    C205 C63 Replica (Don’t Hate)

    I agree with both sides of the argument, you've both got valid points. ME personally, I wouldn't spend money making my car a replica of something, I always buy older cars so I usually always buy the best I can which is usually the "best" variant of a particular model. They're sheds in most...

    Coolant fan not working C32 AMG

    🤣😂😁 Right we have a conclusion.. Basically each time I fitted a part I didn't want to take it for a drive because of the potential overheating issue so instead used the a/c function as a way to determine if the fan was working or not... The problem is I now know that the A/C isn't working...

    Coolant fan not working C32 AMG

    Bought a creator c502 scanner, very good little unit. Made specifically for MB's and goes through the whole system to find faults, quite impressed with it for the price point. Found faults that all point towards my esp system, but not sure if some of them are due to the battery being...

    Coolant fan not working C32 AMG

    Also I didn't realise a normal obd2 reader would work on a merc, I thought it would be star only. Connects to the ECU fine but can't find any current or stored codes... I thought a code would have been stored tbh.

    Coolant fan not working C32 AMG

    Sorry I thought I'd mentioned it, It would if I had allowed it to. The last time I actually drove it temps were around 100 degrees judging from the coolant warning message gauge (why amgs don't have a standard temp gauge I do not know) and iats were clearly high enough to not engage...

    Coolant fan not working C32 AMG

    Hmmmm, well I assume it is because its the only fan, there is no ac/auxiliary. Being a performance car it should definitely have a dedicated fan that kicks in before 100 degrees or am I missing something?

    Coolant fan not working C32 AMG

    Managed to get it off, pressure switch hasn't made a difference and I also got a new relay p just to completely clear the board of sensors, fuses/relays. I also read about the TSB on the wiring harness adapter so I've fitted one just to future proof me. Looks like it's ECU or a damaged wire...

    AC pressure switch

    Fitted it and still no fan engagement even with air con so pressure switch ruled out.

    AC pressure switch

    Hi guys. In addition to my my coolant fan not turning on thread I'm wondering if anyone can give me a definitive answer regarding the AC pressure switch. Does there function effect the cooling fan turning on during normal cooling operation W/O ac turned on or only when ac is turned on? I'm in...

    Coolant fan not working C32 AMG

    I'm in Nottingham mate. Don't really want to drive it too far with the lack of cooling, at this rate I'll be well into winter so it may be an option though!

    Coolant fan not working C32 AMG

    Couldn't remove the aircon pressure switch, it's seriously seized on and the required force with a breaker bar would 100% damage the condenser, which is looking worse for wear. Does anybody know if the switch definitely effects the fan kicking in for engine cooling or if it just effects it...

    Coolant fan not working C32 AMG

    I did think that but was hoping it wasn't. But after having it on diagnostics and it running the fan at different speeds wouldn't that rule out the ecu/wiring as the program is communicating with the fan through them or not?

    Coolant fan not working C32 AMG

    Nobody has any suggestions? Fwiw if you're ordering a pressure switch there are 2 variants... ask me how I know... the right one should be here tomorrow. I'm assuming they'll be the same as 320's but c32's use the one that has a plastic end that after the thread. Some switches don't have this...

    Coolant fan not working C32 AMG

    Just to update the thread- I've had it put on diagnostics and fan engages at different speeds, so fan, module, wires, fuses must be sound. There are faults within the AC system due to low pressure... I'm thinking ac pressure switch might be the cause, but I thought if there was an issue with...

    Coolant fan not working C32 AMG

    Hi guys I've recently acquired a C32, decided that I wanted to give it a major service as well as changing out the common issues like radiator and IC pump. Burped the system, including partially blocking the intercooler water hose and the fan wont kick in neither will the A/C blow cold air. I...
