Ok, I'll put the ecu and map sensor back as it was and try to trace atmospheric sensor and dpf sensors, it seems to have been a previous fault anyway as the wiring is replaced and soldered for map, otherwise i suppose I'll just have to try a different ecu. And open to any suggestions, Thanks

My intermediate connector was bypassed already and the 4 wires at the ecu were un-braided so clearly has the same issue before. I must have a different issue causing same codes if its supposed to creep up near 5 volts, I had no coffee before replying to @J.R. I should mention,when I unplug my map sensor the electric water pump comes on making an awful noise until plugged in or key off

The whole loom is insulation tape from the ecu to the engine.. I've stripped some of it back and its wet inside the tape. Am I as well off to strip the whole loom off and re tape with the proper furry tape lol. Thanks too for the effort and replies lads, tiring pretty quick of this issue

The 4.7 is coming out of the ECU to an open circuit.. snipped wire.. I'd imagine it should be 0v coming out of the ecu as it is a signal input as you say should be getting 1 to 2.5 volts from map sensor to the ECU.

I have vag com and Delphi Autocom, why would there be 4.7 volts coming out of the ecu to wire 2 and 4 on the map sensor..

When I snipped the signal wire #2 and tested voltage on ecu side it is 4.7v and no 4 was 5.7.. but when testing with map plugged in, 2 was 2.46v and 4 was 1.6v

So I've been testing again with my multimeter, the two signal wires are 4.7volt and 5.3 volt from ecu with the wires cut at ecu connector so the power is definately coming out of the ecu, not a short in the wiring harness Is this probably a short inside the ecu possible water damage.. or is it possible that the atmospheric pressure sensor by the cabin filter, is shorting somewhere and sending power back into the ecu and back out to the map sensor..

Are u sure that is the right diagram as the ecu pins are different numbers to what I have continuity with Are u sure that is the right diagram as the ecu pins are different numbers to what I have continuity with

Hi, I dont have any wiring diagrams for this car but the 4 wires from the map sensor go direct to the ecu.. And the intermediate connector is bypassed directly to the map sensor.. I only have vcds and Delphi Autocom which dont test the voltage.. Literally lost now apart from changing ecu..

Thanks to whoever for moving to the right section, Forgot to mention, I'm on the 3rd map sensor, 051c 3 bar standard map, And voltages with key on eng off, 1 is ground 2 is 2.45v 3 is 5.00v 4 is 1.60v. Thanks

Evening everyone, I'm probably in the wrong section but I'm not sure where to post.. I have a 2010 superb cbbb 2.0tdi 170ps I have constant limp and glow plug light flashing. 2 faults- p0238 map signal too high P0113 IAT signal too high.. I cant seem to find a wiring diagram that gives the voltages to test with ignition on. I have checked for continuity from the ecu and all 4 wires are good, have been replaced from near the fusebox, to the sensor.. theres no continuity across the 4 wires either, from the plug to the Also my atmosphere sensor keeps toasting every few months.. Is there anything else on this circuit? Or is my ecu going in the bin. Thanks

Old post but my fuse box is 12v constant, any other suggestions for ignition feed. Cig lighter is constant too

Ya I had figured it was a bad idea but thought the solid clutch disc shouldn't really have any play so essentially the same as the dmf clutch disc. And I had the question at the back of my head saying, should I send it?. Thanks for the reply, i will just replace the smf kit as I have a bad rattle from a loose spring on the disc

Hi all, probably a stupid question but just wondering if anyone had tried it. Can i use the luk clutch disc from dmf with a solid flywheel and pressure plate, it fits perfect in the solid flywheel so no reason it shouldn't work only difference is the springs

Hi everyone, I'm from cork, Ireland and have 2 Octavias and 2 superb, mapped and modded, (cant leave anything alone) 😂 . Thanks for the add
