You have a short somewhere in the circuit and needs to find out what is causing it.

What engine is in your van. I might be able to find a wiring
diagram for you.

What is the fuse number that is blowing?

Thanks, its a 1.9 tdi engine and the 15a fuse keeps blowing which is #34 on the fusecard. There is e stripped wire under my engine but the mechanics that have seen it, say its an oil sensor and no need to worry, Im thinking maybe theyr wrong.

Would you know the engine code? 1z, AFN, AJH, ANU, AVG?

I don't think the wiring is the same for all.

It seems I might not have the wiring diagrams after all. I can
find mechanical info, but the wiring might take me some time to find
since we don't have the Sharan in North America.

Ask your mechanic to print you a wiring diagram, then have a look
at what is supplied power via fuse #34.

Disconnect one component at a time and see if the fuse still blows.

If you are lucky, it will be a component / sensor that is faulty. If
you are not lucky, it will be a worn-through wire that is touching
ground / earth that might not be easy to spot.

Good Morning / Good Evening,

I'm still looking for AVG Wiring info. In the mean time, look at
the AHU/AUY to give you an idea of what to check on your engine.

Fuse 34 (S234) is on page 4. Follow the track down, it stops at
112. That means it continues on track 112 (page 9).

On page nine, look for 38 and follow it down. ALL the items that
are attached to 38 are on fuse #34.

On page nine, that would be items N239, N18, N75, G70. Use the legend
to determine what each component is.

The horizontal line "j" branches to page 8 & 10. Follow it to find
the remaining items that are on fuse 34.

Any small rectangle with a number in it (141, 136 on page 9 for example)
also need to be checked. 136 is on page 11 and 141 is on page 12.

I will continue to look for an AVG wiring diagram.

Good luck.

Well, I found an AVG diagram. But, it is for a 2000 model. It
does not show a fuse 34 (at least that I can see).

If you can take & post some pictures of your engine bay (with the
plastic engine cover removed), then I might be able to point out a
few items if you are having difficulty locating them.

Start with that striped wire you mentioned at the beginning of your
post. Tape it up with some electrical tape and see if that makes
a difference.

Be prepared to go through a lot of fuses if you don't have a
short finder or low amp circuit breaker that you can install in
place of a fuse.
