Customer Question
1984 300D Mercedes. When...

1984 300D Mercedes. When I come to a stop/let go of the gas the "battery" light flickers - sometimes all of the lights flicker, even the low fuel indicator. Not sure why.

Mechanic's Assistant: Thanks. Can you give me any more details about your issue?

Started to notice some smoke at idle out the exhaust.

Hi there. Welcome to our site!

PLEASE READ THIS FIRST:

If you’re thinking on working on the vehicle yourself, all my knowledge and resources won’t help unless you…

… have basic knowledge and mechanical skills, and…

… have whatever tools and equipment might be needed for a proper diagnosis

The flickering lights could be telling you there is something wrong with the charging system - could be something as simple as loose alternator belt, or not so simple as a faulty alternator or internal voltage regulator. Looks like a thorough visual inspection and charging system check are in order.

Please let me know if you have any other questions.

Best regards.
