Volvo P1800E-Bosch 0 280 100 010 MPS defective diaphragm-repair possible?

Hello,I own a 1971 Volvo P1800E, chassis no. 33744, equipped with a Bosch D-Jetronic system and a Bosch 0 280 100 010 manifold pressure sensor.My mechanic has tested the sensor. The electrical part is working correctly, but the diaphragm is defective.The sensor is extremely difficult to find and the only replacement my mechanic has been able to locate costs €1,560 excl. VAT.I contacted Bosch France through their press office. Bosch investigated the possibility of repairing the sensor but unfortunately came back with a negative answer. Their technical contact then referred me directly to the documentation on Jetronic.org concerning D-Jetronic manifold pressure sensors.I understand from the information available here that these MPS units can sometimes be repaired by replacing the diaphragm and then recalibrating the sensor.Would it still be possible to repair my Bosch 0 280 100 010, or could you recommend someone who can currently do this properly?The car and the sensor are currently in Saint-Malo, Brittany, France.Thank you very much for your help and for all the technical information available on this site.Best regards,
Eric

Hi Eric,

I think that I still have a 010 MPS in my drawers. I will check and let you know by PM.

Hi Volker,
Thank you very much for your quick reply and for taking the time to check.
That would be great news. I'll wait for your PM. 
Best regards,

Hi Eric,

unfortunately I did not find a 010 MPS, only 015 for Volvo.
