李先生，你好: 我，王曉鵬，也是在加州，自從在youtube看了你自己動手修理保養車子後，自己也想試試動手修理。 我有個 2003年的 SL55 ，最近一次去維修廠，維修人告訴我車子 left and right lower control arm bushings were broken ，我一直沒有處理，想請教您，如果自己動手更換 either bushings or 整個 control arm ，不知難度如何？及如何更換呢？謝謝！

李叔叔，您好。想咨询一下您能查到x166 2013年Airmatic Suspension的数据吗。最近想做一下Calibration但是需要一些angle的数据但是网络上找很久没有找到。望回复。

Hello Sir, Save you done m278 throttle body coding and if so how? Thank you. San

李叔你好，又来麻烦您了。 还是关于我看上的那部2014年E350的一个问题，目前还没有入手，因为找到一部合适的老车子很难，不过这个车子整体状态还可以，除了上次我问您的关于变速箱周围的油渍问题，还有一个关于下摆臂的问题，这个车子才跑了4万9千miles，下摆臂衬套已经这样了，您觉得正常吗？？ 是因为曾经的车主开车比较猛还是因为时间久了，橡胶件老化？？ 谢谢您

李叔您好，能麻烦你传一下w204 C300 刹车片的WIS吗？ 另外，我看不同视频，是需要把刹车盘，刹车卡钳也要卸下来一并清理，并加硅脂润滑剂吗？ 谢谢！ 另外感谢您之前，对于变速箱油和差速器油的建议和帮助，我更换了后差速器油，发现非常干净，确实是终生免保养，所以我前差速器就没有更换。变速箱油也更换了，67k英里，吸铁石的金属碎屑很少，放出来的旧油也很清澈，总体感觉新买的C300机械车况很不错。

Senior leigh how do i get wis ? Thanku

Hello Senior Leigh, I used your M278 sparkplug video to begin the process of my valve cover gasket repair, so thank you very much. I've noticed you have provided documents to help people with their jobs. With the coils and plugs removed, I am not 100% sure what to do next. Can you tell me how I can

Oh well I never have such a bad luck on my wife 2010 C350 4M W204. To make this short the driver seat caught a duster and I took the seat cushion off. And notice that the short cable around 63cm was twisted and broken. MS said it cost $ 3,000.00 for the whole base and that what they sell no kidding

李哥您好，我是來自台灣的朋友，我的車子是2014年E400(W212)車系， 最近幾次發現，腳踏的手剎車，越來越不緊，我想請教您 可以自行調整緊度嗎? 補充:我會自行更換剎車皮的經驗，有更換成功過。 不好意思，謝謝李哥的協助，很喜歡看你分享保養車子，非常專業，謝謝

Hi Sr, Leigh Any plans documenting the replacement of PCV valve for M276? My truck has about 88,000 miles and is a 2015, so probably would be a good idea to replace it. I think is a bit more complicated than for M272, which I already did for my other car, but for M276 I don't see good tutorials.

Hello Sir. How are you ? I have a question since this Nissan don't really tell me do I need Tranmission flush or replace. It just say inspect. But there is no dipstick to check. I believe the dealership have one that cost over $ 600 to mearsure the fluid level. I was wonder is that ok if I drain the

你好，李叔叔， 请问一下，您可以介绍一下或者发一个链接关于所有维修W212小改款后的E350的工具吗？ 因为我也考虑自己修车，但是不知道应该买什么工具 ？？？ 比如oil change,换火花塞，换变速箱油，换engine air filter, cabin air filter所需要的工具, 谢谢

李sir, 您好，这个网站太好了，从Boston来的感谢！

Hi 老李，感謝您的視頻分享，參考您的視頻後，近期計畫自己動手更換變速箱油。 我的車底盤代號是W204，搭載722.9變速箱。請問施作更換變速箱油之前，我有需要等待變速箱油溫冷卻才能卸下舊油嗎？ 謝謝。

李SIR你好 想請教08年底出廠W164 ML320CDI 里程7萬 目前有發現漏油 但不嚴重 店家說是進氣管與柴油管需要更換 目前爬文大部分指向機油散熱器油封墊 請問你的看法呢 謝謝 下方岐管進氣修理包需要一起更換嗎

Can you help me with vin number: 4JG1660571A806938. gle 350 2016 Transmission 722906 08 296494 How many quarts do i need to do the transmission fluid without torque converter? according to wis, adding 6 quarts then 2 more at end? The dealer says 5 1/2 quarts.

2010 and 2012 C350 are they using the same Power Steering Fluid. When I need to change them and some say is life time just top it up if need ( I really don't believe is life time) and under the manual it say Chevron Texaco PSF 9109 and it look like it hard to find. So site say Mercedes 2008 - 2010

The WIS of the firing order can help us to identify the number of the cylinder.
