Today I have mostly been..

interested to know whether Mercedes parts with a Mercedes part number are all the same, or different for different models?

You see, today we drained the coolant and changed the engine temperature sensor, and the thermostat. Both items on the car and those replaced were genuine Mercedes parts, and both had identical part numbers. however both had slight marking differences.

The car now ticks over better due to the temperature sensor, and the temperature gauge reads higher, and the heater is hotter due to the thermostat.

Neither part we replaced looked old.

WTF?

We also changed the ATF.

What a bitch of a job, not draining and refilling the fluid, and removing and refitting the filter - that was easy, but derusting and liquid metaling the pinhole which subsequently appeared in the ATF sump. If you have an older car I would check your sump where it sits near the exhaust - pretty fatal to lose your fluid.

I have enquired of a friendly breaker for a replacement.

Hate to say it but cost cutting would dictate a plastic sump - in this instance it would be better.

Oh, and the fuel pump sprang a leak from its casing - a replacent at £65 arrives from GSF tomorrow. MB wanted £182.

And we replaced the Lambda too, that was well stuck in the exhaust. It has cured the hunting we had at tick over. I think it was the one Fritz fitted from new, 192000 miles later its still working, but not correctly.

I was reading the thread about warranties on the general forum today. Had to smile - I've still spent less on this car than some spend on their warranties, and being older its generally better. And it will still be worth £500 when I move it on.

What a bargain!

Do you mean the temp sensor and the thermostat had the same part numbers as each other?? Surely not!!

Or do you mean the part numbers were the same as the part numbers of the items removed from the car? More likely, I hope!!

It would make sense that the numbers are the same as the originals, though, surely?

I've replaced a gearbox sump before now. The independent I use to service cars before sale spotted it so I bought a new sump from MB - it wasn't too expensive

With the old sump off the car he probed the rusty bit with a screwdriver and a chunk fell away - enough to drain all the fluid out in a minute or two

You were right second time, the new and old both had the same part number. So why such a difference when changing them. I checked on the history - neither part was old.

Maybe the garage who did the work didn't fit new parts...

or they deteriorate really quickly.
