I think I damaged something......

[RhodieBill]

After doing a quick oil and filters, Oil/Air/Pollen. I gave the car a good clean including the Mats etc.

Whilst doing this I was constantly opening and closing doors when suddenly I noticed the Soft-close stopped working - and the Boot wouldn't open other than with the Key. Not to mention the Central Locking and Rear Headrest Drop-down being inoperative! (Been perfectly fine before and nice and quick)!

Anyway, sussed that Fuse "62" had blown - big deal, fuses blow sometimes.

So to cut a long story short I ended up blowing £ Fuses eventually. (All the 20amp Fuses I had except one).

The only other thing I noticed is that when I removed the Driver's Mat I banged a little white Tube under the Seat, but it still looks all connected to a connection in the Frame joining a similar black Pipe. No damage is obvious.

Anyway, I got fed up and have left it with the Fuse "62" removed, (last one I have) and locked it up with the Key but armed the Alarm with the Fob. (Lights flashed 3 times).

Have I basically $*&"*^ up the Pump or is it something else.

To be honest I'm starting to feel I should have kept a perfectly good CLK320 instead of buying this heap!!!

Said Fuses!

Is deffinetly a big short circuit outhere. to blown a 20 amp fuse it needs to be short tyo ground directly. Very unlikely to be water in one of modules....

It only blows if I try to use the Central Locking or open the Boot etc.

If I replace the Fuse the Soft-Close on a Door or the Boot will work once, pull it down and go click.

But if I try to use the C/L or open the Boot it blows.

It was working perfectly moments before this happened...???

I've heard that leaving it overnight it resets itself or something. Anyway, that is what Im doing tonight. Obviously if it still doesn't work tomorrow I'll just have to live with it because I sure as hell not throwing money at it for something else to go wrong!!

Looks like you could have shorted the wiring below the seat it's quite tight around the frame had a 20 AMP fuse blow that controlled the seat motors. Cut a few cable ties that were too tight insulated the frame and put new cable ties not so tight.

Hi. But if that was the case the Fuse would blow as soon as you put a new one in.

In my case just as long as you don't use the C/L or try to Open the Boot remotely the Fuse is fine.
Surely there are no Wires under the Seat that have anything to do with the Central Locking...???

Tough luck Rhodibill, Cars are made of lots of interconnected bits and when you break one, lots of things stop working. I understand your frustration but to go from vigorous cleaning to thinking your car is a heap, is something of a leap.

I hope you get it sorted and that it doesn't cost too much. Perhaps just stick to light dusting in future.

I'm not sure what's all fused on your fuse 62 but on my C class it only happened when using the seat motors. You said you were opening and closing the doors have a look at the wiring harness between the door and the body and see if some wires have been trapped or insulation broken in the flexible section.
Edit.
Had a look around the wiring diagrams and found the fuse 62 controls unsurprisingly the PSE module and pump. Just check that "pipe" you moved isn't insulation and doesn't contain a soldered joint in the harness.

 

[Ken_R]

Does the Central Locking also lock the Boot? I'm assuming so. I'd be looking at the Boot lock. Water ingress, etc.

Can you pull the wires off the Boot Lock? That's where I'd start. If you can't get to the wiring connections, then Hair Dryer! Get some warmth into the assembly and try again.

 

[Flyinspanner]

Wonder if it is wiring at the door hinge, c/l and boot release are both on drivers door?
May have just been the day wires decided to break?

Hi. Yes, Fuse #62 is Solely for the C/L Pump. Apparently the Fuse usually blows to protect the Pump. I think the Pump is only designed to run for short periods, (a bit like a Starter Motor) as it is totally encased and insulated, so I presume it can overheat very quickly...??? It usually goes into "Protect Mode" if there is a leak in the system and it pumps continuously to take up the slack so to speak causing it to overheat and protect itself by blowing the fuse.

Maybe I just "overstressed" it..... Anyway, that is what I am hoping. (But secretly I fear the Pump is kaput - more in line with my luck).
If it is, well so be it because I refuse to pay the price that they are new!!!!

I can't do anything today as it is blowing a hooley outside! I'll just leave the fuse out for now and use the key - trouble is getting in the fuel flap to put petrol in as that is locked along with the Boot. (At least I can get in the Boot with the key).

Thanks to all with the suggestions etc.... Appreciated.

Would a fault code reader show a logged fault/history giving any more detail ?

More than likely, although nothing is shown on my little Bluetooth one - but there again it only a 5.99 jobby linked up to a Torque App on my cellphone.

But I'm meeting up with "Wearsafoxhat" tomorrow at the Hampshire Bowman and he is bringing his Diagnostic Scanner to see if we can pinpoint my misfire aswell.

That is why I'm saving my last 20amp Fuse to plug in when he does the Scan in the hope it will come up with something.

I have the Fault Code Explanations:




So fingers crossed..

 

[Wighty]

Good luck tomorrow then . I don't suppose retracing your cleaning route around the car and looking at what you may have "knocked" or got wet may help ?

 

[ajlsl600]

can you not remove the plug to pse , put fuse in and see wot happens. if blows check from pump back .nothin happens turn off .plug pump try again fuse blows you have an answer

 

[Wearsafoxhat]

Shall I raid my 20Amp fuse drawer too. : )
See you tomorrow.

You should swap the fuses for biscuits buddy

I did.... But I couldn't see that I had done any damage to the Pipes under the Seat. Also I put the Lumber on the Seats back to Zero as they were on 2 and as I did this I could hear the air escape at the Control - which is supposed to do. I'm presuming if I had damaged the Pipe between the Control and the Bladder in the Seat surely the Air would have escaped before I had turned the Control to Zero, if you see what I mean.... Anyway, that's my thinking.

I've just taken a photo of the Control and the White Pipe to which I am referring.. (And yes I know I didn't tuck the Mats down under the Seat properly). No damage or hanging off.





But you can see how by removing only the Rubber Mat how I knocked the White PIpe as I lifted it up to get it up from under the Seat.

Oh, and I don't use a Pressure Washer on the car, only a Hose with a gentle Spray to Rinse off the Soap.

Thanks. But I have already ascertained that it is the PSE Pump that blows the Fuse as on Fuse #62 it is only for the PSE Pump.

Yes please - Bugger the biscuits...lol. But it'll definitely be something....

see that , if you had a leak ,think pump would continue to run until it decided to shut down or "blow" the fuse to protect pump ?
