You know what happens when one cranks on the 4×4 knob instead of the radio? Nothing. The 4×4 knob has more resistance and the mind knows.

Hmm I’m not sure how well the fuel mist at the throttle body would clean the backs of intake valves either. Presumably intake-runner mount port injectors are the best at hitting the backs of valves with fuel mist before it gets super atomized and lost in the rush of air into the cylinder. I’d love to hear an actual powertrain engineer chime in on the matter.

I’ve not seen any 9-speed issues, yet. We’ve done some ATF drain and fills (which concern me, honestly), but I’m fairly sure we haven’t swapped any of them. Compared to my early days of doing an early 00s V6 AT every other week, this “problem” doesn’t really seem to be one, at this point.

They say letting the engine rev for periods of time and lots of highway driving helps prevent this…but then again, they say nothing will. The revs make no difference since they cleaning is simply NOT happening by the fuel.

DENSO, the world’s second largest mobility supplier had planned to invest USD 100 million over a four-year period in startup companies around the world to advance mobility providing software-based solutions focused on electrification, automated driving, and connectivity.

The global automotive fuel rail market geographically is segmented as North America, Eastern Europe, Western Europe, Latin America, Asia-Pacific excluding Japan, Japan, and Middle East & Africa. North America and Europe hold a significant market share of automotive fuel rail market owing to increased demand for automobiles coupled with the presence of companies with huge production capacity. Furthermore, the increase in R & D activities related to aerospace and automobiles, wherein automotive fuel rail reduce vehicle’s weight; aids in boosting the growth of automotive fuel rail market in the region. The market in the APEJ region is more inclined towards growing demand for automotive fuel rail because of the increasing demand for vehicles with higher fuel efficiency in countries such as China, India, and South Korea.

To repair an injector it must be dismantled, cleaned precisely and then re-assembled in an air-conditioned, pressurised, clean room as even the smallest piece of dirt can contaminate a fuel injector’s nozzle which could cause it to stick in the open position. If this happens, the injector will leak fuel into the cylinder causing expensive damage to the engine and a furrowed brow of the customer when they are presented with the final bill.

My wife has owned a 2013 Freelander 2 SD4 GS from new. Recently the dash displayed: “gearbox fault, traction reduced”. We had the car checked and serviced in our local garage but they could find no fault with the drive. Looking on-line at this fault, a considerable number of other people are experiencing the same. One contributor recommended unplugging the sensor from the Haldex and re-attaching it, which I did and it cleared the fault. However, it seems to return after a short while. Whilst not sure, I feel fairly certain that the fault is electrical and is tied to the Haldex. Are there any ways of effecting a more permanent fix as my wife feels a bit uneasy driving a vehicle when it displays a fault?. It is also surprising that Land Rover has not resolved the issue, or at least advised on it?

Reminds me of a problem I had with a gear shifter cable snapping on my bike… this got me out of low range:

Ultrasonic welding requires physical contact of the material and ultrasonic welding tool, generating unwelcome particles, limiting the minimum thickness of the individual copper elements, and requiring frequent adjustment that shuts down production.
