No - that's the fan controller & it must be OK if your SDAS activation got the fan to full speed. It's either the temp sensor in a pipe that I gave Patrick the diagram for or there is an aircon sensor at the bottom of the radiator if memory serves me correctly.

skittles

agreed glyn. but this sensor i cannot find at any of the online stores. they all look the same with the one i had ordered.

anyways, hopefully the dealer gives me good stuff and not say that my fan is busted.

BTW karo great night huh? lmao.

i got my kit from blackstone. so ill send them my tranny fluid samples ASAP.

ill keep you posted on monday.

You damn hoodlums terrorizing 101 freeway loool

I still gotta hit up a race with Ming. Just to see what the 203 vs 204 can do. Too bad in the end Armen got caught. He was the most behaved from all. The turbo charity is growing. I got 90 bucks from client today lool. Including the wheel money that's 1600 left to go then we can see what the m272 can do on boost.

If you take off your vinyl roof I think it'll look cleaner (you are right).

Here is Patrick's report. Are those guys stupid? Remember we did a brake fluid flush and it was green. We got every dirt out of there and they want to do a flush again? Didn't you do a Tranny flush?

Typical dealership scam artists

Tell me about it. The funny thing is we probably did the Brake Fluid flush couple of months ago and Patrick did the tranny flush maybe 10k miles ago.

I think they did find the overheating problem just didn't want to mess with it or maybe since we tested the fan with SDAS maybe that fixed it?

Patrick is your car still overheating?

Wouldn’t call them “stupid.” They’re just looking for another easy mark.

Seriously doubt that Mr. Cruz tested the brake fluid for its absorbed copper and moisture content.
Suspect it’s far more likely Mr. Acevedo merely glanced at his calendar.

Odd that as part of their “world class inspection,” there is apparently no reference to the cause of OP’s contaminated/burnt ATF or alleged overheating. Incidentally, Fletcher Jones in Newport Beach – hardly a favela – charged far less to perform identical maintenance tasks on mom’s leased ‘07.

KY available in their gift shop too. :y

loooooool

Another "certified technician" from the funny farm.

Customer states vehicle overheating!!!

Action: Ignore the customer - zero comment on overheating

Recommendation: Two scam flushes & some tyres on what seems otherwise a very well maintained vehicle.

Oh! & a light bulb that needs to be diagnosed! Find another dealer that turns on their hearing aid!

lmao. i just got home from beverly hills karo. was at mins the whole weekend. well we all know now its a scam. car still behaves the exact same way. overheats to 96 then drops to 90. you know the story. then did the recall thing without telling me though. but it said on the report that i notified them. lol.

after i swap my suspension this week i will double check how i installed the thermostat. also karo is right. we did the brake flush last month, and i did the tranny and coolant 10k miles ago. its possible they are right that my tranny fluid is burnt. my tranny oil is goldish remember. but i dont get any abnormal behavior at all. just the temp. back to the drawing board..

W203E35

Your mom is gonna kick your ***. You didn't go home at all? lool

You didn't pay anything out of your pocket right? I bet you they didn't even do a road test. Those idiots probably saw the fan spinning and thought it works.

Remember the sensor you got? Try looking for it at getmercedesparts.com since the one you got is longer. Maybe that sensor might be the problem. Fan is working fine.

skittles

nope dint go home. lol. its all good.

anyway. that link you has some illustrations and it seems like the part that i had that you saw, it goes under the radiator reservoir. im still trying to search what this part is exactly. i read somewhere its called an ECT. i took it off before and it looks like it was made out of copper and coolant spilled out where it came from. this is what glyn also recommended i replace first. ill pull it off tom and take a pic. maybe you can tell better.

skittles

i think i found it. search for this part number at the link:

000 542 51 18

http://www.rmeuropean.com/search.aspx?keyword=

I'm pretty sure that's the part Glyn recommended me to replace first. do you think its gonna work?

Glyn M Ruck

Just to prevent confusion:

The coolant temperature sensor unit part number is indeed 000 542 51 18 according to my records. The description is wrong on the rmeuropean website. It does not mount on the crankcase on an M271 - it might on other engines.

It is sensor 146 in this diagram





The sensor in the bottom of the surge tank which looks similar is the coolant level sensor - No 190 in this diagram



I don't know if this will fix the problem but, much as I hate throwing parts at things until properly diagnosed, we are running out of options & the sensor is cheap. If it is faulty it will also improve your mixture control because this also provides the ECU with engine temperature data. At least your problem is not running cold which would cause the ECU to richen mixture & chew gas.

Patrick - to backtrack & cover all bases. Am I correct in saying that the fan goes to approx full speed if you engage the aircon, or sometimes when you engage the aircon? After this our next step has to be to check the aircon sensor. Am I correct in saying that your highest recorded temperature has been over 100 deg celcius?

Good luck

Glyn M Ruck

Are you still meddling in Patrick's sex life - LOL

skittles

it never goes to full speed. not even with the a/c on. and the highest recorded temp was 104 and thats when i jumped out of the car for 10 mins to buy something, then when i started the car it was already at 104 then started to drop when started. its really unusual behavior. something in my car is forgetting to tell its lungs to turn on. as of now we are all clueless. should i double check the thermostat? maybe i got a faulty one or installed wrong?

skittles

THIS IS FROM A DIFF FORUM WHERE THEY SOLVED THE PROBLEM

i just read that now. is this what we tried to do Karo?

Glyn M Ruck

OK so it went to 104 in heat soak condition - that's not too bad.

I think the thrmostat is OK - change that temp sensor.

One quick question that is way out there. It is not possible that someone has put neat coolant into this car without diluting it 50% with deionised water, is it?

skittles

i really don't think so. i think i'm the only one that touched the coolant on my car. although on my flush i used an MB alternate coolant. i think it was ZEREX something. could htis be the problem?

also just called my local dealer. the sensor is 16 bucks. i think ill just get it there. shipping is like 10 usd id rather pay the tax here than the shipping.
while im at it should i get a gallon of mb coolant?

W203E35

loool Patrick is like a used and abused tire. Although his price is like a brand new one

Honestly I don't think STAR will fix your problem. Your fan kicks in different times. Sometimes at 90 sometimes at 100. So I don't think it's the setting but a sensor. Sounds to me like a faulty sensor is giving bad readings.

Glyn M Ruck

No Zerex is OK as long as the concentration is 50/50%

I'm clutching at straws - 100% neat coolant will push up temperature because it does not have the same heat transfer capability as water. Just thought someone might have filled with neat coolant by mistake.

Do the sensor - 1 thing at a time or we will never win.

skittles

ok. im leaving now to go to the dealer. be back in 30ish mins.

W203E35

Everytime I see this Chuck Norris thing I remember the story you told me. How you went to audition as an extra for Walker Texas Ranger and you saw Chuck Norris in the changing room and he invited you in and you guys changed together. Do you guys still keep in contact?

skittles

lmfao! doo doo head! shhhhh... dont tell.

and everytime i see that judo thing i remember you trying those moves in bed with granny. but she's not flexible enough..

damn traffic man. 0 visibility on the fwy.

got the part ready. gonna let the car cool down before i install it. also left the radiator cap open so that not so much coolant will spill when i swap the sensor.

W203E35

You're the Granny dude, that's why you always get hurt when I make sweet love to you. You call me next morning threatening to sue me cause I hurt your "back". I told you not to mess with the Armenian Salami bro loool
