Help Please - My A4 is Driving Me Mad

[Monzta]

Having been off the road for three weeks I thought I'd finally solved my problems. I'd fitted a secondhand Central Electronic Control Module and the car was starting and ticking over fine and my wipers were once again working.

I cleared all the codes then took it for its first drive today and within a quarter of a mile the Check Engine Light was on and the car was in limp mode so I turned around and drove straight home. I ran VCDS-Lite and it came up with the fault codes below (highlighted in bold).

I'm not too bothered about the SatNav and Radio codes, it's the engine, ABS and wiper ones that are the issue.

Any help in decyphering them and pointing me in the right direction would be hugely appreciated. I'm self-employed and need this car working ASAP.

I've Googled the various fault codes but I'm not getting any particular remedies that tie in with all of them except perhaps there being a problem with the engine wiring loom.

My car is a 2004 1.9 TDI SE Avant with the AVF engine.

The relays under the ECU can get water damage.
Not sure if the relays mentioned in your scan are located there.

I think there has been a minor flood in the ECU box in the past as one of the relay connections looked a bit corroded. I cleaned it up as best I could and fitted a new relay but still no joy. It would help if I could find out what each of the relays does. With the Hondas I've had in the past it tells you what each relays for on the lid.
