I was told that Beru makes ignition modules for W126 V8s (TSZ 8 z), but are they 100% equivalent/compatible with original equipment?? (Bosch #0 227 100 042 / MB#002 545 26 32)
Beru are tempting as they are a lot cheaper then Bosch for new ones, and still worth thinking about comparing to Bosch rebuilds (exchange).

The Beru module should be fine. The Bosch ones were nothing to get excited about...they did fail.
Why not use a module that's a bit more modern? I've been using the Bosch #0 227 100 114 in their place for 5 years. If one ever breaks I'm sure I'll hear about it. Same design, same connectors...just an integrated circuit type instead of a hard-wired version.

Hi Randy,

Could you tell me what cars use the modern module you mentioned?

Thanks and regards,

Bill

Hi Bill,
The only car it came on was the 84 and 85 190E.
