W124 Fuel Pump/Kickdown Relay

[MJK 24]

My fuel pump relay has failed and the car won't start. When I bridge '30' and '87' I can hear the main pump buzz. With the relay fitted, nothing. I've opened it up and there's no obvious issue re dry joints etc so it's looking like I need a replacement.

Where's best to go?

Part number is 002 545 05 05

Many thanks in advance for any pointers!

£144.72 inc VAT at the main dealer.

I can't see any used or at the usual NOS merchants. GSF appear to do aftermarket ones for £104.20 but at that price you might as well get the real deal.

Just rang Liverpool Mercedes this morning and was quoted £94 plus VAT! Did they pity me after recent expenditure?!

Just fitted my new relay. Running like a Swiss Watch oncemore!
