise is still un-repaired. So, from what I've got they need ticking noise to be there pretty consistently to troubleshoot. I understand their reasoning but at the same time we all know problem is still there and I'll have to wait for it to get worse than do it all over again. So, the question that I have is: - Even when ticking will be there more or less consistently and they attempt to repair it for a forth time which is again going to take up to a month there is still no guarantee that it won't be back again. My car was in the shop for a month and half already in six month since I bought it, three (counting this time is four) times they already tried to fix it -- how much is enough? Should I continue trying to get it fixed in hope that next time is the last or just give up and start talking about other alternatives? What would you do?
PS I just thought of one more question. What do you think is fair/what would you do when I get a call from BMW NA to rate their service? On one hand they were courteous and even stayed overtime with me to troubleshoot and on another hand they heard the noise (ones but still), I left a recording of the ticking noise for them as well and they did not repair it. So, if I say I am satisfied I would be lying but if I rate them low they might loose their bonus or something. What do you think I should do? Also I discovered something else. Just was going thru the paperwork and was like what the hack. I picked my car from dealer yesterday 11/1/06 but paper said 10/26/06. Service manager left me a VM at 5:45pm (15 minutes before they close) on 10/26 saying he can no longer reproduce the noise. I spoke with him next morning and he agreed to continue to diagnose the problem. So I went back to check the dates on previous papers and it began to make sense -- 25 days before plus 3 days now (based on his dates) total 28 days -- 2 days under 30 day lemon law policy for NY and most likely a red flag for him at BMW NA.

i just experienced the same problem tonight for the first time, it was 31F outside, the car was cold and the ticking sound and pitch changed accordingly to my engine rpms, then after it was warmed up or about 4 miles of driving, it disappeared...

I have been logging my lifter ticking noise since my car (4700 miles) is going to the dealer on Nov 20th for this issue. Basically, I sporadically get the noise on cold starts in the morning (garage around 40F+) or if the car warms up and then sits for a few hours ... it is then ticks for a few miles or so until full warmup.
My SA did not admit to this being a problem, but sure made it sound like this is not the first he has heard of it and will let me know the outcome ... we shall see. |

Found this on bimmerfest "but imagine if somebody's lifter had seized into the head, and the ticking noise was the rocker arm coming heavily into contact, until one day the rocker arm bent itself out of alignment and no longer came into contact with the lifter..... the person would now have damaged lifters AND rockers to replace....". Sounds like he is right on. On my second repare attempt they replaced all lifters and ticking was still there. Than they repalced lifters, rods and rockers and ticking stopped only to retun a month later. What else is there that can damage lifters?

I think you are right. I remember reading it too. They checked camshafts for unusual wear and found none but they've never replaced it. Could be last peice of the pazel. Thank you.

Ages944, to you point above ... found this guy on bimmerfest who "had the ticking noise on my 325i after only 2months - it went into the shop and they replaced the camshaft and the valve lifters - it was off the road for 14 days waiting on parts." This was done mid Feb 2006 seems he is fine ever since.

Lifter springs
Went to my dealer with the ticking problem. Tehey were not able to locate a service bulletin on the problem. They contacted BMW of N America after they were able to duplicate the noise. Replaced 2 lifter springs that they felt were machined inproperly. Cleared up x 4 days, then I heard the noise again, but less pronounced. They were not able to duplicate. As the weather get colder, i expect the problem to surface again. Have not heard it in a week.
Let me know how you make out. John |
