How was the issue been resolved?

I am not an engineer but just with the indicator failing, I'd prefer to try to make it work!

So either I haven't cleaned I properly or I was wondering if the connectors coming from the car into the SAM may also need a clean. hmm

or SAM is deceased ..... ;-)

That's what mine was doing too before I replaced the SAM

Thanks.

You think for the issue I have had, it is worth sending to the UK for service ?

Get in contact with Tony (tune4performance) , and ask of the options for repair/software-upgrade of the SAM unit.
He did a few for me , very good and no problems with them.

So here's the thing. I used isopropyl alcohol, cleaned the SAM as much as I could, left it a day and reinstalled it. Its all working except the left indicator will not stop flashing - any ideas ?
I would also like to know whether in your views I should buy a spare SAM to keep incase of emergency.

Thanks.

......
If I just take my car straight to Mercedes their quote for a new sam unit installed is $3000 Australian.

Ouch! That's taking the p***. It'd take half an hour at the most to physically fit ....... no idea how long STAR takes, but it can't be that long.

a new SAM fitted & programmed by Mercedes cost me £600 a few years ago so your guess of $1200 probably isn't that far off.

Well get this > my estimate is based on importing it from Smart stuff (https://www.smart-stuff.parts/452-ro...ol/450-452-sam), installing it myself and getting Mercedes to program it.

Thanks. Well the type of rework is hard to do. In that there are no smart specialists here in Australia. So I can go to a generic company that handles merc or automotive modules. Having spoken to them, they said they are happy to 'service' it but cannot guarantee a fix since they do not smart specific tests. This they have quoted $500 which remains a gamble. A new SAM unit plus programming here would cost me probably $1200 or so.

Bathing it , submerging it even in ISO, isn't gonna do jack **** if the copper is corroding … it'll need rework , replacement of components and track bypassing …. IF you're lucky.!

Hey guys and gals.

I have recently discovered water damage on my roadster. I have pulled the SAM unit out and it has corrosive damage. There is a guy locally who baths these I assume in isopropyl alcohol. I am wondering if that is my best chance to get it working

Water has a nasty effect on copper, (once it gets a grip) and can kill the board completely.

Conformal coating (sprayed on, both sides) is a reasonable defence against moisture (on good componenture (just made that word up) will not do it any harm at all) , but it's not a 100% defence. For a start it will not help at connectertage (just made that up too)

Who is THE guy ? More details required
