Middlebridge 66 is currently being re-commisioned. Part of this process is curing the oil weeps that were noted during the VI (vehicle inspection) Apparently a few of the Middlebridge cars were not fitted with the usual VDO gauges? This of course meant that a different oil Presure switch was required. I called the dealers but no joy, next stop Google, success there was a couple new old stock on Ebay. BUT located in the States. I further Googled but nothing at all in the UK. I had no choice but to go that route so $45 for the unit, $18 postage and to add insult to injury £18.10 To the Post Office for the pleasure of queing to collect it. Gripe over but hopefully I have got the important MESSage across re: the availability and type of Oil Presure Sender as factory fitted to a few of our Middlebridge cars.
