Hello. I'm new to the forum.

I've just taken delivery of a new Superb Estate Elegance 2.0tdi which I will be leasing.

Following on from some earlier threads I am looking to improve the reversing lights, but before I play would like to know the fuse location and rating so that I can establish if it's possible to put additional load on the circuit, and where to look when it goes pear shaped!

Unfortunately the manual doesn't seem to list reversing lights on the circuit list, so I would appreciate any pointers?

The reversing lights are powered directly by the vehicle voltage control unit (J519), with all its control circuits via a 0.5 mm2 black/blue wire. I wouldn't risk adding any consumers to this circuit. If you do, use a relay to power those extra consumers without adding any (significant) power consumption to the reversing light circuit.

Yes, thanks for that.

This was my thinking too.

I am looking to fit a relay with actual power taken from the 12V socket in the boot.

I was just interested to make sure that I knew where to isolate the feed if I needed to, but surprised that reversing lights don't get a mention in the fuse listing.

... I am looking to improve the reversing lights ...

Welcome to the Forum!

In what way are you trying to "improve" the reversing lights?

Hello Ray, thanks for the welcome.

Although it's early days, I am anticipating finding the standard lights inadequate for my use.

In my job I often get called out at night to unfamiliar locations, narrow lanes with limited places to turn etc. I do have parking 'beepers', which are fine for parking but aren't much use when you need to reverse maybe half a mile in a lane. For that I would like to be able to see in the mirrors.

A colleague in my office also has a Superb estate and has always complained about the reversing lights.

My thoughts are either to try to improve the existing lights or fit some form of auxilliary lighting at the rear.

Power could be taken from the 12V aux outlet in the rear ns panel.

On a previous vehicle I fitted a lamp inside the rear door for this task. (Legal as a work light!)

It does seem odd that there is no mention of a fuse for the reversing lights in the manual.

@scimitarsims: read my post #2 above, in which I explain why there is no separate fuse for the reversing lights, and why this isn't so odd.

Hi andrehj.

Perhaps not odd, but doesn't seem like good practice. If a bulb filament fails it can sometimes draw a high current momentarily.

If this occurs in the Superb which fuse blows

0.5mm2 cable will have a current rating around 10A, so presumably it's fused somewhere below that value.

I mentioned that there was no separate fuse for the reversing lights. But of course there is a fuse for these lights.

The right fuse is mentioned in your owners manual: It's F1 (in the Fusebox near the battery) for the right lights and F47 for the left lights (both front and rear). According to the electrical diagrams in Elsawin both are 30A and are connected via a 4mm2 cable to the control module J519.

However, I'm almost certain no fuse will blow when the outputs of J519 are shorted. Most probably this control module has a current limiter on its output, like every modern control module (in cars or automatic machines) has.

Thanks for the info andrehj
