In addition to what gigondaz mentioned, late 90s to early 00s Mercedes have the transmission computer under the shifter and you have to take care to not get any liquids dripping down past the shifter or you are on the hook for a $1000 TCM.

But on modern vehicles with electronic modules, CAN-bus data bus systems, connectors and sensors everywhere, power-washing door jambs and other areas (EXCEPT the exterior paintwork) is a NO NO for me. In many vehicles, its main ECU could be located inside the front kickpanel (eg: many Mitsubishis). If water seeps in, and touches EVEN ONE contact pin...the ECU is fried. I've seen this happen.



I do Audis very regularly as my company services the local Audi dealership.

On Audis, especially the top-end models (Q7, A6, A8), there's lots of buttons on the centre console.

Audi has already alerted their dealers (TSBulletin)that any liquid spilling onto these areas might slowly migrate into the underneath and could damage the control units UNDER the centre console. The warranty will not cover these damages. During a heavy downpour, even water dripping from a wet umbrella, or a few drops of coffee...if it falls onto the MMI switches and through their gaps, could cause problems. CD player wd not operate, AC controls freeze etc etc.

Then there are some serious defects in how these vehicles are built and designed. Every electronic connector and component in a vehicle is supposed to be watertight. Take some electrical connectors apart, you see the rubber "grooves" that circumference the plastic before the eletrical pins ? Those are there to prevent water and liquids from getting in. In theory, you're supposed to be able to fully submerge a vehicle in water, take it out, let it dry out, and none of the electronics are supposed to be damaged (again, that's in in theory).
 
sacdetailing i know exactly what videos your talking about.....the dude is power washing the jambs on a grey bentley and the other guy polishes then clays a white caddy...
 
doing door jams with a PW is different, than what i saw the guy in the video do. he actually PW's inside the trunk and inside the interior, not just the jams. i've been using a PW on jams for over a decade and make sure to take care and aim the stream out. sure a little drips into the cabin, but no more than when i get in soaking wet when i run across a parking lot at the mall on a rainy day. common sense and care goes a long way. hell i wont even use my steamer on the dash of cars for fear of getting water behind a switch, gauge or panel. i err toward caution, especially when doing a car that costs more than my house. rather spend a few minutes and some elbow grease to clean a dash than to spend the next month working to pay for a part on a bently or AM
 
Aim in direction where you want water to go with PW if you use on door sills. As I read this thread I am looking at youtube and expert villiage, when i see this I wonder how these people dont go out of business making mistake or risky move on customer car... but luck is that person doing it right gets bad luck and has to pay consequence, careless people may have better luck ..
