Common failure points to check during Inspection II?
My car is going in for Inspection II soon (came due around 45,500 miles). I'm developing a list of requests for the dealer, including that they return the valve adjustment "worksheet" describing shim additions/removals.
I assume they will have easy access to some of the infamous VANOS bolts? Should I ask them to re-torque and loctite them? Also, since the previous owner stupidly skipped the 1,200 mile service, it's essential that the transmission fluid and diff oil get flushed as Inspection II technically requires. However, there have been so many horror stories about dealers simply skipping the majority of work required in Inspection II; any ideas for ways to ensure it all gets done? Thanks! |

Start with the inspection II checklist in the service manual (also found here on this board) and add your extra requests. Make a list as you indicated and go over it with the SA in advance. Expect to pay for services over & above the standard items if you dont have an obvious problem/noise to otherwise justify the work. I just put together my parts list for the service which I wil hand off to the SA in advance ( like the replacement plugs for diff/ tranny etc.)
Tell them you want the checklist completed and returned to you along with the valve worksheet. Defintely have them check the intake cam bolts ("vanos bolts") when they have the head apart. When in doubt, get the service manager on the phone in advnace and tell him your concerns. As others suggest, a case of beer in the trunk goes a long way towards goodwill. |

The only way to ensure that it's done is if you DO IT YOURSELF. The majority of Inspection II items are fairly easy to do except the valve adjustment. And when they do the valve adjustment they'll see the VANOS cam bolts.

High Pressure cooling line for the Power Steering. It will start weeping before it fails, somewhat common.

It fails very slowly from what I hear. Haven't heard of any failing catastrophically.

They cannot see the VANOS cam bolts by just doing the Inspection II. Extra work has to be done to access the bolts.

Chances are that if you've made it to inspectionII, you won't have a cam bolt issue.

Thanks for the input, all!
I've heard the beer suggestion a couple places -- are the techs actually allowed to drink while working on customer cars?! Would be awesome, but surprising. I definitely want to treat them any way I can (probably a cash tip too). I'm still under the extended maint. warranty, so with the work being pretty much free and myself unqualified to do the valve adjustment specifically, I'm hoping to make the most of its time at the dealer . I should have gotten some magnetic drain plugs for the tranny and diff (instead of just the oil pan), and asked for them to return the originals, thereby guaranteeing the fluid changes. |

Despite our issues with some dealerships, if you spend any time in the waiting room at a dealer you realize it goes both ways. Man, some of the arrogant entitled customers they have to deal with! And it's not easy telling people who are out of warranty, and who continued to drive the car with no coolant that it's going to cost them a load of cash (at which point the idiot who drove w/o the coolant takes it out on the SA). Yep, been there for those. So the beer is generally appreciated when viewed in contrast, and makes our requests for adjustment worksheets seem okay and not picky, it's all about perception. (Beer makes everything better!!!! ) Quote:

Thanks for the background on the beer; makes a lot of sense. I do go out of my way to treat customer service folks (call center people too) like the human beings they are, since it's so tough to imagine dealing with disrespectfully irrational people all day... |

Freakin' awesome! Iphone, NP, I agree, always pays to look at things through other's eyes. A nice 12 pack (I usually go for a sampler, since that way everyone is happy) costs very little, but as they say, it's the thought that counts. |

So much misinformation from them, though. My SA (new to me, but one of the more experienced ones with supposedly a lot of knowledge about rarer cars like the Z8) insisted that the tranny and diff drain plugs were not one-time use, but I told him I knew that they were and had marked mine to ensure they are replaced. At least they did look it up and confirm they are one-time use. Similar things like telling me the keys "don't have a battery in them, and are recharged by the ignition" -- yes, they are recharged, but obviously there has to be a battery to recharge (and mine are pretty toast). I was going to have them pull the oil pan off to tighten and loc-tite the oil pump nut just in case it was loosened by my spin on the track in gear, but they quoted 5.7 hours of labor ($1281 total), and so I'm currently planning on risking it. The car did drive another entire day on the track and has seen redline plenty of times without failure yet. One of the more frustrating things is that I'll probably have to swap my old brake pads back (from before the track event, which had too little left to do the event) in order to get them to do the swap--even though the front rotors are below spec, and my measurement of the rear rotors suggests they are as well (they claim they are still above). Oh well, another loaner car to beat on for next time! (got a nice 335i hardtop convertible with M Sport package this time--the steering wheel is /almost/ as nice as the Z4M's!) I did do the 12-pack sampler gifting with a $50 bill inside . They have one of the shop foremans assigned to the work, which is really nice. Last edited by iPhoneEngineer; 08-02-2012 at 06:05 PM.. |
