If you need the part number for your car, pm me your Vin and I'll see if I can help you out.Thanks Lowmoorfarm - You are correct - I did an internet search (images) and there are two different types.
I cant provide any part numbers as i don't have access to that kind of information.
So its getting more confusing !
I suppose the question is, do both types of K40 Relay module suffer from poor solder connections or is it only the pre facelift ??
The facelift K40 Relay module looks more difficult to take apart, and also appears to have an additional plug in relay on the top. So I am not sure about all this !!
Absolutely not! It will cost a Kidney to replace it. Just have the solder joints re-done @ a fraction of the cost.I have a 230 SLK from 1999 with 130.000km. When do this problems start? Would it be wise to replace the K40 Relay before trouble starts?
Well I have some part numbers: SLK320 (post facelift) A 170 545 03 05, (pre facelift) A 210 540 00 72. From pictures (have the 0305 but not 0072) the fuses look the same but the box shape is different. Used ones seem to go for U$65-U$75,
