Title: Battery drain on 2.5TD
Post by: mc9 on 16 December 2011, 20:20:12

Just had a diagnostic check on the car. No fault codes found but the tester did find a parasitic battery drain of 0.35 amps. He suggested that an electronic time delay module failing to turn off might be the problem. The courtesy lights do go off as expected but can the electronic timer module remain active and cause a current drain?

Anyone seen a problem like this? Any fixes?

Thanks

Sadly, it'll be a process of tedious elimination :(

you can get a cheapo amp meter from (maplins) which fits in the place of the fuse, thus showing which circuit the drain is occuring :y

It's a "der" moment. One of the rear courtesy lights was on continuously. It's so dim (don't say a word) that nobody noticed, even at night. Not even the two auto-electricians who examined the car.

12V x 0.38A = 4.6W, sounds about right.

Goes to show -- always check the OBVIOUS first  :-[

Cheers
