Rockauto RCM's
Rockauto RCM's
I have been inside my Relay Control Module more times than I want to admit. Still works fine but I wanted a spare. I have had some really weird cars in the past and don't enjoy getting stranded.
Took the plunge and ordered one from Rockauto figuring it would be a Chinese knockoff but would work as a spare. Part # 1R2032 (Airtex). I paid 131.37 shipped, using an online Rockauto discount code saved me six bucks.
It arrived today and much to my surprise it is OEM! I really thought it would be some offbrand. Exact same markings as my original with just a different date code. All else was the same, even came loaded with all fuses and has the Mercedes star on it. I was shocked. Plugged it in and off I go. Car ran fine, auto trans seemed to shift even better???
Anyway just thought I'd post because I have seen this exact module selling for $500+ and there is no difference at all.

Re: Rockauto RCM's
Funny you should bring this up.
I'm a big fan of RockAuto. It's a local company from my home state.
I broke the tether on my gascap recently. Found 4 items at RockAuto and picked Gates. All 4 were +/-$3.
It came yesterday. It is a bagged original OEM Mercedes Benz part. In the correct P/N Gates box.
Imagine my surprise!
And OEM M/B was not one of the options.

Re: Rockauto RCM's
Well, let's see. I bought the exact replacement relays for $3.10 each. There are a few diodes (50 cents each) on the board as well, and it's in a plastic case with some heavy molex connectors on it.
They should be able to build them in 10,000 piece lots for under $20 each. Add 100% markup for about three levels of resellers and shipping from overseas - and $125 sounds about right....

I plan on keeping my xfire for the long haul and don't mind hoarding electronic parts. It's just crazy the way parts prices vary for these cars. I was shopping for a rear O2 sensor and the prices varied from 100 to 500 bucks for the same part. I got both rear Bosch O2 sensors for less than 90 bucks total. amazing, just shows that if you do your homework there are big savings to be had.
This is the first time I've used Rockauto but will again.
My reason for posting is that some members are hesitant to resolder their RCM. They don't have the equipment or the skills. In actuality when resoldering you are soldering to the frame of the relay which acts as a heat sink and that is probably why some resolders fail. I think for a buck and a quarter it is a fair deal.

Re: Rockauto RCM's
$15 to repair and perform the Me So Horny Mod is even fairer!
($20 if relay needs replacing)
Saves ya $110!

Re: Rockauto RCM's
Just be aware that these will fail just like the OEMs. No matter what mfg is stamped on the box, the boards all come from a single source (Poland?).
They all still use the same solder. It's already happened to a couple of members who bought brand spanking new RCMs.
Some have lasted less then a year. Better off getting them fixed IMO.
As often as these fail, I'm sure there's a stockpile of them from the dealers.
Wouldn't surprise me that someone is refurbishing these and repackaging them for resale!
I would imagine that with the right silver solder, the points would sustain positive contact and stay cool enough not to cause havoc with the relays and therefore make the boards bulletproof. Have not heard if any of the boards tighed1 has repaired ever coming back for re-repair.
But that's just my thoughts.
