Lambda B1 S1 Sensor, battery fuse tray & alternator wire replacement

[RC81]

Hi, At the weekend I thought I would complete a few urgent jobs on the golf 1.8T.
Firstly the B1 S1 pre Lambda Sensor was throwing up 3 codes, so I pulled the old one out to find it was a pattern part, not an original.


Left, the pattern part. Right, A Bosch oem sensor


Couldn't get the car in the unit, so got it jacked up instead

Then had to replace the melting battery fuse tray and the Positive Alternator wire.


So found a very good 2nd hand replacement on eBay for a few quid


So made a heavy duty Positive wire to replace the existing corroding one. It was causing heat & resistance.


Replacement fuse tray and beefed up wire in place.


So after a few hours down the lock-up, some nice dry mild weather, a few tools a job well done i'd say.
Oh and the fake Lambda sensor can go in the bin!

That fusebox/tray looks like new! Nice neat job there sir!

I was lucky really, I scoured eBay for ages to find an original VW fuse tray and found this one in near mint condition. But the main positive wire was getting very hot as the pics showed. So needed urgent attention. And the ECU was throwing up a code for this too.
Cheers though, I enjoy a satisfactory job well done
