Hi, I need to replace the profuse on my C Class C w I read that a 2. Get new one from Mercedes and replace! Don't bypass it, its there for a reason pyro fuse.

Disconnect GROUND brown from battery first and reconnect last, and dont touch live with a spanner once ground is connected back. Why did it blow? Auto-mobile MB Enthusiast. As above why did it blow? If you have been in an accident you will need to replace the unit the fuse plugs into to.The other day a wire shorten under the dashboard behind the glove box.

It looks like I have to take the dashboard out to get at the wires that go through the fire wall. Looking at the dash it is one lump any pointers on how to remove it.

Even the glove box is moulded into it. Hi Grant. Hope you are well. All the best Steve. Grab a torch and have a good look — and smell around and see if you can spot anything. The dash is in 2 halves the upper and lower, just as you say the glove box is moulded into the lower half. There is restricted access under the dash by the hood release, under the plastic under dash cover, but if you have AC expect this to be a little more crowded.

Have a good look in the huge fuse box in the engine compartment to be double sure it cant be put right from in there. I have searched high and low and cannot find even a parts explosion of the dash to assist you in how in all comes apart.

I got a local auto electrician to come over and he spent most of the day fixing the loom, without taking out the dashboard. The fault was a worn wire just behind the light switch on the far right of the dashboard.

The loom passes between two metal plates that support the steering column and they had worn through one of the power wires going to the instrument cluster. This resulted in a hot wire between the fuse board and this point which in turn melted a few critical wires around it before the fuse blew.

The fuse box is actually quite spacious and enabled us to unplug the loom from the back of the fuse board, cut about 10 cable ties behind the dash and pull the loom back to the centre space behind the radio. Replace the wires and re-wrap the loom and refix it. Alas we didnt have time to fix the loom behind the steering column so this is going to be done this Sunday. We also still have the brake lights on all the time. Hi Grant, Be interested to know exactly what part of the loom wore through, I thought most of that under there was cloth wrapped and in some cases even foam jacketed.

Was the wiring disturbed or had its routing been disturbed, ties cut etc. Sounds like it should be noted as a weakness if its as it left the factory. Apologies for the delay in replying but we have just managed to track down all the errors and fix the van this afternoon after 3 days solid.

The initial fault was a small fire under the dashboard which filled the cabin full of smoke. The van was drivable, but the brake lights were always on ans it blew a 7.

In short, I called an auto electrician Brian Dolan who works in West London and we both proceeded to remove as much of the ancillary items from the dashboard as we could including the floor liner. The cause: We think the main short was on a sub loom that goes to the instrument cluster back to the 28 pin connector on the fuse board. The cable appears to be as factory fitted and it wore through the insulation on the steering column support. Two other wires in the same loom were melted to this wire so we ended up replacing three wires by disconnecting the multi way connectors from the fuse board for this loom and pulling them back through the bulkhead to the radio hole.

This sounds hard but the back of the fuse board is big enough to get your hand through We then pulled the 2nd part of the same loom from which feeds the ignition, lights and instrument cluster through towards the right of the van so we could fix the length that runs from the radio hole and behind the instrument cluster.Welcome to world's most trustworthy automotive forum.

Thread Rating: 21 Vote s - 2. Reputation: Is it possible to do it offline or only online? Can anybody give me any information, link or etc? I used search on this forum, and I can't find any threads referring to my problem PS.

Car is after crash, now it won't start I think because there is problem in AdBlue module. Engine is good, starter also. Reprogram SCR module 2. Clear errors 3. Check fault codes PPPS. Already checked. I mistake a pyrofuse with normal fuse. How to check is pyrofuse not used? I checked voltage after pyrofuse point where you connect charger and ground and there is about 12V.

I bought crashed car and it should be everything, maybe it can't start because there is a self-made anti-theft system, but the engine with gearbox was take out, and lot of parts in cabin seats, carpets, dashboard, console, doors and etc A 13AD00 The output stage of the heater for the crankcase ventilation system has a short circuit to ground.

A 14E The output for the heater of oxygen sensor 1 cylinder bank 1 has a short circuit to ground. A C00 Component 'Y Coolant pump switchover valve ' has a short circuit to ground. A Component 'Y94 Quantity control valve ' has an open circuit. A 11A Component 'Y74 Pressure regulating valve ' has a short circuit to ground. A Component 'M55 Intake port shutoff actuator motor ' has a short circuit to ground.

You have also one buned fuses for MAF and M55 actuator,check in engine compartiment for one 15A fuse! I will check it tommorow, but is car won't start because this errors? All fuses were checked but maybe I skip one of this I don't want to bypass SCR, I need to repair it. As I writed, when I go into module I get info about "Variant of module has changed" and Caution as you can see on photo. Reputation: 2. Did you ever resolve this issue?
