Can you ID these Parts?

The metal frame behind battery and to the right, it seems to contain springs...

Behind battery and to the left, near black box fuse.

Cheers!

Hi Mike,
looks like resistors to me that might control the interior heater fan speed.

Regards
Mike

Pics

The first pic as Mike states is the resitor for the heater motor.

The second pic just looks like a connector where two looms meet.

Cheers, I was poking around looking for something else (the famous R16
resistor) and wondered...

Yes, its true, for all the W201 and W124 owners, here is a simple modification that will yield you better throttle response and more power. While researching some other options for upgrading the ignition, I came across some interesting data on the MB service CD. On the Euro spec MB's ignition, there is a item called a reference resistor or R16/1, it is a manually adjustable dial that allows you to retard your ignition timing.

Does anyone know anything about this?

Mike.

In think the R16 dial thing you're talking about is on the passenger side front wing and is near (on) the ignition amplifier pack in the W201s. There is a small knob which can be removed and refitted in any one of three positions. Its purpose is to enable the engine management system to configure the ignition timing to compensate for differing qualities (octane rating) of petrol.

The first position retards the ignition timing and is for (from memory) 92 octane and less, the middle position is I think for UK type unleaded and the third advances the ignition timing and is for premium quality petrol, the unleaded equivalent of the old 5 star.

It is most important that the plug is set correctly. If it's in the low quality petrol position the engine will produce less power but no harm will be done to the engine. If however it's set to the highest position it will cause 'pinking' and engine damage.

Hope this helps.

Hmmmmm I cant find anything except the igniton system control unit (TSZ ignition) and a 9 pin diagnostic socket.
