Help with Vag fault codes please

Going by this I guess they have wired the sensors wrong after custom exhaust

Would it be as simple as swapping plugs around and were are they?

Thanks!

The code 18010 has the following possible causes :

a) Weak battery
b) Alternator fault
c) Cables disconnected from battery.

Have you disconnected the battery recently ? Clear the code and see if it comes back.

I imagine that swapping the sensors round will clear the other code.

How is the car performing after the exhaust and tune?

Was running great then this fault code came up and seems to be de-tuned since.

Had a look at the wires and pugs in engine bay and don't think its as simple as swapping plugs...

MIJ origanlly left them unplugged... so i guess they got the wiring mixed up and just left it... Nice one MIJ

the implausible signal is related to the lambda I think, they are very visible and simple to change at the top of the engine bay, left side, two ruberised connections attached to the bulkhead.

just unplug and swap them over, I had that problem and that solved it.

Found the plugs there are four but all different sizes and shapes so not possible to swap?

Is there a wiring diagram about so I can see which plug is which?

The two larger connectors are for the sensors that were relocated. There isa cable tie behind the oil filter. Remove the tie and thereshould be enough slack to enable the connectors to be swapped over. The smaller connectors are for the pre cat sensors.

Did you manage to solve the problem with the sensors?

Well im still waiting for sensor code to come back after deleting....
But looks like it was just a one off after changing exhaust all seems spot on now :D
