    Thanks for the compliment. It's also my profession :grin

    Batteries are bad for the environment if they contain Lead, Mercury and/or Cadmium as some of these elements are toxic and non-recyclable. Not all batteries are the same. Tesla's battery pack is quite good with its NCA chemistry of Lithium battery. They don't use any Lead, Mercury and Cadmium...
  4. Bosch ABS Hydraulic Pump Rebuild or Replacement?

    W126 S,SE,SEC,SEL,SD,SDL Class
    Thanks guys. The attached ABS literature was very enlightening, and Kent's vids are helpful to an extent but wasn't able to find any vids covering the ABS pump in particular. Thinking outside the box, I lightly tapped the top of the ABS pump with a hammer and the caliper released! Perhaps a...
  5. Classic ?

    W126 S,SE,SEC,SEL,SD,SDL Class
    If going by the books, the CA DMV defines a historical car as being at least 25 years old (MI DMV is at least 26). The AACA defines a vehicle over 25 years old as classic, while Hagerty calls 1979 or older to be antique or classic, although it considers some 80s and 90s cars as collectible. In...
  6. Bosch ABS Hydraulic Pump Rebuild or Replacement?

    W126 S,SE,SEC,SEL,SD,SDL Class
    Greetings Fellow W126ers. I'm almost certain my ABS Hydraulic Pump unit is bad on my '85 500SEL. It started out with smoke coming from the driver front rotor due to sticking calipers :eek. I'm able to step on the brakes and reproduce this sticking caliper every time, even with the engine off...
  7. Cloud of smoke after sudden stop in 1986 560SEC

    W126 S,SE,SEC,SEL,SD,SDL Class
    Better late than never. I had a similar issue where my '85 500SEL would generate a very thick cloud of smoke behind the car like a James Bond smoke screen. This would happen only during a long deceleration while exiting a highway or when going downhill, and sometimes in city driving. IIRC the...

    Ah gotcha. Must be good stuff! In my household we say frunk to avoid confusion with the trunk, otherwise my wife drives me crazy asking me to help bring in the groceries 😁
  10. Smoke test question

    W126 S,SE,SEC,SEL,SD,SDL Class
    See attached. I took one of your photos and placed an arrow showing the adjustment hole. BTW I wouldn't mess with it unless you HAVE to. Best of luck tackling your vac issues.

    It looks like you're only talking about 1 type of upstream in generating electricity. (On a side note, end of downstream is the use of the EV, and you can read my previous posts on it regarding inefficiencies compared to gas cars.) The example you gave here looks like a fossil-fuel-combined...
  12. Problem with Hot Start 380 SE

    W126 S,SE,SEC,SEL,SD,SDL Class
    I know you already had the ICV/ICU replaced. If you can validate that the replacement parts are indeed working by measuring voltages, that may give a peace of mind. Flute sound? Then a vacuum leak is suspect, and can cause high idle. Try performing a smoke test to determine where the leak is...

    Lithium batteries weren't great for the longest time up until end of the 90's, depending on the battery chemistry (yes there are many types!). Tesla uses NCA chemistry. Engineering datasheet for the lithium NCA battery is readily available if people are concerned with longevity and want to get...

    While mentioning the 2nd law of thermodynamics, we should also mention the 1st law where energy cannot be created or destroyed. So you're accurate in that 'electricity has to come from somewhere'. However the 2nd law actually illustrates why BEVs are better than gasoline-powered cars and here's...
  15. Problem with Hot Start 380 SE

    W126 S,SE,SEC,SEL,SD,SDL Class
    Sounds like multiple things going on.... High idling: Idle Control Valve / Idle Control Unit or vacuum leaks. Do a smoke test for look for leaks. Quickly apply 12V to the ICV to ensure it clicks. Measure the voltage at the ICV connector while the engine is running to test the ICU (it should be...
  16. Smoke test question

    W126 S,SE,SEC,SEL,SD,SDL Class
    I did a smoke test on my 500SEL awhile back and only saw smoke coming out of the lambda (on/off ratio) adjustment hole. You guys see the same? I left mine alone as it passed smog anyway...in California where the tests are strictest!

    Nice! It's been ages but I remember the fun of burning EPROMs, testing out different fuel mapping, swapping MAFs and injectors, logging data and measuring power gains (or losses if you overstep the mark :grin ). I went a step ahead and kept a running laptop in the car to log data, store it and...

    Hi IWantedaJag, back in late 90's I was already uploading/downloading ECU information, fuel maps, etc. between my laptop and my Nissan 240sx for tuning purposes, and retrieving information wirelessly. So you are right, it's nothing new. However, with respect, I don't think it's really about who...

    Speaking of negativity, I noticed people are still latching on the news that Elon received $4.7 Billion in government handout. They need to understand something... NASA and US Military were paying the ULA about $460 Million per rocket launch using RD-180 engines which is Russian, so as a...

    Over-the-air updates keep adding new features and improving existing ones, making Tesla the only example of a car that gets better as it gets older. With its battery life cycle rated for 90% capacity after 160k miles and 80% after 500k miles, it would outlast a gas car if considering long-term...
