Hi Emanuel
your polo seems to have a problem with the diesel pressure sensor,
I am sure when it loose it's power you see the check engine light on.
it should be connected to a diagnostic machine, you'll see that I am right.
good luck

Polo Coupe 1043,1992, Will not start, can be bumped started, sometimes!!, theres a strange clicking noise from under the air box, when the ignition is on and sometimes the oil pressure light comes on when the car gets upto temperature, then I lose all power and then the engine cuts out. I've recently changed the dizzy cap, rotor arm and battery, all the leads are new ish along with the spark plugs. The previous owner has changed the head and done all that, leaving much of the engine loom unlagged and bare. Could this cause a problem on some of the electrical systems?

this a map sensor, probably just need the sensor replaced, it measurese intake vaccum and adjusts air/fuel mixture accordingly

this is a turn in caliper, meaning that as you try to compress the piston, you also need to rotate it clockwise. you can buy tool for this at nearly any parts store, and is fairly inexpensive.
Testimonial: "Thank you for your assistance. I found out the turning piston part by mistake, a day after I posted the question, when I tried to use a G-Clamp."

Hi,
It is a wiring fault, but they are looking on the wrong end. You will need to have a VW dealer "repin" the electrical connector at the throttle body. What this means is, the dealer will take apart the connector, cut off the old pins and crimp on new ones and reassemble the connector. This is a common problem on drive by wire VW's. The dealer has a bulletin on the problem and I don't know why they missed it. They will probably have to order the connector kit however. Good luck!
