Fitted new downpipe...flat battery, and now a sensor fault

[Rob.]

I managed to get my new downpipe fitted a couple of weekends ago, but struggled to get the post-cat lambda sensor off of the old exhaust.

When I finally removed and re-installed that, I tried to start the car on Saturday and it was dead. I ran VCDS, which gave a load of low voltage warnings (and checked the batt with a multimeter) so left it to charge for a few hours, then she started fine.

However, I've now got a couple of faults that won't clear: "engine oil temp sensor - implausible signal" and "sensor for engine oil level/temperature - opens or short to plus". The dash also warns about it when starting up.

I don't recall doing anything to these during the work (only the O2 and MAF were unplugged), so is it possible the low voltage has somehow killed it?

Thanks.

No one?

Sometimes i find some errors won't clear when you use clear all errors. And i have to go into that block to clear the error.

they just might of been there before you fitted the new down pipe? when was the last time you ran a test before then,

[Rob.]

Definitely wasn't, as it's actually saying "oil sensor garage" on the dash when I start her up...wasn't doing that before the flat battery!

[Rob.]

Yeh, so basically I must have unplugged the oil sensor plug and forgotten to put it back in 

Awkward.

All sorted now ? Was it just the oil level sensor ?
Think the low voltage problem is unrelated to what you did.
